The Bahama Yellowthroat Geothlypis rostrata is one of 5 bird species endemic to the Bahamas. Three other endemics found on Abaco are the Bahama Woodstar,Bahama WarblerandBahama Swallow. The fifth is the endangeredBahama Oriole, now only found in very small numbers on Andros. They once lived on Abaco, but are unrecorded there since the 1990s and are considered extirpated. You can find out more about all these endemic birds together in a nest HERE.
I’m fond of these birds with their striking Zorro masks. It is one of the few species that I am able to imitate with sufficient accuracy to draw one out of the coppice. Their call is usually described as a ‘wichety-wichety‘. I realise that the talent to mimic it has no other use in life. Here’s a short recording I made – the Yellowthroat is the first and last call of the sample, with other species in between.

I was looking at the list of the dozens of Abaco bird species I have featured over the years, when I was struck by the complete omission of one of Abaco’s most significant small birds – the Bahama Warbler Setophaga flavescens. This warbler species is of the most important in the Bahamas for several reasons, any one of which should have prompted me to showcase this lovely bird before now.
A SPECIALITY BIRD
The Bahama warbler is a significant species with a near-unique status in the Bahamas:
One of only 5 permanent year-round resident warblers (33 others are migratory), the other 3 being the OLIVE-CAPPED, YELLOW, and PINE warblers.
Until 2011, the BAWA was classified as a subspecies of the YELLOW-THROATED WARBLER. The ornithological powers-that-be then recognised that the two species were distinct in both appearance and in vocalisation, and split them into separate species (this splitting / amalgamating process occurs annually and plays havoc with the precious ‘Life Lists’ kept with such rigour by ardent birders**.
The BAWA has such a confined range that even the extensive reach of the wonderful Cornell Lab of Ornithology has not got as far as this bird. The info sections of the otherwise comprehensive website for Neotropical Birds are blank and waiting for someone to upload some details. Here are a few facts in one of a very good series of info-graphics produced by the BAHAMAS NATIONAL TRUST.
** I have never even started a Life List, which demonstrates just how lightweight I am as a bird person

ABACO’S 38 WARBLERS: AN ILLUSTRATED ID GUIDE (Pt 1)
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’ / ‘Fall’ (late summer & 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. Exactly a year ago, a CANADA WARBLER was seen and photographed by well-known 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.
First-ever Canada Warbler for Abaco & the entire Bahamas: Aug 2018 (Chris Johnson)
This post is the first of 3 warbler posts for the Fall. A while back I compiled a basic (in retrospect) guide to Abaco’s warbler species. I’ll give a link and pdf in due course once I have rechecked (improved? rewritten?) it. [Note: of no value on eBay, @m@z@n or anywhere else]. Many of the warblers are far from easy to distinguish from each other. For example, many males have yellow or yellow-and-black plumage. The females are invariably less colourful – often brownish or olive – than the males (as are juveniles), and that can lead to confusion – and not only by me, I think.
Hooded Warbler, Abaco Bahamas (Chris Johnson)
The guide divides the original 37 species into categories, with a code for each bird to show. You’ll see below the codes relating to each of the 5 resident species:
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 once or twice since c1950
Numerically, the division of the 38 breaks down into 3 categories:
5 permanent residents (PR) that breed on Abaco (B), of which two are ENDEMIC
21 winter residents (WR) ranging from ‘everyday’ species to rarities like the rare, vulnerable Kirtland’s Warbler (now under threat from proposed development)
12 transients, most of which you will be very lucky to encounter
Palm Warbler, Abaco Bahamas (Nina Henry)
The photos used in this series were almost all taken on Abaco / the Cays. There’ll be examples of the male of each warbler species, with some females for contrast. Where I have no Abaco / Baha images – especially with the transients – I have used other mainstream birding resources and Wiki. All due credits will be given at the foot of each post.
The warblers shown above are a mix of warbler species on Abaco: resident / endemic, winter migrants, and transient / vagrant. Time to take a look at the first category, the Bahamas-loving resident species that live and breed on Abaco

