Zanzibar Boubou Laniarius sublacteus

A heavily built black-and-white bushshrike. The upperparts are cleanly black and the underparts are white with a pinkish tinge. Uses habitats with a dense understory, including riparian thickets, coastal scrub, forest, and gardens. Found in pairs, which usually skulk but sometimes hop about in the open. Similar to Tropical Boubou, but barely overlaps in range and lacks a white shoulder patch. Also similar to the smaller Black-backed Puffback, but separated by the lack of white on the upperparts. Has a diverse range of vocalizations, including a hollow rising whistle, up-and-down “laser gun” notes, rasps, and croaks, often delivered in a duet by a pair.
