The giant cuckoo is the largest cuckoo in the world. It lives in Australia, New Guinea, and Indonesia and lays eggs in the nests of other birds.
The giant cuckoo stands out with its large size, powerful beak, and gray plumage. It regulates insect populations but reduces breeding success in host parents.
