Last year held hopes of a joyous reunion – and indeed union – in Abaco waters between young manatees Randy and Georgie. He had taken the trip from the Berry Is., around the top of Abaco and down the east coast as far at Little Harbour. She lives in Cherokee. Tantalisingly close. But then Randy retraced his steps as far as Gorda Cay and hopes for the production of Abaco’s first manatee calf (at least, in living / recorded memory) turned to seagrass mulch. The poignant story and some great manatee close-up photos (including a ‘selfie’ of sorts on a Go-Pro) can be foundHERE
But manatees do breed elsewhere in the Bahamas, in particular the Berry Is. They also seem to favour the north end of Eleuthera, and have been seen on Andros and NP. True, the absence of significant freshwater sources in the Bahamas – an essential part of their diet – doesn’t make for an ideal habitat, but manatees do pair off and Bahamas calves are born. In summer 2012, there were four resident West Indian Manatees (Trichechus manatus) living in Great Harbour Cay, Berry Is. The adult female, Gina, had been there for 3 years – she originated from Florida. She had reportedly had 3 or 4 calves and was caring for her latest, a female calf called JJ, born in the late winter of 2011.
Adult female manatees are sexually mature at 6-10 years of age and have a gestation period of up to 13 months. The first two years of a calf’s life is spent with its mother. During this time they are taught where to find food, fresh water, warmth and shelter. Generally, after two years the calf is weaned and separates from its mother (see header image of Gina and JJ during that process)
Nursing a growing JJ
Now there is more good news for Gina, who has been under regular observation by the BMMRO. At the turn of the year, Gina was re-tagged in Harbour Island, Eleuthera. As reported, “she looks well, was very calm and is very pregnant… If the tag comes off and is found, please call the number on the tag to let us know – we are now monitoring her movements via the internet”.
Gina’s shows her best side
Coming atcher…
Tell-tale signs (to experts, anyway) of advanced pregnancy
I will post any further news about Gina as it arises. Meanwhile, for more information about West Indian manatees, you can visit the MANATEE PAGE. There are several links there to specific manatee stories, especially about Rita and her adventurous daughter GEORGIE, Abaco’s current favourite (indeed, only) resident manatee… Both Links need an update, I notice – they don’t cover Georgie’s subsequent return to Abaco and her contented settling down again in Cherokee where she seems happy as a… sirenian.

Merlins (Falco columbarius) are fierce small falcons that are fast and agile in flight. On Abaco, they are fairly common winter residents – though finding one and managing to photograph it may take a bit of doing. And maybe a dose of luck. The ‘columbarius‘ part of their taxonomy reflects their colloquial name ‘Pigeon Hawk’. Merlins are found throughout much of the northern hemisphere. They are classified as a New World species and an Old World / Eurasian subspecies, F c aesalon. Some argue for two distinct species, the gene pools of the two versions apparently having parted company ten of thousands of years ago. The birds aren’t overly bothered by the debate.
Merlin World Range Map: yellow = summer, blue = winter
HOW DO MERLINS DIFFER FROM AMERICAN KESTRELS (AMKE)?
Slightly larger and notably heavier (thus having more speed and endurance in flight)
Different colouring, e.g. lacking the indicative reddish-browns of the AMKE
Distinctive tail-barring as against black ends to the tail feathers with a white fringe
Unlike the AMKE they don’t hover, but close in directly on the small birds that are the main prey, often flying very low to surprise the victim.
For comparison: Merlin in South Abaco, American kestrel at Sandy Point
SO JUST HOW FIERCE ARE MERLINS?
Formidable! If you are a small or even medium-sized bird, you need to keep your wits about you. Merlins are largely ‘omni-habitat’ within their range, which includes open country, shrubland, light forest, and grasslands. They are fast, agile and strong. They can fly high, at medium height or at ground level, and are expert in surprise attack and rapid pursuit of prey. If you are a large bird of prey – a red-tailed hawk, perhaps – they may attack you with ferocity. They may not actually be trying to nail you, but to get you out of their territory and their catchment area.
Most of a merlin’s prey is taken in flight, and their speciality is ‘tail-chasing’ terrified birds. Breeding pairs may hunt cooperatively, with one bird flushing prey from cover into the open for its mate to… well, you get the picture – they are clever too. They may even pursue birds that have been flushed out by another bird of prey in the vicinity.
MERLINS AND PHOTOGRAPHERS
This is a slightly fraught relationship, because Merlins do not always pose as one might wish. Sometimes they are hard to see, being fairly well camouflaged unless they choose to ‘go out on a limb’.
And sometimes they don’t play by the rules relating to light and focus, making a clear shot difficult
This photo (2017) was taken on Elbow Cay (north end) by Jan Purdy Hulme Metcalf. It’s the first merlin photo from one of the Cays that I have come across.
FALCONRY AND MEDIEVAL HISTORY
Dame Juliana Berners
Merlins were popular birds in medieval English falconry, and according to the 1486 Boke of Seynt Albans, the ‘Marlyon’ was considered the appropriate hunting bird for a lady. This book contained an essay on hunting attributed to Dame Juliana Berners, the prioress of a Priory near St Albans, who, game lady that she must have been, also contributed to one of the earliest treatises on fishing, ‘Fysshynge wyth an Angle‘ (hence, angling).
The Dame’s Manuscript
FURTHER HISTORICAL DIGRESSION (feel free to skip to final para)
While reading up further about Dame Juliana, I came across (wiki-tnx) a wonderful ranking for birds of prey matched to status that I hadn’t encountered before. Here’s the list, from Emperor to Knave / Servant. A Tercel was / is a male falcon, especially a Peregrine or Gyrfalcon. A Musket is a sparrowhawk.
The Boke of Seynt Albans also contains list of collective nouns for animals and birds, many familiar today such as “gaggle of geese”. There are also humorous collective nouns for different professions, such as a “diligence of messengers”, a “melody of harpers”, a “blast of hunters”, “a subtlety of sergeants”, and a “superfluity of nuns”…
Merlins are still trained for hunting smaller birds; and because of their speed and agility they are used in falconry displays. Despite changing habitat, and a perceptible dip in population from the use of pesticides now banned (such as DDT), the Merlin seems to be holding its own very well 5 centuries after the Boke was written.
AND FINALLY… AUDUBON’S HANDSOME MERLINS

