The white-browed brush finch (Arremon torquatus) is a species of bird in the Emberizidae family. It is found in north-western Argentina, Bolivia, and southern Peru. It is generally common in forest and dense second growth, mainly at altitudes of 2,000 to 3,000 metres (6,600 to 9,800 ft), but locally it occurs at far lower altitudes.[2]
Taxonomy
Until recently, the white-browed brush finch was placed in the genus Buarremon.[3]
Considerable racial variation existed in the formerly named stripe-headed brush finch, and based on ecology, morphology, song, and molecular work it was recently suggested that it be split into eight species.[4] These are:[4]
- White-browed brush finch, Arremon torquatus (with subspecies fimbriatus and borelli) in the Andes from north-western Argentina to far southern Peru.
- Costa Rican brush finch, Arremon costaricensis (monotypic) in Costa Rica and western Panama.
- Black-headed brush finch, Arremon atricapillus (with subspecies tacarcunae) in eastern Panama and northern Colombia.
- Grey-browed brush finch, Arremon assimilis (with subspecies larensis, nigrifrons and poliophrys) in the Andes from Peru to Venezuela.
- Perijá brush finch, Arremon perijanus (monotypic) in the Perijá Mountains on the border of Colombia and Venezuela.
- Sierra Nevada brush finch, Arremon basilicus (monotypic) in the Santa Marta Mountains in Colombia.
- Caracas brush finch, Arremon phaeopleurus (monotypic) in the western Venezuelan Coastal Range.
- Perija brush finch, Arremon phygas (monotypic) in the eastern Venezuelan Coastal Range.
