Guira Crotophaga The Crotophaginae are a small subfamily, within the cuckoo family Cuculidae, of four gregarious bird species occurring in the Americas.

The subfamily is notable for the development of cooperative breeding where several females lay eggs in a communal nest.

[citation needed] Incubation takes 15 days for this species.

Study of the cranial osteology and mitochondrial DNA yield the same phylogeny, namely that the Smooth-billed and groove-billed ani are each other's closest relatives, with the greater ani related and the guira cuckoo an earlier offshoot of the group.

[3][4] The members of the family range from Florida in the north, through Central America and the West Indies and through South America south to Rio Negro in Argentina, in open habitats.