Velma Knowles is a resident of Nassau but originates from Abaco, where her grandparents lived. She is a keen photographer and birder, and recently spent a few days ‘back home’ on Abaco, staying on Man-o-War Cay during that strange ‘Christmas to New Year’ period that people have begun to refer to uncomfortably as ‘Twixmas’. Which I guess goes well with ‘Winterval’, if that neologism to describe the festive season rocks your sleigh.
Obviously, Velma had her camera with her; and a bit of quality birding was built into her schedule. Man-o-War has been having a prolific winter season, birdwise, with plenty of interesting migratory species passing through or settling there till Spring. But who would be content with a random warbler from the North, when there are Abaco’s specialist birds to encounter. Many of the birds featured – all are permanent residents – were seen on Man-o-War; others on the main island, though not actually at Delphi. Every bird shown can readily be found at Delphi, except perhaps for the Royal Tern, hence a few mentions. Let’s see how Velma did during her brief visit. (Spoiler Alert: very well indeed!).
A first ‘get’ for anyone’s Abaco checklist, and hence the header image. Not available on the Cays, so a trip to the ‘mainland’ and the wild pine forest and coppice of South Abaco is called for (they don’t venture north of Marsh Harbour). Rescued from the brink of extinction by careful conservation measures, the newly regenerating population of these unique underground-nesting parrots is gradually spreading, making them easier to find. During the day, Bahamas Palm Shores is a likely spot, as are locations to the south, including Delphi and the area around Crossing Rocks down to Gilpin Point.
Abaco’s lovely endemic hummingbird, rather pushed around by the brash incomer Cuban Emerald and therefore tending to avoid them (though both can be found at Delphi). The MALE CUBAN EMERALD has a striking purple throat aka ‘gorget’; the female (below) encountered by Velma has a more delicate colouring.
Unlike the Woodstar, these pretty iridescent green hummers are not endemic yet are more frequently encountered. They fly and change direction with astonishing speed, and are feeder-keen! Your sugar-water feeder will also attract Bananquits (pointy curved beak for the little holes) and West Indian Woodpeckers (long tongue) – and possibly Woodstars.
Splendid and occasionally noisy birds that nest in boxes under the eaves at Delphi. They produce two families a year. Velma writes “It has been a long wait but I finally saw this lifer, the West Indian Woodpecker. This bird is only found in The Bahamas, Cuba and the Cayman Islands. Awesome call!”
Velma writes “One of my targeted birds, the Western Spindalis, formerly called the stripe-headed tanager. On the way from the airport we spotted him on the side-of-the-road. Now that’s island-birding!”
Velma writes“Such a beautiful call… the Thick-billed Vireo. We heard a number of these guys on our bird-walks. The Thick-billed Vireo is a Caribbean endemic, being restricted to The Bahamas, the Caymans, the Turks and Caicos, two islands off of Cuba and one off of Haiti (though it has been reported in Florida)”
The adult male’s striking colour patches are orange-red; the female’s are more yellow. They are greedy at the feeder and rank high up in the pecking order, where smaller birds defer to them. One local name for them is ‘Police Bird’: the adult male’s colouring matches that of a Bahamian Police Officer’s uniform.
SANDERLING ON ABACO: A PERFECT PEEP FOR THE NEW YEAR
Various matters have kept me from the Blogosphere over the last week, so this is the first post for 2015. And what gorgeous little birds to have to hand for it – the Sanderling Calidris alba, a small sandpiper or ‘stint’ that is a common and welcome winter sight on the shorelines of Abaco, as in many other parts of the world. Who can resist these little guys, the ‘wave chasers’ that work along the shoreline, rapidly following the surf as food is exposed on the tide. Sometimes they will actually run into the ripples of an incoming wave to snap up a morsel of food, before scuttling back up the beach. They have been likened to clockwork toys. Amusing and cheering little birds to watch, so here is a gallery of them to enjoy and to welcome in the new year.

This sandpiper was taken by the late Tony Hepburn on Abaco. It has been ringed in its summer breeding grounds, and feeds in wave-softened sand with the tidal foam still visible all around it.
This made me chortle… Sanderling Lonelyheart!

“ELEVENPIPERSPIPING“: CUTEPLOVERSFORCHRISTMAS…
A Gorgeous Gallery of Ringed / Tagged PIPL by Danny Sauvageau
The numbers, positions, colours and numbering of the rings and tags pinpoints the precise origins of each bird. Note that some birds are ringed both above and below the ‘knee’. These markers have no effect on the daily lives of the birds, but are massively helpful in migration research. Danny’s photos are taken at ‘resting points’ in Florida where the birds pause as they migrate south for winter, many to Abaco and other Bahamas islands. Some birds shown below come from Canada, others from along the Eastern Seaboard of North America.
This New Jersey conservation organisation is very closely involved with research into PIPL migration to their winter grounds. Two scientists, Todd Pover and Stephanie Egger, recently made their annual visit to Abaco to count the plovers and check for ID markers. At one remote location they found an amazing 88 birds. However, by the time they got to Delphi, the four Pipers that had been playing on the beach for a couple of weeks had moved off, unsettled by windy conditions.

