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…
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’
“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)
