Genus Neomorphus

Rufous-vented Ground Cuckoo - As other species in the genus Neomorphus, the Rufous-vented Ground-cuckoo is generally highly inconspicious and infrequently seen. While overall unlikely to be threatened due ot its large range, one subspecies, maximiliani , may be extinct, and another, dulcis , is very rare and likely to be threatened. The subspecies vary primarily in the details of the chest- and crown-pattern, and the colour of the tail and wings.

Red-billed Ground Cuckoo - The Red-billed Ground-cuckoo is a species of cuckoo in the Cuculidae family. It is found in Brazil, Colombia, Ecuador, and Peru. Its natural habitat is subtropical or tropical moist lowland forests.

Banded Ground Cuckoo - Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montanes. It is threatened by habitat loss.

Rufous-winged Ground Cuckoo - The Rufous-winged Ground-cuckoo is a species of cuckoo in the Cuculidae family. It is found in humid primary forests in northern Brazil, Guyana, Venezuela, and Colombia. At 50 cm , it is the largest South American cuckoo together with the other members of the genus Neomorphus.

Scaled Ground Cuckoo - The Scaled Ground-cuckoo is a species of cuckoo in the Cuculidae family. It is endemic to the Amazon Rainforest near the Tapajos River in Brazil, but much confusion exists over the exact limits of its range and the features useful for separating it from the very similar Rufous-vented Ground-cuckoo . Consequently, it has often been considered a subspecies of the Rufous-vented Ground-cuckoo.
