42 WILD ANIMALS OF GLACIER NATIONAL PARK, 



The five or six young are born late- in May or early in June. By 

 the first of July they are out playing and learning the ways of chip- 

 munk world, and by August they, too, are busy storing away winter 

 supplies. Occasionally in their eager search for food they appro- 

 priate camp suj)plies not intended for them, but in* most cases they 

 are welcome visitors to camp, and their spritely ways and cheery 

 chipper along the trails add one more bright and attractive phase 

 to the animallife of the park. 



Forest CiiiP^NruxK: Evfnm'taf; iimhrinus felix (Rhoads). — These 

 large, bushy-tailed, white-bellied cliipmunks are readily distin- 

 guished from the 3'ellow-bellied by their slightly larger size and 

 richer colors, in strong contrast to their pure white bellies. Mainly 

 forest dwellers, they climb trees readily, and if frightened often go 

 up a tree instead of down into the ground. Their voices also are 

 sharper, more shrill, and birdlike, both, in their slow chi'p! chip! 

 chip! and in their rapid and sometimes frantic chipper of alarm. 

 They are not abundant and are seen only occasionally, generally in 

 the Canadian Zone forest of the middle slopes of the park. In 1895 

 s]ie('imens were collected along the- south side of St. Mary Lake, and 

 others were taken at. Summit and Paola. In 1917 one was found 

 living among the ruins of the old chalet at the. lower end of Gun- 

 sight Lake, but even in this mass of ruins when alarmed it took 

 I'ef uge in a spruce tree near by. Forest chipmunks seem less friendly 

 than the abundant little yellow-bellied spee-ies, but this is doubtless 

 due to their scarcity and lack of frequently coming in touch with 

 people. The. four or five young are born in June, and the same cycle 

 of breeding, storing food, and sleeping through the long winters is 

 gone through each year. 



Little ISIouxtaix Chipmunk : Eutamias oreocetes Merriam. — 

 This tiny chipmunk, pale-yellowish with pure white belly, is appar- 

 ently common at timberline along the crest of the range throughout 

 the park. The type specimen was collected in 1895, at 7,500 feet, 

 on the high ridge, north of Summit Station on the Great Northern 

 Railroad, and in 1917 two more were taken in Piegan Pass at 7,400 

 feet altitude, and others were seen in Gunsight Pass at 7,500 feet. 

 All of those collected and others seen have been at or near the ex- 

 treme ujjper limit of dwarf tree grow^th or on slopes several hundred 

 feet above. They are usually found among the rocks, scampering 

 over them like tiny nervous sprites, never still for a moment, flashing 

 from one stone or little alpine plant to another, or dashing in and 

 out among rocks or under prostrate branches of dwarfed trees. In 

 Piegan Pass I followed one for some distance as it ran over the rocks, 

 apparently with some distant object in view, until it came to a little 

 creek that emerged from under a great snow bank. It quickly dis-
