I wrote this post about Royal Terns Thalasseus maximus* quite some time ago, in the early days of Delphi (and indeed Rolling Harbour™ ® ). Bonefishing was a completely new experience and my skills were embryonic. As they continued to be for the duration. By then the amazing birdlife of Abaco had reeled me in and BIRDS OF ABACO was in the planning stage.
If there’s a magnificent golden bandwagon drawn by 8 horses passing by, why not just hop on? I’ve skipped the info about the range and nesting arrangements of these birds. Here are a few, in all their regal glory, posing in the sunshine on a dead tree way out on the Abaco Marls. The header image was taken on Cherokee Long Dock, long pre-Dorian and its magnificent replacement.
** Now to be renamed Thalasseus carolus rex magnificans. Not worldwide, obviously.

The Pine Warbler Setophaga pinus is one of 5 year-round resident warblers (endemics) on Abaco. All are to be admired, of course. The others are Bahama yellowthroat; Bahama warbler; olive-capped warbler; and yellow warbler.
The pine warbler is also to be envied for several reasons:
Like most Setophagae, they are bright, lively and attractive birds
Bahamas residents all year round – no long exhausting migration flights twice a year
Abaco has vast areas of their preferred pine forest habitat
They are plentiful – the population is largely untroubled by usual habitat concerns
They are one of the few seed-eating warbler species, so feeders are a bonus
As the name strongly hints, the pine warbler is primarily a bird of the pine forests, of which Abaco has an abundance. The tall, straight trees of Abaco were once a vital local source of timber (SAWMILL SINKq.v.). As a historical note, felled pines were also exported to the UK to be made into the strong pit-props needed for coal-mines.
Immature
Q. WHAT IS THE NORMAL YEAR-ROUND RANGE OF THIS BIRD? A. THIS IS!
Pine warblers have a broad diet and forage methodically. Pine cones are a fertile source for food, and those robust, stabby, slightly down-curved beaks are ideal for getting the seeds out of the cones. Equally, these warblers use their beaks to prise / pry out insects from the rough pine trunks and branches.
WHAT OF THEIR NIDIFICATION?
The pine forest is obviously the preferred nesting habitat for these birds. The warblers also nest in the smaller groups of pines found (for example) in or near some of the settlements; or in backcountry around the edges of former sugar cane fields and the like. One nesting habit is slightly unusual – pine warblers tend to build their nests near the end of branches rather than near the trunk, a position that seems far less secure. One theory on pine warbler nest location is that they feel safer from predators by building at the end of a small branch*.
WHAT DO THEY SOUND LIKE?
One source states that “The song of this bird is a musical trill. Their calls are slurred chips“. I think we’ve all been there at some time, possibly when lunching at Pete’s Pub.

The Great Egret is actually a heron rather than an egret. It’s a Great Heron. All egrets are members of the heron family Ardeidae, but the converse is not true. As long ago as 1758,Linnaeus awarded the bird the binomial name Ardea alba i.e. ‘Heron white‘. Why it should have been so hard to stick to that authoritative nomenclature, I can’t imagine. Perhaps in time all heron and egret species became so hopelessly confusing for people that it ceased to matter much what they were called.
Maybe it was that type of carelessness that led to people from the mid-c19 onwards eyeing up GREGs as a source of hat feathers and other decorative necessities. As with flamingos and many other beautiful avian species, mankind’s millinery and other fashion needs were satisfied at the expense of gorgeous plumage. Actually, at the cost of the birds’ lives: they were simply shot in huge numbers.
Healthy populations were decimated; for some species they never recovered. For others, the great egret among them, the passage of time and the passing of fashions – backed in many cases with conservation programs – have successfully restored the populations. In 1953 theNational Audubon Society, which was formed at least in part to discourage the killing of birds for their feathers, took a decisive step in the cause of the great egret by making the bird the emblem of the organisation.

