Buntings and New World Sparrows (Emberizidae)

Patagonian Yellow-finch (Sicalis lebruni) - HBW 16, p. 633

French: Sicale de Patagonie German: Magellangilbammer Spanish: Chirigüe Austral

Taxonomy: Pseudochloris lebruni Oustalet, 1891, Misioneros, Santa Cruz, Patagonia, Argentina.
Molecular-genetic data suggest that genus is most closely related to the “hooded” group of sierra-finches (Phrygilus atriceps, Phrygilus punensis, Phrygilus gayi and Phrygilus patagonicus); also, that it belongs within the tanager family (Thraupidae). Present species may form a superspecies with S. olivascens; previously considered conspecific, but differs significantly in plumage, shape, structure and vocalizations. What originally appeared to be an isolated population of present species was recently discovered in EC Argentina, in Sierra de la Ventana (S.. View all taxonomy...

Taxonomy: Pseudochloris lebruni Oustalet, 1891, Misioneros, Santa Cruz, Patagonia, Argentina.
Molecular-genetic data suggest that genus is most closely related to the “hooded” group of sierra-finches (Phrygilus atriceps, Phrygilus punensis, Phrygilus gayi and Phrygilus patagonicus); also, that it belongs within the tanager family (Thraupidae). Present species may form a superspecies with S. olivascens; previously considered conspecific, but differs significantly in plumage, shape, structure and vocalizations. What originally appeared to be an isolated population of present species was recently discovered in EC Argentina, in Sierra de la Ventana (S Buenos Aires); later suggested to be some form of Sicalis auriventris; however, nesting habits are quite different from both species (see page 434); further investigation needed. Monotypic.

Distribution: S Argentina (S from S Rio Negro) and extreme S Chile (from NE Magallanes) S to N Tierra del Fuego.
