| Abstract: | Populations of the Yellow-billed Cuckoo, Coocyzus americanus, west of the Rocky Mountains have average wing lengths slightly greater than those of eastern North America, but the difference is not sufficient for taxonomic recognition. There is no geographically oriented variation in bill size or color, and the species is best considered monotypic. |
