Identificación
A forest-dwelling cuckooshrike in which males and females are strikingly different. Males are entirely black with a greenish gloss. Females have a barred olive-green back, a whitish throat, and otherwise pale yellow underparts with some barring on the breast. Found in the canopy of various forest types, including gallery forest, lowland rainforest, and montane forest. Not very vocal, but the most frequent vocalizations are thin, high-pitched “seep” notes. The male resembles other black male cuckooshrikes, but is distinguished by the slightly larger patch of bare yellow skin on the mouth and the greenish gloss, though these can be hard to judge. The female is identified by its combination of a barred olive back and a lightly barred yellow breast.
