Cuckoos (Cuculidae)

Yellow-billed Cuckoo (Coccyzus americanus) - HBW 4, p. 595

French: Coulicou à bec jaune German: Gelbschnabelkuckuck Spanish: Cuclillo Piquigualdo

Taxonomy: Cuculus americanus Linnaeus, 1758, South Carolina.
Forms a superspecies with C. euleri. Birds in W North America average longer-winged and have been described as race occidentalis, but much overlap in size exists and most birds cannot be distinguished; “subspecies” records in non-breeding range are questionable. A claimed record of hybridization with C. erythropthalmus refers to a juvenile C. americanus. Monotypic.

Distribution: SE Canada and USA to Mexico (inland N Pacific slope, Baja California and Caribbean lowlands in Tamaulipas and Yucatán Peninsula) and N West Indies. Winters in South America.
