Pigeons and Doves (Columbidae)

Socorro Dove (Zenaida graysoni) - HBW 4, p. 159

French: Tourterelle de Socorro German: Socorrotaube Spanish: Zenaida de Socorro
Other common names: Grayson's Dove

Taxonomy: Zenaidura graysoni Lawrence, 1871, Socorro Island.
Formerly placed in genus Zenaidura. Has frequently been considered conspecific with Z. macroura, but captive studies revealed distinct differences in visual displays and vocalizations; the two species mate assortatively in captivity; hybrids produced by cross-fostering present species under Z. macroura, with resultant sexual imprinting on the latter. Best considered to form a superspecies with Z. macroura and Z. auriculata. Monotypic.

Distribution: Formerly Socorro I in Revillagigedo Archipelago (off W Mexico); now extinct in wild.
