The West Peruvian Dove, sometimes known as the “Pacific” Dove is a close relative of the North American White-winged Dove (Zenaida asiatica), in fact the two have been considered conspecific until relatively recently. In terms of plumage the two species are quite similar, although the West Peruvian is more vinaceous on the underparts and has a darker, deeper blue orbital ring. But these two species differ markedly in their territorial song, a vocalization which is not learned in pigeons. The West Peruvian Dove is a species of arid areas, but it adapts well to agricultural sites, urbanization, and its population and range are increasing quite dramatically. In Chile, this dove was restricted to the very far north up until recently. Beginning about a decade ago stray individuals have been found farther and farther south and these have begun to breed. Currently the species is regular south to the Atacama region in Chile, and now pioneering individuals have reached the latitude of Santiago. This is a substantial range increase! The ability to colonize new places is clear, particularly now that a few have even been found in Northwest Argentina, so the species has successfully crossed the Andes. Eventually this dove may spread throughout arid zones in the southern cone of South America.
