A typical Old World cuckoo, with gray-and-white plumage and long wings and tail. Powerful, falcon-like flight. A brood parasite that lays its eggs in the nests of many other bird species. Found in all types of savannah and woodland. Extremely vocal when breeding, giving a distinctive “hoo-hao”. Extremely similar to Common Cuckoo, but has more yellow at the base of the bill; nearly half of the bill is normally yellow. Also similar to Lesser and Madagascar cuckoos, but larger, and without a contrastingly black tail and rump.
