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, though they do have their own reproductive peculiarity: all members of the genus are sex-role reversed, so that the smaller male provides most of the parental care. Male pheasant coucals invest in building the nest, incubate for the most part and take a major role in feeding the young. At least one coucal species, the black coucal, is polyandrous.
