GOOSANDER. 
tail grey, on the sides, posterior to the line of the 
legs, shading into a pale greyish white, freckled with 
a darker tint prills dull black; the head and upper 
part of the neck is rich glossy blackish-green, often 
with purple reilections, 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.
