26 A FIRST LIST OF THE 



them on the general parade ground at Thayetmyo. I have 

 never obtained a female, but once or twice saw a much paler 

 bird that must have been either the female or young-. I have 

 always found them, when perched, seated in the centre of mode- 

 rate-sized trees in full foliage. The stroke of the wing of this bird 

 is much more rapid than is the case in the flight of the other 

 eagles. This bird appears to hunt its own game down, and 

 never touch carrion. The two that I shot contained a White-headed 

 Myna and a field rat ; another that I hit and lost, was eating 

 some other bird. These birds are tame, and can be shot by walk- 

 ing past them in a careless manner ; but they are not so stupidly 

 tame as the Indian variety often is. I never saw any trace of the 

 Pale-head. The pale birds that I saw appeared to resemble the 

 adult Tawny Eagle hi color. I never heard it utter any note."

 He remarks : "Having now secured three specimens, I am begin- 

 ning to think that the bird is commoner than I once considered it." 

 Captain Feilden says : " This seems to be a very common 

 bird about Thayetmyo; every ravine in the spurs of the 

 Arracan Mountains seems to contain one or more pairs, as 

 well as every wooded stream in the lower ground. Their wild 

 screaming (whistle) is almost always to be heard long before 

 the bird is seen, as it sits on some large tree rising above the rest 

 of the jungle or wheels in circles far overhead; it is one of the
