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.

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…

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 Ring-billed Gull Larus delawarensis is a common winter gull, familiar to all in its adult form because of its… er… ringed bill that distinguishes it from all the other gull species found in the northern Bahamas. There are other differences, obviously, but this beak-related signifier provides the easiest method of ID. To be honest, you may find one anywhere – out to sea, on the shore, inland, or perhaps hanging out at one of the dumps that they are attracted to. This last preference is one shared with many species, but while the dumps may provide good birding venues, the photographic backgrounds and general ambience may be somewhat unattractive… Here are 3 great photos by Nina Henry of these gulls where they look best, near the shoreline.
STOP PRESSNov 18 Woody Bracey reports from Treasure Cay “I had my first for the fall here in Treasure cay yesterday – one adult and 1 immature. It’s nice to have them back”. So keep an eye out – the ring-billeds are back on Abaco…
The Latin name of these gulls refers to the Delaware River, Pennsylvania, which is on their migration route. But there must have been dozens of other towns along the route with equal claim to have a bird named after them. Why Delaware took the honours, I cannot explain… and thinking about it has inserted the old song in my brain “What did Delaware, boys? What did Delaware? She wore a brand New Jersey…” etc etc**. So I’ll get on and show some more RBGs to get it out of my head. Here are 3 stages of development from Bruce Hallett.
Juvenile
First winter
Adult
Laughing Gulls are gregarious creatures, and are quite often found in a group with some other seabird in the middle of the crowd – often a larger one. Here is a ring-billed gull standing proudly in the throng, while the laughing gulls snooze in the sun on the jetty.

Vireos haven’t had as much attention as they deserve hereabouts. I have posted about the BLACK-WHISKERED VIREO, but the 7 other vireo species found on Abaco haven’t had much of a look in. It’s a wrong that I shall right at once by featuring the rather shy Philadelphia VireoVireo philadelphicus. Here is the full list of the vireos recorded for Abaco, from which you will see that only the Thick-billed Vireo is a common permanent resident. The Black-whiskered vireo is a common summer breeding resident; there are 2 uncommon winter residents; and the other 4 are transients that chose Abaco as a resting place on their migrations.
Taken from ‘The Birds of Abaco’ checklist by Tony White with Woody Bracey
This little bird tends to be described with such unkind adjectives as ‘drab’, ‘dull’ and ‘plain’, but like many under-appreciated species it has its own charm. The header image and the one above give excellent close-up views. The signifiers include the dark eyes, white eyebrows, the dark line through the eyes, the yellow underparts, and in the negative sense the complete absence of eye rings, wing bars or tail markings. And the thick bill is one quick way to distinguish it from similar-looking warbler species, with their generally smaller, pointy beaks.
The Philadelphia Vireo has a wide range, from its summer breeding grounds as far north as Canada down to its winter quarters in Mexico and South America. They have even, very rarely, been seen in Europe. The connection with Philadelphia is somewhat tenuous and arises because the bird was first identified in 1842 from a specimen collected near Philadelphia. However their visits there are brief, since at best it is only a stopover on their migration route…
Here is the song comparison between (in order) the Philly, the familiar TBV whose song accompanies everyday life on Abaco, and the Black-whiskered vireo. My TBV recording is rather quieter than the other 2.

