Cacomantis

Cacomantis is a genus of cuckoo in the family Cuculidae. The genus name is derived from the Greek kakos meaning evil or ill-boding and mantis for prophet and is derived from their association with "rains" being supposed to be predicted as also ill fortune and bad weather. Most of them have a round nostril and are mainly in brown and gray colours. The tails are graduated and barred. The bars are transverse in sonneratii and oblique in all others.

The genus Cacomantis was introduced in 1843 by the German naturalist Salomon Müller with the plaintive cuckoo as the type species. The genus name is from the Ancient Greek kakomantis meaning "prophet of doom".
