This is a very large species which exhibits great individual varia- 

 tion in coloration. An adult example in Washington has the general 

 plumage light brown; the primaries blackish; the blackish brown 

 secondaries and the greater wing coverts tipped fulvous-white, giving 

 the appearance of two narrow, light wing bars ; the upper tail coverts 

 tipped fulvous-white: the tarsi feathered to the toes; the nostril 

 elliptical, higher than broad.

 sia and Siberia to Kamchatka). 



Aquila nipalensis, de Schauensee, Proc. Acad. Nat. Sci. Philadelphia, 1929, p. 

 577 (Chiang Mai). 



Aquila nipalensis nipalensis, Deignan, Journ. Siam Soc. Nat. Hist. Suppl., 1931, 

 p. 165 (Chiang Mai) ; 1936, p. 77 (Chiang Mai). 



A male taken by de Schauensee at Chiang Mai, December 20, 1928, 

 is the only definite record for our area. 



This specimen had the irides brown, mixed with yellow ; the apical 

 half of the maxilla black and the basal half gray-green; the cere 

 olive-yellow, brighter at the rictus ; the claws black. 



Adults are in general dark chocolate-brown. Immature birds dif- 

 fer in having the upper tail coverts mixed with brownish white ; the 

 upper wing coverts with brownish white or light brown tips; the 

 ends of the secondaries mottled with light brown or brownish white, 

 which sometimes forms a broad wing bar; the underparts streaked 

 everywhere with light brown. The tarsi are feathered to the toes 

 and the nostril is round, as broad as high. 



De Schauensee and I have reexamined together the specimen upon 

 which his record of A. nipalensis was based and agree that it must be 

 referred to clanga.