ABACO WARBLERS: THE FAMOUS 5 (PERMANENT RESIDENTS)
There are 37 warbler species recorded for Abaco. They fall into three distinct categories. Surprisingly perhaps, only 5 species are permanently resident on Abaco, ie non-migratory. Then there are warblers that commute from the breeding grounds of North America to warmer climes in the Fall, returning in the Spring to breed. Some will be familiar – PALM WARBLER, AMERICAN REDSTART, BLACK-AND -WHITE WARBLER. Others, like the HOODED WARBLER, are less common. One or two are very rare indeed, such as the KIRTLAND’S WARBLERSthat choose Abaco as a winter destination. Finally there are the so-called transients, warbler species that use the northern Bahamas as a stopover during their longer migratory flights, such as the BLACKPOLL WARBLER.
The 5 permanent residents obviously don’t migrate, so there is a chance to find them throughout the year. The pine forests would generally be the best place to start the quest. Importantly, 2 of the 5 species are endemic birds to the Bahamas and can be found nowhere else: BAHAMA YELLOWTHROAT and BAHAMA WARBLER. The latter and the OLIVE-CAPPED WARBLER, are very range-restricted, and only found on Abaco and Grand Bahama.

CHECKLIST CODESbased 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
RARE, PRECIOUS – AND FOUND ONLY ON ANDROS, BAHAMAS
The future of the gorgeous endemic Bahama Oriole (Icterus northropi) hangs in the balance. IUCN Red Listed as ‘Critically Endangered’, the Oriole once lived on both Abaco and Andros. As recently as the 1990s, the species became extirpated on Abaco, leaving a small and fragile population in fairly specific areas of Andros. These are places where the habitat is conducive to the orioles’ well-being, and in particular where they can safely breed and (with luck) replenish their depleted population.
We hear a lot about habitat loss as a grave worldwide problem for an increasing number of species. Narrow that down to one species, one island, a few defined areas, then add mankind and his needs to the mix. The wrong mix of habitat degradation, clearances, predation or disease could cause the Andros population to disappear as well.
Which is where conservation and science come into play. The Bahamas archipelago benefits from an astonishing number of (broadly-speaking) environmental organisations that are involved in species and habitat protection, both terrestrial and marine. They range from international to Bahamas-wide and Governmental, to NFP organisations on the main islands, and on through local communities via citizen scientists to dedicated individuals. All are fighting a specific battle with a single aim; all face an increasing array of metaphorical weapons being deployed against them.
SO, ANY GOOD NEWS THEN?
Returning to the orioles – in many ways a perfect indicator bird species – recent research has led to an encouraging discovery. A new study in The Journal of Caribbean Ornithology published by researchers from the University of Maryland, Baltimore County and Bahamas National Trust collaborating on the Bahama Oriole Project (@BahamaOrioleProject) reveals new evidence about the nesting habits and habitats of the orioles that will have “…major implications for future conservation” (this work was funded in part by the American Bird Conservancy and Birds Caribbean).
The study is the outcome of the work of a dozen conservation specialists. In a coconut-shell, the orioles were thought to nest only in the coconut palms found near the coast. However the recent intensive research program reveals that ‘multiple pairs’ breed in the pines and the thatch palms of the forests, away from the coast. Indeed, these may prove to be the primary nesting locations. The implications of these new findings are significant, not least for a possible uplift in numbers and the way in which conservation measures can be adapted to the new discovery. For those wanting something more authoritative, the short Abstract of the study is given at the end. And if you’d like to read the whole article, click on the link below.

Disease within the population is also cited as a contributory cause
*The date of this arrival seems to correspond to when the orioles were extirpated from Abaco. However, see next para.
WHEN & WHY DID THE ORIOLES 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”. However, Abaco birding expert Elwood ‘Woody’ Bracey comments (see below) that Bahama Orioles were last formally recorded on Abaco in 1973 by researcher Duncan Everette and his partner who were banding warblers in Southern Abaco in what is now the Abaco National Park. At that time, the Shiny Cowbird was only rarely found on Abaco, if at all.
I’ve found no clear clue as to the cause – nor even when the last evidences sighting of an oriole on Abaco was made. I haven’t found a single photo of one taken on Abaco at any time in history. To be fair the option of snapping everything with wings multiple times using a digital camera with a huge chip didn’t exist then. As to past history, Kevin Omland of @BahamaOrioleProject says that there are at least 9 specimens in museums around the world collected from Abaco in the 1800s and early 1900s.

