Black-and-white-casqued Hornbill

Also known as Grey-cheeked Hornbill, Grey-cheeked Casqued Hornbill

Black-and-white-casqued hornbills fill central and western African rainforests with heavy, swooping flight that produces a distinctive roaring whoosh from unfeathered feather bases. Breeding pairs seal the female inside a tree cavity using mud and feces, leaving only a tiny slit where the male feeds her and their chicks for months. These noisy, social birds play a crucial role in forest regeneration by dispersing large fruit seeds across the canopy.
