The Gray-headed Chachalaca is a resident of Central America from Eastern Honduras south to northwest Colombia. Like most species of chachalaca, the Gray-headed Chachalaca is plain in coloration. Bright chestnut primaries, conspicuous in flight, distinguish the Gray-headed Chachalaca from the similar Plain Chachalaca (Ortalis vetula). Gray-headed Chachalacas are largely arboreal and forage in groups of 6 to 12, only occasionally venturing to the ground. These loud birds have a varied diet consisting of fruits such as the spikes of guarumo trees, guavas and guara fruits as well as leaves and sometimes insects. Inhabitants of tangled thickets and brushy second growth woodland, these birds are common throughout most of their range.
