I Will.^ 28 ; Falco fulvus of Lin. Syst. Nat. i. 125 ; or the Ringtail Eagle, or Black 
Eagle of Pen. Brit. Zool. i. 165. In the opinion of some, the ringtail is consi- 
dered as a distinct species ; but the facts stated by Temminck and Selby de- 
1 monstrate its connection with the Golden Eagle See Wern. Mem. vol. iv.

Inferior in size to the preceding. Bid v/hitish ; irides light-brown ; cere 
and feet yellowish-w^hite. Plumage dusky-brown, tinged with cinereous. 
Tail wholly white. Breeds in rocks. Eggs two ; of a white colour, with a 
few reddish spots. In the young^ the plumage is deep-brown, with the mar- 
gins of the feathers lighter coloured. Bill and iris black. Tail with the ba- 
sal half whitish-grey, with irregular brown spots on the outer webs ; the ex- 
tremity brown. In this last state it is the Sea-Eagle of Pennant, Brit. ZooL i. 
167.; the Halisetus and Pygargus of WiUoughby; and the Vultur albicilla 
and F. ossifragus of Linnaeus, all which belong to this species, and seem to be in 
intermediate stages of plumage. Feeds on fish, aquatic birds, and land animals. 
The following device for catching the eagle is said, in the Statist. Account, 
voL xxi. p. 221., to be successfudy practised in Sutherland. The fox, it is 
added, is readdy secured by the same snare. “ A miniature house, at least the 
wad part of it, is budt on ground frequented by the eagle, and an opening 
left at the foot of the wad sufficient for the egress of the bird. To the out- 
side of this opening, a bit of strong skainy (cord) is fixed, v.^ith a noose formed 
on one end, and the other end returning through the noose. After ad this 
operation is finished, a piece of carrion is thrown into the house, which the 
eagle finds out and perches upon. It eats voraciously ; and, Avhen it is fuUy 
satiated, it never thinks of taking its flight immediately upwards, unless dis- 
turbed, provided it can find an easier way to get out of the house ; for it ap- 
pears that it is not easy for it to begin its flight but in an oblique direction ; 
consequently, it walks deliberately out at the opening left for it, and the 
skainy being fitly contrived and placed for the purpose, catches hold of, and 
fairly strangles it.”
