Buntings and New World Sparrows (Emberizidae)

Double-collared Seedeater (Sporophila caerulescens) - HBW 16, p. 654

French: Sporophile à col double German: Schmuckpfäffchen Spanish: Semillero Corbatita
Other common names: Screaming Seedeater

Taxonomy: Pyrrhula caerulescens Vieillot, 1823, Brazil.
Molecular evidence suggests that genus is closely related to Oryzoborus, which should perhaps be subsumed within it; further, that both genera should be placed in the tanager family (Thraupidae). Molecular-genetic data indicate that present species belongs in a clade with S. collaris, S. luctuosa and S. nigricollis; visual similarity suggests that it may be closest to S. albogularis, but latter was not included in that study. Race hellmayri formerly known as ornata, but that name invalid, as preoccupied. Three subspecies recognized.
