Range Description

Sporophila falcirostris is rare in the Atlantic forest of south-east Brazil, east Paraguay and north-east Argentina. In Brazil, recent records are concentrated in Rio de Janeiro and So Paulo, with others in Bahia (Silveira et al. 2005, A. C. De Luca and P. Develey in litt. 2007]), Esprito Santo (1940, 2003-2004 [Simon 2004] and undated), Minas Gerais (specimen from 1936), and Paran (2001-2004 [Carrano et al. 2004] and a specimen from 1930). In Argentina, recent records come from Misiones: ro Iguaz, ro Paran (Areta et al. 2009, in review, Krauczuk and Casta 2009, Bodrati et al. in press) and the Yaboty Biosphere Reserve (La Grotteria and Alvarado 2012). The Paraguayan records are from Salto do Guara (1977) and Mbaracay (1995) in Canindey, and Caaguaz in Caazap (1995) (Madroo and Esquivel 1995, Lowen et al. 1996). It has been considered locally common, with recent records in Argentina of hundreds of individuals during mast seeding of Guadua chacoensis bamboo (A. Bodrati in litt. 2012; Areta et al. in review). It is much rarer than the sympatric Buffy-fronted Seedeater S. frontalis (L. F. Silveira in litt. 2012).
