Adult male. General colour above light brown, streaked with 

 blackish brown down the centre of the feathers, the hind neck and 

 sides of neck paler ; the rump ashy white, streaked with blackish 

 brown and slightly tinged with rosy ; lesser wing-coverts light 

 brown ; median and greater coverts dusky blackish, edged with light 

 brown and tipped with sandy buff or creamy white, forming a double 

 wing-bar ; bastard-wing and primary-coverts dusky blackish, edged 

 with ashy brown ; quills dusky blackish, edged with ashy brown, 

 the secondaries with light brown, all fringed with whitish at tho 

 tips, the innermost secondaries more broadly tipped on the outer 

 web ; upper tail-coverts and centre tail-feathers dusky brown edged 

 with pale brown, the latter also white along the inner web, increas- 

 ing towards the outer feathers ; hinder crown like the back ; the 

 entire forehead and vertex dark crimson ; base of forehead and 

 nasal plumes dusky blackish ; lores dusky, surmounted by a broad 

 eyebrow of creamy white tinged with brown ; eyelid and a small 

 streak below the eye creamy white ; ear-coverts light brown like 

 the sides of the face and cheeks, the latter suffused with rosy ; 

 chin-spot black ; rest of throat, fore neck, and breast rosy pink, 

 the feathers edged with hoary white ; abdomen white, with a slight 

 suffusion of pink; sides of body and flanks creamy buff, slightly 

 washed with light brown and streaked with blackish brown, more 

 broadly on the latter ; thighs light brown ; under tail-coverts white, 

 the longer ones with blackish centres ; under wing-coverts and 

 asillaries white, with ashy-brown bases ; quills below dusky, ashy 

 whitish along the inner edge. Total length 5'2 inches, culmen 0*4, 

 wing 2-85, tail 2-05, tarsus 0-6. 



In full summer plumage the adult male loses the ashy-whitish tips 

 to the feathers of the throat and breast, so that these parts become 

 very fine and uniform rosy ; the streaks on the sides of the body 

 are also somewhat intensified. The plumage becomes much worn 

 and abraded during the breeding-season, when the light edges to 

 the feathers get worn off, and a more uniform appearance is put on. 



Adult female. Similar to the male, but wanting the rosy colour 

 on the throat, breast, and rump ; the chin and upper throat black ; 

 the remainder of the under surface white, with blackish streaks on 

 the sides of the body. Total length 5 inches, culmen - 35, wing 

 2*75, tail 2 - 05, tarsus - 55. 



Young. Resembles the old female, but has no red on the crown, 

 the head being like the back and streaked with whitish in the same 

 manner ; rump much paler than the back and mixed with white ; 

 wing-coverts broadly tipped with sandy buff, forming two distinct 

 wing-bars ; no black on the throat ; remainder of under surface 

 white, tinged with yellow on the abdomen ; the breast and flanks 

 spotted with broad marks of black. 



The young bird, after tho first autumn moult, is much yellower