The Bahama Oriole (Icterus northropi) is a Critically Endangered species endemic to The Bahamas and currently found only on the Andros island complex. With the elevation of the Bahama Oriole to full species status in 2011, research suggested that there were fewer than 300 individuals remaining in the global population. The Bahama Oriole was also termed a “synanthropic species” based on data suggesting that the species nested almost exclusively within anthropogenic residential and agricultural habitats in introduced coconut palms (Cocos nucifera). These conclusions were based on population surveys primarily confined to settled areas near the coasts. However, we documented multiple pairs of orioles with breeding territories deep in pine forests, and we present the first records of Bahama Orioles nesting in pine forests—in both a Caribbean pine (Pinus caribaea) and native understory Key thatch palms (Leucothrinax morrisii). Given the predominance of the pine forests on Andros, this newly documented breeding habitat has important implications for developing population estimates and future conservation plans for the Bahama Oriole.

Yesterday an Abaco friend asked me to ID a striking-looking bird photographed in the coppice by their house. It was a Bahama Yellowthroat, one of the 5 bird species endemic to the Bahamas. The bird was not clear enough for use here, but I’ll take any reason to feature these lovely creatures, with their trademark Zorro masks.
The other endemics are the Bahama Woodstar, Bahama Warbler and Bahama Swallow – all found on Abaco. The fifth is the endangered Bahama Oriole. Sadly these fine birds are now only found in very small numbers on Andros. They once lived on Abaco too, but have not been recorded there since the 1990s, and are considered extirpated. You can find out more about all these endemic birds HERE.
The Bahama Yellowthroats have a cousin, the Common Yellowthroat, that is a winter visitor on Abaco. There is some scope for confusion between the two birds, although a close look will reveal several differences. But let’s not get into that kind of detail right now… it would slightly detract from this little ‘gallery of gorgeous’.
One reason for my fondness for the yellowthroats is that it is one of the few species that I am able to imitate with sufficient accuracy to draw one from the depths of the coppice to the front of stage. It’s usually described as a ‘wichety-wichety‘ call, and the talent to mimic it has no other uses in life. Here’s a short recording I made – the Yellowthroat is the first and last call of the sample, with other species in between.
These are curious birds, and are not afraid to pose for a while, watching the watcher. They are also very vocal birds. You’ll see that many of these photos show them singing (‘vocalising’). You can even see their tiny tongues!
A couple of these images feature in THE BIRDS OF ABACO. This is a good moment to mention that we still have some remaining books, and right now we have a seasonal offer on them of a festive $88 plus shipping. A drop in MH can be arranged. Interested? Let me know or email the Delphi Club direct at firstname.lastname@example.org

This is a slightly revised version of a guide I posted a couple of years ago. Afterwards, I compressed the guide into a pdf which, in theory at least, is downloadable. You could even send it to your phone and add it to your home screen, so that you will never be without a basic guide to the warblers around you. But it’s not as enthralling as Pokemon Go!, I do quite understand…
THE CARIBBEAN ENDEMIC BIRD FESTIVAL (CEBF) is a Caribbean-wide festival that aims to heighten awareness for birds generally in the region. It is sponsored by the excellent BIRDS CARIBBEANorganisation – click the link to see what it is all about. Birds, obviously, but from the points of view both of promoting and of preserving the rich avian variety throughout the Caribbean.
As part of the CEBF celebrations this month, a birding group from New Providence came to Abaco to explore the birdlife. The expedition group included several well-known local bird experts, all the better for locating and identifying species and ensuring a comprehensive checklist could be compiled. Also in the group was photographer Linda Huber, whose photos you will undoubtedly have seen in Bahamas publications, including the recently published small guideBEAUTIFUL BAHAMA BIRDS(click to see my review and further details – highly recommended for any birder from novice up). Here are a few of Linda’s photos of some of the birds seen during the expedition, a gallery that shows the extraordinary diversity of species to found in a short time on Abaco.
Apologies to those who received a ‘false start’ draft of this post. It was lunchtime, I was hungry, I pressed ‘Save Draft’… or thought I had. Why is the ‘Publish’ button so close? Oh. Right. I see. It’s not its fault, it’s mine…

The debatable ‘Caribbean Coot’, about which it has been written** The American Coot is familiar to all, but controversy surrounds the Caribbean Coot with its all-white frontal shield. Some authorities say it is a separate species; others say it is a true subspecies of the American Coot; some claim it is simply a local variant. Bond (1947) treats them as distinct species. The image below shows the two species together. They coexist contentedly and are indifferent to the debate.

