Costa Rican brushfinch

The Costa Rican brushfinch or grey-striped brushfinch (Arremon costaricensis) is a species of bird in the family Passerellidae. It lives in the undergrowth of humid forest, especially near the edges, at altitudes of 300 to 1200 m in Panama and Costa Rica.

Taxonomy
The Costa Rican brushfinch is often treated as a subspecies of the stripe-headed brushfinch (A. torquatus), but was determined a distinct species, together with the black-headed brushfinch, on the basis of differences in vocalization, plumage, and genetics.
