Rufous-browed Wren

The rufous-browed wren is 10 to 11.5 cm (3.9 to 4.5 in) long and weighs 11 g (0.39 oz). The adults of both sexes of the nominate subspecies have a dark brown crown, back, and rump and a warm brown tail. Their back and tail have dark bars. They have a pale buff supercilium and darker brown cheeks. Their chin is buffy and their throat and chest yellowish buff that is darker on the sides. The lower belly and vent area are barred. Compared to the nominate, T. r. chiapensis is darker above with a rufous cast to the throat and a white belly, T. r. nannoides's back is darker and the barring on the flanks heavier, and T. r. rehni is more reddish brown above and its throat more yellowish.

T. r. chiapensis is the most northerly of the rufous-browed wren subspecies; it is found in the mountains of Chiapas in southern Mexico. The nominate T. r. rufociliatus is found in central and southern Guatemala and northern El Salvador. T. r. nannoides is limited to Santa Ana Volcano in western El Salvador. T. r. rehni is found in Honduras and northwestern Nicaragua. The rufous-browed wren inhabits humid montane forest of several types. In Guatemala it ranges in elevation from 1,700 to 3,500 m (5,600 to 11,500 ft) but has been found as low as 1,250 m (4,100 ft) in Nicaragua.

The rufous-browed wren usually forages in pairs, and usually near the ground in thick foliage but also in aerial epiphytes. It has been recorded taking caterpillars but further details of its diet are lacking.
