100 Mr. H. E. Dresser's Notes on 



/3. A. intermedia (ad. A. chrysaetos), SevertzofF, p. 63. 



This form of the Golden Eagle, which I can scarcely re- 

 f^ard as being even a true subspecies, has the same vertical range 

 as the A, fulva above referred to ; but its horizontal range is 

 given as follows : " resident in districts III. and IV.^' Mr. 

 SevertzofF speaks of it (p. 112) as Aqui/a fulva, var. inter- 

 media, and writes as follows : — " The small feathers of the 

 plumage are similar in colour to those in Aqiiila chrysaetos ; 

 but it has the white at the base of the tail, and the quills as 

 in Aquila fulva. This species was met with in the salt plains^ 

 where it also breeds. In the Thian-shan mountains I only 

 met with typical A. fulva {A. nobilis, Pall.). I may here 

 observe that in the Southern Ural both forms of Aquila fulva 

 occui' {Aquila nobilis. Pall., and A. intermedia) , and Aquila 

 chrysaetos ; but in the neighbourhood of St. Petersburg, where 

 I frequently saw A. nobilis and A, chrysaetos, I scarcely ever 

 met with A. intermedia." 



10. Aquila heliaca, Savigny. 



Aquila imperialis, Severtzoflf, pp. 63 & 112. 



Horizotital range. Is found during the summer and breeds 

 in districts I. and II., — and besides breeding in district III., 

 is found there in the winter also. 



Vertical range. In district 1 it is resident ; in district 2 it 

 has been observed both in the summer and the winter ; and 

 in district 3 it occurs during passage, and may possibly some- 

 times remain to breed there. Severtzoflf gives (p. 112) the 

 following additional notes respecting this Eagle, viz. : — 

 '' During summer it is found in all parts of Turkestan, but 

 breeds only in the salt plains near Jorteck. During the 

 breeding-season it is only found near its breeding-haunts, but 

 frequently wanders and changes its residence during the win- 

 ter. Like other Eagles, it breeds only every alternate year. 

 So soon as the young are full-gro^vn they commence to change; 

 but the plumage changes very slowly. During the winter the 

 moult is arrested, and recommences in the spring of the fol- 

 lowing year ; and they never breed whilst this moult is pro- 

 gressing. I purpose going more fully into this question in