BUTTERFLIES ON ABACO (5): THE UNUSUAL MARTIAL SCRUB-HAIRSTREAK
I wish I could tell you something useful about this butterfly, but frankly there’s not a lot of info about it to be found. In part that may be because it is not a mainstream American butterfly, being found only in southern Florida. However it is found in the West Indies, and indeed on Abaco – this one was photographed by Nina Henry at Little Harbour. She was walking from Pete’s Pub to the OLD LIGHTHOUSEwhen she came across this butterfly. She sent it to me as a query and it took me an hour to nail the ID – there are other very similar and more common hairstreaks that threw me off track for a while (I thought it might be a female… oh, ever mind, it wasn’t).
The Martial Scrub-Hairstreak Strymon martialis ranges from the southern tip of Florida, throughout the Bahamas and Greater Antilles. I’ve never seen one on Abaco, and I’d be very interested to hear from anyone who has. As far as I can make out this creature’s range tends to be further south, so I’m guessing they are unusual for Abaco. Prove me wrong!
“STAR ANIS”: ENTERTAININGLY GREGARIOUS CUCKOOS ON ABACO
The Smooth-billed Ani (Crotophaga ani) is the third member of the cuckoo family found on Abaco, the others being theMANGROVE CUCKOOand theYELLOW-BILLED CUCKOO. Anis range from Florida and the Bahamas in the north, down through the Caribbean to South America, where they are widespread.
Unlike their shy and retiring cuckoo cousins, anis are extrovert shouty birds that like to hang out in noisy gangs. Large groups can quite often be found in the low scrub at the Highway end of the Delphi drive; and you may well find a posse of them in settlements such as Sandy Point. You’ll probably hear them from some way off, sounding like this:
Leonardo Ordóñez-Delgado / Xeno Canto
Anis have advanced parenting and chick-rearing skills, sharing not only communal nesting sites but also egg incubation and feeding the chicks. They are also what my mother might have called ‘fast’, raising up to three broods in a season. Rather touchingly, the young of earlier broods help to feed more recent chicks.
I have tried to discover why an ani’s beak is as it is, without much success. Very often beak shape relates directly to the feeding habits and preferences of a species, but it is hard to see how a diet consisting mainly of insects and small reptiles such as lizards would account for such a prominent proboscis. Here is a close-up of the item in question (thanks, Roselyn Pierce).
On Abaco (and indeed elsewhere) Anis are sometimes known as ‘Cemetery Birds’, no doubt because of their all-black appearance (their raucous tendencies would be quite inappropriate for a graveyard…). [Nicolette Russell has contacted me to say that she has always known them as Rain Crows] However although at a distance these birds may look completely black, catch one in the sun at the right angle, and you’ll find that the plumage is far more varied, and with some intricate patterning.
Look for Anis in low scrubland and coppice, cultivated areas, perched in unsteady bickering rows on utility lines… and on the ground.
The appearance and flying abilities of Anis are wonders to behold. As I wrote in The Birds of Abaco, “Their curious heavy beaks, their clumsy flight and their untidy take-off and landing routines suggest a design fault”.
“One… is the loneliest number…” oh, hang on a moment…
…”two of us…standing solo in the sun…”
As far as I know, there is not yet a collective noun for a group of anis. There should be. Any suggestions welcome via the comment box. Meanwhile I put forward “A Commotion of Anis”

“Star Anis” – do not confuse with Star Anise. One can fly, the other cannot
Cormorants are strange creatures. Strange to look at. Strange in their relationship with humans – love / hate in fishing terms and good / evil in mythology. Strangely useless for poetry, since – like the words ‘purple’ and ‘orange’ – there is no pure rhyme for the word cormorant. But they are undeniably striking, and a cormorant on the Abaco Marls effortlessly gliding inches above the water is an impressive sight.
The cormorant’s name originates from the Latin name ‘Corvus Marinus’, the Sea Raven. Cormorants belong to the ‘Pelican’ order of birds known as the pelecaniformes that also encompasses tropicbirds, frigatebirds and anhingas. Worldwide, there are around 40 different species of cormorant. In many parts of the world, this seabird has established itself inland. Angling communities are increasingly concerned by the spread of this bird along productive fishing rivers, often far from the sea shore. In the UK as elsewhere they are very bad news for prime fishing rivers.
Splosh! Gull Photobomb! It wasn’t there when I decided to press the trigger…Itchy neck? You just have to scratch it…Relaxed now, thanks…
The birds here were photographed in the UK on Halloween. While the world was preparing to immerse up to its neck in blood, guts, gore and spider webs, I was out armed only with a camera in unseasonably warm sunshine. So these are Great Cormorants Phalacrocorax carbo, the species found in the UK. They a remarkably similar to the Double-crested Cormorants Phalacrocorax auritus found on Abaco but larger and with a pale cheek and upper neck. This was a perfect day for the cormorants to enjoy their preening and wing-drying routines.
Last sight of the one on the small rock: “Hey, photographer, for !@£$%&* sake leave me alone, ok?”
I will be writing about Neotopic Cormorants Phalacrocorax brasilianus on Abaco in detail soon, but for comparative purposes here is one from Bruce Hallett taken on Teasure Cay Golf Course, where the ponds are usually a productive birding resource (check in at the clubhouse for permission first).
And as for the very familiar double-crested cormorant, here is a great photo taken on Abaco by Jim Todd of three chicks growing up fast in their unusual double-decker nest…

