Of the fact that the golden eagle is now and has been for centuries commonly trained and flown in Central Asia there is no manner of doubt. Many excellent authorities maintain that it is the species used by the Kirghis and other tribes subject or tributary to Russia under the name of Kholsan. This was also the opinion of M. Paul Gervais, who became the owner of a veritable Kholsan, imported into France by M. Maichin, who purchased it from the Kirghis for £40 and a gun. This trained eagle, which was a female, would take foxes well, and after binding to them was accustomed to grip them by the fore part of the mask, thus obviating the chance of a dangerous bite. In Central Asia the Kholsan is flown at bustard, hare, fox, and antelope; and the females will tackle such heavy quarry as wild goat, wolf, and even wild boar. Berkute (_Aquila nobilis_) About the identity of this species there is even more doubt than about the Kholsan. Mr. Harting inclines to the view that it is no more than a golden eagle in a different phase of its plumage. Others suppose that it is the imperial eagle, and others again regard it as Bonelli's eagle. It appears that in the Russian provinces of Asia it is still more commonly used than the Kholsan, and at much the same quarry, which would suggest the conclusion that it is not at any rate a larger bird than _A. Bonellii_. White-Crowned Eagle (_Haliætus leucoryphus_) A specimen was owned by a Russian falconer, who found it worth while to keep it over two moults, and must have taken a favourable view of its merits. Spotted Eagle (_Aquila clanga_ or _nævia_) This large eagle is trained by the Kirghis, under the name of Kara Gush, _i.e._ black eagle. Imperial Eagle (_Aquila imperialis_) This is a smaller eagle than _A. chrysaetus_, the female measuring about 32 inches and the male about 31. It appears to be susceptible of training, and is thought by many to be included in the list of eagles commonly used in Turkestan. It is found throughout the greater part of Asia, and occasionally in South-Eastern Europe. Steppe Eagle (_Aquila nipalensis_) This bird is described by some naturalists as a hawk-eagle. It is of a taking and sportsmanlike appearance, the eyes of old specimens being of a fiery yellow, though in young birds they are dull grey. Colonel D. Radcliffe obtained several specimens in India, both eyess and wild caught. He says that in the wild state it takes pine martens and also the musk deer. Bonelli's Eagle (_Aquila Bonellii_) Female--Length, 26-1/2 inches; wing, 18-1/4; tail, 11-1/2; tarsus, 4. Male--Length, 24-1/2 inches; wing, 17-1/2; tail, 11-1/4; tarsus, 3.9.