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.
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).
“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…

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’S ENDEMIC BIRDS: MAKING A CASE FOR PROTECTION
I recently wrote a post showcasing the 4 Bahamas endemic bird species found on Abaco: swallow, warbler, woodstar hummingbird, and yellowthroat. You can read it and see some great photosHERE. Sadly, the magnificent oriole, extant on Abaco for centuries, was extirpated in the 1990s. You can still see them but only on Andros; and the population there is barely sustainable – there are only 260 remaining. Still, on Abaco there remain four of the endemic species to conserve and care for.
The Bahamas National TrustBNThas produced 6 brief but informative illustrated ‘cards’ about the Bahamas endemics. They deserve a wide audience, especially in view of the threats to some species for reasons that include habitat loss and increasing development. New Providence lost its subspecies of Bahama Yellowthroat within the last 20 years. Let’s hope that Abaco can hold onto its speciality birds for the future.
FIVE STARS: BAHAMAS ENDEMIC BIRDS (FOUR FROM ABACO)
The Caribbean Endemic Bird Festival is underway. You can find out more on the CARIBBEAN BIRDS FESTIVALSFacebook page. Abaco is fortunate to be home to 4 of the 5 endemic Bahamas species. The fifth, the beautiful BAHAMA ORIOLE Icterus northropi, was found on both Abaco and Andros until the 1990s, when it sadly became extirpated from Abaco. Now found only on Andros, there are thought to be fewer than 300 Orioles left – a barely sustainable number. The species is unsurprisingly IUCN listed as critically endangered. Here’s a picture of one as a reminder of what Abaco is now missing…
Abaco’s four endemic species are the tiny Bahama Woodstar hummingbird, the Bahama Yellowthroat, the Bahama Warbler (since 2011), and the Bahama Swallow. All are of course permanent breeding residents on Abaco and its outer Cays. None is exclusive to Abaco; all are relatively plentiful. The Woodstar is perhaps the hardest to find, not least because it competes territorially with the Cuban Emerald hummingbird. Even Woodstars can be found easily in some areas – Man-o-War Cay is a good place for them, for example. Here are some striking images of these four endemic bird species taken from the archives for “The Birds of Abaco” published last month.

“The Delphi Club Guide to the Birds of Abaco” was published as limited edition of 500 and has only been for sale for 8 weeks or so exclusively through the Delphi Club. Yesterday, we passed a happy milestone in that short time as the 250th copy was sold. Complimentary copies have also been donated to every school and relevant education department on Abaco to tie in with the excellent policy of teaching children from an early age the value of the natural world around them, the importance of its ecology, and the need for its conservation. The cover bird for the book was easy to choose – it just had to be a male Woodstar in all his glory with his splendid purple ‘gorget’.

The Least Tern in the header image was a stroke of luck. I was watching plovers on the beach when it landed on the tideline with a small fish in its mouth. I just had time to point the camera and fire off 3 shots before it flew off again. This was the only usable image. I liked the fish, of course, and the way its little legs made a dent in the wet sand.
This Black-necked Stilt was attempting to distract me from a nearby nest, which I’d have known nothing about until it tried to distract me. It zig-zagged towards me, striding through the water while yelling, and then took off and flew at my head! Twice. I moved away…