‘ATALA FASCINATING’: THE LIFECYCLE OF THE ATALA HAIRSTREAK ON ABACO
I have posted about several of the wonderful butterfly species the live on Abaco, but my favourite will always be the small but beautiful Atala Hairstreak Eumaeus atala. Its ‘look-at-me’ bright orange abdomen, black wings and the curious luminescent bright blue spots that even cover its legs and head are unmistakeable. These butterflies favour the coontie plant – especially for egg-laying – but they can be seen almost anywhere as far as I can see, though I have never seen one right by a beach.
I’ve posted before about the lifecycle of the Atala, but I have never had a chance to show the complete post-egg process from caterpillar to triumphantly emergent butterfly actually recorded on Abaco until now. Thanks to Rhonda Pearce, her patience and her skill with a camera, the following sequence of photos shows in detail the various stages of metamorphosis.

PS Sorry, I’ve been very po-faced and not mentioned Halloween. Everyone else is covered in blood, guts and gore, so I reckon the market is saturated. Also I get the wrong end of the ‘Trick or Treat’ stick. I carefully prepare 2 lots of choccy-based sweets. One is delicious. The other contains chilli. If the callers are nice, they get the Treat. If not, they get the Trick. That must be right, surely. I can listen to them hawking and barfing as they run off into the night…. [No children were hurt in the making of this story…]
So much to post about – what to choose? Well, the fall migration is still in full swing, with warblers hurtling across land and sea to Abaco in large numbers for their overwintering. Palm warblers are currently arriving. However I’m going to stick with shorebirds for now, and one of the rarer winter visitors, the Piping Plover. I have some more great photos from Danny Sauvageau in Florida, who tirelessly patrols the plover resting areas to record the banded ones so that their origin can be determined. This research assists with vital habitat conservation programs at each end of the migration. There are only 8000 of these little birds left in the world and without protection there’ll be none before you can say “oh dear, very pretty, they’re gone, what a pity…”
PIPING PLOVERS IN THE EARLY MORNING SUN
RING BLING & FLAG TAGS
The postions, colours and numbering of the rings and tags on these plovers identify individual birds, the location of their summer breeding grounds and so on. Dispersal and migration patterns of each bird can be recorded and specific facts – age for example – can be monitored.
PIPL IN FLIGHT – AN AMAZING IMAGE
On the very day I was about to press the ‘publish’ button on this post, look what just flew in from Danny’s beach in Fl.! This is an outstanding photo of a PIPL in flight – you can even see its shadow on the sand. I have a few shots of these birds flying in groups over the sea but apart from a general impression of PIPL-ness, they could really be any small shorebirds travelling fast on the wing. This one is special.
ABACO PIPL NEWS
Piping plovers have already arrived on Abaco. Casuarina beach is a promising place to look. Rhonda Pearce sent me this nice photo taken on the point (see my map). This pretty bird looks as though it has a black tag. However Todd Pover of CONSERVE WILDLIFE NEW JERSEY who also monitors the Abaco end of the migration thinks it may just be a piece of wrack – black tags are not usually used.
If anyone sees a piping plover and has a camera handy, I’d be very pleased to receive any photos, especially showing rings if possible – or indeed ringless legs, which is also informative to the monitors. If it turns out to be a Wilson’s Plover, no matter: they are fine birds in their own right!
Finally a quick reminder about Danny’s Kickstarter project “Saving Endangered Piping Plovers through Photography” and his presentation explaining how his photography in PIPL resting areas during their migrations can help to map and complete the picture of this vulnerable species to enable their protection.
