HOW TO CATCH FISH EFFECTIVELY, OSPREY-STYLE

I have featured the wonderful photography of Phil Lanoue before. He specialises in taking sequences of the larger birds, many of them as they hunt for fish: herons, egrets, anhingas – and ospreys. Here is a remarkable sequence of an osprey showing its fishing skills, with a surprise ending that I won’t give away.

Pretty cool trick, huh?

‘CHECK OUT THE WEB’: SEMIPALMATED PLOVERS ON ABACO

July 17, 2015 by Rolling Harbour

‘CHECK OUT THE WEB’: SEMIPALMATED PLOVERS ON ABACO

“Semipalmated”. You what? Come again? Ehhhh? My reactions to the word until embarrassingly recently. In fact until the steep learning curve involved in writing a bird book made ~~some~~ all of the terminology clearer. Plovers and sandpipers both have semipalmated versions, and I’ll take the semipalmated plover (Charadrius semipalmatus) first.

WHAT SHOULD I LOOK FOR?

A small shorebird with a grey-brown back and wings, a white underside with a single black neck band, and orange legs. They have a brown cap, a white forehead, a black eye mask and a short black bill with an orange base to it. And feet to be discussed below.

WHERE DO THEY LIVE?

Their summer home and breeding habitat is on the beaches and flats of northern Canada and Alaska. They nest in scrapes on the ground right out in the open. In the Autumn these little birds set off on long journeys south to warmer climes until Spring: the coasts of the southern states, Caribbean and South America. On Abaco, they are fairly common in certain areas including the beach at Delphi. Like other plovers, these birds are gregarious and will mix in with other shorebirds – which can make them hard to pick out in the crowd.

GET ON WITH THE ‘SEMIPALMATED’ BIT, PLEASE

‘Semipalmated’ refers to the partial webbing between their toes. There are different degrees of palmation, as these handy graphics demonstrate:

Semipalmate: in practice, very hard so see in the field e.g. plovers & sandpipers

Palmate: full webbing across the ‘front’ 3 toes, e.g. gulls

palmate

Totipalmate: all toes are fully webbed e.g. cormorants

totipalmate

Nonpalmate: please supply own imagination

Gregarious flight: there are sandpipers in the mix (clue: long bills)

WHAT DO THESE BIRDS EAT?

Semipalmated plovers are much like any other small shorebird foraging on beaches and foreshores. They eat insects, crustaceans and worms. Here is a bird in a promising place for its preferred diet.

ANYTHING ELSE TO LOOK OUT FOR?

Like other plover species – Wilson’s and Killdeer for example – a semipalmated will use the ‘broken wing’ ploy to lure a predator away from a nest and the eggs or chicks in it. As it flops about pathetically on the sand looking vulnerable, it actually moves gradually further away from the nest. If it comes to the crunch it is able to take wing rapidly, leaving a very puzzled predator behind.

BLACK-BELLIED WHISTLING DUCKS REVISITED…

July 15, 2015 by Rolling Harbour

BLACK-BELLIED WHISTLING DUCKS REVISITED…

The first ever Black-bellied Whistling Ducks recorded for Abaco arrived last June. Six birds turned up on South Abaco in the Crossing Rocks area and slowly worked their way north via Delphi, Bahama Palm Shores and Casuarina. They split up into smaller groups. Two were seen near the airport. Eventually, after 3 weeks or so, the sightings and reports ceased. The BBWDs had moved on, presumably to Florida.

I mention them now because this June, a flock of 13 birds arrived on a golf course in Bermuda. The only previous recorded sighting of the species had been a single bird spotted in 2006. Within a couple of weeks, the birds had disappeared again. It’s strange that in consecutive years, June sightings have occurred on two islands where they are not a known species. I happen to have taken some photos of BBWDs elsewhere in the meantime, and I thought these pretty ducks deserved further exposure…

A BBWD LOVE STORY

Hello! Would you like to preen with me?

Yes I would. As long as there are no paparazzi around.

Mmmmmm. This is so great!

I’d like to look after you and protect you

Let me take you under my wing…

GODDAMMIT. Pigeon photobomb!

MARK CATESBY: PIONEERING NATURALIST OF EARLY c18

MARK CATESBY: PIONEERING NATURALIST OF EARLY c18

There’s been (yet) another abrupt side-swerve away from a topic I’d intended to post about, resulting from a newspaper article I read over the weekend. This concerns what was gushingly described as “the ultimate coffee table book”, a facsimile of Mark Catesby’s renowned work, The Natural History of Carolina, Florida and the Bahama Islands.

Catesby (1682 – 1749) was a pioneering English naturalist and artist who published his magnum opus based on a number of expeditions he undertook from 1712 onwards. His was the first ever published account of the flora and fauna of North America, and the 2 volumes (with a supplement) included some 220 colour plates of the creatures and plants of land and sea that he had come across.

Mark Catesby – Angelfish

Mark Catesby – Queen Triggerfish

Catesby’s growing fame as a botanist led to his undertaking expeditions on behalf of the Royal Society to collect plants and seeds in Carolina. He widened his researches both in America and to the West Indies, collecting plants and fauna as he went and sending them back to England. Among other discoveries, he was one of the very first people to observe and record the occurrence of bird migration as a twice-yearly phenomenon.

Red-legged Thrush in Gumbo Limbo Tree

Eventually, in 1726 Catesby also returned to base and set about writing up his findings and painting what he had seen. He learnt how to etch printing plates, and gradually the illustrations became more sophisticated, starting without backgrounds then including plants with the animals and birds. The whole project took him some 20 years; quite soon after completing it, he died.

CATESBY: THE VIDEO INTRO

WHERE IS THE ORIGINAL WORK NOW?

Catesby’s original drawings were bought by King George III for £120 (a very considerable sum in 1768 – my quick attempts to discover how much suggest ± £200,000) and have remained in the Royal Family ever since. This treasure is kept in the Royal Library of Windsor Castle, the property of HM QE2, though it is occasionally exhibited elsewhere. Later facsimiles of the original were produced, of which some 50 survive today.

Mark Catesby – ‘Bahama Titmous’ (Bananaquit)

SO WHAT’S ALL THE EXCITEMENT ABOUT NOW?

Addison Publications has printed a very limited edition facsimile of 60 in 4 lavish volumes, printed one at a time, “to mark the 300th anniversary of Catesby’s arrival in the New World”.

The cost per set? A stonking £39,500 ($61,330). Now this may sound a great deal of money for a modern copy of an old book and it undoubtedly is. But here’s the Christie’s Auction catalogue entry for one of the early facsimiles. Mmmmmm.

