Black-throated Blue Warbler in Cerro Azul, a report by Bill Adsett
Today I found a female-plumaged Black-throated Blue Warbler working over a recently fallen tree in the forest adjoining our house at Altos de Cerro Azul. I believe it is an adult female rather than a juvenile; the whitish face markings and the white spot in the primaries were prominent (in fact the latter was somewhat larger than that illustrated in Curson's “New World Warblers”). Remarkably this individual has turned up at the exact spot where we found a striking adult male of this very rare (for Panama) species many years ago (Dodge and Lorna Engleman will remember that). Also of note at the same place today was a group of 5 or 6 Black-eared Wood-Quail; they have been calling on and off around our house for at least a week.
