42 WILD ANIMALS OF GLACIEB 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 theii- eager seai'ch for food they appro- 

 priate camp supplies not intended foi' them, Ijiit in* most cases they 

 are welcome visitors to camp, and their' sjiritcly ways and cheery 

 chijiper along the trails add one more bright and attractive phase 

 to the animal life of the park. 



Forest Chipmunk: Evfamkif; vmhrinus fclix (Ehoads). — These 

 large, bushy-tailed, white-bellied chii^imunks are readily distin- 

 guished from the yellow-bellied b}' 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 

 shar])er, more shrill, and l)irdlike, both, in their slow chip! 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 189.") 

 specimens were collected along thC' south side of St. Mary Lake, and 

 others Avere taken at Summit and Paoja. 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 

 refuge in a spruce tree nearby. Forest chipmunks seem less friendly 

 than the abvnidant 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 Mountain Ciiipjiunk: Euta'muis oreocetes Merriam. — 

 This tiny chipmunk, pale-yelloAvish 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 189.5, at 7,500 feet, 

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

 Eailroad, and in 1917 two more were taken in Piegan Pass at 7,-1:00 

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

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

 ti-eme ujiper limit of dwarf tree growth or on slopes several hundred 

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

 over them like tiny nervous sjn-ites, never still for a moment, Hashing 

 from one stone or little alpine ]5lant to another, or dashing in and 

 out among rocks or under ])rostrate branches of dwarfed trees. In 

 I'iegaii 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-
