Hocco de Koepcke Pauxi koepckeae

An impressively large and critically endangered bird found only in the remote Cerros del Sira mountain range in central Peru. Plumage is usually glossy black with a white vent and white tip to the tail, but a small number of females have mostly chestnut plumage. Both sexes have a bulbous blue casque on the forehead and a red bill. Inhabits lush cloud forest, where it usually remains on the ground. Song is an incredibly low-pitched hum; also gives soft grunts and clucks.
