WILD AXIMALS OF GLACIER KATIONAL PARK. 



MacFarlajse Screech Oavl: Otas asio macfarianel. — A mounted 

 specimen of the familiar little horned screech owl from 7^ to 10 inches 

 long may be seen at Lewis's. As it is an owl of the low country, its 

 quaverhig cry should be listened for at night by campers along the 

 edges of the park. 



Western Horned Oavl: Bubo virginianus occidentalis. — The 

 great horned owl should be looked for in the more open parts of the 

 park. Its nests may be found on old hawk nests, in hollow trees, or 

 in caA-erns in the cliffs. It is one of the most spectacular birds of 

 the park. On a moonlight night, one has been seen sitting on the 



bridge OA^er the Swiftcurrent at 

 Many Glaciers, and at many a 

 camp in the mountains the 

 loud hooting has brought a 

 thrill of keen satisfaction to the 

 lovers of the forest. 



Arctic Horned Owl: Bubo 

 virginianus svbarcticus. — In the 

 Avinter of 1916-17, Mr. Bryant 

 I'eports, so many Arctic horned 

 OAvls AA^ere seen that " it seemed 

 like a flight." EA-ery few years, 

 he says, the oaaIs come in num- 

 bers. 



Snoavy Oaa'l: Nyctea nyc- 

 tecu — The circumpolar hornless 

 snowy owls, pure AA-hite, or 

 AAdiite marked wdth black, some 

 of AA'hich come into the United 

 States in the winter, haA'e been 

 seen by Mr. Gird in January and February along the border of the 

 park. In the winter of 1916-17, Mr. Bryant says, quite a number 

 were seen. 



Haavk Oaa'l: Surnia ulula caparoch. — The haAvk oayI, Avhich is a 

 medium-sized northern owl, has been found in Montana in summer 

 and should be carefully looked for. Strictly diurnal, it often watches 

 for its prey from the top of a dead tree in briglit sunlight, and with 

 swift, hawklike flight pitches down from its high perch nearly to the 

 ground, and after capturing its prey rises quickly again to its tree 

 top. Seen close by, its light face is encircled by a heavy black ring, 

 and its underparts ai-e closely barred.
