The most interesting characteristic of this little tree-dweller is its unique habit of gliding from tree to tree through the air. In launching its “flight” the squirrel leaps into space from its perch on a dead snag or tree, extends the fore and hind legs, spreading the loose fold of skin along its sides, and with the flat tail fluttering behind, sails obliquely downward, alighting on the ground or the lower trunk of another tree. This aerial maneuver cannot truly be called flight, but has resulted in the name “flying squirrel.” Little is known of the life history of this beautiful little animal, because of the difficulty of observation. Old woodpecker holes or natural cavities in trees are favorite nesting places, and the flying squirrel is almost never found away from the nest except at night or when disturbed. It is a shy and retiring creature, preyed upon by owls, martens, weasels, and other small carnivorous animals on the rare occasions when it comes to the ground. Flying squirrels are omnivorous, nuts and other vegetable foods are apparently preferred, although meat is sometimes taken when available. CASCADE PIKA, CONY _Ochotona princeps brunnescens_ Howell This small, rodent-like animal is robust, short-legged, with a tail so short that it is not noticeable in field observation. The sexes are colored alike; gray-brown above, whitish below, ears darker, feet light. The pelage is soft and quite dense. In general appearance the pikas closely resemble the rabbits, except for their small size, short legs, and short, rounded ears. The peculiar “bleating” call is unmistakable. _Specimens in park collection:_ RNP-12, RNP-13, and one mounted specimen; Headquarters Museum, Longmire. The many sub-species of the pika are widely distributed at the higher elevations throughout the Rocky Mountains and the Coast Ranges. The typical habitat is the rock-slides and talus slopes near forest line. In the park one may expect to find the pika on any rocky slope from 3,000 (rarely lower) to 8,000 feet. They are infrequently seen in winter, due to the depth of snow over most sites which they inhabit, but during clear, sunny days they occasionally venture out in exposed locations. The common name “hay-maker” has often been applied to the pika, because it is one of those provident creatures which literally “makes hay” during the summer months, curing and drying a wide variety of grasses and other plants which are stored for winter food. The hay-barn of the pika is in a sheltered crevice or beneath an overhanging boulder in the masses of rock where it makes its home. These hay-piles are much in evidence where pikas are abundant.