You can reach Danny’s film by clicking the linkDANNY’S FILMand you will see some fabulous footage of these little birds scuttling around on the beach, looking enchanting; and the commentary will explain the importance of the the birds and the research into their conservation.
STANDIN’ ON THE DOCK OF THE BAY: GREAT BLUE HERON ON ABACO
The occasion: a trip to Sandy Point for a lunch party at the legendary Nancy’s in honour of Sandy Walker at the end of his 5 years as manager of the Delphi Club. A pair of brown pelicans on the nearby dock were clumsily flying around, diving, perching, drying their feathers, then repeating the cycle. In a quiet moment I slipped away to watch them – and a Great Blue Heron landed quite close by me. So as well as taking photos of the pelicans, I pointed the camera at the heron from time to time. My favourite view is of it standing proudly on the edge of the dock, with the truly azure sea behind it (header and final image).
THE PERILS OF A CAMERA UPGRADE
[PHOTOGRAPHIC INTERLUDE – SKIP IF EASILY BORED BY SUCH THINGS]
I don’t have a fancy camera. I would never get the settings right before the bird had flown. Or died, even. So I had been using a Panasonic Lumix FZ45 kindly given to me by Mrs RH in a benign moment, possibly Christmas. Then I made a classic error of upgrading to an FZ72 with an alleged massive 60X zoom. Brilliant, I thought. Big mistake. My old camera has a Leica lens. Used with care and a lens extension (zeugma score!), it is / I am occasionally capable of taking pin-sharp photos. The upgrade camera’s lens turned out not to be a Leica. Almost all the shots I took were ‘soft’, the more so using the zoom. A soft photo taken with a less good lens, zoomed 60X, will never be a better photo. Just an even softer one. I wish I’d had Old Faithful with me instead. When we got home, I immediately dug out OF and sold 60X disappointment. OF is now reinstated as my BF.
The shots of this heron mostly turned out fairly well, largely because it stayed quite close to me. It flew off a couple of times, then returned to the edge of the dock. Here are a few close-up views of the heron selected from the various pics I took, showing some of the details of this fine bird.Then I remembered why I was meant to be at Sandy Point, and went back to Nancy’s for conch fritters and a Kalik or two well OK make that three…
ROLLING HARBOUR MUSICAL DIGRESSION
Otis Redding recorded ‘Sittin’ on the Dock of the Bay’, arguably his greatest moment, in 1967 a matter of days before he died in a plane crash. The record became the first ever posthumous US Chart #1 (#3 in UK). I’ve dug out a video compo by the excellent Rhino outfit that disinters or at least recycles gems from our musical heritage. It’s not just the voice of Otis Redding that makes this song so poignant and so good – Steve Cropper’s guitar is outstanding too.
Guitarists out there – you want a ‘Chase Chart’, don’t you?
The White-winged Dove Zenaida asiatica is an easily recognised dove species, being the only one on Abaco with conspicuous white wing markings. The prominent blue eye-rings are another unusual feature of this bird. The blue is skin and not feather colouring. Another identifier is the dark line on the upper neck.
Although the birds are permanent residents on Abaco, they are relatively uncommon. They are not a protected species, and yet unlike some other pigeon and dove species (Mourning Dove, Ring Necked Dove, White-crowned Pigeon, Zenaida Dove) they are not listed among the game birds that have a shooting season. Unlike many species whose range is decreasing for all the usual human-related reasons, this bird appears to be expanding its range – or is possibly being introduced in new areas. Urban development seems not to be not such a deterrent as for other birds, and feeders are also thought to contribute to the spread.

