OUR QUIZ BIRD
Let’s look at the Warbler Guide Finders to narrow this one down. There are a number of birds with yellow in them…let’s see if there are any other features we can find that will help us narrow it down.
THE FINDERS SHOW A NUMBER OF YELLOW BIRDS – WHAT ELSE CAN WE LOOK FOR?
Let’s work from head to tail … on the head we see a pronounced supercillium (eyebrow)…that should be helpful! There’s a tinge of brown on the crown, too. The upperparts of the back are brownish – and look at those wings…there are wingbars but they’re brown, which might be another useful point. The underparts are patchy yellow, and the rump and undertail are yellow (brighter in the undertail).
SOME USEFUL MARKS INCLUDE A WIDE SUPERCILLIUM, BROWN IN THE CROWN AND WINGS, BROWNISH WING BARS, PATCHY YELLOW IN THE BODY, AND A YELLOW RUMP AND UNDERTAIL.
So let’s look again at the finders…there really aren’t that many birds that are drabish yellow with a strong supercillium. I see Palm, Prairie, Hooded, Tennessee, Orange-crowned, Blackburnian, Worm-eating, Swainsons, Blackpoll, and Yellow-rumped (Myrtle). Out of those, which have yellow in the body or undertail? Just Palm, Prairie, Hooded, Orange-crowned and maybe Blackpoll. Great! We’re really narrowing it down now.
ONLY A FEW SPECIES HAVE A SUPERCILLIUM AND ARE DRABISH-YELLOW LIKE OUR QUIZ BIRD.
Here’s something else, though…what about those brown wingbars? And the yellow upper and undertail? Really, that only looks like Palm as far as I can see. If I go to the Palm Warbler account, I see that in fact those are a unique combo…and combined with tail-pumping, this looks like a really good match.
OUR PALM WARBLER COMPARISON PAGE CONFIRMS THE ID.
The only thing close is Prairie…but look how the wingabars are yellow, not brown, the streaking is black as opposed to reddish-brown, and the Prairie has a distinct facial pattern that is different from Palm. It is, in fact, a fall Palm Warbler. These birds are often seen feeding on the ground, and also in small flocks. Their continuous tail-pumping is a great tip-off, too, and although there are some other tail-pumping warblers (the Waterthrushes, Magnolia, Prairie and Kirtland). the flocking, yellow undertail and rump, brownish wingbars (and often crown) and sometimes brown breast streaks are all separators.
