Identification
A large antshrike with a spiky crest, an often partially concealed white wingbar, and a white-tipped tail. Males are entirely glossy black while females have a chestnut crest. Inhabits the understory of seasonally and permanently flooded forest with vine tangles and dense thickets, where its far-carrying song, an accelerating series of “tah” notes, rings out. Normally forages in pairs and occasionally accompanies mixed-species flocks.
