Buntings and New World Sparrows (Emberizidae)

Chestnut-bellied Seed-finch (Oryzoborus angolensis) - HBW 16, p. 663

French: Sporophile curio German: Braunbauch-Reisknacker Spanish: Semillero Curió
Other common names: Lesser Rice Grosbeak, Lesser Seed-Finch (when treated as conspecific with O. funereus)

Taxonomy: Loxia angolensis Linnaeus, 1766, Angola; error = eastern Brazil.
Genus sometimes subsumed in Sporophila. Molecular evidence suggests that genus as currently constituted may not be monophyletic, and some of its members may have closest relatives in Sporophila; more data necessary in order to resolve a basal polytomy in the phylogeny. Present species commonly treated as conspecific with O. funereus; they hybridize in S Colombia (upper Magdalena Valley), but apparently only to a limited extent. Proposed race theobromae (known from two specimens from upper Magdalena Valley in Tolima and Huila, in Colombia) is synonymized with torr.. View all taxonomy...

  • torridus (Scopoli, 1769) - E & SE Colombia, Venezuela, Trinidad and Tobago, the Guianas, and Amazonian Brazil S to lowlands of E Ecuador and E Peru.
