FIVE STARS: BAHAMAS ENDEMIC BIRDS (FOUR FROM ABACO)

It’s December 2020, and Caribbean endemic birds are, deservedly, being given more time in the sun. Right now they are being featured by BNT (Bahamas National Trust); BirdsCaribbean; and (in an excellent Zoom presentation today) the august Linnean Society in Burlington House, London. So I am chiming in with slightly updated post on the topic, a reminder both of the beauty of the endemics and of their struggle for survival.

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, until quite recently there were thought to be fewer than 300 Orioles left – a barely sustainable number. The species is unsurprisingly IUCN listed as critically endangered. However, there are signs that an intensive conservation program is working, with an increase in individuals and some new local populations found. 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. Here are some striking images of these four endemic bird species taken from the archives for (and starring in) ‘The Birds of Abaco’ published in 2014

‘The Delphi Club Guide to the Birds of Abaco’ was published as limited edition, with additional copies donated to every school and relevant education department on Abaco, and to the conservation organisations. This tied in with the excellent policy of teaching children from a very 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 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’.

COMMON YELLOWTHROATS ON ABACO: CHEERFUL WINTER WARBLERS

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.

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

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…).

ABACO: AN IMPORTANT BIRDING AREA IN THE BAHAMAS

ABACO: AN IMPORTANT BIRDING AREA IN THE BAHAMAS

The Bahamas National Trust BNT is one of several organisations in the Bahamas responsible for conservation across the widely scattered islands of the Bahamas. One of its tasks is to look after the birds and their habitat, and from time to time the Trust publishes articles about their work. The Abaco-related material below is taken from a much longer article by Predensa Moore and Lynn Gape that covers the whole area, and concerns the importance of Abaco as a prime Bird Area. This applies in particular to Little Abaco and the Northern Cays; and to the large area of South Abaco that incorporates the National Park. The bird images used show some Abaco speciality birds mentioned by the BNT in their material.

PHOTOGENIC ENDEMICS: BAHAMA YELLOWTHROATS ON ABACO

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’.

Among the birds we encountered were the endemic Bahama swallows, hairy woodpeckers, red-tailed hawks, kingbirds, red-legged thrushes, red-winged blackbirds, western spindalises, tobacco doves, La Sagra’s flycatchers, crescent-eyed pewees with a nest and eggs, a wonderful ‘booming display’ by antillean nighthawks courting during an early evening fly hatch**… and Bahama yellowthroats Geothlypis rostrata.

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 my iPH@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 it HERE. 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’

Common Nighthawk Photo “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)
