The black-headed brush finch (Arremon atricapillus) is a species of bird in the Emberizidae family. It is found in the undergrowth of humid forest, especially near edges, at altitudes of 300 to 1,200 metres (980 to 3,940 ft) in Colombia and Panama.[1][2]

Taxonomy[edit]

Until recently, the black-headed brush finch was placed in the genus Buarremon.[3]

The black-headed brush finch was often treated as a subspecies of the stripe-headed brush finch (A. torquatus), but the distributions of the two approach each other closely in Colombia with no evidence of intergradation.[4] In addition, the grey-striped brush finch, A. costaricensis has often been treated as a subspecies of the stripe-headed brush finch, or a subspecies of the black-headed brush finch,[4] but based on ecology, morphology, song, and molecular work, it has recently been suggested that A. costaricensis is worthy of treatment as a species.[5] In that case, the black-headed brush finch would only include the subspecies tacarcunae, and be restricted to Colombia and eastern Panama.[5]
