Female. Above olive-brown to brown from forehead to tail, the rump and upper tail-coverts more rufous than elsewhere ; the chin and throat are generally much more spotted with dark brown than in the male and the breast less spotted ; the rufous on the wings is much paler and duller.

Colours of soft parts and Measurements practically as in the male.

Distribution. Northern Asia from West to extreme East, in winter wandering South to Northern India, Assam, Burma and China.

Nidification. This Thrush breeds during May and June as far North as the limits of tree-growth, making a rough and untidy nest of grass, twigs, moss, etc., lined with mud and with a further lining of fine grasses. The nest is generally placed on small isolated trees and often within a foot or two of the ground. The eggs number four or five and are of the Blackbird type, though some are rather more definitely blotched and spotted. Forty-eight eggs average 27.8 x 20.6 mm.: maxima 30.6 X 19.5 and 27.0 x 22.2 mm.; minima 24.1 xl9.2 mm. and 24.2 x l9.0 mm.

Habits The Dusky Thrush is an inhabitant of open, semi-wooded country and even when on migration in its winter quarters prefers open fields and grass-lands with thin forest rather than the denser woods. Its flight is swift and powerful and it is said to have a rough harsh note.
