Collared Pika - Ochotona collaris
The collared pika (Ochotona collaris) is a species of mammal in the pika family, Ochotonidae, and part of the order Lagomorpha which comprises rabbits, hares, and pikas. It is a small (~160 gram) alpine lagomorph that lives in boulder fields of central and southern Alaska (U.S.), and in parts of Canada, including northern British Columbia, Yukon, and western parts of the Northwest Territories. It is closely related to the American pika (O. princeps), but it is a monotypic form containing no other recognized subspecies. It is asocial, does not hibernate, and spends a large part of its time in the summer collecting vegetation that is stored under rocks ("haypiles") as a supply of food for the winter. Some individuals have been observed collecting and consuming dead birds as sources of fat and protein. Thousands of trips are made during July and August to collect vegetation for winter.

Northern Grasshopper Mouse - Onychomys leucogaster
The northern grasshopper mouse (Onychomys leucogaster) is a North American carnivorous rodent of the family Cricetidae. It ranges over much of the western part of the continent, from central Saskatchewan and central Washington to Tamaulipas in northeast Mexico. The northern grasshopper mouse is found in North America, but primarily in dry areas. They are similar in body size to other mice; on average they are 164 mm (6.5 in) long and about 35 g (0.077 lb) in weight. The tail is most often less than 30% of the total body length, whereas other mice tend to have longer tails adding to long body lengths. Unlike most rodents, this one has a mostly carnivorous diet mainly consisting of small insects, other mice, and even snakes; no more than a quarter of its diet is plant-based. This rodent is also nocturnal. Throughout the night, the grasshopper mouse makes high-pitched noises to claim its territory.
