WILD AN'IMALS OF GLACIER KATIONAL PARK. 



MacFaklake Screech Owl: Otiis cislo macfarlanel. — A mounted 

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

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

 quavering crj^ should be listened for at night hy campers along the 

 edges of the park. 



"Western Horned Owl: BuIjo virginianus occidentalis. — The 

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

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

 in caverns 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 over the Swiftcurrent at 

 Many Glaciers, and at manj^ 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 

 rlrginianus subarcticus. — In the 

 winter of 1916-17, Mr. Bryant 

 reports, so many Arctic horned 

 owls were seen that " it seemed 

 like a flight." Every few years, 

 he saj's, the owls come in num- 

 bers. 



Snowt Owl: Nyctea nyc- 

 tea, — The circumpolar hornless 

 snowy owls, pure white, or 

 white marked with black, some 

 of which come into the United 

 States in the Avinter, have been 

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

 park. In the winter of 1910-17, Mr. Brj'ant says, quite a number 

 were seen. 



Hawk Owl: Smmia ulula caparocJi. — The hawk owl, which 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 bright 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 are closely barred.

 Greek, on August 9 we saAV what Mr. Bailey took for a hawk owl, a
