The female is an almost uniform earth}' brown above and below, 

 the feathers of the rump and upper tail-coverts alone being broadly 

 tipped with dull brownish blue ; the feathers of the head, nape, 

 upper back, cheeks, chin, throat, breast, and flanks have greyish-white 

 shaft-lines and tips, and the axillaries, under wing-coverts, and under 

 tail-coverts have broad transverse greyish-white terminal bands ; the 

 secondaries and the adjoining five primaries have a broad white sub- 

 basal band or bar ; inuer margin of quills greyish white in the 

 centre, shading into greyish brown towards the base and tip. After 

 the autumn moult the blue is slightly obscured by duller margins of 

 the feathers. Birds of the year and young in first plumage appear 

 to be unknown in collections, but are described as somewhat resem- 

 bling the females in their plumage. Some writers consider the so- 

 called females to be young birds, and suppose that the adult female 

 resembles the male. 



The Himalayan Bluebird breeds at high elevations throughout 

 the Himalayas, and eastwards throughout the mountains separating 

 China from Thibet.
