A male with greatly enlarged gonads had the irides golden-yellow ; 

 the eyelids edged fulvous; the cere dull brown; the maxilla greenish 

 horn, with tip and edges of the commissure horn-color ; the mandible 

 horn, tipped greenish ; the toes grayish flesh ; the claws with the basal 

 half light gray, otherwise horny brown. A female with inactive 

 gonads had the irides rich brown ; the bill horn ; the toes light brown ; 

 the claws horn. Greenway's juvenile male had the irides yellow; the 

 bill light gray ; the toes blue-gray. 



This is a rather larger bird than our other scops owls. In one 

 phase it has the general coloration buffy brown, paler below, every- 

 where mottled and vermiculated with blackish, vivid buff, and buffy 

 white; the forehead, superciliary region, outer portion of scapulars, 

 and a broad but poorly defined nuchal collar vivid buff. Another 

 phase has the general color grayish brown and the vivid buff replaced 

 by brownish white. 



The collared scops owls of Asia are, in my opinion, only subspe- 

 cifically distinct from the North American forms grouped under the 

 name Otus asio. As early as 1874 this was apparent to Kobert Kidg- 

 way, who (apud Baird, Brewer, and Ridgway, A history of North 

 American birds, vol. 3, pp. 55-56) discussed at some length the close 

 resemblance between Otus kennicottii (Alaska) and Otus semitorques 

 (Japan) and suggested the probability that "the latter is also a mere 

 geographical form" of O. asio.

Gyldenstolpe obtained an example of this eagle owl at Khun Tan 

 in 1914 and saw one other in the vicinity ; he observes that "both these 

 specimens occurred in a mixed pine and oak-forest at a fairly high 

 altitude." The bird recorded by Greenway was taken on Doi Ang 

 Ka at 4,300 feet, April 8, 1937. 



This is a very large, horned species, with brown irides and yellow 

 bill. It has the upperparts deep brown, most of the feathers edged 

 or mottled with white or pale buff, especially on the wing coverts, 

 scapulars, and lower back ; the tail banded with buffy white and deep 

 brown; the entire underparts white, suffused with buff, more or less
