White-crowned koel
The white-crowned cuckoo or white-crowned koel (Cacomantis leucolophus ) is a species of cuckoo in the family Cuculidae. It was originally described by Salomon Müller as Cuculus leucolophus. It was later placed in the monotypic genus Caliechthrus , but most taxonomists place it the genus Cacomantis because it has a similar song to other cuckoos in this genus and it is genetically similar to the pallid cuckoo (Cacomantis pallidus ). It is found in New Guinea and neighbouring Salawati Island.
