Guira Cuckoo

The Guira Cuckoo inhabits savannas and pastures of southern Brazil, eastern Bolivia and northern Argentina. These cuckoos are found in flocks of up to 20 individuals. The species is generally common and, with deforestation, has been expanding its range. They  eat arthropods, frogs, lizards, and snakes as well as the juvenal birds and bird eggs.

Guria Cuckoos are thought to be closely related to anis. Molecular studies of cuckoo systematics, however, leave ornithologists somewhat at a loss. Cuckoos appear to have no close living relatives among other bird families (Handbook of Birds of the World—Alive).
