This strange bird, with its bald head and huge dark eyes, is also known as the Calf bird, because of its remarkably loud deep call. Like the Cock-of-the-rock, it is a member of the Cotinga family, found only in Tropical America. Its range is defined by the intersection of three rivers: Amazon, Orinoco, and Rio Negro. Though first taken into captivity nearly 60 years ago, it has always been a treasured rarity in zoos. Until the DWA achieved multiple successes in 2011, the only full captive breedings had been at San Diego Zoo, in the 1990s.
Every year since 2007, this remarkable bird has reproduced at the DWA. Through May 2011, 40 had hatched here, with 26 surviving to independence. Prior to this time, the total number successfully reared in US zoos were four at Houston and one at San Diego, with the last hatching occurring in 1989. Offspring from the DWA have been sent around the world, and the first second generation breedings took place at the San Diego Zoo in 2011, with males from Dallas. While performing their courtship display, males make buzzing shrieks that can be heard throughout the Orinoco. Nesting takes place in specially built artificial caves.