Delphi afficionados, especially any who have stayed in Room 1, may recognise 3 of the illustrative images I have chosen – the Spindalis, the Bananaquit and the Grassquit. No, I don’t mean the actual species, I mean that Catesby prints of them are tastefully hung on the walls. I can never decide which of the 3 is my favourite…

LIMESTONE CAVES ON ABACO: WELL WORTH LOOKING INTO…

LIMESTONE CAVES ON ABACO: WELL WORTH LOOKING INTO…

I have written several posts in the last few months featuring Brian Kakuk’s amazing photos of the underwater caves of Abaco. These caves, mostly beneath Abaco’s pine forests, are fabulous treasures of rock and crystal. A recent post example can be seen HERE. I have also featured some of the famous Blues Holes of Abaco from time to time, for example HERE. So now it’s time to turn attention to ‘land caves’, the dry(ish) limestone holes and caverns that are dotted around Abaco, especially in the South, and bear witness to aeons of geological development through erosion.

The coppice and extensive pine forests are pitted with holes of widely varying sizes. I’m way out of my depth here, geology-wise (polite corrections invited), but this sort of landscape is I believe known as KARST. This term presumably includes Abaco’s ‘dry’ holes, the blue holes and the substantial network of underwater caverns. Small examples can readily be found in easily accessible places such as non-dense coppice. We were very surprised when we pushed our into the coppice bordering the Delphi Club guest drive and took a closer look at a hole. Although the weather was hot and dry at the time, you will see that the hole has some form of micro-climate, with damp walls and interior and wet-climate plants like small ferns and forms of what I take to be moss and algae.

A HOLE NEAR HOLE-IN-THE -WALL – LARGER INSIDE THAN IT LOOKS

THE CAVE-DWELLERS OF ABACO: THE FABULOUS PARROTS

Among the best-known special residents of Abaco are the ground-nesting parrots, gorgeous birds that I have often featured in the past – see the parrot page HERE. Not so long ago, their numbers had reduced to an unsustainable population – fewer than 1000 – that faced extinction. The creation of the National Park covering the pine forests where they breed, coupled with a vigilant and intensive conservation program, have reversed the trend. There is now a sustainable breeding population again, exceeding 3000 birds.

The only other breeding Cuban parrot population in the Bahamas is found on Inagua, where they nest conventionally in trees. There is a very small non-breeding population on New Providence. Abaco’s cave-dwelling subspecies of the cuban parrot is unique. Here’s an insight into how they live, deep in the pine forest, during the summer breeding season, with many thanks to Caroline Stahala, the scientist who spent some 10 years researching and protecting the parrots.

THE BREEDING SEASON: NEST, EGGS, HATCHLINGS, FLEDGELINGS…

HOW BIG DO THE ‘DRY’ HOLES GET?

TBH my personal experience is somewhat limited. I believe there are large, sea-scoured caves along rocky parts of the south coast, but those are rather different from the eroded ground holes discussed here. As so often I rely on Mrs RH – far more intrepid than me – and her exploring skills. The cave shown below is right down at the far south of Abaco, at Hole-in-the-Wall, hidden in the coppice along the ‘Soldier Road’ from the T-junction (we are talking rough tracks here – very – not proper roads) towards the lighthouse.

The rock is far more colourful than you might expect

WHEN A BIG BILL JUST MAKES YOU SMILE… WILSON’S SNIPE ON ABACO

July 6, 2015 by Rolling Harbour

WHEN A BIG BILL JUST MAKES YOU SMILE… WILSON’S SNIPE ON ABACO

Wilson’s snipe Gallinago delicata is a plump little bird that is classified as a shorebird. But unlike some, it is not confined to the shore and immediate hinterland – marshland or brackish pond regions are also favoured habitats. Until recently (2003) the Wilson’s was treated as a subspecies of the widespread Common Snipe, before being accorded its own species-status. Something to do with white on the wing edges and a couple more tail feathers. If you want to know who Mr Wilson was (who also ‘owns’ other birds such as a plover and a phalarope) you can find out HERE.

A Wilson’s Snipe on Abaco (but not on the shore…)

The snipe, in common with several species such as the woodcock, willet and dowitcher, has a notably long bill. The header image is one of the best I have come across that clearly illustrate it, and comes from the extensive archive of the excellent BIRDS CARIBBEAN. The naturalist concerned noted “…check out this remarkable bill. If you have not held a shorebird like this in your hand, the bill is pliable, flexible, and innervated. The snipe feels its way through the muck and then plucks the worm out like tweezers”.

SNIPES AND SNIPERS

The snipe has the misfortune to be a game bird. In the c19, its populations began to reduce due to habitat destruction – especially the draining of marshland – to which it is still vulnerable, of course. But more serious was its increasing popularity with hunters as a difficult bird to shoot, with its fast, jagging flight. A hunter skilled enough to shoot snipe successfully became known as a “sniper”, a usage coined some 200 years ago. I imagine the verb ‘to snipe (at)’ a person derives from this usage, meaning to fire off a quick, accurate, possibly hurtful remark.

Despite these drawbacks, there are enough snipe for the species to remain IUCN-listed ‘least concern’. In the Bahamas, they can be hunted between autumn and spring. This is the relevant page from the BNT HUNTERS’ GUIDE

WILL I SEE WISNs ON ABACO?

Although the Wilson’s snipe is one of the most widespread shorebirds in North America, they are far less readily found on Abaco. For a start, they are migratory in the Bahamas, and only resident in winter (broadly, October to March), their non-breeding season. So don’t expect to find them during your pleasant stay in June. Secondly, they are classed as ‘rare’, one grade harder to find than ‘uncommon’. Thirdly, they are shy and well-camouflaged. Unless they choose to be out in the open – foraging in water, or maybe standing on a post – they can be very hard to see. And in winter it seems they tend to hunker down more and fly less than in the breeding season. Maybe they show more in summer because they know it’s the closed season for hunting… Compare the next two images, one taken on Abaco in winter, and one (cheers, Wiki) elsewhere in the summer.

DO SNIPES HAVE A DISTINCTIVE CALL THAT I WILL INSTANTLY RECOGNISE?

Not really, I’m afraid. Not easy for an amateur (me). They have a variety of vocalisations – calls, flight calls, and songs. They also make a sound called ‘winnowing’ with their tails while in flight. Here are a few short examples.

Now that the wonderful Crossley Guide ID bird images are available ‘open source’, I shall be including them in future species posts. When I remember. Their advantage is that in one image you can see all aspects of a paricular species – gender, breeding plumage, typical ‘poses’, in flight and so forth. A truly great resource for bird identification.

SHARING SHEARWATER SEASHORE SHOCK ON ABACO…

June 29, 2015 by Rolling Harbour

SHARING SHEARWATER SEASHORE SHOCK ON ABACO…

I return reluctantly to the “Great Shearwater” phenomenon to give, I hope, closure to the topic for this season and with luck for several years to come. A great many people have engaged with the debate about the large number unfortunate birds found either dead or dying in the water or (especially) on the beaches of Abaco and beyond. You can see the original post, a tabulation and map based on the reports I received or came across, and the views of the experts HERE.

