76 NORTH AMERICAN FAUNA. [no. 19. 



\Pandion haliaetxiK. caTolinen.n><. American Osprey. While the 

 steamer was anchored near Holy Cross Mission August :25, one of the 

 passengers, Mr. J. F. Burkman, tired at, but failed to get, a large 

 hawk which he was positive was this species. As Mr. Nelson records 

 it from the Lower Yukon, I see no reason to doubt Mr. Burkman's 

 identification.] 



87. Asio accipitrinus. Short-eared Owl. 



We saw a short-eared owl flying overhead at St. Michael on the 

 evening of September 7, and I flushed one from some bushes on Whale 

 Island the next day. September 9 I set three steel traps near St. 

 Michael on poles in the tundra. One of them failed to catch anything, 

 but before September 25 the others yielded short-eared owls and the 

 nails of another. These birds had lieen feeding on mice and shrews. 

 Osgood shot a short-eared owl at Unalaska October 5. These speci- 

 mens average slightly darher^ with the white of the face purer, than 

 fall birds from New England. 



88. Scotiaptex cinerea. Great Gray Owl. 



From some low growth on a steep hillside at Miles Canyon 'luh' 11 

 we flushed a large gray owl that I am confident was this species. We 

 saw a mounted specimen in Dawson August 2 and I was told at 

 Circle that an owl answering the description of this species had been 

 killed there recently. 



89. Nyctala tengmalmi richardsoni. Richardson Owl. 



While l3'ing awake under my mosquito netting in a clearing at the 

 base of the Semenow Hills on the night of July 19 I saw a small, 

 round-headed owl alight on the limb of a dead tree only a few feet 

 away. It flew before I could bring my gun to bear, liut I have no 

 doubt it was this species. Osgood took a young bird near Rink Rap- 

 ids July 22. I was told at Circle that a small owl was common there, 

 and that one had been caught recently. 



90. ? Megascops asio kennicotti. Kennicott Screech Owl. 



A reddish-brown owl, of the size and appearance of a screech owl, 

 was seen by Maddren and mvself at Caribou Crossing on the afternoon 

 of June 27. We were drawn from camp by its peculiar notes, and 

 saw it fly from a poplar across an opening to a spruce thicket. Later 

 that da}^ Osgood caught a glimpse of another, or perhaps the same 

 bird, as it flew from the top of a small poplar. 



91. Bubo virginianus pallescens. Western Horned Owl. 



Owl pellets, some of themi remarkably large, containing chiefly 

 bones of rabbits, ground squirrels, and red squirrels, were found in 

 great abundance, especially at Caribou Crossing and on Windy Island, 

 Lake Tagish, but the most careful hunting failed to disclose the owls.
