The "hooded seedeater" was a proposed bird species described by Austrian ornithologist August von Pelzeln as Spermophila melanops in 1870. The only known individual was heavilymoulted and caught in October 1823 from a flock of other seedeater species at the edge of a lake 15 kilometresnorth of Registro do Araguaia, Brazil. It is now considered to be either an abnormal specimen of the yellow-bellied seedeater or a hybrid. The bird had a black crest and throat, the upperparts were olive, and the underparts showed a dingy buff. In contrast, a typical yellow-bellied seedeater has pale yellow underparts and the black colouring extends to the upper breast.
