The young bird is brown above, with pale edgings to the feathers; eyebrows white, and some white or rufous about the nape; below white, more or less spotted on the breast, abdomen and flanks with dark brown spots, least numerous in the male; tail pale ashy-brown, with four or five dark broad bands; thigh-coverts with transverse brown bands a narrow dark line down the centre of the chin and throat; and two more, one on each side of the neck, not very distinct in the male, but becoming more so with age ; an occipital crest of several elongated feathers ; under wing-coverts white, with brown spots ; quills and tail beneath light cinereous, with dark bands.
The adult bird has the upper plumage glossy dark brown, in some with an olivaceous tinge, in older birds with a dark slaty hue, especially when freshly moulted; wings and tail banded, the latter with four distinct dark bands; beneath white, the throat and upper part of the breast, with pale yellow-brown, oval spots; the rest of the plumage beneath barred with rich yellow-brown, the bars broad on the breast, belly and flanks ; narrow on the thigh-coverts, but all becoming more narrow by age.
The Gor-besra is one of the rarest winter visitants we have. As yet it has only been doubtfully recorded from the hilly wooded regions near Mhow; outside our limits, on the Neilgherries, it is not uncommon.
With regard to its nidification nothing definite seems to be known, but it is strongly suspected to breed in the more-southern parts of India.
