East Brazilian Chachalaca Ortalis araucuan

Medium-sized chachalaca. Has a rufous crown and speckled throat and breast, contrasting with white underparts. Occurs in wooded areas including second growth, caatinga, and coastal forest, where it forages mostly in trees and occasionally descends to the ground. Usually found in small groups of less than eight individuals. Like other chachalacas, very noisy, emitting a loud rollicking duet “ha-ga-GAA-gogok” repeated continually.
