Distribution

Saffron-billed Sparrow breeds in two disjunct geographic regions. The larger region encompasses areas of eastern Bolivia, southeastern Brazil, southern Paraguay, and northeastern Argentina. The second, smaller, region stretches from central Bolivia south to northern Argentina (Hellmayr 1938, Silva 1991, Parker et al. 1996). In Paraguay the species is found a maximum of 110-120 km west of the Paraguay River (Hayes 1995). However, they have been observed west of the Paraguay river in Formosa province, Argentina (Nores 1992). Saffron-billed Sparrow is considered to be sedentary (Jaramillo 2011).

Generally, Saffron-billed Sparrow is found from the lowlands up to a maximum elevation of 1400 m (Parker et al. 1996). In Bolivia, the species has been recorded between 83-2673 m (mean = 1007 m; Soria-Auza 2009).

The center of elevational abundance is in the lower tropical zone (Parker et al. 1996). This species occurs in the following Zoogeographic Regions: central South America, and Atlantic forest (Parker et al. 1996).

Endemic to the Americas.

Saffron-billed Sparrow is primarily found in tropical deciduous woodland. Additional habitats used by this species include edge of tropical lowland evergreen forests and gallery forests (Ridgely and Tudor 1989, Parker et al. 1996, Perry et al. 1997, Jaramillo 2011). Saffron-billed Sparrow occurs in second-growth forests as well as in more mature forest (Rougés and Blake 2001). They also occur in narrow gallery forests along waterways where fire and other environmental conditions prevent the spread of vegetation away from the river (Parker et al. 1996). This is corroborated by observations of Saffron-billed Sparrow populations declining after the reduction of edge habitat by woodlot fires (Hayes 1995, Willis 2003).
