Buntings and New World Sparrows (Emberizidae)

Patagonian Sierra-finch (Phrygilus patagonicus) - HBW 16, p. 606

French: Phrygile de Patagonie German: Magellanämmerling Spanish: Yal Patagón
Other common names: Patagonian Hooded Sierra-finch

Taxonomy: Phrygilus gayi patagonicus P. R. Lowe, 1923, Good Success Bay, Tierra del Fuego, Argentina.
Originally described as Fringilla formosa, but that name invalid, as preoccupied. Molecular-genetic studies indicate that genus belongs in tanager family (Thraupidae). Present species may form a superspecies with P. atriceps, P. punensis and P. gayi (the “hooded” group), and molecular data suggest that this group may be closely related to Sicalis. Range overlaps with that of P. gayi in various sites in Andes and NW Tierra del Fuego; some evidence of hybridization in latter, but the two species generally remain separate, and occupy different habitat..

Range overlaps with that of P. gayi in various sites in Andes and NW Tierra del Fuego; some evidence of hybridization in latter, but the two species generally remain separate, and occupy different habitats. Small coastal race minor of P. gayi exhibits some plumage features intermediate between the two species, and may be better included in present species on basis of its preference for forest or forest-edge habitat. Monotypic.

Distribution: Breeds from Maule region of Chile S and from forested areas of adjacent Argentina (S from Neuquén) S to Tierra del Fuego. In winter also N to Valparaíso and Metropolitan Santiago regions.
