Unadorned Flycatcher | Myiophobus inornatus

Carrikers tiran | Mosquero sencillo | Filipe-simples

The Unadorned Flycatcher is a small, plainly marked tyrant of lower montane forest on the eastern slope of the Andes in south-eastern Peru and Bolivia. Its entire range lies within the guide area. Less is known about its habits than about most of its relatives.

Identification

12 cm, with a short, flat bill with a pale lower mandible. The upperparts are olive-brown, with a narrow, pale eye-ring. The underparts are yellow, with an olive wash on the breast. The wings have two ochre wing bars. A crown patch is absent or small and concealed. The sexes are nearly alike.

Confusion species

Flavescent Flycatcher Myiophobus flavicans is slightly larger and greener, with more distinct yellow spectacles, and usually lives higher. Roraiman Flycatcher Myiophobus roraimae has rufous wing bars. Bran-colored Flycatcher Myiophobus fasciatus is brown with a streaked breast and lives in open scrub.

Habitat

Humid lower montane forest and forest edges of the Yungas, mainly in the understorey and middle levels, roughly between 1000 and 2200 m. It catches insects with short sallies from a branch, often in mixed flocks. Little is known about the nest.

Where the bird is most at home, classified by the vegetation units of the Andes and the west coast.

Range and movements

Peru: on the eastern slope of the Andes in the south-east (Cusco, Puno). Bolivia: on the eastern slope of the Andes in La Paz and Cochabamba. Absent from Colombia, Ecuador and the Galápagos. The species does not occur outside the guide area.

Density map from the occurrence records of GBIF (2006-10-01 – 2026-09-30), counted per 1.41° grid cell and per month and divided by all bird records in that same cell — so the number of birdwatchers does not shape the picture. Colour depth follows that share and fades out gradually, so the map does not follow national borders. Country outlines: Natural Earth (public domain).

How and when to look

Search along roads through Yungas forest at middle elevations, such as in the Kosñipata valley in Peru or around Coroico in Bolivia, and follow mixed flocks in the lower levels.

Conservation status

Least Concern. The range is small, but much of the montane forest on the eastern slope is still intact.

Scientific name

Myiophobus inornatus | Carriker, 1932

Carriker described the species in 1932 and placed it straight away in the genus where it still stands. The genus Myiophobus was introduced in 1850 by Reichenbach. The genus name comes from Greek muia, 'fly', and phobos, 'terror, fear'. The species name comes from Latin inornatus, 'unadorned'. The specimen the first description was based on came from Santo Domingo (Inca Mine), Puno, Peru.
