A coucal is one of about 30 species of birds in the cuckoo family. All of them belong in the subfamily Centropodinae and the genus Centropus. Unlike many Old World cuckoos, coucals are not brood parasites. On the other hand they do have their own reproductive peculiarity: all members of the genus are to varying degrees sex-role reversed so that the smaller male provides most of the parental care. At least one coucal species, the Black Coucal, is polyandrous.(Andersson 1995) Recent DNA evidence^{[citation needed]} suggests that they should be raised to family status, as Centropodidae. In biology, a species is one of the basic units of biodiversity. ... “Aves” redirects here. ... Genera See text. ...
