Black-billed cuckoo

The black-billed cuckoo (Coccyzus erythropthalmus) is a New World species in the Cuculidae (cuckoo) family. The scientific name is from Ancient Greek. The genus name, kokkuzo, means to call like a common cuckoo, and erythropthalmus is from eruthros, "red" and ophthalmos, "eye".

It is very similar and overlaps in range with the closely related yellow-billed cuckoo. A distinguishing characteristic of the family Cuculidae is laying eggs in the nests of other birds. Although many cuckoos are obligate brood parasites, C. erythropthalmus often incubate their own chicks.