The Smooth-billed Ani (Crotophaga ani) is one of three members of the cuckoo family found on Abaco, the others being theMANGROVE CUCKOO and 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 and family groups. They can often be found in low scrub, bickering, squawking, and generally fluttering around in a disorderly way. You’ll probably hear them from some way off, sounding like this:
Anis have advanced social, parenting and chick-rearing skills. They build a communal nest for the group, and all share in egg incubation and chick-feeding duties They may raise up to three broods in a season, which keeps the numbers up. Rather touchingly, the young of earlier broods help to feed more recent chicks.
It follows from this that unlike many other cuckoo species, the ani is not a brood parasite. So the species does not lay its eggs in the nests of other, smaller birds which then unwittingly rear the interloper(s), who in turn push the legitimate hatchlings out of the nest and get all the food and attention.
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 prominently protuberant proboscis. Here is a close-up of the item in question.
On Abaco (and indeed elsewhere) Anis are sometimes known as ‘Cemetery Birds’, no doubt because of their all-black appearance (though their raucous tendencies would be quite inappropriate for a graveyard). 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 noisy rows on utility lines, or foraging 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”.
AIMEE MANN INTERLUDE **
“One… is the loneliest number…” Oh, hang on a moment…
…”two of us…standing solo in the sun…”
The Philatelic Bureau of the Bahamas Postal Service is commendably committed to featuring the natural history of the Bahamas. Although probably not in the top-ten of anyone’s bird list, the ani nevertheless got its own stamp in a 1991 bird issue.
As far as I know, there is not yet a collective noun for a group of anis. There should be. I put forward “A Commotion of Anis”
DO NOT CONFUSE WITH STAR ANISE

I have featured bird comparatives from time to time, not least because scope for confusion meant that I needed to investigate for my own peace of mind. These included the tyrant flycatchers; a number of superficially similar warbler species (mostly with yellow bits); varied vireos; all those heron-y / egret-y types and their disconcerting morphs (hello, white reddish egret).
And so to the magnificent osprey Pandion haliaetus. This time, the comparison is between two subspecies, broadly the North American P. h. carolinensis and the Caribbean P.h. ridgwayi. There is some overlap in Florida, and some evidence of interbreeding. In the northern Bahamas in particular there is also an overlap, so an osprey seen on Abaco could be either variety. You’ll probably be too excited watching it to care much which type it is, but this article will help you if you do…
The two ospreys shown below were photographed at Spanish Wells, Eleuthera by Barbara Crouchley. This is a ‘bingo’ photographic scoop, because each type of bird was found in the same region; now we can check out the differences between the two birds.
The first is a North American bird. Note in particular its distinctive eye mask, and the clearly marked upper breast – more so in the female than the male (which may even be white). The overall impression of the upper-parts is dark brown. They are slightly larger than their cousins in the south.
Osprey P.h. carolinensis
In this Caribbean bird, below, with its trophy fish, the eye-mask is absent and the facial / nape markings are less pronounced. Furthermore, the breast and under-parts are white in both sexes (though slight marking may be apparent in some birds). And the impression is of lighter upper-parts, even allowing for variable lighting and distance when the photos were taken. Conveniently, there’s not much detectable difference between male and females in the respective populations.

EXAMPLES OF P. h. carolinensis
EXAMPLES OF P. h. ridgwayi
THE EYES HAVE IT?
After I had looked into the noted distinctions I wrote “I’m going to stick my neck out here – I’ve not seen this mentioned anywhere, and I need to do some more comparative research”. When I saw Barbara’s pair of photos, I noticed that the eyes of the P.h.r were much paler compared with the bright orangey-yellow of P.h.c. This distinction is found in all the comparative photos above. The P.h.cs were photographed in Florida and further north and have the strikingly vivid eyes. The P.h.rs were photographed on Abaco and Grand Bahama at different times by different people. All have noticeably paler irises, more a light greeny-yellow.
I haven’t seen this commented on since my original piece, but if anyone has a view it would be welcome.
UNDERWING DIFFERENCES
There’s a further comparison that can be made with the two subspecies in flight. Without going into technical and linguistic detail, the underwings of the P.h.cs are much darker than the Bahamas birds, whereas P.h.rs are notably paler and in some cases mostly white. As an example, below is a distance shot I took when bonefishing out on the Abaco Marls, with a small pocket camera in one hand and a rod in the other. This is definitely a local bird! Compare with the dramatic image below it, where the strong darker markings are all too evident. It’s a great shot with which to bring the lesson to an end.
ADDENDUM: Thanks to LSulikM for pointing out that female carolinensis (besides being larger than males) have frontal freckling, sometimes called a necklace, that is a prominent ID marker (see bottom image). Males may also have freckling but it is much less conspicuous. For ridgwayi the freckling is absent or (see the bird on the utility pole above) very sparse.

