Description

The guira cuckoo has a total length of approximately and weighs . The sexes are very similar in appearance, except that the female is slightly larger than the male. Juveniles appear quite similar to adults. The species has dark brown upperparts streaked with white, and whitish-buff throat, breast, underparts and rump. The tail is relatively long and broad, dark brown in color with a white-tip, and the legs are dark gray. The eyes and beak are yellow to orange, with a thin ring of featherless yellow skin around the eye (this commonly fades in

Food and feeding

The guira cuckoo is an opportunistic predator, gathering small prey items on the ground or searching for them among branches. It feeds on worms, insects and other arthropods, tadpoles and frogs, eggs, small birds (especially nestlings) and small mammals such as mice. It also has been observed feeding on lizards.Bernarde, Paulo Sérgio; Mota da Silva, Ageane; Recoder, Renato (2016). "Predation on the lizard ''Pantodactylus parkeri'' Ruibal, 1952 (Squamata: Gymnophthalmodae) by ''Guira guira'' (Aves, Cuculidae) in the Pantanal at Pocone, Western Brazil". ''Herpetology Notes'' 9: 279-281.

Breeding

The nest is built on a tree fork from the ground. The eggs (from 5 to 7) are dark green and covered with a chalky layer. They are incubated either in individual or community nests; in the latter one can find up to 20 eggs. Under community nests there are many broken eggs. The competition between young being great, mortality is significant.
