The family Cracidae (chachalacas, guans and curassows), endemic to the Neotropics, comprises a group of large, forest-dwelling, frugivorous (fruit-eating) birds (Brooks 2002a). Cracids are the most endangered avian family in the region, with approximately half of the larger, turkey-sized guans and curassows considered Vulnerable or Endangered.
