Bell's Vireo 5-20091023
Medium-sized vireo with rather substantial bill, faint spectacles with white lores, gray head that contrasts with olive back, white chin, yellow on breast most prominent on flanks, one prominent white wing bar, but also faint second bar. No vocalizations. no tail-pumping as in Bell's Vireo, but the bird was very active, foraging in a small tree. Bell's Vireo has a "light bill," per Sibley. The upper mandible of this bird's bill is light brown, and the lower mandible is very pale. My best guess was a first year White-eyed Vireo (assuming that juvenile might not have yellow in front of eye), but I could not find any good illustrations of their plumage. Pranty's book does not even mention Bell's Vireo as occurring in Florida, while Brian Rapoza's book lists it as a western vagrant that shows up nearly every year.
