Subspecies
No subspecies.
Sporophila zelichi (Sibley and Monroe 1990, 1993) is no longer recognised following SACC (2009). It is now treated as a colour morph of Marsh Seedeater (Sporophila palustris). 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). A molecular-genetic study of 17 species in genus, including ten in "capped" group ("capuchinos"), indicated that latter form two clades, a northern clade largely north of R Amazon containing Ruddy-breasted Seedeater (Sporophila minuta) and Chestnut-bellied Seedeater (Sporophila castaneiventris), and a southern clade consisting of present species and Copper Seedeater (Sporophila bouvreuil), Tawny-bellied Seedeater (Sporophila hypoxantha), Rufous-rumped Seedeater (Sporophila hypochroma), Dark-throated Seedeater (Sporophila ruficollis), Chestnut Seedeater (Sporophila cinnamomea) and Black-bellied Seedeater (Sporophila melanogaster). Determination of relationships within the southern clade not possible, as genetic differentiation very low and species are apparently part of a very recent and rapid radiation. Has been suggested that present species is a white-throated morph of Dark-throated Seedeater (Sporophila ruficollis) or a colour morph of Tawny-bellied Seedeater (Sporophila hypoxantha). In addition, form described as Narosky's Seedeater (Sporophila zelichi) (from Entre Ríos, in north-eastern Argentina) considered to be a white-necked morph of present species, to which it is vocally identical, and found in same habitat and at same locations as it; or possibly a hybrid between present species and Chestnut Seedeater (Sporophila cinnamomea).
