Yes, squirrels are found throughout Colorado, with several species including the fox squirrel, Abert's squirrel, and pine squirrel. The best place to start is your local park or foothills, especially in the early morning or late afternoon. Look for ear tufts on Abert's or a rusty belly on fox squirrels.
1. What are the most common squirrel species in Colorado?
Colorado hosts four main squirrel species: the fox squirrel (large, rusty belly, often in towns), Abert's squirrel (black or gray with ear tufts, in ponderosa pine forests), pine squirrel (small, reddish, in conifer forests), and the rock squirrel (ground-dwelling, mottled brown, in rocky areas). Each has distinct field marks that make identification straightforward once you know what to look for.
In Colorado, squirrels sightings usually improve when you slow down and match your first stop to the most useful ID markers and likely lookalikes. Use thestate wildlife huband theroute guideto narrow your first area, then check access, weather, and distance before you settle in. A short walk with one clear viewing plan often beats covering too much ground, especially when habitat changes fast from open edges to brush, wetlands, timber, shoreline, or neighborhood cover.
2. Where in Colorado do people most often spot squirrels?
Your best odds are in urban parks and neighborhoods – places like Denver's City Park or Boulder's Chautauqua Park have reliable fox squirrel populations. In the foothills and mountains, look for Abert's squirrels around ponderosa pines at elevations up to 10,000 feet. Start with any area with mature trees, especially oaks or pines, and you'll likely see one within minutes.
3. What time of year are squirrels most active and easiest to identify?
Spring and fall are peak seasons. In spring (March to May), squirrels are out gathering food and courting, often in open areas. In fall (September to November), they busily cache nuts and are very visible. Morning hours (7-10 am) and late afternoon (4-6 pm) offer the best chances, as squirrels rest during the heat of midday.

4. How can you tell a fox squirrel from an Abert's squirrel?
Size and ear tufts are key. Fox squirrels are larger (18-27 inches including tail) with a rusty orange belly and no ear tufts. Abert's squirrels are smaller (16-22 inches), have prominent ear tufts (especially in winter), and a white belly. Abert's also have a distinct dark stripe down the back, while fox squirrels lack that stripe.
5. What field marks should you look for when identifying squirrels?
Focus on three things: belly color, ear tufts, and tail shape. Fox squirrels have a rusty belly, broad bushy tail. Abert's squirrels have a white belly, black or gray back, and long ear tufts. Pine squirrels are small, reddish-brown with a pale belly and a narrow tail. Rock squirrels are ground-dwelling with a long, less bushy tail and mottled pattern.
6. What are the best locations in Colorado for squirrel watching?
Start with your nearest city park – places like City Park in Denver, Palmer Park in Colorado Springs, or the trails at Roxborough State Park near Littleton. In the mountains, the ponderosa pine forests of Pike National Forest or around Rocky Mountain National Park's lower elevations are reliable. For a guided search, check outColorado wildlife viewing areas.
7. What gear can help you enjoy squirrel spotting?
A simple pair of binoculars (8x42 works well) and a field notebook are all you need. Another way to bring the adventure home is with a great t-shirt. Check out theSquirrel Lover Vintage T-Shirtfor a subtle homage, or theWild Wings Wildlife T-Shirt Gray Squirrelfor a detailed illustration. Browse allwildlife-themed shirtsfor more options.

**Are there any rare squirrel species in Colorado?** The Abert's squirrel is considered a species of concern in some areas but is still relatively common in suitable habitat. **Do squirrels hibernate?** Only ground squirrels hibernate; tree squirrels (fox, Abert's, pine) remain active year-round but are less visible in deep snow. **What is the best way to attract squirrels to my yard?** Provide a feeder with black-oil sunflower seeds and a water source.