This occurrence appears to have declined considerably from its peak last week, presumably because the migration has moved rapidly northwards. Already, reports from the eastern US Atlantic coast (e.g. Cape May) of a great shearwater influx are coming in, so we must hope that the attrition rate in the Northern Bahamas has stopped, or will stop within the next few days. This is evidenced by this FB clip from Tom Reed, a photographic contributor to THE BIRDS OF ABACO

The ABA (American Birding Association) has taken an interest in the problem on Abaco, and reported the incidence of shearwater die-off HERE. For the sake of completeness, I have updated reports I have received or found over the last few days below, together with an updated distribution map. More sad images are included because, pitiful though they are, photographs are of real assistance in the study of migratory die-off. For example, it is likely that juvenile birds are more likely to be affected by exhaustion in the course of their 10,000 mile journey than adults. Photos enable an assessment of the age of the birds to be made.

Exhausted shearwater, Delphi beach. Is this a juvenile, less able to make a huge journey than an adult?The yellow tip to this bird’s beak shows that it is a different species of shearwater, the Cory’s. Like the Greats, these birds are also rare transients on Abaco, and also make long-distance migrations. A Cory’s was photographed a couple of weeks ago swimming happily off the Delphi beach. This one has obviously run out of stamina. It has the chance to recover, but it is vulnerable in this state; and turkey vultures are quick to move in on fatalities…

UPDATED REPORTS (SINCE JUNE 24) IN RED

Delphi Club Beach – 20 plus + 1
Schooner Bay – 5
Bahama Palm Shores – ‘many many’ dead birds washed up on the shore
Casuarina Beach – 1
Cherokee (Watching Bay) – 3 or 4
Cherokee (Winding Bay) – 4
Little Harbour – 3
Marsh Harbour area – about 5
Great Guana Cay, southern end – 1 (possibly a gull)
Tilloo Cay – 13 at least on Junk Beach, more than ever seen (see photos below)
Elbow Cay – 2 + 1 Atlantic side beach near Abaco Inn
Elbow Cay – 2, North End
Green Turtle Cay beach – 2
Green Turtle Cay, offshore – “a lot in the water”

also Exuma Sound (5 birds), Shroud Cay Exuma (gull?”), Briland Beach,Harbour Island Eleuthera (“some” + 4) , and Church Bay, South Eleuthera – 10 + 2

Ellen Bentz, who reported the Church Bay birds, has frozen 3 of them for research purposes; it will be extremely interesting to see what results from their examination, from the ages of the birds to condition to likely cause of death. She also took photographs to aid species identification and diagnostic efforts.

Here is the wonderful Crossley ID guide tableau of great shearwaters, showing every facet of the bird

Great_Shearwater_from_the_Crossley_ID_Guide_Britain_and_Ireland

WHERE DO THESE BIRDS COME FROM & WHERE DO THEY GO?

Sean Giery of the excellent ABACO SCIENTIST has also commented on the recent phenomenon, concluding “…if you haven’t looked up Gough Island, the probable origin of these Greater Shearwaters, do. Use Google Maps to get an impression of how far these amazing birds travel. It’s truly amazing.” By great good fortune, I’ve done the legwork for you… Let’s take a closer look.

Great shearwaters breed almost exclusively the small area of the globe that includes the Gough Islands, Tristan da Cunha and a few lesser-known islands in that area. There is also a small breeding population in the Falklands. Whichever, they are not so very far from Antarctica. Their range, however, is massive and involves long migrations over the Atlantic ocean to the far north – as far as the Arctic – and back each year.

And, as the shearwater flies, this is the distance from the breeding grounds to Abaco; 2/3 of their total journey. Now, factor in a first-season juvenile shearwater facing the vagaries of food supply, weather conditions and stamina… The fact that some die-off occurs every few years at some stage of the migration becomes less surprising.

I’ll conclude with a photo of a great shearwater flying ‘at the shear’, which I am certain is how best we’d like to think of these wonderful seabirds…

GREATER ANTILLEAN BULLFINCH: ABACO’S “POLICE BIRD”

GREATER ANTILLEAN BULLFINCH: ABACO’S “POLICE BIRD”

Following my last gloomy post about the widely-reported die-off of the poor, exhausted migratory great shearwaters, let’s turn with relief to a cheerful bird known to all and admired in coppice and garden: the Greater Antillean Bullfinch Loxigilla violacea. These pretty birds are easy to find and to identify. They love feeders, and they are responsive to ‘pishing’, that irritating (?) noise that birders make to unseen avians in the coppice to persuade them to reveal themselves. Adult males are black with bright red accessories (hence “police bird”); females are paler with orangey accessories; and juveniles look a bit scruffy and patchy. Here’s a GAB gallery to enjoy.

SHEARWATERS ON ABACO: SAD TALES FROM THE SEA

June 24, 2015 by Rolling Harbour

SHEARWATERS ON ABACO: SAD TALES FROM THE SEA

We do not generally do sad or sombre at Rolling Harbour. It’s a beautiful and happy place, and the Delphi Club is a haven of good fellowship and good craic (stemming no doubt from its Irish connections). But I have to report on a sad occurrence on the beach at Delphi and, as it turns out, at many other Abaco locations (and beyond) during June – a notable number of shearwaters being found dying or dead on beaches or else in the sea, their bodies in due course being washed in on the tide.

There are quite a few species of shearwater worldwide, of which 5 are recorded for Abaco. The only permanent breeding resident is the Audubon’s Shearwater, a bird that is quite commonly seen out at sea though not, I imagine, on land. We never managed to obtain a photo of one for “The Birds of Abaco”. I presume there are breeding colonies on Abaco, but not that I have heard about.

As the checklist above shows, three of the other shearwaters are rare transients. These birds fly long migration routes over the ocean and so the casual birder is in practice unlikely to encounter one, let alone get a photograph. The Manx can be ignored as an aberration – the V5 means that one or two vagrant individuals have been recorded since (say) 1950.

Great Shearwater Puffinus gravis - Patrick Coin Wiki

My first inkling that something unusual was occurring came a week ago from a FB post by Melissa Maura, whose wonderful parrot and flamingo photos feature elsewhere in these pages. She said “…on my rugged Abaco ocean beach last week, were many dead magnificent seabirds – greater shearwaters (about 5) and a couple of Frigate birds… They didn’t appear to wash in on the waves, but appeared to have perished perhaps from exhaustion on the beach”. Various later comments suggested that this phenomenon had been noted periodically in the past, the last time 4 or 5 years ago.

This was followed a couple of days later by evidence from well-known birding maestro Woody Bracey that living great shearwaters were in Abaco waters, perhaps confirming that they are in mid-migration at the moment. The one in #2 was “caught” 3 miles off Great Guana Cay.

Then a couple of days ago Jane Mantle emailed me with photos of some dead birds on the beach at Delphi saying that “half- dead birds are washing up on the beach ‘only for the vultures to finish off’. We must have over 20 with more to come”. I circulated these to the ‘usual suspects’ for ID and comment.

I also posted the photos on my RH FB to see if others had seen anything similar. Many thanks to all those who ‘liked’, shared or commented on the post. Here is a summary of the responses, from which a pretty clear picture emerges of widespread recent shearwater deaths on Abaco mainland and Cays.

