Cracidae

The cracids (Cracidae) are a family of neognathous birds of the order Galliformes that includes the cursaws, the peahens b> and the chachalacas. They are tropical and subtropical species from South America, Central America and Mexico. A species of chachalaca lives in the southern state of Texas in the United States. The Trinidadian guan (Pipile pipile) and the chestnut-bellied chachalaca (Ortalis wagleri) live on the Caribbean islands of Trinidad and Tobago. Many of the species in this group are found in danger of extinction.

Description

Its appearance is similar to that of the turkey. Curassows and guans live among the trees, but the smaller chachalacas are found in more open environments, among the bushes. Their plumage is generally dark, but curassows and peahens are adorned with colorful figures on their neck, head or beak.

Behavior

They feed on seeds, fruits, insects and worms. They build nests in trees and the female incubates two or more eggs.

Evolution

Studies of Cracidae mitochondrial DNA indicate that the group may have originated in the late Cretaceous. The most modern lineages, however, did not undergo a speciation process until the Eocene. The differentiation between curassows (Crax, Nothocrax, Pauxi and Mitu), and between the species of Aburria and Pipile, was caused by changes in the landscape of South America, mainly due to the elevation of the Andes Mountains, which determined the current courses of the rivers. The distribution of curassows and guans occurred through river systems.
