Comportamiento

Salvin's curassow is basically sedentary, though pairs may shift their territories seasonally in response to food availability.<p>Salvin's curassow forages singly, in pairs, or in family groups, mostly on the ground. Its diet is about 70% fruits, 10% seeds, and the other 20% flowers, leaves, invertebrates, and other items. It takes in sand and small stones to aid digestion and has been seen scavenging animal remains.<p>Pairs of Salvin's curassow appear to stay together year round and not be strongly territorial. In Colombia the nesting season is January to May or June. Males build several nests from which the female chooses one. The clutch size is two eggs.<p>The Salvin Curassow's "booming" song is rendered "mmm mmmMMMM ... BMM’mmmm-mmmm". The male sings mostly at dawn and at night. The female also sings a huskier version. Other vocalizations include a "pieew, pieew" alarm note, a "goorh, goorh" threat response, and a "coh coh" contact call.