The Bahama Yellowthroat is one of 4 endemic species on Abaco. Only the males have the striking Zorro mask. They are shy birds, but also inquisitive. I learnt to imitate their call (not difficult) to bring them out of scrub and bushes. Once out, they liked to take a good look from a safe distance.
PHOTOGENIC ENDEMICS: BAHAMA YELLOWTHROATS ON ABACO
I’ve been keeping this little bird up my capacious avian-friendly sleeve for a while. In June we took a truck and headed for deep backcountry to the edge of the pine forests and beyond to see what we could find in the way of birdlife. Good choice – the answer was ‘plenty’.
The illustrative photos are of poor quality, but rather than blame my camera (as I am only too ready to do), I plead ‘overexcitement’ in mitigation. Of the 4 endemic species on Abaco, this was the only one I’d never seen. There was a tweeting noise on the edge of an abandoned sugar cane field (above), followed by some rustling… and out fluttered this bird, crossing the track right by us and landing quite close to inspect us.
This striking bird, with its Zorro mask and bright yellow body, is an endearing mix of shy and inquisitive. Only the males have the mask – the females are less colourful, though naturally equally interesting…
Yellowthroats are responsive to pishing, and once lured from cover they may happily remain on low-to-medium height branches or on a shrub, watching you watching them.
Their song is quite easily imitated, and that may also bring them into the open – a source of immense satisfaction to the amateur (me) if it works. Here’s an example, courtesy of myiPH@NE METHOD for bird recording. It’s the call at the start and the end.
The one we watched had plenty to sing about – it’s just a shame that my images are so poor, because in some you can see its tiny tongue. A bit too blurry, though, even by my own moderate standards for inclusion.
At a formative stage of this blog, I did a short post about the endemic Bahama Yellowthroat and its comparisons with the similar and better-known Common Yellowthroat, which is also found in the Bahamas. You can read itHERE. There’s a female shown, a video, and an unacknowledged debt to Wiki or similar source, I can’t help but notice…
**ANTILLEAN NIGHTHAWKS AND THE ‘BOOMING DISPLAY’
“On summer evenings, keep an eye and an ear out for the male Nighthawk’s dramatic “booming” display flight. Flying at a height slightly above the treetops, he abruptly dives for the ground. As he peels out of his dive (sometimes just a few meters from the ground) he flexes his wings downward, and the air rushing across his wingtips makes a deep booming or whooshing sound, as if a racecar has just passed by. The dives may be directed at females, territorial intruders, and even people.” We found ourselves right in the middle of one of these astounding displays, with maybe 100 birds behaving exactly as described, often whooshing within inches of our heads. I’ll post some more about it in due course. Credits: Philip Simmons; All About Birds (Cornell Lab)
Q: WHAT IS CUTER THAN A BAHAMA WOODSTAR HUMMINGBIRD ON ABACO?
A: A BABY BAHAMA WOODSTAR HUMMINGBIRD ON ABACO
Charmaine Albury from Man-o-War Cay, Abaco, has taken some fabulous photographs of a nesting Bahama Woodstar Hummingbird at her home. With her kind permission, I am delighted to display a selection of them below. The adult is a female, and lacks the striking purple gorget of the male. The baby’s plumage is… spiky! The cup nest is beautifully constructed, made from plant down, bark and cobwebs, balanced in a string of lights. The size of the bulbs give a very clear idea how tiny these sweet little birds are. These are photos to be viewed in wonderment and awwwwwwwwww….
This hummingbird species nests all year round. The female lays 2 elliptical white eggs, which she incubates for 15–18 days. Not only is the baby in these pictures in a very small nest, it is sharing it with an unhatched and presumably sterile egg. Then again, two babies would be even more of a squash…
The Bahama Woodstar Calliphlox evelynae is endemic to the Bahamas, found only on there and as an occasional vagrant in south east Florida. On Abaco, it is one of four endemic species found on the island – the others are the Bahama Swallow, the Bahama Warbler and the Bahama Yellowthroat. Together with the unique ground-nesting ABACO PARROT, these are among the most special birds of Abaco.
A BIRDER’S GUIDE TO THE BAHAMA ISLANDS (INCLUDING TURKS & CAICOS)
ABA BIRDFINDING GUIDES (American Birding Association)
Anthony W. White
QUICK REVIEW In a rush? Scroll down for a 30-second bullet-point review. If not, hang in here for fuller details…
