El cerquero de Bangs o gorrión montés colombiano (Arremon basilicus)​ es una especie de avepaseriforme de la familia Passerellidae endémica de la Sierra Nevada de Santa Marta, en el norte de Colombia, donde se encuentra en el sotobosque de los bosques húmedos entre los 300 y 1200 msnm, en especial cerca del borde del bosque.

Taxonomía

Anteriormente se consideraba una subespecie del cerquero cabecilistado (A. torquatus), pero desde 2010 se consideran especies separadas, por sus diferencias en la genética, los cantos y el plumaje.

Sierra Nevada brush finch

The Sierra Nevada brush finch (Arremon basilicus) is a species of bird in the Passerellidae family.

It is found in the undergrowth of humid forests, especially near the edges, at altitudes of 300 to 1,200 metres (980 to 3,940 ft) in the Sierra Nevada de Santa Marta in northern Colombia.

Taxonomy

The Sierra Nevada brush finch was often treated as a subspecies of the stripe-headed brush finch (A. torquatus), but was determined a distinct species on the basis of differences in vocalization, plumage, and genetics. The SACC split the group in 2010.

Sierra Nevada Brushfinch formerly was included in a broadly distributed species, Stripe-headed Brushfinch, which extended from Costa Rica south to northern Argentina. “Stripe-headed Brushfinch” now is partitioned into no fewer than eight (!) species, most of which have restricted geographic distributions. Sierra Nevada Brushfinch fits this pattern, as it is entirely restricted to montane regions of the Sierra Nevada de Santa Marta in northern Colombia. The natural history of Sierra Nevada Brushfinch is very poorly known. Generally, however, its behavior is similar to that of related species: Sierra Nevada Brushfinches are solitary or in pairs, and, while generally fairly common, they easily are overlooked as they forage quietly on the ground or in the undergrowth of humid forest and dense second growth.
