BIRDS OF UPPER PEGU. 25 



27 bis.— Aquila mogilnik, Gm. A. bifasciata, Gray. 



A single nnsexed specimen of the Plain-brown Imperial Eagle > 

 with the buffy occipital patch just beginning to show, has been 

 sent me by Mr. Oates; wing, about 22 - 5. In regard to this 

 Mr. Oates remarks : " I have seen no other specimen ; this was 

 given me by Feilden in the flesh." Captain Feilden remarks : 

 " The Imperial Eagle in Burmah appears to me to differ from the 

 Indian variety, in wanting the orange buff head described by 

 Dr. Jerdon. I have seen eight or ten of these birds in a day, at 

 perhaps a hundred yards' distance, on an average, and never saw any 

 trace of paling on the neck or head; feet, cere, and gape, wax yellow; 

 eyes, bright, sparkling brown. The feet appear to me smaller 

 than in the Indian bird, and the bird throughout less strongly 

 built. I have found these birds singly, or in twos and threes, 

 seated on large trees growing in the long but broken expanse of 

 rice fields extending from Thayetmyo to Mingdoon, enclosed by 

 spurs of the Arracan Mountains. It is almost impossible to 

 get these birds, as the trees they occivpy are generally single, with 

 no cover near them.'" 



I suspect that Aquila amnrensis, Swinhoe, (Proceedings, Zoo- 

 logical Society, 1871, p. 338,) is nothing more nor less than 

 this bird.* 



28.— Aquila clanga,t Pcdl. 



No specimens of this species have been sent me, and Mr. Oates 

 obtained none ; but Captain Feilden's remarks leave no possible 

 doubt as to the species he refers to. 



Captain Feilden says : " The few of these birds that I have 

 obtained have been all in the nearly black unspotted stage, with 

 tarsi more or less white. Food, always fish or frogs, except that 

 the stomach of a one-legged bird in very bad condition contained 

 a bandicoot, which he had probably picked up dead/'' 



31.-~Nisaetus pennatns, Gm. 



This species must be comparatively rare in Upper Pegu. Mr. 

 Oates appears never to have procured it. A single specimen sent 

 by Captain Feilden is precisely similar to Indian birds. Dimen- 

 sions given by Captain Feilden of males, though somewhat smaller 

 than what Jerdon gives, correspond exactly with my own dimen- 

 sions of males. The bird sent is the mature bird in the brown 

 plumage. 



Captain Feilden says : " I have found these birds in the same 

 line of rice fields as the Imperial Eagle, but have only obtained 



* Mr. Sharpe has since confirmed this supposition. 



t By clanga, I mean the bird which we have most of us heretofore callpe 

 noma, Briss. I agree with Mr Brooks that the true ncevia is either identical 

 with or very closely alied to haslata.
