Upper plumage rufescent-brown, feathers dark shafted; forehead white; a conspicuous white nuchal mark; wing-coverts mottled light brown and whitish, feathers dark shafted; quills pale brown with narrow dark bars, and dark tip; winglet dark brown; tail pale rufous with indistinct bars, plainer towards the tip ; beneath chin and throat fulvescent, with a central dark chin-stripe, and a lateral one on each side, bounding the light chin; the rest of the lower parts hair-brown, banded on the abdomen, less so on the breast, with white bars ; thigh-coverts faintly barred with rufous, and the under tail-coverts unspotted fulvescent-white.

The Teesa is very common, and is a permanent resident, breeding principally in April. The nest is usually placed high up in a fork in an umbrageous tree, often a mango forming one of a small clump, generally an outer one; it is a loose structure of sticks and twigs, unlined ; the eggs, from two to four (but most often three) in number are pale bluish-white, unspotted; they are oval in shape and measure about 1.8 in length by 1.5 in breadth.
