The Stripe-capped Sparrow is broadly endemic to the Chaco biome of southern South America. It occurs in semi-open woodland across northern Argentina south to Buenos Aires province, as well as northwards into southwestern Paraguay. The species’ most striking plumage features are arguably the russet and gray-striped crown, and the black malar stripe. Generally considered to be fairly common, the Stripe-capped Sparrow is typically found in pairs, or sometimes in small groups, feeding on the ground but singing from atop low trees and bushes. Although it might be considered to be nothing more than a ‘little brown job’, within its range, this dainty little sparrow cannot really be confused with any other species.