Thanks to all followers, likers, commenters, regular visitors, one-offs, local wildlife organisations, and friends of Rolling Harbour in general. This year we passed 1 million hits over the ten years of this blog. Proving that people love Abaco, the Bahamas, birds, marine mammals, manatees, reef fish, sharks, turtles, shore-life, shells, insects, plant life, bonefishing, lighthouses, local history, maps, conservation and a whole lot more; and are prepared to tolerate bad puns, haphazard presentation, and a less than rigourous scientific approach to it all.
Weirdest search term ever: How to dispose of dead bodies?
There are 3 cuckoo species recorded for Abaco, all permanent residents. Two are relatively scarce; the third is the much-loved gregarious and raucous Ani. Recently I was contacted about a cuckoo seen on Man-O-War Cay. The photo revealed more of a glimpse than a sighting… but it clearly was not an all-black Ani. So here are the 3 species to admire in all their glory – and in the case of the first 2, to highlight the differences between them.

The history of ornithological classification and nomenclature is littered with peculiarities. The attractive migratory Cape May Warbler Setophaga tigrina is a very good example of premature evaluation.
The range of the species is well defined. In the summer the birds live within a broad band that straddles northern USA and Canada. In the winter they head south with all their migratory warbler cousins across the yellow band to (mainly) the Bahamas.
As with all migratory species, some birds each year will wander or be blown off-course; or will take a rest stop en route and decide to stick around. And so it was that in May 1812, a month before the Battle of Waterloo, the first ever specimen of the species was collected on Cape May NJ by George Ord during an exploratory trip with naturalistALEXANDER WILSON(he of plover & snipe fame). To be specific, they had gone to shoot the birds they wanted to collect. The bodies, from large down to tiny, were after all the only irrefutable evidence of a new ‘find’ at that time. Detailed drawings could be made and descriptions composed. The later display of the specimens enabled the expansion of ornithological knowledge and methodology, and brought consequent renown. The great Audubon took the research method *treading very carefully here* rather further than one might be comfortable with today, with somewhat indiscriminate use of lead shot.
As Wilson later wrote (note the words ‘beautiful little species, ‘shooting excursion’ and ‘ransacked’):
THIS new and beautiful little species was discovered in a maple swamp, in Cape May county, not far from the coast, by Mr. George Ord of this city, who accompanied me on a shooting excursion to that quarter in the month of May last…The same swamp that furnished us with this elegant little stranger, and indeed several miles around it, were ransacked by us both for another specimen of the same; but without success. Fortunately it proved to be a male, and being in excellent plumage, enabled me to preserve a faithful portrait of the original.
The odd (indeed ‘Ord’) thing was that the first-ever specimen was a complete one-off in that location at that time. Not a single sighting of the species (named Sylvia maritima by Wilson) was reported on Cape May or in that area for more than a century. Then at last in 1920, another example was found. Nowadays the CMW is not in the least unusual in the location that gave it its name.
On Abaco, CMWs are classified as WR1, which is to say common winter residents. Males have striking chestnut cheeks in the breeding season, with strong streaking on the underside. Note also the black eyestripe. Females and juveniles are paler and the marking is less prominent. These warblers are insectivorous; in winter they may also feed on nectar and fruit. Behaviour-wise, they have aggressive tendencies in defence of their territory and of their food sources.
In researching this post, I discovered a strange (but slightly dull) fact. The CMW is unique among warblers in having a tubular tongue to enable nectar feeding (as with hummingbirds). This random fact hardly has the makings of lively conversation (though you might want to try it out) but considering the multitude of warbler species in existence, the CMW has the benefit of a rather special adaptation.
Tongue 2 (bottom left) is the CMW; No.5 is a bananaquit’s feathery tongue
WHAT SHOULD I LISTEN OUT FOR?
Unhelpfully, even the authorities have a tough time describing the song and call of a CMW. As with so many song-birds, variations on the theme “the song is a simple repetition of high tsi notes; the call is a thin sip” are the best you can hope for. However, it’s worth noting that the species generally prefers to sing from high perches, which might help with ID. But then so do other warblers I’m afraid. Here’s something more practical – the tsi and the sip:

