the latter of whicli are plainly barred and broadly tipped with pure white ; 
forehead white ; sides of face clear ashy grey j 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 websj 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 clecreasiDg 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 0*25 
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.
