Rufous-rumped Seedeater (Sporophila hypochroma)

Other Names (World)
Rufous-rumped Seedeater, Grey-and-chestnut Seedeater, Gray-and-chestnut Seedeater, Rufous-naped Seedeater

Family
Thraupidae (Tanagers)

Size
10 cm

First Described (Guide)
Todd, 1915

Habitat
Marshes, seasonally flooded grasslands, pastures and savanna-like areas. From sea-level - 1,100 m.

Range (Guide)

Argentina (B), Bolivia (B), Brazil (NB), Paraguay (B).

Locally in northern and eastern Bolivia (Beni, La Paz and western Santa Cruz), south-western Brazil (southern Mato Grosso and southern Goi�s), central Paraguay, north-eastern Argentina (eastern Formosa and eastern Chaco south to Corrientes, Entre R��os and northern Buenos Aires) and western Uruguay.

Rarity Status
Currently this species is not classified as a rarity in this country OR information has not been updated.

Population
Estimated population is unknown (2010) and decreasing.

Status NT
Habitat destruction and degradation through conversion to agriculture, intensive cattle-grazing and afforestation with non-native tree genera, and pressure from trappers, are the main threats.

Subspecies
No subspecies.

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), Dark-throated Seedeater (Sporophila ruficollis), Marsh Seedeater (Sporophila palustris), 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.
