Ashy-headed Tyrannulet

Impressive dark falcon, with broad shoulders, feathered legs, and long, pointed wings. Favors open environments, where it is an aggressive aerial hunter, frequently observed in rapid pursuit of birds. Often confused with darker individuals of Brown Falcon, a species with larger, blocky head, unfeathered legs, less pointed wings, and more pronounced tear-drop mark below the eye.

A small Hawaiian honeycreeper of native forests above 5,000 feet elevation on eastern Maui. Occurs in non-native forest at Poli-Poli. Males are bright yellow and females and immatures are greenish gray with some yellow on the face. The bill is straighter than in amakihis. Forages rapidly on branches and twigs. Often seen in small flocks. The song is a varied warble and the call is a sharp “chick.” Sometimes responds to squeaking and pishing.

Antvireos, as the name, suggests, resemble vireos, with rather heavy bills and shortish tails. This species inhabits open understory in humid forest of tropical lowlands and foothills. Usually found as sluggish singles or pairs, at times moving with mixed-species feeding flocks. Male has gray face and breast with a broad dark mask. Female has rusty cap and plain face and breast with a whitish eyering.