PUBLISHER’S BLURB (précis)The first comprehensive guide to finding birds on the islands of The Bahamas and TCI. The islands host an unusual mix of Caribbean and North American species, with over 300 bird species recorded. There are 3 endemic species: Bahama Woodstar, Bahama Swallow, and Bahama Yellowthroat, and a host of other specialties, including such birds as West Indian Whistling-Duck, White-cheeked Pintail, Key West Quail-Dove, Great Lizard-Cuckoo, Cuban Emerald, West Indian Woodpecker, Bahama Mockingbird, Olive-capped Warbler, Stripe-headed Tanager, Greater Antillean Bullfinch, and Black-cowled Oriole. Seabird nesting colonies [include] Audubon’s Shearwaters, White-tailed Tropicbirds, and 8 tern species. The parks and refuges of The Bahamas and TCI protect a great diversity of subtropical birds, among them the Bahama Parrot (an endemic subspecies of Cuban Parrot), and many North American wintering birds, including the endangered Kirtland’s Warbler. The New World’s largest flamingo colony nests on Great Inagua, protected by the country’s largest national park. The Guide [includes] complete descriptions by Tony White of more than 150 birding sites on the major islands and smaller cays. It also features a beautiful eight-page Photo Gallery of many of the Bahamian specialty birds, several of which show up regularly in Florida
RH VIEW This book obviously covers a far greater area than Abaco / Northern Bahamas – indeed, it is about as comprehensive of the whole Bahamas region as it could get. Where it scores highly is in taking the area island by island, cay by cay, and identifying the prime birding areas on each. I have to say that, being a 1998 book, some of the descriptions of places on Abaco that I am familiar with are not as you will find them now; and doubtless this applies across the whole region. As the Table of Contents shows, the book is split into ‘places’ chapters, with additional and useful general information chapters. Abaco is covered in just 20 pages. It’s not a lot, but the birding hotspots are well covered, and expected / hoped for bird species are given for each.
Despite the relatively little page space given to each region, there is much else to be got from this book. The final third of the book includes a detailed annotated list of the speciality bird species (also shown in photo gallery format earlier in the book). This is followed by a huge 20-page bird checklist, with every species given a numbered code for each region, ranging from 1 (easily found) to 6 (cannot be found – extinct or extirpated). So you will find, for example, that a Forster’s Tern is rated ‘4’ for Abaco – ‘extremely difficult to find’. There are short notes on other Bahamas wildlife, divided into mammals, reptiles, amphibians and insects – followed by helpful appendices (a glossary; a list of common name alternatives); a massive 22-page bibliography; and a serviceable index
The chart inside the front cover shows where the specialty Bahamas birds are to be found . At the back is a large area map showing the total coverage
BULLET POINT REVIEW FOR THOSE WHO ARE PRESSED FOR TIME
Fairly weighty 300 pages covering the entire Bahamas region
Short but helpful descriptions of birding hotspots on the islands and cays, with the species you may encounter
Excellent ancillary species and distribution checklists
Focus on specialty birds of the Bahamas
Particularly useful for anyone investigating different regions of the Bahamas, or wishing to compare them
14 years since publication is a long time in the islands’ development; expect some irrelevant references for 2012
Overall a useful, interesting bird location book, but NB not intended as species identification field guide
ABACO HUMMINGBIRDS: BAHAMA WOODSTAR & CUBAN EMERALD SIGHTINGS MAP
A while ago a new feature landed near the end of the right-hand sidebar. The idea was to put together an informal mapping of Woodstar and Emerald sightings on Abaco.
I put a few in as a start, hoping for more contributions, but so far it hasn’t been a popular item. Maybe it won’t work at all as a contributory feature, or maybe it just isn’t interesting if you live with the hummers. As an Abaco visitor (never having seen a hummingbird before. Except stuffed ones) they are a delight. A highlight.
It’s worth another try, and I have revised the map slightly to make the two contribution / contact methods clearer. It can’t be made more interactive than that I’m afraid. If you go to the sidebar and click on ‘View larger map’, you’ll see the data in more detail.
The map might even test the theory that Woodstars are scarce where Emeralds are numerous.
If you’d like to add to the mapping, I just need the type of hummer; the location in reasonable detail so I can stick a pin in the map; month / year (e.g. 03/12) and I will do the rest…
THE BAHAMA SWALLOW: A SMALL ENDEMIC BIRD WITH BIG SURVIVAL PROBLEMS
