Yariguies brush finch

The Yariguies brush finch (Atlapetes latinuchus yariguierum) is a subspecies of the yellow-breasted brush finch, discovered in 2004 in Colombia.

Description
The feathers of the breast, abdomen, and throat are yellow; those of the coverts, primaries, secondaries, scapulars, auriculars, lores, and tail are black; the crown feathers are russet. It is unique among its conspecifics because it has a jet black back, wing and tail.

Distribution and habitat
Its habitat is the remote cloud rainforest in the northern Colombia. The pristine area where the birds live is one of the last remaining such Andean cloud forests in the country. The government has established a 190,000 ha park in the region (Donegan & Huertas 2005; Huertas & Donegan 2006). The discovery was made by Thomas Donegan, of Fundación ProAves and Blanca Huertas, of the Natural History Museum and University College London, together with Elkin Briceno of CDMB. The research team had studied the isolated and densely vegetated region in various expeditions over a period of three years. Some regions had to be reached by all day hikes or helicopter drop.

Species discovery
The bird has been discovered in the remote Yariguies mountains in an expedition co-led by Thomas Donegan of Fundación ProAves and Blanca Huertas, a curator at the Natural History Museum in London. According to the researchers, the region was so little explored that several more hitherto undescribed birds and butterflies are found there (Donegan & Huertas, 2006). Huertas, a lepidopterologist by training, found several taxa of butterflies new to science (Huertas & Arias 2007). Further information about the biological exploration of the region is found in expedition reports (Donegan & Huertas 2005; Huertas & Donegan 2006). The vernacular name "Yariguies brush finch" was selected because the yellow-breasted brush finch, as a subspecies of which it is currently classified, is to be split into several species, and it is not clear at the moment to which of these the newly described bird would belong (Donegan & Huertas, 2006).

Etymology
The bird is named after the Yariguies indigenous tribe who give their name to the mountain range where the bird was found. Serranía de los Yariguíes was declared a national park last year by the Colombian government and a large forest nature reserve was recently established in the region by Fundación ProAves, Colombia's bird conservation NGO.