Delphi Club Beach – 20 plus
Bahama Palm Shores – ‘many many’ dead birds washed up on the shore
Casuarina Beach – 1
Cherokee (Watching Bay) – 3 or 4
Cherokee (Winding Bay) – 4

Great Guana Cay, southern end – 1 (possibly a gull)
Tilloo Cay – 13 at least on Junk Beach, more than ever seen (see photos below)
Elbow Cay – 2 + 1 Atlantic side beach near Abaco Inn
Elbow Cay – 2, North End
Green Turtle Cay beach – 2
Green Turtle Cay, offshore – “a lot in the water”
Man-o-War Cay – 1 by the roadside

Shearwaters at Tilloo Cay (Janie Thompson)

Shearwaters on Elbow Cay (Rudolf Verspoor)

WHAT SORT OF SHEARWATERS ARE THESE?

In the main it looks and sounds as though these are migrating great shearwaters. Woody Bracey has identified several dead birds as ‘greats’ from photos, and one as an alive Cory’s shearwater swimming in the sea off the Delphi Beach. ID is not easy, and a few of the birds found may be gulls. It’s possible that there are some Audubon’s shearwaters among the stricken birds, although since they are resident to Abaco that would go against the theory of an exhausted migratory species that has been blown of course en masse.

WHAT DO THE EXPERTS THINK?

There are a few obvious contenders for the solution to the riddle of the shearwaters, ranging from the frontrunner migration exhaustion to disease and trash ingestion. The evidence of mass deaths over a wide geographical area during a short time probably rules out trash ingestion – although I’m sure the poor creatures must have plenty of plastic bits inside them. Mass disease striking suddenly over one area is seems unlikely. Once those two possibilities are ruled out, the primary cause, covering most instances of the sad and upsetting phenomenon, becomes clearer.

Lynn Gape of BNT posted the view of William Mackin, a seabird biologist who looked at some of the photos and wrote “The five birds look like greater shearwaters. They breed at Gough Island in the South Atlantic. The young begin life by flying 10000 miles to Newfoundland in the North Atlantic. Some do not make it. They wash up on eastern US and Bahamian beaches. It is sad. We should monitor the numbers. The frequency is variable but possibly increasing.”

Tony White, the omniscient Recorder of Bahamas Birds and compiler of the comprehensive and authoritative checklist for the area, writes:

“The dead birds on the beach (and in the water) is a phenomenon that happens every five to ten years. According to the late Dave Lee these are young Great Shearwaters migrating from their natal home in the South Atlantic to their feeding grounds off the US and Canada, Combination of poor food supply and wind conditions in the doldrums lead to their expending all their energy and expiring. It is a normal event for this species and has been recorded many times The Great Shearwater population appears to weather the bad years and do well in the good years. Relevant articles are: Lee, D.S. 2009. Mass die-offs of Greater Shearwater in the Western North Atlantic: Effects of weather patterns on mortality of a trans-equatorial migrant. Chat 73(2):37; Seabird Ecological Assessment Network. 2007. Greater Shearwater Die-off in the Atlantic: June-July 2007. Volunteer Newsletter 3(2):2; and Watson, George. 1970. A Shearwater Mortality on the Atlantic Coast. Atlantic Naturalist 25(2):75-80.

Woody Bracey has now left an informative and perceptive comment: “It’s amazing how far(10,000 miles) these young birds have to travel to their feeding grounds so soon after being fledged. Breeding colonies are on isolated subantarctic islands of the southern hemisphere. Breeding begins in October. Incubation of the single egg lasts 55 days and it is another 105 days until the chick is ready to fly. Each loss of a bird represents much time and effort of a pair to produce a single chick which then has to fly the gauntlet through the windless, often foodless doldrums to reach its northern feeding grounds. So many hazards, so few birds! It’s sad to witness these die-offs but the species still survives. Global warming cannot be helping this species on its journey to the colder, nutrient rich more northern briny destinatioin. Lets stop setting our dumps and forests on fire here in the Abacos. Eventually it will not only affect the Great Shearwaters but us as well”.

I should add that it is reassuring to be able to confirm that, at least at present, the great shearwater is IUCN-listed “Least Concern”

Status_iucn3.1_LC.svg

Tony has asked for all available information Bahamas-wide: “It would be very useful if someone could collect some hard data on the die-off, e.g. when was it first noted and how many birds are found along a given stretch of beach? Check for other species and take a few wings as samples of the desiccated birds. In past events the number of dead birds was much greater on Crooked and Acklin Islands than Abaco. Eleuthera too should be checked if possible”.

Lynn has also asked “Please photograph and count birds found on your beaches and send images and the number counted to me at lgape@bnt.bs. We will send on to William Mackin and Tony White who are keeping records of these occurrences The image with this post is a Greater Shearwater in flight…” (see above, as we would all like to think of these magnificent birds)

Or by all means contact me at rollingharbour.delphi@gmail.com and I’ll pass on any info

SIGNS OF GOOD BREEDING: PIPING PLOVERS IN SUMMER

SIGNS OF GOOD BREEDING: PIPING PLOVERS IN SUMMER

No apologies for writing again about Piping Plovers. This rare bird – only 8000 left in the world – overwinters in Florida, on the Gulf Coast, and to a notable extent in the Bahamas, very possibly on a beach near you. The peacefulness and cleanliness of Abaco’s pristine beaches provide the ideal habitat for the little PIPL to live safe and healthy lives during the winter, in preparation for their return to their summer breeding grounds. And breeding is what they are doing right now, up north. There are breeding populations on the Atlantic Coast, the Great Plains, and the Great Lakes. So I thought I’d feature a few images of what appears to be a rather successful season so far…

One of the best bird blogs around, one that I have recommended before, is called READINGS FROM THE NORTHSIDE. It is written in an informative yet witty style illustrated with excellent photos, and chronicles the daily avian goings-on on Long Beach Island NJ, an important nesting area for piping plovers. There are links with Todd Pover and Stephanie Egger, two scientists from the Conserve Wildlife Foundation of NJ who will be familiar to many Abaconians for the winter work they do with the plovers on Abaco. The photos below have almost all been taken this month as the PIPL chicks hatch and begin to find their feet in a big world.

BARNEGAT LIGHTHOUSE WITH PIPL IN THE FOREGROUND!

Most regrettably, you’ll never see a Piping Plover chick on Abaco. The adult birds have left the Bahamian beaches and flown north before their breeding season begins. These little creatures are both rare and special at both ends of their migration range, so I’ll end with a video from the most excellent CONCH SALAD TV that is dedicated to these tiny wave-chasers. Abaco is one of the main areas for winter research into the piping plover population. Scientists visit the island to find the birds, count them, collect reports of sightings, check and identify tagged birds to determine their origin, and ensure the continuing good health of their habitat, without which the PIPL will be lost. You can find out more about this vital work carried out out by the CONSERVE WILDLIFE FOUNDATION OF NEW JERSEY HERE.

