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 3,900 ft) in Colombia, Panama and Costa Rica.[1][2]

Taxonomy

Until recently, the Black-headed Brush Finch was placed in the genus Buarremon.[3]

The Black-headed Brush Finch is 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] When split, the taxon costaricensis of Costa Rica and western Panama has been treated as a monotypic species (the Grey-striped Brush-finch, A. costaricensis), a subspecies of the Stripe-headed Brush-finch, or a subspecies of the Black-headed Brush Finch, with most authorities preferring the last treatment.[4] 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]
