THE GREY-FACED BUZZARD-EAGLE. 197 



barred with black ; quills chestnut broadly tipped with dark brown, and a 

 portion of the inner webs margined with white ; the inner webs of the 

 primaries and both webs of the secondaries barred with dark brown; 

 wing-coverts mixed rufous and white ; under wing-coverts pale chestnut 

 barred with brown. 



The female is like the male, but the rump is of a duller chestnut and the 

 head and nape are darker. 



The plumage does not vary much in this species ; the colours increase 

 in brilliancy with age, and the bars on the tail, which are very distinct in 

 the young bird, become much interrupted in the adult. In the young the 

 white bars extend to the middle of the abdomen; the edge of the wing is 

 white; the breast is brown, and the throat, lores, and forehead nearly 

 pure white ; the crown is rufous with dark brown stripes ; and the whole 

 plumage, where grey in the adult, inclines to brown in the young. 



Eyelids and skin over the eye orange-yellow ; iris yellow ; gape, bill 

 and cere orange ; the tips of both mandibles brown ; mouth flesh-colour ; 

 legs yellow; claws dark horn. 



Length 15*5 inches, tail 6, wing 11, tarsus 2'5, bill from gape T35. 

 The female is rather smaller than the male, and not, as might be expected, 

 larger. 



The Grey-breasted Buzzard-Eagle is abundant over the whole of Pegu. It 

 appears to be somewhat rare in Tenasserim, and Mr. Davison did not observe 

 it south of Amherst, nor did Capt. Bingham meet with it further east 

 in the Thoungyeen valley. 



It occurs in Siam, and it has been recorded from Java, Timor, Borneo 

 and Celebes. 



This richly- coloured bird frequents the same sort of jungle as the pre- 

 ceding, being found in open country and the banks of rivers. It feeds on 

 snakes and crabs. I found the nest in March on two occasions small 

 structures of sticks placed in low mango trees and containing two eggs, 

 which were pale greenish white in colour.