Abaco’s birding records compiled for over 20 years include 33 shorebird species. For a few, the islands and cays are a permanent residence; for many others they are winter quarters; some species are visitors transient in their migrations; a few are rare vagrants. The complete checklist of Abaco’s shorebirds is below, along with 3 links to specific posts.
I have divided the species into 3 categories: sandpipers & kin; plovers; and a catch-all ‘large shorebird’ group that includes one or two sandpipers. Of the 26 birds featured and shown in the main checklist below, 23 are ones you might reasonably hope or expect to encounter on Abaco, though some only if you are lucky or your field-craft is excellent. The others are the long-billed dowitcher, American avocet and Wilson’s phalarope (of which only one has ever been seen on Abaco, with a photo to prove it). Many of these are showcased in my book The Birds of Abaco.
The codes tell you, for any particular bird, when you may see it (P = permanent, WR = winter resident, TR = transient, V = vagrant); whether it breeds (B) on Abaco; and your chance of seeing it, graded from easy (1) to vanishingly unlikely (5).

And not just the tail*. Other parts of a bird. Sometimes most of a bird. More rarely, an entire bird. Whichever, a bird affected by leucism stands out from the crowd – out of the ordinary and therefore startling to the eye. I’d be very surprised if the fine turkey vulture in the header image didn’t make you look twice – maybe even to check if some devious photoshop trickery had been at work. Yet it’s just a normal TUVU in the Florida Keys, living a normal vulturine life.
LEUCISTIC DISCOVERY ON ABACO
A leucistic Western Spindalis discovered on Abaco by birder Keith Kemp
For comparison – the real deal
LEUCISM? EXCUSE ME, AND THAT IS?
First, what it is not. It is not albinism, which results from diminished or lost melanin production that affects pigmentation. One characteristic of the condition is the tendency to pink eyes, which of course is seen in humans as well as animals and birds. Meet the perfect example…
WELL, WHAT IS IT THEN?
Put simply, melanin is only one of many ingredients of pigmentation. Leucism is caused through pigment loss involving many types of pigment, not just melanin. In birds this results in unnaturally light or white colouring of feathers that may be partial or entire. The eyes of a bird with leucism are unaffected. At one extreme, if all pigment cells fail, a white bird will result; at the other extreme, pigment defects cause patches and blotches of pale or white on the bird, often called a ‘pied’ effect. The condition can be inherited.
A mallard on Abaco. The species is known for its wide colour variations in both sexes. Sometimes the variations go beyond the usual range: this is a leucistic bird

BAHAMA (WHITE-CHEEKED) PINTAIL: A PIGMENT PUZZLE
I have found more examples of leucism in the ‘Bahama Duck’ than any other local species on Abaco. But there is also scope for confusion. First, here’s a pintail that is undoubtedly leucistic – note that the eyes and beak are unaffected by pigmentation deficiency:
But not all pale variants can be so confidently labelled. In the first picture, bottom right, there is an obviously an ‘odd’ pintail, silvery rather than ruddy brown like the rest of them (and yes, I do see the coot in the pack as well…). The second photo shows the same bird on dry land.
This is known as a ‘silver pintail’. These are said to be a leuchistic variant, and they are stocked by poultry dealers as ornamental ducks at a higher price than the much-loved standard brown version. However this bird clearly retains the essential markings of a normal pintail that you might expect to be absent (at least in patches) in the ‘true’ leucistic bird. I’ve seen it described as a ‘gray morph’. I wonder where the line is drawn between a noticeable colour variant or morph in a bird; and an obviously pigment-abnormal, leucistic bird where the incidence and extent of the condition seems to be random.

