The West Peruvian dove or Pacific dove (Zenaida meloda) was first described in 1843 by the Swiss naturalist Johann Jakob Baron von Tschudi. It is closely related to the North American White-winged dove (Zenaida asiatica), but is now considered a separate species by ornithologists due to genetic and behavioral differences. Specimens are brownish-gray above and gray below, with a bold white wing patch that appears as a brilliant white crescent in flight and is also visible at rest. Adults have a bright blue (almost indigo), featherless patch of skin around each eye. The legs and feet of adults are red, but unlike Z. asiatica, their eyes are brown. Both sexes are similar, but juveniles have a lighter color than adults, they do not have blue eye rings, and their legs and feet are brownish-pink
