Description

The White's Thrush is a largest of Kazakhstan's thrushes, larger than the Mistle Thrush. The upperparts background is golden-buffy; the underparts background is golden-yellowish, lighter on the abdomen. The full body and head have the large black spots of mostly crescent form, these spots form the scaly pattern. Bird in flight shows the pale corners of the of tail. The underwings coverts are white with the broad black longitudinal band. From above the yellow longitudinal bands are appreciable on the wings. Males and females are similar. The seasonal differences of plumage are insignificant. But there are the individual variations of the background's color from more golden to more dark-olive. Tail is quite short. Juveniles are similar on adults but the dark scaling on upperparts is alike to the cross-cut strips; the underparts' spots are rarer and rounder in form. The White's Thrush moves on ground not by jumps as other thrushes but at a foot-pace. Weight 100-200 grams, length 27-30, wing 15,8-17,6, wingspan 44-48 cm.
