The rufescent flycatcher (Myiophobus rufescens) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Chile and Peru.[2]

Taxonomy and systematics

[edit]

The rufescent flycatcher was originally described as Myiobius rufescens.[3] In the mid-twentieth century it was reclassified as a subspecies of the bran-colored flycatcher (Myiophobus fasciatus). Following studies that identified plumage and vocal differences among the subspecies, beginning in 2016 taxonomic systems began splitting them.[4][5][6][7][8]

The rufescent flycatcher is monotypic.[2]

Description

[edit]

The rufescent flycatcher is 11.5 to 12.5 cm (4.5 to 4.9 in) long. The sexes very similar. Adult males have a brown crown with a partly hidden orange-buff patch in the middle. Both sexes have brown lores and a short warm buff supercilium on an otherwise warm brown face. Their back and rump are warm brown. Their wings are dark brown with rufous-buff edges on the flight feathers and wide rufous-buff tips on the wing coverts; the latter show as two wing bars. Their tail is dark brown. Their throat and underparts are peachy-buff cinnamon that is lightest on the throat and upper breast. Adult females have a much smaller crown patch or none at all. Both sexes have a brown iris, a black bill with an orange-yellow base to the mandible, and black legs and feet.[9][10]

Distribution and habitat

[edit]

The rufescent flycatcher is found from southern Lambayeque Department in northwestern Peru south along the coast through the rest of the country and slightly into extreme northern Chile's Arica y Parinacota Region. It inhabits rather open landscapes including the edges of forest, secondary woodlands, pastures, and desert scrublands. In elevation it ranges from sea level to 2,700 m (8,900 ft) in Peru but only to about 500 m (1,600 ft) in Chile.[9][10][11]

Behavior

[edit]

Movement

[edit]

The rufescent flycatcher is a year-round resident.[9]

Feeding

[edit]

The rufescent flycatcher's diet and feeding behavior have not been studied. The are assumed to be similar to those of the bran-colored flycatcher, which see here.[9]

Breeding

[edit]

Nothing is known about the rufescent flycatcher's breeding biology.[9]

Vocalization

[edit]

The rufescent flycatcher's dawn song has not been described. Its calls include a "slightly metallic, nasal chieh or tseek, uttered either singly or in series" and a "rattled series of identical notes with a total duration of ⁓0.7‒2.0 [seconds]". Often a pair vocalizes in duet with each making one of the calls.[9]

Status

[edit]

The IUCN has assessed the rufescent flycatcher as being of Least Concern. Its population size is not known and is believed to be stable. No immediate threats have been identified.[1] It is considered fairly common in Peru and rare in Chile.[10][9]
