Comportamiento

The white-bellied chachalaca forages in groups of six and sometimes more birds, and almost always stays 6 to 10 m (20 to 33 ft) up in vegetation. Its diet is primarily berries and fruits, and it also feeds on leaves, buds, flowers, and invertebrates.<p>Egg laying by the white-bellied chachalaca has been recorded in every month from March to July. Its nest is a small loose platform of sticks lined with leaves. It is placed in a tree, usually between 5 and 20 m (16 and 66 ft) high. The clutch size is two or three eggs that only the female incubates.<p>The white-bellied chachalaca's principal vocalization is "a gruff, burry chattering of four syllables 'k-ku’uh-uh' or 'ch-k-uh-urr'."