FANCY THAT!
STEVIE NICKS name-checks the White-winged Dove and its call in her 1981 hit “Edge of Seventeen” from her Bella Donna album. If your interest is piqued as the Mac again discuss putting behind them their various differences and prodigious substance sampling to re-form (Glastonbury 2015?), see below. However, rehearing this again (having hidden Bella Donna in a locked drawer 30 years ago) the music has not worn well and her voice – sometimes so exciting – is somewhat fingernails on blackboard.
This final image is by Dan Pancamo who generously uploaded it to Wiki. It is several cuts above the usual generic illustrative images in both quality and style.

The NORTHERN PARULA Setophaga americana is a stumpy little migratory warbler with white arcs above and below the eyes, and with a slate-coloured back distinctively smudged with an olive patch in both sexes. These birds are winter residents on Abaco, and are common throughout the island and cays. They are arriving right now, including juveniles making their first trip to Abaco. Wonder what they’ll make of it?
This photo shows the distinctive colour difference between feet (orangey) and legs (grey-brown)
Range Map: Summer (Yellow) & Winter (Blue)
Parulas are primarily insect eaters, with a preference for caterpillars and spiders. They sometimes dart from a perch to snatch insect prey in mid-air. In winter they vary their diet with berries and fruit. You are most likely to see one foraging busily in bushes and low trees – maybe coming up for air by poking its head above the foliage…
TAXONOMY DOMINÉ
WHAT THE HECK IS A “PARULA”? Originally, Linnaeus classified this little bird at a Tit, or Parus. For some reason, “as taxonomy developed the genus name was modified first to Parulus and then the current form” (Wiki Hat-tip). But although none of the other 37 Abaco warbler species is a Parus, Parulus or Parula, they all come under the family name Parulidae. The august institutions that deal with these things have classified the Parula as a ‘Setophaga’, along with many other warblers.
This photo shows the distinctive upper chest band of the adult bird very clearly
The CORNELL LAB list of adult Parula identifiers is shown below, with adult females being similar ‘but with greener backs’. These specifics are pretty much borne out by the birds shown here (except for the last bird, an immature female just beginning to develop the Parula characteristics). The next photo by Woody Bracey, is a perfect example of what to look out for.

Blue-gray hood and wings.
Yellow chest with black and reddish band across it.
White crescents above and below eyes.
Green back.
Two white wingbars.
Parulas produce different sounds to listen out for – a ‘chip’ call that could be any number of birds (IMO); a song; and a trill. Here are examples of each from the essential bird call site Xeno Canto.