PIPING PLOVERS CAN BE LEUCISTIC TOO
PIPL are one of my bird species preoccupations, but until I checked them out I hadn’t imagined what a leucistic one would look like, or whether they had ever been recorded. I now have the answer…
These photos of a leucistic female were featured by Audubon Alliance for Coastal Waterbirds, Audubon Connecticut. They were taken by Jim Panaccione, a Biological Science Technician at Parker River National Wildlife Refuge, Newburyport, Massachusetts. I hope he won’t mind their illustrative use here… Despite the theory that leucistic birds may find it hard to find a mate – and might even be attacked by its own species – this pair successfully nested.
OPTIONAL MUSICAL & CULTURAL DIGRESSION
A WHITER SHADE OF PALE
*Obviously, it had to be ‘tail’ in the title to justify one of my clunky ‘jokes’ and an accompanying musical diversion. That’s just the way it is, I’m afraid. Bach’s well-known descending chord sequence of was of course shamelessly ripped off by ingeniously adapted by Procol Harum for ‘A Whiter Shade of Pale’, their first single in 1967. Relive a Summer of Love right here and now.
Any fret-tweakers might like to see the sheet music of Bach’s Air for guitar – you could even play it on Air Guitar – which is relatively easy, being in C major.
‘BACH IN A MINUET’
The best known commercial use of the tune was in the famed series of adverts that equated a mild cigar called Hamlet with happiness, accompanied by an excerpt from a jazzy version of Bach’s ‘Air on the G String’. Here is one of the best – and possibly the only advert to my knowledge to feature not one, but two excellent Sir Walter Raleigh jokes.

The gull-billed tern Gelochelidon nilotica had a name upgrade from Sterna nilotica some years ago, and was awarded the honour of its own genus.
Let’s be clear at the outset: there’s no such thing as a tern-billed gull. Which fortunately lessens the scope for species confusion.
There are 12 species of tern recorded for Abaco. Only one, the royal tern, is a permanent resident. There is one winter resident, the Forster’s tern and there a 6 summer resident terns of varying degrees of commonness. The other 4 are transient or vagrant, and probably definitely not worth making a special trip to Abaco to find. The G-BT is designated SB3, a summer breeding resident that is generally uncommon, though may be more common in particular areas.
TERN TABLE****I know! Too tempting…
The bird gets its name from it short, thick gull-like bill. It’s quite large in tern terms, with a wingspan that may reach 3 foot. They lose their smart black caps in winter.
There are 6 species of G-BT worldwide, and it is found in every continent. While many terns plunge-dive for fish, the G-BT mostly feeds on insects in flight, and will also go after birds eggs and chicks. Small mammals and amphibians are also on the menu. The header image shows a G-BT with a small crab. I always imagined that they must eat fish. Surely they do?But I have looked at dozens of images online to find one noshing on a fish, with no success.
All photos were taken by Alex Hughes, a contributor to THE BIRDS OF ABACO, when he spent some time on Abaco some years ago in connection with the conservation of the Abaco Parrot and the preservation of the habitat integrity of their nesting area in the Abaco National Park
The drastic effects of Hurricane Dorian on Abaco’s birdlife continue, with recent reports suggesting that all species remain affected, and some severely so. However there are signs of a slow improvement, and this good news includes the two hummingbird species, the endemic Bahama Woodstar and the Cuban Emerald. A couple of recent posts on FB indicate that sightings of both these species have been a very welcome surprise. So, a good time to write about them and to show their beauty.
Cuban Emerald (male) Abaco (Charlie Skinner)
The subject matter of this post is not as indelicate as the title might imply; nor is it a ‘hands-on’ practical guide for intimate examinations of tiny birds. In particular it does not publicise some recently discovered louche activity involving unfeasibly large motor vehicles. It’s all about plumage and recognition. And there are only two species – and two genders for each one – to wrestle with.So here are the adult male and female Bahama Woodstars and Cuban Emeralds in all their glory…
And finally, a brilliant Woodstar photo taken by Tom Sheley, birdman and generous fishing partner, that I spans the boundary between wildlife photography and art.

