Description wikipedia

The American pika (Ochotona princeps) is a small, herbivorous mammal of the family Ochotonidae, closely related to rabbits and hares (order Lagomorpha). It is native to the mountainous regions of western North America, typically inhabiting rocky slopes and talus fields at or above the tree line. Unlike most mammals of similar size, the American pika is diurnal, being active primarily during the day. It employs two distinct foraging strategies: directly consuming vegetation or gathering and storing plant materials in "haypiles" to sustain itself through the winter months, a behavior known as haying. Pikas are vocal animals, using a variety of calls and songs both to warn of approaching predators and during the breeding season. Predators of the American pika include eagles, hawks, coyotes, bobcats, foxes, and weasels. Recent studies suggest that populations in the southwestern United States are declining due to habitat loss and global warming. Despite these regional declines, the American pika is overall assessed as a species of Least Concern by the IUCN and remains common in the northwestern United States and Canada.
