White-headed Starling

Very attractive small tanager of humid tropical lowlands. Found in humid evergreen forest edges, plantations, and gardens; at times with mixed-species feeding flocks of honeycreepers and euphonias. Often in pairs, feeding at all levels in fruiting trees and bushes. Note the short, curved bill. Males are a unique green-blue color with black hood and a banana yellow beak. Female resembles female Red-legged Honeycreeper but is larger, brighter, uniform green, with yellow lower bill and grayish legs.

Not the only blue nuthatch, but the bluest nuthatch. Unmistakable, with a dark head, pale eyering, white throat and breast, and dark-lined pale blue feathers on the wings. Gives quick, sharp, nasal “tzwp” or “tzwit” notes. Clambers up and down tree trunks, often in small parties; frequent member of mixed-species foraging flocks. Favors montane and hilly forests. 

A small gray warbler with a bright yellow throat and eyebrow. All plumages are very similar; immatures are slightly duller and browner. Occurs in pine forests from the southwest U.S. to Nicaragua. Usually stays high in the canopy. Listen for a choppy musical trill, often broken into two parts. Compare with “Audubon’s” Yellow-rumped Warbler, which has yellow on the sides and rump no yellow eyebrow, and yellow restricted to the throat (not breast).
