Asthenes perijana
Perijá Thistletail is endemic to the Perijá Mountains in Colombia and Venezuela.
Appearance
The sexes have the same plumage. Their crown, back, rump, and tail are grayish olive-brown. Their wings are grayish olive-brown with chestnut on the coverts and the base of the flight feathers.
The Perija thistletail is 19 to 22 cm (7.5 to 8.7 in) long and weighs 16 to 21 g (0.56 to 0.74 oz).
Range and habitat
The Perija thistletail is found only in the Serranía del Perijá, a mountain range that straddles the border between northeastern Colombia and northwestern Venezuela. It primarily inhabits páramo grasslands, the upper edge of cloudforest, and dense undergrowth at tree line. In elevation it ranges between 2,950 and 3,400 m (9,700 and 11,200 ft).

Diet and breeding

It is believed to forage by gleaning prey from foliage and branches. The Perija thistletail's breeding season has not been defined but includes July. Nothing else is known about the species' breeding biology.