FERAL PEACOCKS: SOMETHING COMPLETELY “DIFFERENT (OF ABACO)”

June 15, 2015 by Rolling Harbour

FERAL PEACOCKS: SOMETHING COMPLETELY “DIFFERENT (OF ABACO)”

Driving the Highway south from Marsh Harbour, past the turn-off to Winding Bay and Cherokee, you reach an unassuming side road. This takes you to Casuarina, its gorgeous beach and the canal cut that leads to Cherokee Sound and … bonefish. At the junction you can hardly fail to see the large, time-worn notice for “Different of Abaco“, the former fishing lodge owned by Nettica Symonette. It has been defunct for many years. The lodge buildings are sadly dilapidated and *safety alert* the wooden boards are frail. The grounds are romantically overgrown, and dotted with half-concealed derelict vehicles and machinery rusting away benignly as the seasons pass. The large ponds that must have once been attractive are brackish and uninviting. But guess what! The place is a haven for birds.

The most surprising sight is of peafowl – the collective name for peacocks, peahens and peachicks. This flamboyant species was introduced many years ago as a decorative addition to the Lodge and its grounds. It was part of a wider, more ambitious scheme to reintroduce a breeding flock of flamingoes to Abaco. These had regrettably become extirpated from the island and then, as now, were only found as vagrant individuals. The attempt sadly failed and the flamingoes disappeared. Rumours sometimes surface of breeding pairs far out on the Marls or in a secluded place in the far south of the island, but these remain unsubstantiated. The peafowl introduction, however, has proved to be an unexpected success.

Peacocks swaggering in the grounds: note the fully feathered tails (cf photo #2 above) Peacock, Abaco (Nina Henry) 3

The compilation of “THE BIRDS OF ABACO” involved plenty of decision-making. We obviously couldn’t feature every recorded species – for a start, for many species there were merely reports of sightings but no (or only inadequate) photographs. One interesting factor for consideration was the stage at which an introduced species becomes bird OF Abaco as opposed to a non-indigenous bird that happens to be IN Abaco.

Rhonda Pearce’s Peafowl Gallery (NB peachicks included!) above demonstrates why this species was an easy choice for inclusion. On the assumption that the original birds were brought to the Lodge in the late ’80s or early ’90s, the chicks you see here must be several generations down the line. A breeding population has been established in the wild, as the grounds of D of A have become. The evidence is that it is spreading slowly – across the road, further into the settlement at Casuarina and recently even further afield.

Celia Rogers photographed this cluster of peahens in Casuarina – but the two males were on the road to Cherokee, maybe 3 or 4 miles distance to the north as the peacock struts

So that’s how the feral peacocks of Abaco come to be classified (in a purely unofficial way) as birds OF Abaco for the purposes of the book**. Once they would have been viewed as pets – like the muscovy ducks that can be found in a few places, Gilpin Point for example. But in the wilderness that Different of Abaco has become for many years, the descendants of the original peacocks are breeding contentedly, expanding their population, and are wholly unreliant on human intervention. Verily feral, in fact.

**That, and the fact that Mrs RH borrowed my camera and undeniably took the best photos of the male and female birds (#1 and #4 above), as seen on pp 70-71 of the book…

KILLDEER ON ABACO? IT DOESN’T, BUT ACE NAME ANYWAY

June 11, 2015 by Rolling Harbour

KILLDEER ON ABACO? IT DOESN’T, BUT ACE NAME ANYWAY

The KILLDEER Charadrius vociferus is a fairly common winter resident plover on Abaco. They can often be found on the Delphi beach, and the lovely beach at Casuarina is another place to spot them. They can easily be distinguished from other plover species, being the only ones with two black frontal bands – see above and below. The lower picture, you’ll be relieved to hear, is not the fabled ‘legless killdeer’, but is simply having a little rest on a nice warm wall.

The killdeer’s name is a bit of a puzzle, frankly. The Latin term Charadrius vociferus basically means “shouty plover”, but it’s a long way from that to “killdeer”. This is another one of those bird names that are allegedly onomatopoeic – and thankfully it has nothing whatsoever to do with savage behaviour involving Bambi and his ilk (or elk, even). Supposedly the killdeer call is “Kill…Deer”, in the same way as the bobwhite calls an interrogative “Bob…White?”.

Consulting some random authorities reveals divergence of opinion on the issue, with definite bet-hedging between ‘kill-dee’ variations and ‘dee dee dees’. Except for Messrs Flieg & Sanders who opine (rudely) ‘the shrill, loud, monotonous call resembles its name’. Yet while I completely get the ‘Bob…White?’ thing, I’m not so sure with the killdeer. Were I a little killdeer, it’s a name I’d like to have anyway. Respect! But what do these sound like to you?

I’ve mentioned the distinctive double black breast-bands that distinguish the killdeer from its brother plovers. These can be seen at quite a distance, as this shot on the Delphi beach by Mrs RH shows (the tracks are from Smithy’s seaweed-clearing tractor).

The babies are, like all plover chicks, totes irresistibz munchkins

And like other plovers, a killdeer will defend its nest and young with a broken wing display to distract predators, lurching pathetically across the sand, moving ever further away from the nest.

I think we can safely conclude that, while the bird doesn’t quite live up to the cervidae-cidal tendencies suggested by its name, nor even sound particularly as though it is saying “killdeer”, it is a very attractive plover to have around whatever the heck its call may resemble.

NORTHERN PINTAILS ON ABACO: LOOKING SHARP

June 5, 2015 by Rolling Harbour

NORTHERN PINTAILS ON ABACO: LOOKING SHARP

The Northern Pintail Anas acuta is a relatively rare winter resident dabbling duck on Abaco. The species has a huge range, being found throughout much of the northern hemisphere.

DABBLING DUCKS – PINTAILS UP

The ‘acuta’ in the Latin name refers to the characteristic sharp ‘pin tail’. As so often, the drake is a somewhat flashy specimen while the female is unassuming or, as some sources harshly put it, dull and drab. And while the drake makes a melodious whistle, the female simply quacks or croaks.

FLASHY MALE

DULL & DRAB FEMALE? DEBATABLE!

Northern Pintails form flocks and are happy to mix with other species. Their long necks give the edge over similarly-sized dabbling ducks such as the mallard, enabling them to reach deeper down in the water to feed.

THREATS TO THE SPECIES

Predation of nests and chicks by animals and birds such as birds of prey and (some) gulls
Parasites including worms and lice, to which they seem to be susceptible; and avian diseases including bird ‘flu
Hunting: they are a good target species being swift and agile in the air (for sport) yet quite large (for success rate). Also, delicious (for dinner).
Lead poisoning from shot or angling tackle, research has shown. A major problem with all bottom-feeders, though improved where laws prohibiting lead shot have been introduced
Loss of wetland areas to agriculture or due to habitat or climate changes

On Abaco, Northern Pintails arrive in the autumn and leave as spring approaches. They are most likely to be found on ponds such as the one at Treasure Cay Golf Course, where I photographed the male; and at Gilpin Point where I spotted the lone female (at a distance). Below are both genders together for comparison (NB not taken on Abaco).