PAINTED BUNTING
It’s hard to imagine a more Christmasy little bird than the Painted Bunting. Bright blue, red, green primary colours make for a spectacular small bird to grace any garden or feeder. The 2 birds above were featured in a detailed post on the species several months ago, with plenty of other great photos,HEREBut there are other bunting species and close relations on Abaco that haven’t yet had a look-in on these pages. A common factor is the little fat beak and a great liking for seeds…

The birds above are all buntings or part of the wider bunting family. The definition is somewhat flexible and includes piranga and tanager species (and in the past the Western Spindalis, formerly the Stripe-headed Tanager). All were photographed on Abaco, mostly at the Delphi Club or Bahama Palm Shores. The photos below are a flagrant cheat. You’ll never see one of these on Abaco. They were taken by me a couple of years back in Central Park, NYC, made magic with snow and freezing air. Have a very happy and colourful Christmas!

Well, with a bit of digging into the naming of this tern species, I have discovered that the ‘bridled’ part of it apparently refers to the white band / collar at the back of its neck. This is puzzling because one would expect a ‘bridle’ to start at the mouth / beak and angle backwards. Like a horse. Like the conspicuous black line from the base of this tern’s beak sweeping back past its eyes and joining its black cap at the back. How wrong that assumption would be…
Far more exciting than the ‘bridle’ question is the origin of the Bridled Tern’s species name, Onychoprion anaethetus. Wondering about the medical-sounding word, I discovered via the excellent ARKIVEthat the name derives from the Greek for ‘senseless’ or ‘stupid’, “a reference to the ease with which hungry sailors captured this bird“. So there you have it: not ‘aesthetically pleasing’ or similar compliment, but just plain dozy.
The Bridled Tern is a fairly common summer resident on Abaco, where it breeds. It is one of 12 tern species recorded on Abaco, the others being Sooty Tern, Least Tern, Gull-billed Tern, Caspian Tern, Black Tern, Roseate Tern, Common Tern, Arctic Tern, Forster’s Tern, Royal Ternand Sandwich Tern.
These terns plunge-dive for fish, but will also take them from the surface. Unlike other terns – for example the Least Tern – they usually dive directly and not from a hover. When courting, the male will rather charmingly woo the female by offering her fish.
I have briefly featured this fish before in the context of its extraordinary camouflage abilities; and also its interesting ocular arrangements. Time to give it another swim around, I think, with some additional photos that I have collected.
Bothus lunatus is the Atlantic / Caribbean version of a species also found in the Pacific and Indian oceans. Adults may grow up to 18 inches long. The species is a ‘lefteye’ flounder, with both eyes on its left (top) side & its right side underneath. However a baby flounder looks & swims like normal fish, with bilateral eyes. As it grows, the right eye gradually ‘moves’ round to the topside, and it becomes a flatfish.
A flounder’s eyes can move independently of each other. One may look forwards, the other backwards
‘NOW YOU SEE IT…’ CAMO-FISH
The Peacock Flounder has extraordinary colour-changing powers, and can rapidly vary its background colour to make it closely resemble that of its surroundings. This enables it camouflage itself as it lies on the seabed.It can change coloration completely in between two to eight seconds.
Four frames of the same fish taken a few minutes apart showing the ability of flounders to change colors to match the surroundings (Wiki)
Check out these imitative patterns in Bahamas waters…
There are two advantages to the ability to camouflage (‘cryptic coloration‘). One is obviously to avoid detection by predators. The other is to enable the flounder to ambush its meals. They feed primarily on small fishes, crabs and shrimps, lying concealed on the seabed and grabbing any unwary prey that ventures too close. They will even partially bury themselves in the sand, leaving just their eye-stalks keeping watch…
HOW CAN THEY POSSIBLY CHANGE COLOUR SO QUICKLY?
Scientists are still puzzling this out. In a conch shell, it seems the flounder can coordinate its amazing all-round vision with its hormones, instantly releasing certain pigments to its skin cells and suppressing other pigments to make the colour match. Not convinced? Then watch this short video and prepare to be impressed.
Fred Riger of Grand Bahama Scuba, who kindly keeps a benign eye on my reef fish posts (he’s the expert), adds a third excellent reason for coloration changes: sex… “the male peacock flounder can, and does greatly intensify his colors, presumably to declare territory and attract females to his person. When doing this the males will also signal with the left pectoral fin, sticking it straight up and waving it around.” Maybe that is what is going on in the photo below – intensified, non-camouflage colours, and a raised fin…