PAINTED BUNTING
Few birds radiate Yuletide vibes better than Painted Buntings, with their perfect festive colours. Here is a seasonal flock of them to enjoy. A very happy Christmas to those who kindly continue to visit Rolling Harbour, despite the unavoidable absence from the Bahamas of the Harbourmaster.
There’s nothing like a massive house clear-out (after 42 years) to reveal lost possessions, forgotten treasures, and (for that matter) a few things best forgotten… Last Spring we began to prepare for a house-move, during which I found a box of bird books that I duly reported here (and happily sold). Recently, sorting through a packed shipping container parked in the unlikely setting of a local farm has revealed plenty of surprises, including a couple more boxes of BIRDS OF ABACO. There definitely aren’t any more. There may be one or two people who might like one / who lost their copy during Dorian / who are new to Abaco and its wonderful birdlife. Here is a chance to own one…
In the spirit of recycling I am reusing the original blurb because it still holds good today. The book is only ‘out of date’ to the extent that since publication about a dozen new species have been reported. Most were seen just the once, some for a few weeks at most. So although exciting, the newcomers were more ‘Birds Passing Through…’ than ‘Birds Of…’ Abaco
The originator of the idea for the book – as with the entire Delphi Club project – was Peter Mantle, the publisher. He took a risk based on my (then) quite feeble Rolling Harbour blog about the birds and other attractions of the island. The 2kg book took 16 months from conception to the arrival of three pallets of printed books on the dockside in Marsh Harbour, having travelled by a tortuous route from specialist printers in Italy.
As part of the project, Abaco schools, libraries and wildlife organisations were given copies for educational purposes. A percentage of profits was given to local wildlife causes. We quickly sold a great many copies, and couldn’t have been more pleased with the response to the book, a unique publication for the Bahamas. The captions (below) about the book and content were written much nearer the time, so I’ll leave them as they are. I hope you enjoy the photos even if you don’t want a copy!
The Guide showcases the rich and varied bird life of Abaco, Bahamas and features both resident and migratory species including rarities and unusual sightings. The main features are as follows:
272 pages with more than 350 photographs
163 species shown in vivid colour – nearly two-thirds of all the bird species ever recorded for Abaco
Every single photograph was taken on Abaco or in Abaco waters
All birds are shown in their natural surroundings – no feeders or seed trails were used
Several birds featured are the first ones ever recorded for Abaco or even for the entire Bahamas
A total of 30 photographers, both experienced and amateur, contributed to the project
The book has had the generous support of many well-known names of Abaco and Bahamas birding
A complete checklist of every bird recorded for Abaco since 1950 up to the date of publication was compiled specially for the book.
A neat code was devised to show at a glance when you may see a particular bird, and the likelihood of doing so. Birds found at Delphi are also marked.

The project manager and the author personally oversaw the printing
The book is dedicated to the wildlife organisations of Abaco
A percentage of the proceeds of sale will be donated for the support of local wildlife organisations
A copy of the book has been presented to every school and library on Abaco
The book is published by the Delphi Club. The project was managed by a publishing specialist in art and architecture books. The author is the wildlife blogger more widely known on Abaco and (possibly) beyond as ‘Rolling Harbour’. Oh! So that would in fact be Mrs Harbour and myself. Well well! What were the chances?

There are twelve species of tern – ‘swallows of the sea’ – that to a greater or lesser extent may be found on Abaco. Whether they will actually be visible at any given time is less certain, though. For a start, the only resident species is the lovely Royal Tern, available at many locations on Abaco and the cays throughout the year. The rest are migratory or just passing through.
PERMANENT RESIDENTS
ROYAL TERNS Thalasseus maximus PR1
MIGRATORY TERNS: SUMMER
In the slightly less commonly-found category are the summer migrant terns that, by definition, are only in residence for around half the year. Four of these are fairly common in certain areas, and actually breed on Abaco; these include arguably the prettiest of all, the bridled tern. The other two tern species (gull-billed and sandwich) are more rare and as far as I can make out do not breed locally; or perhaps only rarely.

There is one very rare winter resident migratory tern species, with few records of sightings for Bahamas and until early 2019, no photographic record for Abaco until Sally Chisholm saw one at Treasure Cay and managed to capture it for posterity.

OCCASIONAL & RARE VISITORS
A further four tern species are very much occasionals that drop by. Three of them pass over the Bahamas on their longer migration, but may make a pit-stop around Abaco to take on fuel. Likelihood of sighting one? Slender but not impossible… the Caspian tern below was photographed on Abaco. The fourth, the Arctic Tern, is a very rare vagrant, a bird well away from its usual home or migration route as the result of storms or faulty satnav or sheer happenstance. Don’t travel to the Bahamas intent on seeing one.
CASPIAN TERN Hydroprogne caspia TR 4
The remaining species are the transient black tern and common tern; and the vanishingly rare vagrant Arctic tern. No photos of any of these I’m afraid. Here’s a handy checklist of all the tern species.
ELECTIVE MUSICAL DIGRESSION
Written by Pete Seeger, Turn x 3 was released in 1965, the title track on the second album by The Byrds. At a rather febrile time in US history (Vietnam, draft riots, civil rightists v cops and so on), this unusually palliative and thoughtful song with its religious connotations to some extent stood for peace and hope in a time of turmoil.
PS the somewhat laboured title of this post shoehorns in the name of another Byrds album, ‘The Notorious Byrd Brothers’