The IUCN (International Union for Conservation of Nature) RED LISTstatus of the endemic Bahama Swallow Tachycineta cyaneoviridis has been upgraded from ‘Threatened’ to ‘Endangered’ because its small declining population faces a number of threats that are likely to worsen in the future. In particular, renewed logging activity and widespread property development could result in a further decline in breeding habitat.
The excellent photo above is the ‘Wikimedia poster bird’, but was in fact taken by prolific bird photographer Craig Nash in the main driveway of the Delphi Club, Abaco in 2010. He blogs as Peregrine’s Blog – see RECOMMENDED LINKS in right sidebar
This swallow species breeds only on 4 Bahamas islands: Grand Bahama, Abaco and Andros; and on New Providence, where a few birds are seen each breeding season, suggesting a ‘relict’ population there. The map below suggests that confirmed numbers are so few that New Providence sadly no longer counts as an ‘official’ breeding island.
The Bahama Swallow winters throughout the Bahamas and has been recorded as far as eastern Cuba, but in general the full wintering range is little known. It is a rare vagrant elsewhere during migration, including Florida. The preferred habitat is in the pine forests, where they nest in old woodpecker holes in Caribbean Pines using pine needles, Casuarina twigs, and grass to make the nest which they line with feathers. They typically lay 3 eggs. Incubation is 15 days and the fledging period is around 22 days.
Besides loss of habitat due to human intervention, other factors in population decline are thought to relate to hurricanes and forest fires. The Red List proposals for conservation of the Bahamas Swallow state:“Survey all suitable breeding habitat and assess the status of the species and its habitat; Gather empirical evidence to clarify population trends as a priority; Assess winter distribution and habitat requirements; Study the impacts of fire suppression on the species; Maintain natural nest-sites through a pine snag management programme, and potentially fire management; Assess and monitor the success of the nest box scheme; Protect remaining forest in the Bahamas and minimise the area lost to housing development and logging; Assess the impact of starling and house sparrows on the population and develop appropriate measures to reduce the threat”
The Bahama Swallow has joined other notable bahamian wildlife species in receiving the accolade of a stamp and a coin:
The Bahama Yellowthroat (Geothlypis rostrata) is a resident breeder species of warbler endemic to the Bahamas, closely related to the migratory Common Yellowthroat. The other birds endemic to Abaco / Bahamas are the Bahama Swallow, BAHAMA WOODSTAR and ABACO PARROT
HABITAT Dense low scrub, usually in drier areas than used by wintering Common Yellowthroats. It builds a cup nest low in dense vegetation and lays two eggs. Like other yellowthroats it feeds on insects and other small invertebrates in low vegetation
THE 3 VARIETIES The adult Bahama Yellowthroat is 15 cm long with a large bill. There are 3 subspecies: G. r. rostrata on Andros and New Providence islands (uncommon to rare); G. r. tanneri on Grand Bahama, Great Abaco and associated islands (common); and G. r. coryi on Eleuthera and Cat islands (common). The noticeable distinction between these 3 types seems to be in the forecrown colour (not one I myself would readily spot…)
DIFFERENCES FROM COMMON YELLOWTHROAT The Bahama Yellowthroat is slightly larger than wintering Common Yellowthroat and has a heavier bill and ‘slower, more deliberate movements’. Males have ‘more extensively yellow underparts, a larger facemask extending onto the nape, and in the case of coryi the distinctive yellow forecrown. Females have a grey wash to the head not shown by Common Yellowthroat’.
SONG Described as a loud wichety wichety wichety wich, similar to that of Common Yellowthroat, with the call a softer jip than that of Common Yellowthroat. This is meaningless to me – lots of warblery birds sound like that as far as I can make out. Here is a very short recording of a BY on Abaco courtesy of Xeno-Canto, but it’s not saying wichety to me – more like whee-hew
Below is a short self-crediting video to illustrate the song of a Bahama Yellowthroat on Grand Cayman. There’s a hint of wichety there.
CONSERVATION The Bahama Yellowthroat population overall is quite small and is outnumbered in winter by migrant Common Yellowthroats. It appears not to be endangered. Its conservation is currently listed as ‘Least Concern’ (see Wiki-Box above). The population may be decreasing slightly due to habitat destruction, but not yet sufficiently to bring the species within the ‘vulnerable’ classification.
Here is an excellent clear image of an adult male by Craig Nash who has taken many wonderful photos around Delphi and further afield – see the 4 ‘Peregrine’s Blog’ links under the Blogroll in the SIDEBAR Highly recommended.