BREEDING TIME

Mating is aquatic, by the usual anatine method in which the female lowers herself in the water to indicate her agreement to the proposal whereupon the male tries to drown her. Apparently after mating, the male raises his head and whistles – whether as a signal that it’s all over or exaltation or relief has not been researched. Yet.

“THEY CALL ME THE HUNTER…” A GREEN HERON ON ABACO

May 29, 2015 by Rolling Harbour

“THEY CALL ME THE HUNTER…” A GREEN HERON ON ABACO

There are a number of birding hotspots on South Abaco (defined loosely for avian purposes as south from Marsh Harbour). Most are attractive places to be; a few (e.g. the town dump) less so, requiring additional skills to avoid taking your long-awaited ‘life bird’ in a pool of grossness…

Always a good bet, Gilpin Point near Crossing Rocks is definitely worth a visit at almost any time, especially the brackish pond just inland from the shoreline. Bear in mind it is (a) a longish private road (we got a puncture down there once…*) and (b) it is private land. However Perry Maillis is always welcoming to tidy birders who bring only enthusiasm and take only pictures. Plus he very kindly changed our wheel! At the end of this post is a rough list of birds I have seen at Gilpin, with one or two that I know have also been seen there (photographic evidence!)

*I realise I should say we got a ‘flat’, but to me that would mean we had obtained an apartment. We are indeed “nations divided by a common language” (Attrib variously to Wilde, Shaw & Churchill)

We found this small Green Heron quite easily. We’d watched it fly onto a stump in the pond near the jetty, then fly closer to the shoreline. By tiptoeing onto the jetty, we could see it perched close to the water, inspecting it with a fierce and predatory eye. Both eyes, in fact.

The hunting technique is deceptively simple. Note the long sharp stabbing beak. Note the large feet and claws for gripping securely Here’s how it is done. As a fish is sighted, so the heron leans forward, beak closer to the water, more streamlined to look at.

As the prey unwittingly approaches the bird slowly tilts further forward unless its beak almost touches the water, the quicker to strike…

The actual strike is so rapid that it is barely possible to see with the naked eye, let alone to photograph it clearly. For me and my little Pentax, anyway. But the end result is rarely in doubt, with a small fish struggling but securely held. It will be down the heron’s gullet in a matter of seconds.

I left the heron as it settled slowly back into ‘scanning the water mode’ while I went to look at some Lesser Yellowlegs nearby

I returned a few minutes later. Scanning was still in progress, and the bird started the gradual ‘leaning forward’ process as it sighted a fish

Get ready to spearfish…

Epic success for the heron, epic fail for the photographer… Green Heron, Gilpin Point, Abaco (Keith Salvesen)09

“Ha ha Mr Human with your funny black clicky thing hanging round the thing that attaches your head to your body. I was too quick for you. Who hasn’t got the hang of shutter speed yet? Eh? I win the fish. I win the game…”

ROUGH GILPIN CHECKLIST

Species we have found on and around the pond include Black-necked Stilts, Little Blue Heron, Great Blue Heron, Tri-colored Heron, Snowy Egret, Reddish Egret, Yellow-crowned Night Heron, Sora, hordes of White-cheeked Pintails, Northern Pintails, Lesser Yellowlegs, Belted Kingfisher, Turkey Vulture, Smooth-billed Ani, American Kestrel, Bahama Woodstar, Cuban Emerald, Mucovy Duck (pets!) and – for the first time this year – Green heron. As a bonus, Gilpin has become a regular stop for flocks of Abaco Parrots. Other species found there include American Flamingo, Brown Pelican, DC Cormorants and Limpkin. I’ve no doubt there are shorebirds on the beach such as Wilson’s Plovers, various gulls to be identified, and passing tropicbirds & magnificent frigatebirds high over the water.

VOLUNTARY MUSICAL DIGRESSION

‘The Hunter’ is a well-known Albert King / Stax song from 1967 with elements reminiscent of many blues songs and lyrics before that. The best known versions are probably the one by Free (‘Tons of Sobs’ 1968), which is un-improvable and definitive; and the doff of the cap by Led Zeppelin towards the end of ‘How Many More Times’… However ‘Pacific Gas and Electric’ made a pretty good stab at the song, also in the late ’60s

CARIBBEAN ENDEMIC BIRD FESTIVAL: NASSAU BIRDERS VISIT ABACO

CARIBBEAN ENDEMIC BIRD FESTIVAL: NASSAU BIRDERS VISIT ABACO

THE CARIBBEAN ENDEMIC BIRD FESTIVAL (CEBF) is a Caribbean-wide festival that aims to heighten awareness for birds generally in the region. It is sponsored by the excellent BIRDS CARIBBEAN organisation – click the link to see what it is all about. Birds, obviously, but from the points of view both of promoting and of preserving the rich avian variety throughout the Caribbean.

As part of the CEBF celebrations this month, a birding group from New Providence came to Abaco to explore the birdlife. The expedition group included several well-known local bird experts, all the better for locating and identifying species and ensuring a comprehensive checklist could be compiled. Also in the group was photographer Linda Huber, whose photos you will undoubtedly have seen in Bahamas publications, including the recently published small guide BEAUTIFUL BAHAMA BIRDS (click to see my review and further details – highly recommended for any birder from novice up). Here are a few of Linda’s photos of some of the birds seen during the expedition, a gallery that shows the extraordinary diversity of species to found in a short time on Abaco.

Apologies to those who received a ‘false start’ draft of this post. It was lunchtime, I was hungry, I pressed ‘Save Draft’… or thought I had. Why is the ‘Publish’ button so close? Oh. Right. I see. It’s not its fault, it’s mine…

The WEST-INDIAN WOODPECKER, now found only on Abaco and (rarely) San Salvador
2 or 3 introduced or domestic species (if that Muscovy Duck was at Gilpin Point it’s a pet!)
The debatable ‘Caribbean Coot’, about which it has been written** The American Coot is familiar to all, but controversy surrounds the Caribbean Coot with its all-white frontal shield. Some authorities say it is a separate species; others say it is a true subspecies of the American Coot; some claim it is simply a local variant. Bond (1947) treats them as distinct species. The image below shows the two species together. They coexist contentedly and are indifferent to the debate.

“STRIKE THE POSE”: BLUE-GRAY GNATCATCHERS ON ABACO

“STRIKE THE POSE”: BLUE-GRAY GNATCATCHERS ON ABACO

I’ve featured these little birds before, including a few I took a couple of months back. For reasons to do with a current project I have been revisiting some of my archive folders of Abaco birds. Most are carefully and correctly labelled, which in most cases is easy – ‘Abaco Parrots’; ‘W Spindalis’; B/quits’ etc. Some have more fancy shortcut names that I’m just getting into – ‘PIPL’; ‘BAWA’; ‘WESA’ and so on. And some are crammed into generic folders like ‘Shorebirds Misc’, ‘Gulls Terns Whatever’ or ‘Warblers???’ pending further attention (if ever).