‘CARRION SCAVENGING’: TURKEY VULTURES IN ABACO BAHAMAS
Turkey Vultures (Cathartes aura) manage to be simultaneously majestic, hideous, revolting and socially vital, all packed into a single species… Right now there is a slew of online excitement about them, although it can’t be because it is ‘International Turkey Vulture Appreciation Day, which is on September 4th. Anyway, it’s always a good time to join a flock of admirers.
THE FACTS
The word ‘vulture’ derives from the latin word ‘vulturus‘ meaning ‘ripper’, ‘shredder’, or ‘very loud Metallica song*‘.
TUVUs have very good eyesight, and an acute sense of smell that enables them to detect the scent of decay (from the release of the chemical ethyl mercaptan) from a distance. A breeding pair will raise two chicks, which revoltingly are fed by the regurgitation of all the rank… oh, you fill in the rest…
These vultures are often seen in a spread-winged stance, which is believed to serve multiple functions that include drying the wings, warming the body, and baking bacteria. Possibly it also reduces the miasma of rotting meat that may surround them after a good meal.
TUVUs like best to perch on a vantage point – utility posts or wires are ideal.
You won’t ever hear them sing or call. They lack aSYRINX(the avian equivalent of a larynx), and their vocalisation is confined to grunting or hissing sounds. Here’s a hiss (at 10 / 15 secs).
10 SCAVENGED TURKEY VULTURE FACTS FOR YOU TO PICK OVER
One local name for TUVUs is ‘John Crow’
An adult has a wingspan of up to 6 feet
Sexes are identical in appearance, although the female is slightly larger
The eye has a single row of eyelashes on the upper lid and two on the lower lid
TVs live about 20 years. One named Nero had a confirmed age of 37
LEUCISTIC (pale, often mistakenly called “albino”) variants are sometimes seen
Leucistic TUVU
TUVUs are gregarious and roost in large community groups
They have few natural predators (perhaps for reasons of their hygiene deficiency)
Though elegant in flight, and users of thermals, they are ungainly on the ground and in take-off
The nostrils are not divided by a septum, but are perforated; from the side one can see through the beak
REVOLTING CORNER / DEPT OF ‘WAY TOO MUCH INFORMATION’
SQUEAMISH? THEN LOOK AWAY NOW
UNATTRACTIVE HABITS The Turkey Vulture“often defecates on its own legs, using the evaporation of the water in the feces and/or urine to cool itself, a process known asUROHIDROSIS.This cools the blood vessels in the unfeathered tarsi and feet, and causes white uric acid to streak the legs”. The droppings produced by Turkey Vultures can harm or kill trees and other vegetation. Maybe don’t park your nice car under one of their perching posts…
HORRIBLE DEFENCES The main form of defence is“regurgitating semi-digested meat, a foul-smelling substance which deters most creatures intent on raiding a vulture nest. It will also sting if the predator is close enough to get the vomit in its face or eyes. In some cases, the vulture must rid its crop of a heavy, undigested meal in order to take flight to flee from a potential predator”
DIETARY NOTES TUVUs tend to prefer recently dead creatures, avoiding carcasses that have reached the point of putrefaction. They will occasionally resort to vegetable matter – plants and fruit (you could view this as their side-salad). They rarely, if ever, kill prey – vehicles do this for them, and you’ll often see them on roadsides feeding on roadkill. They also hang around water, feeding on dead fish or fish stranded in shallow water.
ECO-USES If you did not have birds like this, your world would be a great deal smellier and less pleasant place, with higher chance of diseases from polluted water and bacterial spread. TUVUs kept the highways clear and work their way round the town dumps recycling noisome items. Humans need them although, conversely, they don’t need humans.
FORAGING TUVUs forage by smell, which is uncommon in birds. They fly low to the ground to pick up the scent of ethyl mercaptan, the gas produced by the beginnings of decay in dead animals. Their olfactory lobe in the brain is particularly large compared to that of other animals.
SEX TIPS Courtship rituals of the Turkey Vulture involve several individuals gathering in a circle, where they perform hopping movements around the perimeter of the circle with wings partially spread. In humans, similar occasions are called ‘Dances’. A pair will fly, with the female closely following the male while they flap & dive… then they land somewhere private and we draw the veil…

