The rusty-winged barbtail (Premnornis guttuliger) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Colombia, Ecuador, Peru, and Venezuela. The rusty-winged barbtail is the only member of its genus.
The rusty-winged barbtail is a sister species of the two species in genus Tarphonomus and the two of them are sister to the tuftedcheeks of genus Pseudocolaptes. The rusty-winged barbtail is not closely related to the two barbtails of genus Premnoplex nor to the Roraiman barbtail (Roraimia adjusta).
The rusty-winged barbtail is 13 to 14.5 cm (5.1 to 5.7 in) long and weighs 13 to 17 g (0.46 to 0.60 oz). The sexes' plumages are alike. Adults of the nominate subspecies have a pale buffish or brownish buff supercilium and a dark brown stripe behind the eye; the rest of their face is streaked brown and buff. Their crown is dark olive-brown with a faint scallop pattern. The sides of their neck and upper back are brownish with pale buff spots, their lower back is browner... Wikipedia →