The BGGs I have previously shown have all been photographed on South Abaco. Several of the photos here were taken in and around the Treasure Cay area by Becky Marvil, one of the photographic contributors to THE BIRDS OF ABACO. It’s good to remember that although South Abaco provides the best birding, there are other parts of the island, and some Cays such as Man-o-War, where the birding is also very good.

BGGs are well-known for their irreziztbz little ways – coming to check you out if you pish, click or whistle softly in thick coppice; posing daintily for the camera; and maybe even preceding or following you down a track in a companionable way. They may be small, but they always a welcome sight and they make for a very attractive bird gallery.

YELLOW WARBLERS ON ABACO

May 18, 2015 by Rolling Harbour

YELLOW WARBLERS ON ABACO

Of the 37 WARBLER SPECIES recorded for Abaco, 25 are mainly or partly yellow. So talk of a ‘yellow warbler’ can as easily be a general description matching any one of a number of species, as a particular description of the one and only Yellow Warbler Setophaga petechia. This small sunny bird is a common permanent resident on Abaco, one of only 5 resident warblers. The other 4 don’t help the situation much, by dint of all being yellow to a greater or lesser extent.

My general rule of thumb is that the Yellow Warbler out-yellows all the rest (though the winter-resident PROTHONOTARY gives it a run for its money), with the adult males bright and cheerful all over and the females rather less glaring but still demonstrably yellow from beak to tail tip.

Q. ARE THEY ALWAYS EASY TO SEE? A. SEE BELOW, GO FIGURE

Q. CAN YOU SHOW MORE PRETTY FEMALES? A. BY ALL MEANS

Q. SO YEWAs ARE COMMON? HAVE YOU EVER PHOTOGRAPHED ONE? A. ONLY HOPELESSLY

Q. DO THEY HAVE AN ATTITUDE PROBLEM? A. ONLY VERY RARELY

A THREAT TO THE SPECIES Shiny Cowbirds, luckily still rare on Abaco, favour yellow warbler nests for their parasitic egg-laying, with sadly predictable results. These cowbirds properly belong in South America, but they are gradually spreading north through the Caribbean, and have now reached Florida. I’m beginning to take a (purely personal) hard line on invasive species where they diminish and destroy indigenous species: eradication. The feral peacocks of Casuarina, now several generations down the line from their original introduction as exotic pets, do no harm and are undeniably decorative. But would you prefer the pretty yellow warbler and its fledglings in your garden, or the shiny cowbird that displaced them?

And finally… the song that out-yellows all other songs with the word ‘yellow’ in the title – it is the only song called just that one word!

ENDANGERED SPECIES DAY: ONE LITTLE REASON WHY IT MATTERS…

May 15, 2015 by Rolling Harbour

I had been going to post a selection of bird photos to mark Endangered Species Day today. I’d begun to plan the details – the birds to use, the captions for each and so on. Then I saw one photograph that is so charming and yet so poignant that I realised that adding further images would be superfluous. This tiny piping plover chick is a potent symbol of the vulnerability of all threatened species.

This shot was taken by award-winning and renowned wildlife photographer Melissa Groo. If you want to see the most wonderful and varied wildlife photography that you could ever imagine, please go to Melissa’s website and prepare to be amazed. You will find it HERE.

I have posted several times about the endangered piping plovers, many of which overwinter in the northern Bahamas generally, Abaco particularly, and the Delphi Club beach specifically. There are believed to be fewer than 8000 individual birds on earth, and their little world of the shoreline is threatened at both ends of their migration, as well as at their rest ‘stopovers’ en route in either direction. Conservation programs at each end of the range are proving effective at preserving the plovers’ habitat, and the population does seem to have increased slightly. Each chick protected represents a small triumph for conservation.

PIONEER NATURALISTS & ABACO BIRDS: POTTED BIOGRAPHIES

May 8, 2015 by Rolling Harbour

Wilson’s Plover, Abaco (Craig Nash)

PIONEER NATURALISTS & ABACO BIRDS: POTTED BIOGRAPHIES

Who were all the people – all men, I’m afraid – who are immortalised in the names of birds they first discovered or recorded or collected specimens of or wrote about? In various previous birds posts I have given brief bios of the naturalist for whom the particular species under consideration is named. I’ve decided to bring all those who specifically relate to Abaco together in one place. There is not (as far as I know) a collective term for ornithologists, so may I introduce a “Scope” or “Twitch” of them…

ALEXANDER WILSON 1766 – 1813

Mr Wilson Wilson’s phalarope, plover, snipe, storm-petrel, warbler

Alexander Wilson was a scottish poet and writer. He specialised in ballads, pastoral pieces, and satirical commentary on the conditions of weavers in the mills. The latter got him into trouble when he overstepped the mark by making a vicious written attack on one mill owner. He was arrested, convicted and sentenced to burn the work in public (fair enough, perhaps) and imprisoned (somewhat harsh). After his release, he sensibly emigrated to America in 1794.

Wilson became a teacher in Pennsylvania, and develpoped his interests in ornithology and painting. His ambitious plan was to publish a collection of illustrations of all the birds of North America. He travelled widely, collecting, painting, and securing subscriptions to fund a nine-volume American Ornithology (1808–1814). Of the 268 species of birds illustrated, 26 had never previously been described. Wilson died during the preparation of the ninth volume, which was completed and published by George Ord. Wilson predated John James Audubon (though not by many years) and is generally acknowledged to be the founder of American ornithol0gy.

For examples of Wilson’s American Birds, check out the excellent Virginia University records HERE

Wilson’s Phalarope (Craig Nash)

CHARLES LUCIEN BONAPARTE 1803 – 1853

Bonaparte’s gull, Zenaida dove

Charles Lucien Bonaparte, 2nd Prince of Canino and Musignano was a French biologist and ornithologist. He was nephew of the Emperor Napoleon. He married his cousin Zenaïde, by whom he had twelve children. They moved from Italy to Philadelphia, by which time Bonaparte had already developed a keen interest in ornithology. He collected specimens of a new storm-petrel, later named after the Scottish ornithologist Alexander Wilson (see above).

Bonaparte studied the ornithology of the United States, and updated Wilson’s American Ornithology. His revised edition was published between 1825 and 1833. He was a keen supporter of a (then unknown) ornithologist John James Audubon. Rather sweetly, he created the genus Zenaida, after his wife, applying it to the White-winged Dove Zenaida asiatica, Zenaida Dove Zenaida aurita and Mourning Dove Zenaida macroura. He himself was later honoured in the name ‘Bonaparte’s Gull’.

