tertials, and upper tail-coverts, pale chestnut-brown, streaked 

 irregularly with numerous narrow lines of black ; all the 

 wing-coverts, and the base of the primaries, white, the distal 

 half of the primaries greyish-black ; the secondaries patched 

 with black and white ; the base of the tail-feathers white, 

 the ends mottled with black and buify-white, crossed with 

 two narrow bars of black, the extreme tips white ; the 

 breast, and all the under surface of the body, white ; legs, 

 toes, and claws, clay-brown. The total length is about 

 seventeen inches. From the carpal joint to the end of the 

 wing, nine inches and three-quarters. 



The males that are killed in the winter half-year have the 

 feathers of the neck of sandy-brown streaked with black, 

 like the same part in the female, which does not change with 

 the season. 



The adult female is of the same size as the male, and has 

 the head and neck mottled and streaked with black on a 

 ground of sandy-brown ; the chin white ; the neck below 

 without any appearance of transverse bars at any season ; 

 the wing-coverts have less white than those of the males ; 

 the white feathers on the breast, sides, and flanks are 

 marked with short transverse bars of black. Females in 

 other respects resemble the males. In recently killed 

 examples, the bases of the feathers, excepting those of the 

 head and neck, are frequently suffused with a delicate, and 

 evanescent, rose tint, similar to that which has been men- 

 tioned as occurring in the previous species. 



A bird in down obtained in the department of Seine-et- 

 Marne has the upper parts fawn-coloured with broad patches 

 of blackish-brown ; from the base of the bill to the auricle 

 a reddish-brown streak, and a white streak from the bill to 

 the eye; throat and upper part of neck pure white, with 

 rusty yellow markings so disposed as to indicate faintly the 

 outlines of the collar and gorget afterwards borne by the 

 male only ; breast and abdomen dull white.
