Arizona is home to four main squirrel species: the rock squirrel, Abert's squirrel, Arizona gray squirrel, and antelope ground squirrel. Start your search in the central mountains for Abert's, desert grasslands for rock squirrels, and pine forests for Arizona grays. Look for telltale signs like chewed pine cones or tree cavities.

Arizona is home to four main squirrel species: the rock squirrel, Abert's squirrel, Arizona gray squirrel, and antelope ground squirrel. Start your search in the central mountains for Abert's, desert grasslands for rock squirrels, and pine forests for Arizona grays. Look for telltale signs like chewed pine cones or tree cavities.

1. What are the different types of squirrels found in Arizona?

The four main species are the rock squirrel (large, gray-brown, prefers rocky canyons), Abert's squirrel (black or gray with long ear tufts, lives in ponderosa pine forests), Arizona gray squirrel (gray with white belly, found in oak and mixed forests), and antelope ground squirrel (small, white stripes on back, common in deserts). Each has distinct field marks and habitat preferences.

See ourstate wildlife pagefor the next step.

2. Where in Arizona are you most likely to see each species?

Rock squirrels are common across most of the state, especially in rocky areas and canyons. Abert's squirrels are most often seen in the central and northern ponderosa pine belt, around Flagstaff and the Mogollon Rim. Arizona gray squirrels stick to higher-elevation oak and pine forests in the southeastern mountains, like the Santa Rita and Chiricahua ranges. Antelope ground squirrels are widespread in the Sonoran and Mojave deserts, often spotted darting between creosote bushes.

See ourSquirrels guidefor the next step.

3. When is the best time of year to spot squirrels in Arizona?

Spring and early summer are prime time because squirrels are more active gathering food and mating. Late summer into fall is also excellent as they prepare for winter by storing seeds and pine cones. Winter can be slow at higher elevations, but desert species like antelope ground squirrels remain active year-round if temperatures are mild. Early morning and late afternoon offer the best odds for sightings.

See ourstate animal guidefor the next step.

4. How can you tell Arizona's squirrels apart from lookalikes?

The antelope ground squirrel is often confused with chipmunks, but it has a longer, flatter tail and lacks a striped face. Rock squirrels are larger and chunkier than ground squirrels. Abert's squirrel's ear tufts are unique. Arizona gray squirrels can be mistaken for eastern gray squirrels, but they have a more muted gray tone and never have a reddish tinge. Always check tail shape and color: rock squirrels have a bushy tail, antelope ground squirrels have a narrow tail.

5. What are the best tips for finding squirrels in the wild?

Listen for rustling leaves or the sound of falling pine cone bits. Look for middens (piles of chewed cones) under ponderosa pines for Abert's squirrels. In the desert, scan open areas near rock piles for rock squirrels. Bring binoculars to spot movement high in trees. Walk slowly and pause often. Most squirrels will freeze or move only when they feel safe.

6. What squirrel-themed gear should you consider for your wildlife outings?

After a day of spotting, you might want to show off your squirrel appreciation. The **Wild Wings Wildlife T-Shirt Gray Squirrel Unisex Graphic Tee** is a comfortable choice for casual outings.

7. Are there any other common rodents confused with squirrels in Arizona?

Yes, chipmunks and ground squirrels are frequently mixed up. Arizona has several chipmunk species, but they have prominent stripes on the face, while antelope ground squirrels have stripes only on the back. Round-tailed ground squirrels also resemble small antelope ground squirrels but lack the white side stripes. Rock squirrels can be mistaken for prairie dogs, but prairie dogs have a shorter, less bushy tail and are colonial.

8. What is the conservation status of Arizona's squirrels?

Most Arizona squirrel species are stable and common. The Arizona gray squirrel is a species of least concern, but its habitat is fragmented. Abert's squirrel is abundant in ponderosa pine forests. The antelope ground squirrel is widespread and resilient. No species is currently threatened or endangered in the state, but habitat loss from development and fire is a potential risk for forest dwellers.

9. Frequently asked questions about squirrels in Arizona

**Q: Do squirrels hibernate in Arizona?** A: No, Arizona squirrels remain active year-round. Some may become less active in winter but do not truly hibernate.

**Q: What is the largest squirrel in Arizona?** A: The rock squirrel, weighing up to 2 pounds, is the largest.

**Q: Are there any all-white squirrels in Arizona?** A: Rarely, leucistic or albino squirrels appear, especially in urban areas, but they are not a separate species.