Bonaparte’s Gull, Abaco (Bruce Hallett)

RAMON LA SAGRA (1798 -1871)

Mr La Sagra La Sagra’s Flycatcher

Ramón Dionisio José de la Sagra y Peris was a multi-talented man, being a Spanish botanist and also a writer, economist, sociologist, politician, anarchist, and founder of the world’s first anarchist journal El Porvenir (“The Future”). He lived in Cuba and became director of Havana’s Botanical Garden; his name lives on arguably more significantly in ornithological than in anarchist circles (actually, an ‘anarchist circle’ must surely be a contradiction in terms…)

La Sagra’s Flycatcher, Abaco (Keith Salvesen)

A Cuban stamp commemorates the death of Juan Gundlach, the nauralist who chose La Sagra’s name to bestow on the flycatcher, and who himself is honoured in the name of the Bahama Mockingbird Mimus gundlachii

WILLIAM JOHN SWAINSON (1789 – 1855)

Mr Swainson For Abaco: Swainson’s Hawk, Thrush & Warbler

Swainson was an English ornithologist, entomologist, conchologist, natural historian, and a gifted illustrator of the natural world. He was a pioneer of the new lithographic technology, which enabled quicker reproduction of his work than engraving. Swainson lent his name to a number of avian species, three of which may be found on Abaco – the Swainson’s Hawk, Thrush and Warbler. The hawk is a rare visitor; the thrush is a transient, passing through the Bahamas during migration; and the warbler is a hard-to-find winter resident. Below is the only known Swainson’s Hawk to be photographed on Abaco.

JOHN ISIAH NORTHROP (1861 – 91)

640px-Picture_of_John_Isaiah_Northrop Bahama Oriole (Icterus northropi)

John Isiah Northrop, for whom the endemic BAHAMA ORIOLE Icterus northropi is named, entailed a bit more research. The link above will take you to my post about this very beautiful species that is sadly on the brink of extinction. Until recently it was found only on Abaco and Andros, but is now extirpated from Abaco and exists only in certain enclaves on Andros.

Bahamas Oriole, Andros (Binkie Van Es)

I can do no better than regurgitate the info provided by the University of Glasgow Library Research Annexe in relation to a fine illustration from A Naturalist in the Bahamas (1910), reprinted in The Auk journal (below) at a time when Icterus northropi was still a mere subspecies:

“The yellow and black Bahama Oriole (Icterus Northropi) is a bird species unique to the Bahamas. The bird was named for American ornithologist and zoologist, John Isiah Northrop (1861–91); the illustration comes from an account of the trip Northrop and his botanist wife, Alice, took to the Bahamas in 1889 which was published in his memory: A Naturalist in the Bahamas: John I. Northrop, October 12 1861-June 25, 1891; a memorial volume (Columbia University Press, 1910). It was edited and introduced by Henry Fairfield Osborn, professor of zoology at Columbia University where Northrop worked as a tutor and was killed in a laboratory explosion shortly (9 days) before the birth of his son John Howard Northrop (who became a Nobel prize-winning chemist)”.

JARED POTTER KIRTLAND 1793 –1877

260px-Jared_Potter_Kirtland_1793-1877 Kirtland’s Warbler (Setophaga kirtlandii)

Jared Potter Kirtland was a naturalist, malacologist and politician, most active in Ohio where he served as a probate judge, and in the Ohio House of Representatives. He was also a physician and co-founder of a University Medical School. Kirtland became one of America’s leading naturalists, with a particular interest in horticulture and sea shells. He published numerous natural history articles, and was a founder and president of the Kirtland Society of Natural History and the Cleveland Academy of Natural Science.

Somewhere in amongst all this, he discovered or at least studied the warbler that was named after him. This rare bird is found in small numbers only in certain areas of Michigan; and overwinters in the Bahamas including on Abaco. They a very hard to find, and harder still to photograph. This year we made an expedition into remote backcountry and found 4, more of which another time…

Kirtland’s Warbler, Abaco (Woody Bracey)

JOHN JAMES AUDUBON (1785 – 1851)

John James Audubon never went to Abaco. The nearest he got was probably in 1820, when he made a field trip to the southern states, including Florida; or in the 1830s when he made at least one trip to Key West. One technique that set him apart from contemporaries was his method of producing naturalistic (as opposed to ‘stuffed bird’) drawings. It involved killing birds using very fine shot, and then using wires to pose them naturally, according to his field sketches. This contrasted with the usual technique of using a stuffed specimen as a model.

Although no Abaco birds are specifically named for Audubon, it is almost impossible to dip a toe into ornithological history without immediately stubbing it on Audubon’s name. Hence his inclusion in this piece, bringing it to a conclusion.

Audubon’s master-work was his renowned Birds of America, arguably the most famous bird tome ever. There are about 120 sets of the original book still in existence. They were incredibly expensive to produce in contemporary terms; and in modern times a set sold for $11.5 million at Sotheby’s London in 2010, setting the unbeaten record for the world’s most expensive book sale. Recently there was great excitement over the sale of another set at Christie’s New York, but the sale price was far lower, a mere $7,922,500…

PLOVER LOVER? MEET SOME CUTE CHICKS ON ABACO

PLOVER LOVER? MEET SOME CUTE CHICKS ON ABACO

(*Serious Voice*) “The Wilson’s Plover is the only permanent resident plover found on Abaco, the other species being the winter resident Black-bellied Plover, Semipalmated Plover, Piping Plover and Killdeer; and the rare transient American Golden Plover. The nidification of the Wilson’s Plover is by common consent among naturalists the most…”

But let’s not get carried away with all that pompous ornithological stuff. There are baby plovers to be considered. Each one exudz adorbz and absorbz admirz. Most of the photos below were taken on the beach at Delphi. Ready? Let’s meet some chicks… But you can’t have them without first having the eggs, can you?

The Wilson’s Plovers at Delphi generally nest at the north end of the beach, up towards the reef. It is secluded, has good sight-lines and is bordered by pines. On the approach of a predator or human (in this case, me), the tiny chicks are sent scuttling to safety at the back of the beach while the parents prepare to tough it out if need be…

“You ain’t seen me, right?”

“I know we are caught in the open, but if we stand really still, you can’t see us, right?”

One of the most fascinating aspects of bird behaviour to watch is the so-called ‘broken-wing’ display put on by plover parent(s) to distract a predator away from a nest or scrape, and the eggs or chicks in it. Kildeer and black-necked stilts are among other species that do this performance. It goes like something like this:

“Oh! OW! I am helpless. Please don’t attack me, Apex Predator, for I am but a vulnerable plover…”

“But kindly follow me as I flap pathetically (moving away from my nest). I can’t fly, you know…”

Camouflage also plays a part in the protection of these little creatures. This chick is on the rocks at the north end of the Delphi beach, the bit where you begin to wish you’d worn shoes because the rock is so sharp… From 10 feet away, you might well miss seeing the chick completely.

This is one of my favourite shots, also at Delphi, taken by Sandy Walker

Quite a while ago, I wrote about a Wilson’s Plover family that had made their scrape at Nettie’s Point, the place where the bonefishing skiffs are launched. They chose their homemaking site right where the trucks and trailers turn. Big mistake you might think. But the kind guides built a small stockade of branches round the scrape so that it could clearly be seen and avoided. After that, Mrs WP settled down happily and Mr WP stood guard whenever anyone was around…

The protective stockade in place. Mrs Plover in place. All’s well with the world
