YELLOW WARBLERS ON ABACO
Of the 37 WARBLER SPECIES recorded for Abaco, 25 are mainly or partly yellow. So talk of a ‘yellow warbler’ can as easily be a general description matching any one of a number of species, as a particular description of the one and only Yellow Warbler Setophaga petechia. This small sunny bird is a common permanent resident on Abaco, one of only 5 resident warblers. The other 4 don’t help the situation much, by dint of all being yellow to a greater or lesser extent.
My general rule of thumb is that the Yellow Warbler out-yellows all the rest (though the winter-resident PROTHONOTARY gives it a run for its money), with the adult males bright and cheerful all over and the females rather less glaring but still demonstrably yellow from beak to tail tip.
Q. ARE THEY ALWAYS EASY TO SEE? A. SEE BELOW, GO FIGURE
Q. CAN YOU SHOW MORE PRETTY FEMALES? A. BY ALL MEANS
Q. SO YEWAs ARE COMMON? HAVE YOU EVER PHOTOGRAPHED ONE? A. ONLY HOPELESSLY
Q. DO THEY HAVE AN ATTITUDE PROBLEM? A. ONLY VERY RARELY
A THREAT TO THE SPECIES Shiny Cowbirds, luckily still rare on Abaco, favour yellow warbler nests for their parasitic egg-laying, with sadly predictable results. These cowbirds properly belong in South America, but they are gradually spreading north through the Caribbean, and have now reached Florida. I’m beginning to take a (purely personal) hard line on invasive species where they diminish and destroy indigenous species: eradication. The feral peacocks of Casuarina, now several generations down the line from their original introduction as exotic pets, do no harm and are undeniably decorative. But would you prefer the pretty yellow warbler and its fledglings in your garden, or the shiny cowbird that displaced them?

And finally… the song that out-yellows all other songs with the word ‘yellow’ in the title – it is the only song called just that one word!
