Chestnut-winged cinclodes Cinclodes albidiventris

This species occurs from western Venezuela to extreme northern Peru. It is fairly common in high elevation grasslands or open shrubby areas with patches of bare ground. Look for a medium-sized, chunky brown bird with a bold whitish eyebrow and throat. In flight, shows an obvious buffy wing stripe. Singles or pairs forage in the open and are often quite approachable. Compare with Stout-billed Cinclodes, which as you may have deduced from the name has a notably stouter (and more curved) bill. Chestnut-winged was formerly a member of the Bar-winged Cinclodes complex, which has since been split into three species.
