As a nature lover who has spent years observing squirrels around the world, I’m often asked about the tree-climbing abilities of their small, striped cousins – chipmunks. Do chipmunks climb trees? Though they may look like miniature squirrels, do chipmunks actually climb trees or are they strictly ground dwellers? The response to this inquiry holds a complexity beyond initial perceptions.
While chipmunks are capable climbers, they prefer to stay close to the ground and only head up a tree when necessary. Their anatomy and behavior point to them being primarily burrowing animals. However, they will readily climb to reach food or escape predators when needed.
Keep reading to learn more about when, how, and why chipmunks take to the trees!

When Do Chipmunks Climb Trees?
Though they don’t live in trees, chipmunks are opportunistic foragers and will climb up trunks and branches in search of food. This behavior is most common in late fall when they are gathering nuts and seeds to store for winter.
Come November, it’s not unusual to see chipmunks scurrying up and down trees with their cheek pouches stuffed full of acorns, hickory nuts, and other protein-packed snacks. This pre-hibernation feast provides them with a nutritious cache to sustain them through winter.
Chipmunks may also take to the trees in summer when fruits like cherries and berries are ripe for the picking. Their sharp claws allow them to scale up and down with ease to harvest sweet treats.
Do Chipmunks Climb Trees to Escape Predators?
Interestingly, chipmunks usually won’t climb a tree to flee predators. They have an extensive burrow system underground with multiple escape routes. At the first sign of danger from a hawk overhead or a fox nearby, a chipmunk will typically dart back to the safety of its burrow.
However, if caught out in the open with no burrow access, a chipmunk may scurry up a tree for protection. They can climb surprisingly quickly to escape ground predators. And the cover of branches and leaves provides safety from aerial hunters.
Still, running to their burrow is always plan A. Chipmunks really only head for the trees as a last resort when they have no other options.
Do Chipmunks Nest or Sleep in Trees?
No, chipmunks don’t nest or sleep in trees. They are actually quite committed to their underground burrow systems, even in summer. It’s rare to find them spending the night above ground in a tree hollow or similar.
Their burrows provide the safest shelter and are highly complex, including separate chambers for nesting, food storage, and waste. While tree squirrels may sometimes crash in an abandoned woodpecker hole, chipmunks prefer the security of their burrows year-round.
Why are Chipmunks Not Better Tree Climbers?
Given that they are close rodent relatives of squirrels, it may seem odd that chipmunks aren’t more adapted to arboreal life. However, several key anatomical differences between chipmunks and squirrels explain why they tend to stay close to the ground.
- Chipmunks have relatively small claws compared to squirrels. Their claws aren’t as hooked or sharp, making it harder for them to grip bark and branches.
- Their hind legs lack the ankle flexibility and rotational ability that squirrels use to quickly scamper up and down trunks. Chipmunk ankle joints simply don’t allow the same range of motion.
- Chipmunks have a less bushy tail for balance and steering when moving through the canopy. Combined, these factors make climbing more challenging and less efficient for chipmunks than squirrels.
Signs of Chipmunks Climbing Trees in Your Yard
Wondering if the chipmunks in your backyard ever scurry up your trees? Here are a few clues to look out for:
- Look for small claw marks or scraping on tree bark – this can indicate chipmunks climbing up and down
- Keep an eye out for chewed nut shells or fruit pits at the base of trees – evidence that chipmunks are harvesting nuts and fruit from branches
- You may catch sight of a chipmunk’s striped tail disappearing into thick foliage as it climbs for cover
- Listen for the rustling of leaves and branches that can occur when chipmunks climb around
Do Some Chipmunks Climb More Than Others?
Just like people, some individual chipmunks do seem more adventurous and willing to climb than others. According to wildlife observations, male chipmunks appear to be the primary tree climbers.
Researchers believe more aggressive, dominant males may take to the trees to chase competitors away from prime nut and berry patches. Young chipmunks also climb more as they hone their foraging skills.
Additionally, chipmunks living in more urban areas with man-made bird feeders seem more inclined to climb to raid the feeders. So habitat and availability of easy food sources also play a role.
Why You Shouldn’t Encourage Chipmunks to Climb Trees
Seeing a chipmunk scurry up a tree can be an entertaining sight. But there are good reasons not to intentionally try to bring chipmunks into your trees:
- Falling danger – Unlike squirrels, chipmunks aren’t specialized tree climbers and can easily lose their grip or footing and get injured in a fall.
- Tree damage – Their small claw marks scar bark and their feeding can stunt new growth and damage fruit trees.
- Attracts predators – Hawks, owls, coyotes, and other predators follow chipmunks, which could reduce songbird numbers in your yard.
- Non-native nuisance – Chipmunks are not native everywhere, and introducing them where they don’t naturally occur can damage new ecosystems.
It’s generally best not to actively feed or encourage chipmunks around your property. Trim any nearby trees to remove easy climbing access. And keep pet food and bird feeders well away from the house.
Natural Pest Control for Nuisance Chipmunks
If chipmunks are already creating problems around your home, there are humane ways to deter them:
- Remove hiding spots like rock piles, dense brush, and mulch near foundations
- Plant native species like lavender, thyme, or garlic around gardens since chipmunks dislike the smell
- Use deterrents like crushed red pepper or predator urine near burrow openings
- Install mesh fencing around vegetable gardens and flower beds
Trapping and relocating nuisance chipmunks elsewhere is also an option (but check you local laws and regulations first). Just be sure to release them within 100 yards of capture. Bringing them further can spread diseases and upset local chipmunk populations.
So, do chipmunks climb trees? The answer is an emphatic yes – when they have to. Chipmunks have the ability to scurry up trunks and branches, but they typically stick close to the ground. Their burrows and underground tunnels are central to their survival and security.
These small striped rodents only really take to the trees when searching for food or escaping immediate danger. Even then, they usually don’t climb very high or very often. Still, keeping an eye out might allow you to spot one of these secretive burrowers showing off its surprising tree climbing skills!
