Gabela Bushshrike Laniarius amboimensis

A striking bushshrike with a chestnut crown and nape, blackish upperparts with a white wing-stripe, and entirely white underparts. A scarce species that skulks in pairs in the understory of secondary forest and farmbush, including coffee plantations, near Gabela along the Angolan escarpment. Vocalizations are variable, but quality is consistent: a haunting reverberating “whorrrrr,” a sweet musical “til-out, til-out,” and nasal twanging or grating rattles. Tropical Boubou is similar to Gabela Bushshrike but differs by having buffy underparts and a blackish, not chestnut, crown.
