[QUOTE="Melanie, post: 3474927, member: 3356"] Zootaxa Vol 4148, No. 4, 27 October 2016 Taxonomic revision of Saffron-billed Sparrow Arremon flavirostris Swainson, 1838 (Aves: Passerellidae) with comments on its holotype and type locality NELSON BUAINAIN, GUILHERME RENZO ROCHA BRITO, DANIEL HONORATO FIRME, DANIEL MONTEIRO FIGUEIRA, MARCOS A.
