Identification
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.