OVENBIRDS FOR CHRISTMAS ON ABACO (NB NOT ROAST TURKEY)
The Ovenbird (Seiurus aurocapilla) is a small winter-resident warbler with distinctive orange head feathers that can be raised into a crest. I’m guessing this accomplishment is mainly used in the breeding season as a way to impress and attract a mate. Maybe when alarmed or excited at other times as well. Right now, with Christmas only ’12 sleeps’ away, they have become a visible presence on Abaco and the Cays despite their shyness and a general tendency to shuffle around in the undergrowth looking for insects and small snails.
You may hardly be aware of these rather unassuming little birds, and as they rootle their way through the dead leaves under shrubs they can look quite dull. See one lit up by the morning sun, however, and you’ll see how pretty and richly marked they are.
The Ovenbird enjoys the taxonomic distinction of being the only bird of its genus in the warbler family Parulidae. It is a so-called ‘monotypic’ species. It was formerly lumped in with Waterthrushes, but was found to be genetically dissimilar so its new status was granted.
The ovenbird is so named because it builds a domed nest (“oven”) with a side-entrance, constructed from foliage and vegetation. They tend to nest on the ground, making them vulnerable to predation. The species name for the ovenbird, Seiurus aurocapilla, has nothing to do with the nest shape, though. It derives from both Greek and Latin, and loosely means ‘shaking tail, golden haired’. No, nothing to do with Miley Cyrus either. Leave it.
Here are some recent shots taken by Charmaine Albury on Man-o-War Cay, showing the orange crest very clearly.
My plan to include audio of the ovenbird’s song and call has been temporarily thwarted by a glitch, but I’ll add them here when I have overcome the problem.
Gauge the size of the bird against the pod it is standing on…
In this photo, you can see that the orange crest feathers are raised

THICK-BILLED VIREOS: ABACO’S ONLY PERMANENT RESIDENT VIREO
Hard to know why I haven’t got round to featuring these little vireos before. Unlike the other 7 vireo species found on Abaco seasonally or as transients, the Thick-billed Vireo Vireo crassirostris is an ever-present permanent resident of the coppice and scrub; and their unmistakeable repeating song can be heard almost everywhere. It was the first bird song I heard on Abaco, and therefore the TBV was the first bird I learned to ID. I’ve got quite a soft spot for them, really.
Although TBVs are very easy to hear and track to a general area of coppice, I find actually seeing the bird creating the noise quite hard – let alone getting a clear camera shot. They always seem to be lurking several feet further away, deeper in the foliage, than the sound suggests. I’ve had some fun making TBV song iPhone recordings along the Delphi drive, practising the technique. If you want to know more about recording and converting to MP3 CLICK HERE.
One of my favourite images, from Gerlinde Taurer: a ‘shouty’ bird. We used it for ‘BIRDS OF ABACO‘.
I also love this perky little guy with a great beady-eyed pose taken by Bruce Hallett
Here’s a clip of song, which I’m sure will be immediately familiar to Bahamians:
Paul Driver / Xeno Canto
The main signifiers for this species, which in combination distinguish the TBV from the other vireo species on Abaco, are:
Two white wing bars
Yellow patch – usually quite prominent – between eye and beak
Thick bill – which immediately rules it out of being one of the 37 warbler species on Abaco…
Text book TBV
There are marked colour variations in the species according to maturity, season and to an extent gender (though m & f are quite similar). Here’s one that is causing wing-bar confusion by only showing traces. It also has quite dark upper parts.
This is a very yellow TBVWhereas this one has rather anaemic colorationFinally, this pretty TBV is very delicately marked
MAKING A SPLASH: SPERM WHALES & MANATEES IN ABACO WATERS
After a quiet spell on the cetacean and sirenian front, there is exciting news to report. First, the BMMRO encountered two sperm whales just off Sandy Point. I don’t know how close to the shore they actually were, but it was very friendly of them to come so near to the BMMRO HQ.
When whales are sighted from the research vessel, one of the tasks is to collect feces. This job is often undertaken by interns, and is a good way to learn that serious research may well involve unattractive work… They practise with… er… coffee grounds and a net. For more on this important yet unappealing aspect of whale research, CLICKNICE TO SEE FAMILIAR FECES. Another essential part of any sighting is to take fluke photos to enable ID. Every whale has different and distinctive patterning to the fluke, including general wear and tear. As a photo archive is built up, the researchers are able to recognise a particular whale and cross-reference it with previous sightings.
The third task of a sighting is to record clicks made by an individual whale. This enables an estimate of the whale’s size to be made, and again a sound archive is gradually built up from which comparisons can be made.
A NEW MANATEE VISITS MARSH HABOUR
FRIENDS OF THE ENVIRONMENT has just reported the sighting of a new manatee at the head of Marsh Harbour harbour. I’m not aware of any other sightings in the last couple of days, but as they say, “Please keep your eyes out and drive carefully! ContactBahamas Marine Mammal Research Organizationwith any further sighting reports by calling 357-6666. You can also share photos with them on Facebook. Also, please do not feed the manatee. They are able to find their own food and anything else may make them unhealthy”.
This is Abaco’s third recent manatee. First there was GEORGIE, who as far as I know is still comfortably settled in the Cherokee area. Then RANDYarrived earlier this and got to within about a few miles of Georgie… High hopes of a meeting – and ‘friendship, maybe more’ – were dashed when Randy turned round and headed back to Castaway Cay. Let’s hope this newcomer stays around. I wonder what he – or she – will be named? My suggestion is Abby or Abi, which I think is unisex…
Just as with the whale flukes, the tail of a manatee is an important means of identification. The new manatee’s tail has its own distinctive edge pattern, which will enable its future recognition. Here is an image of Randy’s tail, with its unique notch.

