Gray-headed Tanager

Nest parasite that lays its eggs in the nests of Peters’s Twinspot. Breeding males are glossy greenish-black, and in good light may show a paler gray wash across the head and breast. Females and non-breeding males are streaky and brown on the back, with a bold facial pattern and pale underparts with gray across the breast. The bill is whitish and the legs pale red. Found along forest edge, and in cultivation and moist woodland. The song is a fast mix of scolding and squeaky notes, often mixed with imitations of the vocalizations of its host twinspot: a fast, silvery trill. Similar to other indigobirds, but breeding male separated by its greenish gloss and all-black wings. Non-breeding male and female can be tentatively identified by the gray wash across the breast.

Striking small game bird of heavily forested hills and mountains. Typically shy and difficult to see in the dark understory, but its loud, haunting song carries across long distances. This species has a prominent white necklace, but its orange throat, blueish-gray belly, and bright wing stripes are often more visible from a distance.

Small understory antwren. Males are dark gray with an extensive black throat (extending farther down than in Long-winged Antwren); females are tan below, gray above. Both sexes have white wing spots; this is an especially helpful feature in identifying females. Found in areas of tangled understory in mature rainforest; largely restricted to bamboo patches in areas with bamboo. Usually rarer than the similar Long-winged Antwren, and differs in voice; its song is a slow series of punctuated downslurred whistles “pew, pew, pew, pew, . . .” unlike the high wheezy song of Long-winged Antwren.
