White-browed brushfinch
Template:Short description Template:Speciesbox
The white-browed brushfinch (Arremon torquatus) is a species of bird in the family Passerellidae. It lives in northwestern Argentina, Bolivia, and southern Peru. It is generally common in forest and dense second growth, mainly at altitudes of Script error: No such module "convert"., but locally it occurs at far lower altitudes.[1] It previously was considered the nominate subspecies of the stripe-headed brushfinch.
Taxonomy
Until recently, the white-browed brushfinch was placed in the genus Buarremon.[2]
Considerable racial variation existed in the formerly named stripe-headed brushfinch, and based on ecology, morphology, song, and molecular work it was recently suggested that it be split into eight species.[3]