“50 WAYS TO PLEASE YOUR PLOVER”: PIPING PLOVERS ON ABACO (2)
There must be 50 ways at least, most of them amounting to leaving Piping Plovers alone and respecting their habitat. So, in many cases simply NOT doing things . Refraining from driving your SUV around on the beaches exactly where they are resting (with other shorebirds) during migration (yes, this very scenario is captured on film). Discouraging your canine friends from investigating their scrapes, eggs and chicks. Not building a concrete block on their favourite beach. Avoiding dumping quantities of oil in their vicinity. That kind of thing. Make a new plan, Stan! Watch where you drive, Clive! Find a new place, Grace! Safeguard your oil, Doyle! And leave the birds free…
MIGRATION & CONSERVATION I’m returning to Piping Plovers at a time when concerns for their diminished population has led to intensive research and protection programs at both ends of their migration routes. For a long time, their winter destination was a mystery. Recent investigations have helped to pinpoint the wintering grounds, which include Abaco. Ringing programs in the summer breeding areas mean that birds can be identified in winter and traced back to their origin. So if you are out and about and see one of these little guys – let’s say, on the beach at Casuarina – and you happen to have a camera with you, can I repeat the request to please take a photo, if possible showing the leg bling, and let one of the island birders (or me) know…
You can see how the PIPLs live through the seasons and their migrations in an excellent Audubon interactive presentation I have featured previously entitled “Beating the Odds: A Year in the Life of a Piping Plover”.CLICKBEATING THE ODDS
PIPL ON ABACO I shared this wonderful video from the reliably excellent CONCH SALAD TV on my FB page, but it’s such a great 15 minutes worth of Piping Plover information that I am including it in this post, not least because many of the the subscribers are different. The Bahamas in general and Abaco in particular are favoured by these delightful but rare and vulnerable birds for their winter habitat (sensible creatures). If you can spare 15 minutes and are interested in the importance of Abaco as a vital component in the conservation of migratory birds, do watch the video. Presenters include Todd Pover and Stephanie Egger of CONSERVE WILDLIFE NEW JERSEY, David Knowles of the BNT and Olivia Patterson of FOTE(Friends of the Environment, Abaco). One of the most heartening features is to see the responses of the young children who were encouraged to participate in the project, and who take to it with huge enthusiasm.
A while back, well-known and much missed Abaco naturalist Ricky Johnson made his own Piping Plover film incorporating his own trademark style and sense of humour. My original post about it can be seenHERE, but far better to go straight to Ricky’s video. It’s good to recall his infectious enthusiasm for the wildlife of Abaco. Impossible to watch without smiling…
The PIPL in this post all have two things in common. The wonderful photos are all taken by Danny Sauvageau; and all of the birds are differently ringed, reflecting their various summer habitats. So this brings me to Danny’s Kickstarter project “Saving Endangered Piping Plovers through Photography”. He has put together a superb presentation explaining his project, and how his photography in prime PIPL resting areas during their migrations back and forth can help to map and complete the picture of this vulnerable species to enable their protection.
You can reach Danny’s film by clicking the link DANNY’S FILM(there’s no obligation to go further and contribute) and you will see some fabulous footage of these little birds scuttling around on the beach, looking enchanting; and the commentary will explain the importance of the the birds and the research into their conservation.
FORK-TAILED FLYCATCHER: ANOTHER NEW SPECIES FOR ABACO
Following the flurry of reports and photos in June of Black-bellied Whistling Ducks on Abaco – a species never recorded here before – comes a new ‘first bird’: the Fork-Tailed Flycatcher Tyrannus savant. On September 24 Shirley Cartwright saw an unusual bird with a long dark tail and managed to get a photo of it of sufficient quality for a certain identification to be made. Never mind the photo detail, the fact that Shirley saw the bird and was able to obtain photographic confirmation is the thing. So here is the first-ever Fork-tailed Flycatcher for Abaco – and only the third for the Bahamas (previous ones seen on New Providence and Great Inagua).
I did a little brightening and clarifying of the original image, and also tried a crop
Tony White, the well-known authority on Bahamas birds, sent me the image with some information about this bird’s usual range:
“This is an interesting species as the race found in eastern US is South American and highly migratory. It breeds in Chile and Argentina. It is a frequent vagrant to USA, well over 100 records, and has appeared as far north as Nunavut, Canada. In the Austral fall (our spring) it migrates north and winters in Northern South America. Birds that appear in the USA at that time are considered overshoots. Birds that appear in our fall (Austral spring) are believed to be mostly first year birds that winter in northern South America and then fly a mirror image from the proper direction heading north instead of south. Unfortunately, the photos of the Abaco bird are not close enough to tell whether it was a young one or not. Field guides say young birds have shorter tails, but in fact there is considerable overlap in tail lengths between females and young. I strongly recommend a paper by McCaskie and Patton on this species in Western Birds 1994 Vol 25, No 3, pp 113=127. It can be found on SORA (Searchable Ornithological Research Archives).”
Treading carefully through a copyright minefield, I have dug out some illustrative images of this flycatcher, shown below. It belongs to the group known as tyrant flycatchers, which includes the kingbirds that are familiar on Abaco.
This first range map (Cornell Neotropical) shows the FTFs’ typical, largely subequatorial range
However this ‘overshoot’ range map (Audubon) reflects the fact that overshoots occur almost annually in the eastern United States seaboard and even as far north as Canada. To see these birds photographed in Connecticut (10000birds.com), clickHERE. Given that the whole Florida coast is included, it’s perhaps not surprising that sooner or later the odd bird would misdirect to the northern Bahamas.
This example of the species is taken from the Crossley ID Guide to Eastern Birds (open source) . The bird in the centre with the long tail is clearly a male; I imagine the mature-looking one on the left is a female; and the one on the right with the comparatively stumpy tail, a juvenile.
It’s sometimes instructive to discover how John James Audubon saw a particular bird, so here is his FWF. While the bird is undeniably beautiful, I am not too certain of its proportion in relation to the size of the blossom. But then again, it seems to me that he didn’t always struggle for exactitude, preferring a broader, more relaxed approach to depict the birds as he saw them – and not afraid to exaggerate a characteristic for effect.
NEW INFO Woody Bracey has contacted me to point out that the male in the image above “is actually a pale mantled manachus subspecies from Central America, not the darker savana nominate subspecies from South America which Shirley photographed”. Which explains the colour difference.
ESSENTIALFUN FACT
The fork-tailed flycatcher has the longest tail relative to body size of any bird on earth (trails.com)
As the name suggests, this species feeds mainly on insects, although in winter it may also eat berries and the like. They will often perch on wires of fence posts. I’ve no idea if they ‘hawk’ for flies on the wing, but if so the sight of a male feeding must be wonderful. Here is an example of their song

