Chachalacas, Guans and Curassows (Cracidae)

White-winged Guan (Penelope albipennis) - HBW 2, p. 349

French: Pénélope à ailes blanches German: Weischwingenguan Spanish: Pava Aliblanca

Taxonomy: Penelope albipennis Taczanowski, 1877, near Tumbez, Peru; type from Santa Lucia.
Forms superspecies with P. purpurascens, P. perspicax, P. jacquacu and P. obscura. Probably closely related to P. purpurascens or P. jacquacu (see page 314), but specific status now warranted; validity as species questioned in past, with suggestions that it had been described from a partially albinistic specimen of P. ortoni or P. purpurascens, or that it constituted a morph or variant of one of these species. Monotypic.

Distribution: Extreme NW Peru; recent records only from Lambayeque; historically, also occurred in Tumbes and Piura, where some populations may persist. Original range supposed to extend N to near border with Ecuador, and S to R Chicama, La Libertad. Might also be present in large swampy area bordering Gulf of Guayaquil, in SW Ecuador.