*As Metallica so appropriately wrote and sweatily sang (luckily there’s no verse referencing urination, defecation and puking). ALERT don’t actually play the video – the song hasn’t aged well! In fact… it’s terrible. Woe woe indeed…
The vultures come See the vultures come for me Fly around the sun But now too late for me Just sit and stare Wait ’til I hit the ground Little vultures tear Little vultures tear at flesh
The Great Egret is actually a heron rather than an egret. It’s a Great Heron. All egrets are members of the heron family Ardeidae, but the converse is not true. As long ago as 1758,Linnaeus awarded the bird the binomial name Ardea alba i.e. ‘Heron white‘. Why it should have been so hard to stick to that authoritative nomenclature, I can’t imagine. Perhaps in time all heron and egret species became so hopelessly confusing for people that it ceased to matter much what they were called.
Maybe it was that type of carelessness that led to people from the mid-c19 onwards eyeing up GREGs as a source of hat feathers and other decorative necessities. As with flamingos and many other beautiful avian species, mankind’s millinery and other fashion needs were satisfied at the expense of gorgeous plumage. Actually, at the cost of the birds’ lives: they were simply shot in huge numbers.
Healthy populations were decimated; for some species they never recovered. For others, the great egret among them, the passage of time and the passing of fashions – backed in many cases with conservation programs – have successfully restored the populations. In 1953 theNational Audubon Society, which was formed at least in part to discourage the killing of birds for their feathers, took a decisive step in the cause of the great egret by making the bird the emblem of the organisation.

IT’S STARTED The great winter migration of warblers and their imminent arrival in The Bahamas is underway. Any day now – if not already – the ‘winter’ (in fact autumn & early spring as well) warblers will be arriving on Abaco. There are 38 warbler species recorded for the main island and the cays. For years, it was just 37. Then in 2018 a CANADA WARBLER was seen and photographed by well-known Bahamas birder Chris Johnson. It was a first for Abaco – and the first-ever report for the Bahamas as well. You’ll find the story HERE.
This article is updated from an earlier one written pre-Dorian and the situation will undoubtedly be different now, especially with the transients and rare species. Consider it as a historical record of the prolific warbler species recorded for Abaco and more generally the northern Bahamas before the hurricane struck. The 5 permanent resident warbler are still resident. Many migrants and possibly all transients have sadly not been recorded since, and the rarest perhaps never will be. The hope must be that at least the most common winter warblers will continue to arrive, and in increasing numbers.
First-ever Canada Warbler for Abaco & the entire Bahamas: Aug 2018 (Chris Johnson)
Hooded Warbler, Abaco Bahamas (Chris Johnson)
The guide divides the original 37 species (excluding the Canada warbler) into categories, with a code for each bird to show:
Resident status – permanent / breeding, migratory or transient
Frequency – likelihood of seeing each species in its season, rated from 1 (very likely) to 5 (extreme rarities, maybe recorded only once or twice since c1950 when recording began)
Numerically, the division breaks down into 3 categories of warbler:
5 permanent residents (PR) that breed on Abaco (B), of which two are ENDEMIC
21 winter residents (WR) ranging from ‘everyday’ species to extreme rarities like the very vulnerable Kirtland’s Warbler that needs a specific winter habitat that Abaco can provide
11 transients, most of which you will be very lucky to encounter
Palm Warbler, Abaco Bahamas (Nina Henry)
The photos that follow show an example of each warbler, where possible both (1) male and (2) 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.

West Indian Woodpecker . Abaco . Bahamas (π Keith Salvesen)
The WEST INDIAN WOODPECKER Melanerpes superciliaris is one of Abaco’s specialist birds. Islanders and regular visitors will be familiar with the sight – and indeed the raucous sound – of these beautiful birds. They are commonly found throughout Abaco and the cays. Possibly their rarity across the wider Bahamas is underestimated. The only other island where these birds are found is San Salvador. Formerly resident on Grand Bahama, they are believed to be extirpated there. Abaco is very fortunate to enjoy their noisy company.
