180 GOOSANDER. 



tail grey, on the sides, posterior to the line of the 

 legs, shading into a pale greyish white, freckled with 

 a darker tint juills dull black; the head and upper 

 part of the neck is rich glossy blackish-green, often 

 with purple rejections, having the plumes of the 

 crown and nape long and silky, drooping behind. 

 The female, known under the name of Dun-diver, 

 is very different ; the sides of the breast, flanks, 

 and upper parts, from the insertion of the neck 

 downwards, of the grey colour which marks the 

 lower back of the male ; the quills are greyish black 

 and the tertials are of a deeper shade, and have 

 black shafts. The only relief here is produced from 

 the greater covers being broadly tipped with white 

 and concealing the dark base of the secondaries, the 

 half of which is also white; these united exhibit a 

 triangular patch or speculum of considerable size ; 

 the head and neck are reddish brown, nearly pale 

 chestnut brown, and the feathers on the hind head 

 and neck are much elongated, loose, and rather 

 hackled in structure, showing a curious sexual dif- 

 ference in the development of this ornament, and 

 which was long brought forward as only incidental 

 to the male. The chin and throat are white, and 

 the fore part of the breast, belly, and vent are 

 generally yellowish white, but sometimes present a 

 depth of tint equalling those parts of the male. The 

 bill, legs, and feet are of a duller vermilion and 

 orange.
