Overview
The Collared Pika (Ochotona collaris) is an industrious, cold-adapted alpine lagomorph native to the rugged, glaciated mountain ranges of Alaska and northwestern Canada. Characterized by its soft greyish coat highlighted by a distinct pale collar band across its shoulders, this miniature high-altitude relative of rabbits thrives on windswept alpine rock slides, famous for spending its short subarctic summer gathering fragrant ‘haypiles’ of dried alpine herbs.
Biology and Physical Characteristics
Ochotona collaris has a compact, egg-shaped body with short, rounded ears, no visible external tail, and dense, soft fur that provides superior thermal insulation against brutal subarctic blizzards. Its dorsal coat is frosted grey-brown, set off by a distinctive collar of pale grey fur wrapping around the neck and shoulders. Its furry foot pads provide dependable traction across icy boulders.
Behavior and Ecology
Unlike many northern alpine mammals, the Collared Pika does not hibernate during winter. Instead, it spends the brief subarctic summer frantically harvesting leaves, alpine flowers, and sedges, laying them out on sunlit rocks to cure into hay before storing them in sheltered rock crevices beneath the snow. During the long, dark winter, it tunnels through the subnivean space beneath deep snowdrifts, feeding on its cured caches.
Conservation and Human Impact
Assessed as Least Concern by the IUCN, the Collared Pika remains widespread across protected wilderness in Denali and Wrangell-St. Elias national parks. However, because it is strictly adapted to cold microclimates and cannot tolerate high summer temperatures, it serves as a sensitive bioindicator of climate warming across subarctic alpine tundra ecosystems.
Interesting Factoid
Collared Pikas act like miniature mountain farmers: during the fleeting subarctic summer, an individual pika can make over 5,000 harvesting trips across talus rocks to build a personal haypile weighing up to 6 kilograms.
