Sulawesikoekoek Cuculus crassirostris

A large, long-tailed cuckoo with chocolate-brown upperparts and tail, a contrasting pale gray head, and thickly barred underparts. Juvenile has a black head and whitish underside. A seldom-seen bird of forested lowlands and mountains, most abundant in the foothills. Distinguished from most other cuckoos by the heavy barring below and the brown back. Separated from Large Hawk-Cuckuoo by smaller size, absence of throat streaking, and lack of any rufous throat coloration. Distinctive call, often given before dawn, is rapid, three-note “kaka-koo.”