The White-rumped Sandpiper Calidris fuscicollisis one of a number of sandpiper species found on Abaco. You can see a gallery HERE. Many of them are confusingly similar, and it is with a sense of relief that one picks out some particular feature on a bird that marks it out from the other species.
The white-rumped sandpiper has, for a start, a white patch that shows above the base of the tail, rather in the manner of theyellow-rumped warbler. It is the only sandpiper with such a feature, and it is conclusive of ID… if you actually see it. You’ll notice that in the header image and the one above, no such white patch is visible. So although it is undoubtedly there, the bird you happen to be looking at – perhaps at a distance – may not have arranged its position and feathers to assist you. Frankly, the birds in the WRS group below are not cooperating either, except the furthest (blurry) one.
You can’t see it on this bird either, as it forages in a pond, spreading concentric circles across the water
Nor with this one. In fact, I have looked at dozens of photos to find a clear shot of said white marking and found only one really good one… but hedged around by the thick thorny protection of copyright.
However all is not lost. There is another feature of this sandpiper species that is unique to it, at least on Abaco (it is found also in the Baird’s sandpiper, but you won’t see that bird on the island). The unusually long wings of the white-rumped sandpiper extend beyond its tail when it is on the ground. You can see this in the photos above. It is a feature that should be clearly visible as you watch a bird on the shore, even if it isn’t showing its white rump. Here’s a very helpful composite from the Crossley ID Guide (Eastern Birds). You can see the extended wing length in the birds in the foreground. And if you look at the birds in flight, you will see the white rump exposed.
Like all peeps, these birds make high-pitched weebling sounds, which I have seen described as ‘like a child’s squeaky toy’. Here’s a small flock make a characteristic noise.
Ian Cruickshank / Xeno Canto
You will often see a WRS mixed up in a group of other shorebirds, so the wing-length ID method will help pick it out. Also, it will be notably larger than some, for example semipalmated sandpipers.
NB They are not always found on the shore or in water

FEWER THAN 300 LEFT IN THE WORLD – AND ALL ON ANDROS
Having just posted about the endangered NASSAU GROUPER and its protection by the introduction of a 3-month closed season, it’s time to focus on a rare, beautiful and vulnerable bird, the Bahama Oriole (Icterus northropi). It is IUCN Red Listed as ‘Critically Endangered’. ENDEMIC to the Bahamas, this bird lived only on Abaco and Andros. Not any more. Now you’ll only find them on Andros, the species having been lost to Abaco in very recent memory. The 1990s, in fact. And on Andros, this lovely bird is now struggling against the threat of extinction and is found only in limited areas in very small numbers. The most optimistic population estimate I have found puts the total as fewer than 300 individuals… the consensus puts the likely total in the region of 250.
THE SPECIES
In 2010, the Greater Antillean Oriole Icterus dominicensis was separated by the AMERICAN ORNOTHOLOGISTS’ UNION into 4 species, one being the Bahama Oriole. As the BNT wryly put it, “New species are always a source of excitement… but in this case the intrigue is overshadowed by a sense of alarm and urgency”. For by then this new species ‘in its own right’ was limited to certain parts of Andros, in small and diminishing numbers. It had already vanished from some areas – especially in North Andros – were it had formerly been abundant. The best estimates suggested 250 individual birds.
WHEN & WHY DID THEY VANISH FROM ABACO?
This is a classic ‘riddle wrapped in a mystery inside an enigma’. Various sources I have looked at use a formula such as “…became extirpated from Abaco in the 1990s”, or “disappeared for unknown reasons in the 1990s”. I’ve found no clear clue as to the cause – nor even when the last sighting of an oriole on Abaco was made. I haven’t found a photo of one taken on Abaco, although to be fair the option of snapping everything with wings several times using a digital camera with a large chip didn’t exist then. In the next para a number of crucial factors in the more recent decline of the Andros population are given; but as far as I can determine, some at least did not apply in the 1990s, or certainly not to the same extent. Maybe it was a combination of a degree of habitat loss and the gradual decline of a small population that could not breed prolifically enough to sustain the future population **.
THE MAIN CAUSES OF THE CRITICAL DECLINE ON ANDROS
Lethal Yellowing Diseaseof the coconut palm, prime nesting habitat for the oriole. In some areas on Andros (e.g. Staniard Creek), the palm has been all but wiped out.
The arrival and spread of the Shiny CowbirdMolothrus bonariensis, abrood parasitethat lays its eggs in the nests of other bird species such as the yellow warbler, the black-whiskered vireo… and the oriole. The cowbird reached Andros in the mid-1990s. The first Abaco report that I have found is from 1999 (so presumably, as the oriole was already gone from the island by then, they were not a factor). The cowbird is a summer resident on Abaco, though still relatively uncommon; and its range continues to expand northwards. Some might argue that the cowbird should be discouraged from spreading on Abaco right now for the sake of the indigenous warbler and vireo populations – before it is too late.
Habitat loss / island development (although Birdlife International notes “…the planting of coconut palms in residential areas has allowed the species to spread into human settlements”). Other factors put forward include forestry work, forest fires, diseases, rodents and feral cats – problems that affect many other birds such as the Abaco parrot.The photo below is a pleasure to include in this post. It was taken earlier this year on Andros by Christopher Johnson of Nassau. And here’s the thing. He is 13, and an avid birder. I’m sure he likes his X-Box time, but he certainly knows plenty about birds too. He’s quick off the mark with offering IDs – correct ones – for birds online, and when he saw this bird he knew the significance of it and managed to get some good shots too. This is my favourite, the oriole ‘vocalising’. See below for its song. Here is Christopher’s brief but enthusiastic field report: “Awesome trip to Andros this past weekend! Was amazed to see the Bahama Oriole and its nest — feeling great”.

