pursuit of its quarry. An old Black-Cock {Tetrao tetriai) was 
sprung-, and was instantly pursued by the Eagle, (who must have 
been on a neighbouring- rock unperceived) across the glen, the 
breadth of which was at least two miles. The Eagle made several 
unsuccessful pounces, but as there was no cover and the bird large, it 
probably fell a victim in the end.*

Willughby and Ray seem to have given the young, or female, of this 
species under the title of smaller red-headed duck. Lewin considers 
his brown-headed duck as a distinct species, and states the bill to be 
essentially different. 
Nothing has tended so much to the discovery and ascertaining the 
species of ducks as the singular conformation in the trachea, or wind- 
pipe, of the males of some of this tribe of birds. That of the Golden- 
Eye is so very different from most others, than it is an unerring mark 
of distinction. We have examined many with the rusty-brown head, as 
described by authors for a different species, some of which were males, 
and had the enlargement of the trachea. 
A matured male Golden-Eye weighs near two pounds ; length 
between eighteen and nineteen inches ; bill black ; irides fine bright 
yellow ; head and upper half of the neck black, glossed with green and 
violet, changeable as viewed in different lights ; at the corner of the 
mouth is a large white spot ; the lower part of the neck, the breast, 
and all beneath, are white ; the back, rump, and upper tail coverts, 
black ; scapulars black and white ; the coverts of the wings are black, 
with a white patch on the lesser, and another on the larger coverts ; 
quill-feathers black, except seven of the secondaries, which are mostly 
white ; tail black ; legs orange. 
The female is considerably less. The bill is yellowish towards the 
point ; the head in this, as well as in the male, is full of feathers, which 
makes it appear large ; but instead of being black, it is, as well as the 
upper part of the neck, of a rusty-brown ; round the middle of the neck
