# Belding's Ground Squirrel (*urocitellus beldingi*) Belding's ground squirrel is a charismatic, social rodent native to the high-elevation meadows and grasslands of the western United States. Highly active during the brief alpine summer, these busy creatures are well known for their upright sentinel postures, standing tall on their hind legs to scan the horizon for predators. Their vocalizations—a series of sharp, high-pitched whistles and trills—serve as a sophisticated alarm system to warn family members of incoming threats. This social structure and cooperative vigilance make them a fascinating species to study. They spend the vast majority of the year in deep underground burrows, where they undergo a prolonged winter hibernation that can last up to eight months. - **Category:** [Mammals](https://www.snappit.app/explore/categories/mammal) - **Rarity:** Common - **Danger:** 1/5 · Very low - **Snaps:** 5 - **Habitat:** Typically found in high-altitude mountain meadows, sagebrush flats, and grassy pastures of the western United States. ![Belding's Ground Squirrel](https://inaturalist-open-data.s3.amazonaws.com/photos/711712219/medium.jpg) Photo: CC0 · [iNaturalist](https://www.inaturalist.org/photos/711712219) ## Appearance This medium-sized ground squirrel measures about 20 to 30 centimeters in length and features a relatively short, flat tail. Its coat is a blend of grizzled brownish-gray on the back, shifting to a buff or reddish-yellow on the underside. A key identifying feature is its grayish-white eye-rings and a subtle, reddish-brown stripe running down the middle of its back. They have small, rounded ears that lie close to the head and sturdy, clawed limbs adapted for rapid digging. ## Taxonomy - **Kingdom:** Animalia - **Phylum:** Chordata - **Class:** Mammalia - **Order:** Rodentia - **Family:** Sciuridae - **Genus:** Urocitellus ## Interesting facts - Belding's ground squirrels spend up to 70% to 80% of their lives asleep or hibernating underground. - They are known to engage in 'kissing' as a form of greeting and identification when they meet near their burrows. - They exhibit nepotism in their alarm calls; females are far more likely to sound the alarm if they have close female relatives nearby, risking their own safety to warn kin. ## Special abilities - **Vigilant Sentinel Posting:** Standing tall on their hind feet, these squirrels act as guards, scanning the sky and ground for predators and signaling danger with high-pitched chirps. - **Extreme Deep Hibernation:** To survive harsh alpine winters, they enter a state of torpor for up to eight months a year, drastically reducing their heart rate and body temperature. - **Subterranean Architect:** They construct complex, multi-chambered burrow systems with separate areas for nesting, food storage, and waste. ## Measurements & details - **Length:** 20-30 cm - **Weight:** 0.2-0.5 kg - **Lifespan:** 3-6 years - **Speed:** 25 km/h - **Clutch Size:** 3-8 - **Incubation:** 23-28 days ## Diet & Feeding Primarily herbivorous, feeding on a wide variety of green vegetation, seeds, and flowers, but they will readily supplement their diet with insects and carrion. - **Age differences:** Juveniles focus more on tender green vegetation and high-energy seeds, whereas adults consume massive quantities of diverse vegetation to build fat reserves for hibernation. - **Primary Foods:** Meadow grasses, Wildflower seeds, Insects, Roots and tubers, Fungi - **Foraging Method:** Foraging ## Ecological connections - **Eaten by:** [American Badger](https://www.snappit.app/explore/american-badger) (*Taxidea taxus*) — Hunted by the American Badger, which often digs out the squirrel's burrows. - **Eaten by:** [Prairie Falcon](https://www.snappit.app/explore/prairie-falcon) (*Falco mexicanus*) — Preyed upon by the Prairie Falcon from the air during the summer months. - **Competitor:** Golden-mantled Ground Squirrel (*Callospermophilus lateralis*) — Competes for grassy forage and nesting space in alpine meadows. ## Safety **Danger:** 1/5 · Very low No special safety notes yet. ## Frequently Asked Questions ### How to identify Belding's Ground Squirrel?