A GLIMMER OF HOPE?
In the same way that urgent conservation measures were put in place to halt and then reverse the critical decline of the Abaco parrot population, similar projects are in place for the Bahama Oriole on Andros. One proposal is to establish a ‘captive breeding’ program leading to reintroduction and reinforcement of the wild population. According to the American Bird Conservancy, this could even include reintroduction on Abaco… So perhaps in a decade or two, this fine bird will once again become firmly established as one of the birds of Abaco.As I said in my Nassau Grouper post, a country’s attitude can to a degree be gauged by the pride with which it features its wildlife and natural resources in its stamps (I used North Korea for adverse comparison). In 2009 The Bahamas Postal Service even issued a ‘Rare Birds’ set featuring the Bahama Oriole.. I rest my case.

WHO WAS THE EPONYMOUS MR NORTHROP?
The comprehensive answer is 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 (New York: 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).
RELATED MATERIAL
“Rediscovering the Bahama Oriole” Erik Gauger, author of the excellent Notes from the Road and photographic contributor to the Birds of Abaco has a good tale of the pursuit of the apparent sighting of a Bahama Oriole on Abaco 2o years after its (supposed?) extirpation. You can read it HEREThe Auk Read more about this journal and the birding history of the BahamasHEREThere is a Care2Action ‘Save the Bahama Oriole Before It Is Too Late’ petition HERE. It seems to have stalled somewhat, so it would be good to generate some more signatories.** Mathematically inclined? Find out about the application of thestochastic processto the oriole’s situation. In a nutshell, this concerns the combined effect of several random adverse factors on sustainability, given that the oriole’s already very small population, very limited range and particular habitat requirements militate against breeding expansion, and therefore increase the likelihood of extinction. We can only hope this is not an inevitability…

NASSAU GROUPER: VULNERABLE, ENDANGERED… & NOW PROTECTED
The Nassau grouper Epinephelus striatus is one of a number of Caribbean grouper species found generally in the Northern Bahamas and specifically in Abaco waters. Others include the Black, Tiger, and Yellowfin groupers, the Red Hind,and the Graysby. The Nassau grouper is special, however, not least because (unlike the others) it is on theIUCN Red Listas an Endangered Species and is also a USNational Marine Fisheries ServiceSpecies of Concern. It is considered the most important of the groupers for commercial fishing in the Caribbean, and the IUCN listing data suggests that a population decline of 60% occurred over the last three generations (27-30 years), a startling rate. The current population size is estimated at >10,000 mature individuals.
The Nassau Grouper is a creature of the coral reefs in the Caribbean and adjacent seas, though it can also be found in deep water. It feeds in the daytime on small fish and small crustaceans such as shrimps, crabs and lobsters. It lurks in caves and recesses in the reef, sucking in the prey that passes unsuspecting by. The coloration of an individual fish may vary considerably with conditions, and it can adapt its colour to its surroundings as camouflage.
Tiger grouper meets Nassau grouper
Spawning takes place in December and January as the seawater cools, always at full moon, and always in the same place. In the moonlight, huge numbers of the grouper gather together to mate in a mass spawning aggregation. This may continue for several days. However, the species is slow breeder, which is why overfishing is particularly damaging to the population as the depleted stock cannot readily be replaced.
CONSERVATION ISSUES
There are other besides factors commercial overfishing that make the Nassau grouper so vulnerable, including fishing during the breeding season; taking undersized fish; pollution and reef decline; habitat loss; and invasive species. The spawning areas are especially vulnerable to exploitation. In the Bahamas, as elsewhere, the government has now instituted a closed fishing season for the Nassau grouper. Here is the BREEF flyer, just circulated – and in fact the reason for this post, which reminded me that I had planned to write about this fish!
Nassau grouper is eaten by barracudas, lizard fish, dolphins, sharks and other large predators of the reef community. But the predators that have the biggest impact on the grouper population are humans. People are fishing groupers before they can grow to maturity and reproduce. Sex change may also cause a problem. In undisturbed areas there are usually equal numbers of male and females. In heavily fished areas there are often three or more times more females than males. This means many eggs will not be fertilized during spawning. Other threats include, habitat destruction, coral breakage from divers, siltation from construction, runoff from logging and agriculture, dredging, sewage, oil spills and other contaminants that harm coral reefs where Nassau Groupers live.
There’s an extent to which a country can be judged on its attitude to wildlife from the stamps it chooses to issue. It’s something to do with appreciation and promotion of the country’s natural resources. For example, North Korea rates nil in this respect, with stamps involving scary weaponry, flags, marching and eerily glowing leaders – not a single sparrow to be seen. By fortunate contrast the Bahamas and itsPostal Service score very highly in celebrating the diversity of the wildlife of the islands.The Nassau Grouper was first featured on Bahamas stamps as long ago as 1971, some 25 years before the IUCN Red Listing, and probably before the sharp decline in population numbers had even begun.
In 2012 the Bahamas Postal Service released ‘a new definitive 16 stamp series’ depicting the marine life of The Bahamas. The Nassau has been promoted from 5c in 1971 to 70c in 2012. That’s inflation for you.
Finally in 2013 BREEF’s 20 years of marine conservation was commemorated with a distinguished and colourful set of 8 stamps, noting in their release:‘Two of the new stamps feature the Nassau Grouper, a now endangered species that has experienced severe population decline throughout the region… BREEF is well known as an advocate for an annual closed season for the iconic Nassau Grouper during its winter breeding period. The push for the closed season was based on scientific evidence of population collapses throughout the region due to overfishing. BREEF is calling on the government to implement a fixed closed season for the Nassau Grouper in order to protect the species and the fishing industry. The closed season traditionally runs during the spawning season from December 1st until February 28th, to allow the fish to reproduce. BREEF is calling urgently for the announcement of this year’s Nassau Grouper closed season….’ And so it came to pass… Not only is the Nassau grouper now worth 2 x 65c; it is strictly protected for 3 months during its breeding season. Maybe philately even had a hand in getting somewhere…

