198 BIBDS OF BRITISH BURMAH. 



the latter of which are plainly barred and broadly tipped with pure white ; 

 forehead white ; sides of face clear ashy grey ; sides of neck ashy brown, 

 uniform with the interscapulary region ; wing-coverts rufous - brown, 

 mottled with clearer rufous ; primary-coverts rufous, externally mottled 

 and broadly tipped with black ; quills rufous, narrowly tipped with buffy 

 white; primaries brown externally and towards their tips, also barred 

 with dark brown on their inner webs; the secondaries ashy brown, 

 inclining gradually to whity brown at their tips, washed with rufous and 

 barred with dark brown ; the lower surface of the wing creamy white on 

 the inner webs of the quills, somewhat washed with rufous ; tail ashy 

 brown, whity brown at tip and crossed with three or four broad bars of 

 blackish brown ; the lower surface ashy white, the bars showing more 

 plainly, except on the outermost feather, where they are obsolete ; throat 

 white, with a mesial, line of ashy brown, as well as two not very distinct 

 moustachial streaks ; upper breast ashy brown washed with rufous ; the 

 lower breast and abdomen barred with white and rufous-brown, the latter 

 bars decreasing towards the vent and thighs and totally absent on the 

 under tail-coverts ; under wing-coverts with slight cross markings of pale 

 rufous. (Sharpe.} 



In younger birds the cheeks and ear-coverts are a darker grey ; the 

 occiput, nape and sides of the neck are dark grey-brown streaked with 

 rufous ; the mantle is a nearly pure hair-brown ; the throat is much more 

 tinged with buff; the breast is darker and more mottled; and the rusty 

 rufous is wanting on the wing. 



In a still younger bird the entire crown, occiput, nape and sides of the 

 neck are mingled darker and lighter brown, ferruginous and buffy white, 

 and the cheeks are streaked with white and the ear- coverts are streaked 

 paler ; the feathers of the breast are buffy white with lanceolate rufous- 

 brown shaft-stripes ; the brown of the abdomen is darker ; and the bars on 

 the tail are much less conspicuous, while the bars on the tibial plumes are 

 almost heart-shaped. (Hume.) 



The irides bright yellow; legs and feet bright yellow; claws black; 

 cere, gape, greater portion of lower mandible, upper mandible to O25 

 beyond nostril and eye -shelf orange-yellow; rest of bill black. (Davison.) 



Length about 17 inches, tail 7'6, wing 13'5, tarsus 2'2, bill from gape 

 1'4. The female is of about the same size. 



The above descriptions, taken from Messrs. Sharpe and Hume's 

 writings, give a very clear idea of the changes of plumage that this species 

 undergoes. 



The Grey-faced Buzzard-Eagle is found in Tenasserim from Amherst 

 southwards, but it does not appear to be anywhere common. My 

 men procured one specimen at Malewoon in the extreme south of the 

 Division.
