BIUDS OF BEITISH BURMAH. 
Length 30 inclies^tail 11*5^ wing 22, tarsus 3*5^ bill from gape 2*8^ cere 
•85. The female is a little larger. 
It has been shown that the name of A. mogilnik is properly referable to 
the Imperial Eagle ; and Mr. Gurney agrees with Mr. Dresser in considering 
the name of A. nipalensis the correct one for the present species. Both 
A. bifasciata and A. nijmlensis apply to the same bird, and the former 
name is senior by a year. The Steppe-Eagle has long been confounded 
with the Imperial Eagle,, and I therefore do not give any synonyms which 
apply to both species. 
A. mogilnik, when adult, is of a dark blackish brown, with some of the 
scapulars white, and the yonng birds are lineated. 
The Steppe-Eagle is not uncommon in Burmah as a winter visitor. 
Capt. Feilden states that it is very common at Thayetmyo, but I cannot 
say that I ever found it so. Further south, however, near Pegu and on 
the banks of the canal, I generally succeeded in shooting three or four 
specimens every winter. Mr. Davison notes its occurrence in Tenasserim 
both at Moulmein and Tavoy. 
It has a considerable range^ being found in Eastern Europe, Southern 
Asia, China and Eastern Siberia. It appears to be more or less mi- 
gratory. 
This Eagle is a heavy dull bird; and the specimens I procured were 
generally seated on the ground, allowing me to approach within gunshot 
without difficulty.
