Introduction

Tawny-breasted Flycatcher inhabits foothills and subtropical forest on the eastern slope of the Andes from Colombia south to Bolivia, and in the Chocó region of the northwestern Andes in Colombia and Ecuador (as well as easternmost Panama). They stay in the undergrowth and at lower levels, especially near water, where they frequently join mixed-species foraging flocks. This flycatcher is a fairly active feeder, flashing its tail and turning abruptly in an almost redstart-like manner. Although similar in appearance to the other Myiobius flycatchers, sharing the yellow rump and rounded, black tail, they are the largest and darkest species of the genus. Furthermore, the Tawny-breasted Flycatcher also occurs at higher elevations than its close relatives. Additionally, the brown coloration on their breast and flanks is distinctive. The call of the Tawny-breasted Flycatcher is an emphatic spikt!

Field Identification

14 cm; 13 g. Large eyes, prominent long rictal bristles. Male nominate race has crown, nape, and upperparts dark brownish-olive, semi-concealed yellow coronal patch, paler supraloral area, pale eyering broader to rear, greyer on face; rump sulphur-yellow, uppertail-coverts black; wings dark with olive-brown feather edges; tail long, rounded, black; throat dirty white, underparts mostly ochre to tawny-brown, central belly dull yellow; iris dark; bill broad, upper mandible grey to black, lower mandible dull pinkish with dusky tip; legs grey. Distinguished from M. sulphureipygius by larger size, darker coloration, especially on underparts. Female is similar to male, but coronal patch cinnamon-rufous or absent. Races differ subtly in plumage, mainly in coloration of upperparts and underparts: schaeferi resembles nominate but has stronger indication of breastband; peruvianus has more distinct band on breast, more extensive yellow below; clarus differs from previous in generally greener upperparts.

SUBSPECIES

Myiobius villosus peruvianus Scientific name definitions

Distribution

E slope of E Andes of SE Peru and NW Bolivia (La Paz).

Distribution

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.

Habitat

Lower and middle levels of montane forest, near streams. Occurs at 900–2100 m, locally down to 600 m; mainly at higher elevations than its congeners in Andes.

Movement

Probably resident.

Diet and Foraging

Arthropods, notably hymenopterans, coleopterans, homopteran bugs, and arachnids. Analysis of 77 prey items taken from stomachs in SE Peru gave: Coleoptera (44%); Hymenoptera (bees and wasps 25%, ants 21%); and Homoptera (planthoppers 5%, cicadas 5%). Singly or in pairs; regularly accompanies mixed-species flocks. Actively forages at low to middle levels, perhaps higher than M. barbatus; often fans tail, reminiscent of Old World fantails (Rhipidura), and droops wings to expose yellow rump; often pivots on perch, and frequently changes perches. Uses flush-and-chase strategy similar to that of Myioborus, pursuing flushed prey in short, acrobatic, aerial sallies.

Sounds and Vocal Behavior

Generally quiet; sometimes a sharp “espít” call note, similar to that of M. sulphureipygius.

Breeding

Not well known; probably similar to that of congeners.
Not globally threatened. Rare to locally common; particularly numerous at El Placer (Esmeraldas), in NW Ecuador. Occurs in Tambito Nature Reserve, in Colombia, Machalilla National Park, in Ecuador, and Madidi National Park and Pilón Lajas Biosphere Reserve, both in Bolivia.