Yesterday I posted a complete guide to Abaco’s 37 warblers. A few people said nice things about it. Two people spotted a mistake (my bad!), now corrected. It has now occurred to me that it might be helpful to reduce the contents to a shorter PDF so as to make the guide more handy – plus you will be able to print it out. If you click the link below, you can save the 1.6 mb ‘booklet’ onto your computer desktop / iPad / tablet / etc. You can email it to your phone and save it there. For an iPhone, you have the option to have a ‘quick check’. I you want to keep it, you can ‘cloud’ it, or save it in various ways on the phone, for example to iBook or Kindle if you have the App. I expect other cellphone types are much the same. I have road-tested the system, and it works! So if one sunny day you suspect you are looking at a Bay-breasted Warbler (highly unlikely, but possible) in that small bush over there… yes look, near the top on the left… no, on the long twig lower down… you can check it out.
And here’s the thing. You have a camera in your hand to record the encounter. And if the little rascal is happily singing away, you can use you phone to record it, using a simple technique I have previously described – check out the link.
AN ILLUSTRATED GUIDE TO ABACO’S 37 WARBLER SPECIES
The winter warblers are arriving on Abaco right now, and a couple of people have already sent me ID queries. Until a couple of years ago, I lazily believed all of the warblers were near identical, differing only in their extent of yellowness. Not so. I know better now. Their arrival now has prompted me to devise a general guide to all the various warblers, so that the great diversity can be appreciated. The photos that follow show an example of each warbler, where possible (1) male (2) in breeding plumage and (3) taken on Abaco. Where I had no Abaco images – especially with the transients – I have used other mainstream birding resources and Wiki. All due credits at the foot of the post.
Abaco has 37 warbler species recorded for the main island and cays. They fall into 3 categories: 5 permanent residents (PR) that breed on Abaco (B), of which two are endemics; 21 winter residents (WR) ranging from ‘everyday’ species to rarities such as the Kirtland’s Warbler; and 11 transients, most of which you will be lucky to encounter. The codes given for each bird show the residence status and also the likelihood of seeing each species in its season, rated from 1 (very likely) to 5 (extreme rarities, maybe only recorded once or twice).

CHECKLIST based on the complete checklist and codes for Abaco devised by Tony White with Woody Bracey for “THE DELPHI CLUB GUIDE TO THE BIRDS OF ABACO” by Keith Salvesen
I’d been planning a post about marine debris and its dire effects on the natural world. Some images I proposed to use are distressing, and some simply suggest how futile it is to try to prevent mankind chucking harmful and semi-permanent rubbish into the sea. Depressing. A gyre of upset. Add in new military interventions without limitation and suddenly I longed for something more cheerful. Checking through a folder of photos of Bananaquits helped to stave of the gloom, so I picked out a few images of this lovely small bird taken by 9 photographers.
