Belding's Ground Squirrel is a small, reddish-tan ground squirrel of high-mountain meadows in the Sierra Nevada and Great Basin ranges, famous in behavioral ecology for its nepotistic alarm-calling behavior—females give alarm calls more readily when close relatives are nearby. It has been extensively studied by Paul Sherman and colleagues for its cooperative behavior and kin-selection dynamics. This squirrel hibernates for up to eight months at high elevations.
