Blue-billed curassow
The blue-billed curassow or blue-knobbed curassow is a species of bird in the family Cracidae, which includes the chachalacas, guans, and curassows. They weigh between 7-8 pounds and have a herbivorous diet of fruit and greens.
Like other birds, the blue-billed curassow also likes to "sing," or in this case "boom." The males have been observed puffing out their plumage, hunching over, and producing low frequency booms or growls. They sing like this in the mornings and nights. Their songs may serve to ward off rival males, attract a potential mate, or to help maintain their current pair bond with a female.
It is found only in Colombia; areas of its range in the south and east are bordered by the Magdalena River. Its natural habitat is subtropical or tropical moist lowland forest. It is threatened by habitat loss.The number of blue-billed curassow which remain in the wild is only 250–1,000; as a result of the mass destruction and degradation of their habitat.
