Summary

The variegated bristle tyrant (Pogonotriccus poecilotis) is a species of passerine bird in the family Tyrannidae, the tyrant flycatchers. It is found in Colombia, Ecuador, Peru, and Venezuela.

Taxonomy and systematics

The variegated bristle tyrant was originally described as Leptopogon poecilotis. It was later moved into genus Pogonotriccus, which was still later merged into genus Phylloscartes. Beginning in 2016 taxonomic systems resurrected Pogonotriccus for this species and a few others.

The variegated bristle tyrant is monotypic. A proposed subspecies, P. p. pifanoi, has not been accepted by most taxonomists.

Description

The variegated bristle tyrant is about 11.5 cm (4.5 in) long; three individuals weighed between 7 and 9.5 g (0.25 and 0.34 oz). The sexes have the same plumage. Adults have a slate gray crown. Their lores and narrow supercilium are grizzled white. Their ear coverts are grizzled white bisected by a vertical black crescent. Their back and rump are olive green. Their wings are dusky with yellowish edges on the flight feathers. Their wing coverts are dusky with wide tawny buff tips that show as two wing bars. Their tail is dusky olive. Their throat is whitish and their breast, flanks, and belly bright yellow with an olive wash on the breast. They have a brown iris, a black maxilla, an orange, yellow-orange, or yellow-brown mandible, and gray or light brown legs and feet.

Distribution and habitat

The variegated bristle tyrant has a disjunct distribution. It is found in the Serranía del Perijá that staddles the Colombia-Venezuela border, locally in the Venezuelan states of Mérida, Táchira, Lara, and Barinas, in all three ranges of the Colombian Andes, and along the lengths of Ecuador and Peru on the eastern slope of the Andes. It inhabits humid subtropical montane forest, extending to wet cloudforest in Venezuela. In elevation it ranges between 1,500 and 2,300 m (4,900 and 7,500 ft) in Venezuela and Colombia, between 1,500 and 2,000 m (4,900 and...