COMMON YELLOWTHROATS ON ABACO: CHEERFUL WINTER WARBLERS
Abaco is fortunate to be home to the endemic BAHAMA YELLOWTHROAT Geothlypis rostrata, a striking bird with a dashing black mask and bright yellow body in the male. You can see it with its fellow endemics HERE. But there is similar winter resident species, the COMMON YELLOWTHROAT Geothlypis trichas, that can be seen on Abaco between October and March. Now is a very good time to look out for them. However, the two species are easy to confuse.
Common Yellowthroat (male)
Bahama Yellowthroat (male)
WHAT’S THE DIFFERENCE?
SIZE – the BW is slightly larger and sturdier than the CW
BEAK – larger in the BW, and some might say it tends to be decurved
COLOUR – the BW is more colourful, with more extensive yellow underparts and mask
FEMALES – both species lack the mask and are duller; the female BW has a greyer head
HABITAT – both are found in the same areas; the CW prefers denser vegetation near water
DEBATEABLE – it seems to me the pale stripe behind the mask is usually less prominent in the BW
Common Yellowthroat male with conspicuous pale head-stripe
Both yellowthroat species are an endearing mix of shy and inquisitive. These birds are responsive to ‘pishing’, and once lured from cover they may remain nearby on low branches or shrubs watching you with interest as you watch them. Their song – similar in both species – is fairly easily imitated (or at least approximated), which may also bring them into the open – a source of great satisfaction to the amateur birder when it works. Unless it’s just coincidence, of course… The songs of the two species recorded below sound almost indistinguishable (except that the first one is professional and the second notably amateur…).

The third new bird species this year has been found on Abaco by bird authority Woody Bracey. After the excitement of 6BLACK-BELLIED WHISTLING DUCKSin June and aFORK-TAILED FLYCATCHER in October comes the very recent sighting (with photos) of a BROWN THRASHER, hitherto unrecorded for Abaco. It was seen near Treasure Cay, at the site of a derelict restaurant.
The Brown Thrasher (Toxostoma rufum) belongs to the same family that includes mockingbirds and the catbird – Mimidae. Its normal range includes Florida where it is resident, so there’s only 200 miles of ocean to cross to reach Abaco. Easier still with a stop-over on Grand Bahama. However I’ve checked for other Bahamas sightings, and so far I have found one recorded for Grand Bahama, and one for Eleuthera. So this first sighting on Abaco is possibly only the third for the Bahamas, suggesting that the Thrasher is generally not a great adventurer.
Here are some images in case you happen to see a strange brown speckled bird…
ADULT AND JUVENILE
And here are Woody’s evidential images of his sighting. They may not be such close shots as the others but they are conclusive for the record.
BESIDES ONE BIRD VISITING ABACO, WHAT’S INTERESTING ABOUT THE THRASHER?
They are known to have more than 1000 types of song, one of the largest bird repertoires
They repeat phrases 2 or 3 times before moving on to another (somewhat like Mockingbirds)
Rick Wigh / Xeno Canto
They are omnivorous, eating insects, snails, worms etc; and balancing that with fruit, seeds and nuts
They are shy birds, but can be very aggressive when defending territory or a nest site
They used their slightly decurved beaks to thrash around under leaves and ground debris as they forage – hence the name
YES INDEED, BUT IS THERE ONE REALLY MEMORABLE FACT ABOUT THEM?
OK. Their necks are extremely flexible and they have more vertebrae than camels or (get this!) giraffes.
AUDUBON’S DEPICTION OF A ‘FERRUGINOUS THRUSH’, AS IT WAS THEN KNOWN
The magnificent Osprey Pandion haliaetus is one of the world’s most successful raptors and can be found on every continent except Antarctica.
On Abaco the Osprey is a permanent breeding resident, and while certainly not an ‘every day bird’, the chances of seeing one are reasonable. They are fairly often seen flying over the bay at Delphi, or out on the Marls. A pair recently nested at Sandy Point close to Nancy’s restaurant.
There are few more exhilarating sights in the world of birds than an osprey swooping from a great height into the sea, emerging with a large fish held characteristically ‘fore and aft’ in its talons, and flying into the distance with heavy wing-beats. This wonderful close-up by wildlife photographerPHIL LANOUEshows an osprey that has actually managed to grab dinner for two…
This bird looks as if it is poised to dive onto some hapless fish
10 PANDION POINTS TO PONDER
Ospreys are also known as sea hawks, fish hawks or fish eagles. They are almost exclusively fish-eating
A mature adult’s wingspan may reach 6 feet
They are the only members of their taxonomic family, genus and species
Ospreys & owls are the only raptors with reversible outer toes to grasp prey firmly
They can carry fish weighing more than 4 lbs
They dive into water feet first to grab its prey; their nostrils can close up to keep out water
Osprey-watch.orgis a global site for mapping osprey nest locations / logging nesting observations
A New Jersey group has designed the optimum artificial nest platform, now an accepted standard
Ospreys usually mate for life
Osprey populations in many areas have been affected by pesticides and by egg trophy-hunters

The Osprey is a prolific symbol in national, cultural and sporting themes, and has been depicted on Bahamas stamps. And quite right too.

