The adult barred becard is 12 cm long and weighs 14 g; it has a conspicuous eye-ring. The adult male has black upperparts with much white in the wings. The sides of the head and throat have yellowish-green shading to white on the rest of the underparts. The underparts are finely barred with black. The adult female has a grey crown and nape, olive-green upperparts and largely rufous wings. The greenish-yellow underparts are finely barred and dusky. Young males are much duller and greener than the adults, with weaker barring. The calls include a soft but persistent ''weet weet weet weet'' or a ''teseep tesep tseep tseep''.
The barred becard is found in the canopy and middle levels of mountain forests, coming lower at edges and in adjacent more open woodland. It is mainly found at altitudes between 1500–2500 m, sometimes higher early in the year. Barred becards actively pick large
