MOTACILLA. 289 



In normal winter plumage the whole back, .scapulars, rump, and 

 shorter tail-coverts become grey; the lesser wing-coverts grey 

 mixed with black ; the black on the lower throat and fore neck 

 gives place to white, and the black on the upper breast is reduced 

 to a crescentic patch. 



The young in first plumage are like the adults in winter, 

 but have the grey of the upper parts much paler and the crown, 

 nape, and hind neck grey like the back ; the head and lower plumage 

 are suffused with yellow and the black patch on the breast is very 

 small and ill-defined. 



The summer plumage of the adult is probably assumed in the 

 first spring, except in the case of the female, which appears to have 

 the black of the crown and nape mixed with grey at first, probably 

 during the whole of the first summer. 



Bill black, bluish below ; iris brown ; legs and claws dark brown 

 or nearly black. 



Length nearly 8 ; tail 3-6 ; wing 3-5 ; tarsus -85 ; bill from 

 gape '75. 



Distribution. A winter visitor to the eastern portion of the 

 Empire from Assam down to Central Tenasserim. The western 

 limit of this species appears to be Nepal on the Himalayas and 

 Mirzapur in the plains. It is also found in the Andamans. This 

 Wagtail is found throughout Eastern Asia, breeding in Eastern 

 Siberia and China.

Coloration. In normal full summer plumage the forehead, 

 anterior part of crown, a broad supercilium, cheeks, ear-coverts, 

 and sides of the neck white ; remainder of crown and nape, a 

 streak from the lores through the eye and over the ear-coverts, 

 chin, throat, and upper breast black ; remainder of lower plumage 

 white shaded with grey on the flanks ; upper plumage grey, turning 

 to black on the upper tail-coverts ; lesser wing-coverts grey ; 

 median coverts dark brown broadly tipped with white; greater 

 coverts with the outer webs and a considerable portion of the inner 

 white ; quills dark brown edged with white, the later secondaries 

 very broadly so ; the two outer pairs of tail-feathers nearly entirely 

 white, the others black. 



In normal winter plumage the chin and throat are white, and 

 the black on the breast is reduced to a narrow crescent extending 

 laterally along the sides of the throat. 



Young birds resemble the adults in winter plumage, but the whole 

 forehead and crown are grey like the back and the white parts, 

 especially of the head, are suffused with yellow. The eye -streak is 

 less distinct and brown.