The latest version of the 40TH ANNIVERSARY OF THE BAHAMAS PROPOSAL FOR THE EXPANSION OF THE PROTECTED AREA SYSTEM OF THE COMMONWEALTH OF THE BAHAMAS has been published. It is a joint proposal by the Bahamas Government, The Nature Conservancy and the Bahamas National Trust. The breadth of the scheme is very ambitious, affecting all the principal Bahama Islands. To understand the objectives and scope of the project, you can see the whole 34-page project by clickingBAHAMAS PROPOSED PROTECTED AREAS 2014It is in pdf format, so you should be able to save it if you wish to.
Many people will be familiar with the proposals as they affect Abaco. However since the latest version appears to be a final draft, I thought it might be helpful to show the 4 proposed areas of protection and conservation in their present form. These are, in summary:
THE ABACO MARLS NATIONAL RESERVE A vast area of nearly 200,000 acres (300 square miles) of mangrove flats, sandbanks, creeks and wetland habitat
EAST ABACO CREEKS NATIONAL PARK13,000 acres (20 square miles) of wetland habitat that provides a vital wildlife nursery, and includes blue holes, creeks and a significant area for recreational activities (though Pete’s Pub at Little Harbour may be just outside the zone…)
CROSS HARBOUR PROTECTED AREA 14,000 acres (21 square miles) in South West Abaco, a crucial breeding area for a number of species,including bonefish
SOUTH ABACO BLUE HOLES CONSERVATION AREA A huge 34,000 acre (53 square miles) swathe of South Abaco to the west of the E D Highway, incorporating 4 inland blue holes and important cave systems, and 13 offshore blue holes. This is an area of mainly pine forest on land and low waters at sea, with an anticipated value for eco-tourism
Here are the BNT maps showing the extent of each area. Far more information will be found via the link to the report given above.

Published 2014 ~ 128pp ~ $20, available from the BNT
A fine new book on the birds of the Bahamas has recently been published by theBAHAMAS NATIONAL TRUSTandBIRDSCARIBBEAN. Compiled and edited by well-known Bahamas bird guideCAROLYN WARDLE with the BNT’s Lynn Gape and Predensa Moore, this slim book is packed with valuable information. It doesn’t set out to be an exhaustive field guide, a task already fully covered by Bruce Hallett’s indispensable Birds of the Bahamas and the TCI. Nor is it anything like my own photographic tome ‘Birds of Abaco’, differing in scope and intention, and weighing a mere 225 gms as opposed to 2 kilos! Beautiful Bahama Birds is eminently a book for the pocket, day bag or backback, to be carried along with your Hallett.
I have illustrated this review with photos of sample pages of the book, invariably the best way to give a clear impression of this kind of publication. Apologies that some of my images are a bit wonky, my copy being new and individual pages being hard to keep flat…
The photographs throughout the book are mainly the work of Linda Huber and the late Tony Hepburn. I was fortunate enough to be able to use some of Tony’s photographs for my own book, given with unreserved generosity; it is a fitting tribute to him that his images have now been published in Beautiful Bahama Birds, and that it is dedicated to him.
An idea of the broad scope and of the book and its usefulness to the birder can be gained from the contents pages, which I reproduce here. Click to enlarge them. The book is arranged in 3 parts: Let’s Go Birding; Field Guide to 60 Common Birds; and Conservation Now.
PART 1 offers plenty of useful information and practical advice about birding in general (I wish I could have read this before I started my own book!). Anyone who loves birds will benefit from this whole section, even if they would not call themselves a birder – especially Chapter 3 ‘Getting Closer to Bird Life’.
PART 2 All 5 Bahama endemics are featured in the main section, which is handily divided very broadly into ‘waterbirds’ and ‘land birds’. Some birds are commonly found on most islands; some have more limited range: for example the Bahama Oriole is now found only on Andros; and breeding populations of the Cuban Parrot are found only on Abaco and Inagua (the increasing number of sightings on New Providence give some hope for a breeding population there too). I’ve chosen the parrot because the underground-nesting subspecies on Abaco is so special; and the Flamingo and Bahama Oriole, both very sadly extirpated from Abaco in recent memory.
The illustrations by Tracy Pederson and Kristin Willams are clear and highlight well the identifiers for each species. Where necessary, species variations are shown, for example between sexes, breeding / non-breeding plumage and adult / immature. This can be a confusing and even fraught area (as I constantly find), which this book usefully addresses. Some birds in flight are also shown to aid ID.
PART 3 covers the National Parks, important birding areas of the Bahamas, conservation matters, and a charming section on birds in Bahamian culture. Appendices include lists of Bahamas native plants and their importance for wildlife; National Parks and Protected Areas; important birding areas of the Bahamas; a Checklist; a Bibliography; and a user-friendly Index (not all are…).
A good Checklist is a vital ingredient for any birder, whether visitor or local. Here, all the species occurring on the islands are shown on the left and their residential status and range throughout the islands across the top. Thus at a glance you can tell whether a given species is found on a particular island and when it may be found there. You would know not to look for Turkey Vultures on Eleuthera at any time; and that the black-bellied plover is a winter resident throughout the region and not to be seen during your trip in June… I also like the tick-boxes on the left for species collectors.
Overall I have thoroughly enjoyed this small book and unreservedly recommend it. It does not replace Hallett, but it complements it. Furthermore, I’m sure the straightforward style and presentation will appeal to bird-loving non-birders and also to younger birders – it may even encourage some out into the field! On p.20 the recommended reading list includes books that would appeal to young readers and links to appropriate websites, a thoughtful touch. I have learnt, or been reminded of, much from reading this book a couple of times. It is a welcome addition to the relatively sparse avian literature for the Bahamas, a prime birding region that is home to an astonishingly wide variety of birds including rare, threatened and vulnerable species like the Parrots, the Kirtland’s Warbler and the Piping Plover.
