Guans Curassows and Chachalacas: Cracidae
Behavior And Reproduction
We don't know much about cracid life because they are such shy birds. They seem to live socially in small groups or flocks, and their nests are found in groups. They are vocal birds whose calls are loud and cacophonous (having an unpleasant sound). Some of the mountain forest-dwelling species migrate to lower altitudes during the colder months.
Cracids build their nests in trees or bushes. The nest is a flat platform, usually longer than it is wide and built from twigs, plant stems, leaves, grass, and other similar items. Some of the species are polygamous (puh-LIH-guh-mus; having several mates in one season), but no one is certain about the others. Curassow hens lay two eggs; chachalacas, three; and guans, three to four. Experts believe that only the female incubates (keeps warm before hatching) the eggs. Incubation periods vary from twenty-one to thirty-six days, depending on species.
Newborns are able to leave the nest very soon after birth. They are able to fly, hop, and walk along twigs when just a few days old. Cracids spend a great deal of time in the trees, hopping from branch to branch and walking on twigs. Cracids fall prey to jaguars and other big cats.
