BLACK-THROATED BLUE WARBLERS ON ABACO

BLACK-THROATED BLUE WARBLERS ON ABACO

It’s warbler time of year on Abaco, and a good time to take a look at the Black-throated blue warbler Setophaga caerulescens. This small warbler has very particular breeding and overwintering ranges. In the summer they are found in the forests and woods of eastern North America. As the Fall approaches, they start to migrate south to the Caribbean and Central America. Abaco is one of their winter homes, as well as a likely transit stop on their way further south. Right now sightings are being reported on the mainland and the Cays.

WHAT DO I LOOK OUT FOR?

Males and females are quite different in appearance (‘sexually dimorphic’), and could even be mistaken for distinct species. Males are a deep slate-blue above (hence caerulescens) with a striking black face and throat, and white underparts. They are unmistakeable, and unlikely to be confused with any other warbler. Females are basically grayish-olive above and pale yellow underneath. For ID, look for a white stripe above the eye, a pale arc below it. In addition, both sexes have a diagnostic white patch on the the wing, that I have seen referred to as a ‘handkerchief‘.**

The legendary bird cartoon website Birdorable, featured often in these pages, as usual has a spot-on comparison of the sexes. TBH, this is a great resource for nailing a bird’s essential characteristics. You should check out its warblers in particular! Here’s their inimitably charming take on the BTBW gender comparison.

These pretty warblers can be seen in gardens, coppice, and woodland. Although mainly insect-eaters, sometimes catching them in flight, they also eat fruit and seeds especially in winter. BTBWs are territorial, and will defend their chosen space against all-comers, including their own species.

WHAT DO I LISTEN OUT FOR?

As I have mentioned before, I tend to find phonetic transcriptions of bird sounds rather baffling – and often not really how I hear them myself. This is especially with the ‘Oh-dear-oh-dear-I’ve-run-out-of-beer’ and ‘Have-a-little-Kalik-at-Pete’s’ kind. One source asserts: “The bird’s song can be described  as a buzzed zee-zee-zeeee with an upward inflection. Its call is a flat ctuk”. You be the judge…

CALL Paul Marvin / Xeno-Canto

BTBW SEX LIFE – ANY GOOD GOSS?

Black-throated blue warblers are – and I say this with considerable reservations – mainly a monogamous species. However it turns out that they have complex patterns of vocalisations and behaviours at breeding time, including very promising-sounding ‘extra-pair copulation’ involving ‘heterospecific cuckoldry’. However, despite all my efforts in researching this phenomenon more thoroughly, merely reading the intricacies quickly crossed my boredom threshold, and my own ‘call’ soon became a ‘sonorous saw-like Zzzzzzzzzzzzzzz‘.  Anyway these birds don’t breed on Abaco so I’ll spare you the details and move on.

 IS MANKIND MASHING UP THEIR HABITAT?

BTBWs are fairly common birds within their range, with a large population. The usual stuff is happening with them in terms of habitat destruction & co at both ends of their migration. For some already threatened species (e.g. Kirtland’s Warblers), habitat degradation at either end of the migration (let alone both) presages a downward spiral in population. With BTBWs, I have read both that the population is decreasing; and in another source, slightly increasing. For now, let’s regard the welfare of the species as being stable. However, the current causes of species decline will doubtless continue, and many regard increasingly evident climate change as being a determining factor for the well-being of migratory species. The birds are not yet out of the woods, so to speak… and maybe never will be.

ABACO’S 37 WARBLER SPECIES: AN ILLUSTRATED GUIDE

ABACO’S 37 WARBLER SPECIES: AN ILLUSTRATED GUIDE

Any day now – if not already – winter warblers will be arriving on Abaco. There are 37 warbler species recorded for the main island and the 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).

The photos that follow show an example of each warbler, where possible (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.

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…

GILPIN POINT, ABACO: A ‘2 HOURS, 40 SPECIES’ BIRDING HOTSPOT

GILPIN POINT, ABACO: A ‘2 HOURS, 40 SPECIES’ BIRDING HOTSPOT

Got  a spare couple of hours? Reluctant to go birding on the bird-reliable yet ambience-lite town dumps, where careful cropping will be needed to avoid including post-apocalyptic scenery in your hard-won photos of a Little Mulligatawny Owl? Then read on. I have mentioned Gilpin Point before as a great place for birding, and listed many of the species to be found there. It benefits from a large pond, a pristine shoreline, and a coppice environment with some pine forest thrown in. All the makings of an excellent birding location, with suitable habitat for a wide variety of species. Blue-winged Teal, Abaco (Keith Salvesen)

On November 21st Reg Patterson, well-known Abaco birder and guide, was up early, and by 07.00 he was at Gilpin Pond where  he spent a couple of hours . He recorded 40 species in that time, from very large to very small. His checklist reveals a great cross-section of the birdlife to be found on Abaco. There might easily have been parrots there too, since Gilpin has become one of their daily chattering spots for a frank exchange of news and views. Sadly it seems that the beautiful and (now) rare SPOONBILL recorded there in early October has moved on.

Willet, Abaco

Here is Reg’s checklist, which I have illustrated with a variety of photos of the species he found, all taken on Abaco and many actually taken at Gilpin Point. There are plenty of other species that might easily have been seen there then – or perhaps later in the day (e.g. snowy egret, yellowlegs, kestrel, turkey vulture, red-legged thrush, cuban emerald, not to mention shorebirds and seabirds if some time was spent on the shore).

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.
