Chipmunk Cheeks: Everything You’ve Ever Wanted To Know
Chipmunks have unique cheeks that can grow up to the size of their body! Have you ever wondered how this happens or why chipmunks stuff their cheeks?
Chipmunk cheeks contain pouches, or pockets, designed to hold food. They can stretch up to three times the size of the chipmunk’s head and hold over 160 acorns! This allows chipmunks to prep for winter in just two days.
Learn more about cheek pouches and their uses in this article. We’ll tell you everything you’ve ever wanted to know!
Do Chipmunks Have Fat Cheeks?

Chipmunks have fat cheeks because they have cheek pouches. They use these cheek pouches to store food until they can deposit the food in their den. This allows them to gather mass amounts of food very quickly—which is very important to them. Chipmunks are food hoarders!
Cheek pouches vary in different animals, sometimes reaching the shoulders or sides of the neck. In chipmunks, the cheek pouches extend to the shoulders and stretch very wide. Another great thing about cheek pouches is that chipmunks can run away from predators if needed without leaving their food behind. Otherwise, they could only eat one item at a time and would have to abandon it if a predator came along.
Chipmunks also use their cheek pouches to contain dirt when digging their burrows. They later deposit the dirt on the ground outside. This is why chipmunk holes don’t have mounds of dirt surrounding them. Lastly, cheek pouches allow chipmunks to stock up for winter in just two days.
How Big Can Chipmunk Cheeks Get?
Chipmunk pouches can expand to make their head look three times larger than usual!
Chipmunk cheeks can grow up to three times the size of their heads! They can hold onto mass quantities of food as big as themselves. Things a chipmunk might store in their pouches include seeds, nuts, grain, fruit, insects, fungi, bird eggs, and even baby birds or mice.
Why Do Chipmunks Fill Their Cheeks?
Chipmunks fill their cheeks in order to hoard food quickly. They don’t tend to eat while out and about but instead tuck the food away for eating in the safety of their dens. The outside world is dangerous to these tiny animals, with predators everywhere. The quicker they can scurry around collecting their meal, the safer they’ll be.
Another thing chipmunks do to avoid harm is to rely on others. When they see a predator, they make a sound that tells other chipmunks whether it’s on the ground or in the air. When chased by a predator, chipmunks make yet another noise to warn the surrounding colony.
The other purpose for chipmunk cheeks is to dig burrows. They dig far underground with their claws, stuffing dirt into their cheek pouches as they go. When they’re finished, they go back outside and leave the dirt on the surface. This makes them neater diggers than most other animals that simply leave the dirt where it falls.
How Do Chipmunks Empty Their Pouches?
Chipmunks empty their cheek pouches into their burrows. colacat/Shutterstock.com
Chipmunks squeeze their cheek pouches with their front paws to empty them. This efficiently empties the food into their dens and takes very little time. We don’t often get to see chipmunks empty their cheek pouches since it happens below ground. Rest assured, it’s incredibly cute!
Where Do Chipmunks Store Food?
Most chipmunk species store food in their dens. Chipmunk burrows consist of an underground nest, where they sleep, surrounded by runs that lead to other crevices. One is used for going potty, another for giving birth, and the rest for hoarding food!
Chipmunks often gather much more food than they need to survive and hide it away in their burrows. Just one chipmunk lives in each burrow because they aren’t social animals.
Do Chipmunks Hibernate?
Chipmunks don’t hibernate. Instead, they go into a similar state called torpor. They go into a hibernation-like sleep for a few days at a time, during which their systems slow dramatically. Their hearts beat just four times a minute, and their body temperatures drop to around 40 degrees Fahrenheit.
Every few days, though, they wake to use the bathroom and eat. Their body temperature also raises at this time. Most of their activity happens inside their burrow since they have their kitchen and bathroom all built-in! You might see a chipmunk scurrying outside on warm winter days, but it’s pretty uncommon.
Chipmunk Facts
Chipmunks are rodents that are a type of squirrel. These small, furry animals are identified by their stubby legs, bushy tails and the white, black and brown stripes that run down their backs.
Size
Chipmunks are the smallest members of the squirrel family, according to National Geographic (opens in new tab). The biggest species of chipmunk is the Eastern chipmunk. It grows to 11 inches (28 centimeters) and weighs up to 4.4 ounces (125 grams).
Chipmunks typically grow to around 4 to 7 inches (10 to 18 cm) and weigh 1 to 5 ounces (28 to 142 g). Their tails can grow as long as 3 to 5 inches (8 to 13 cm).
Habitat
There are 25 species of chipmunk, according to National Geographic. Only one of those species, called the Siberian chipmunk, lives outside of North America. The Siberian chipmunk lives in Asia and is expanding into parts of Europe, according to the International Union for Conservation of Nature (IUCN). In North America, chipmunks can be found almost anywhere there are trees.
Chipmunks make homes for themselves by creating burrows that consist of an underground tunnel system or by making nests in logs or bushes. Their tunnel systems can be 10 to 30 feet (3 to 9.1 m) long.
Habits
Though you may see chipmunks around each other, they are not social animals. They like to keep to themselves and only interact during mating season, which is in the spring.
They are most active at dusk and dawn. Chipmunks spend most of their days foraging. A single chipmunk can gather up to 165 acorns in a day, according to National Geographic Kids (opens in new tab).
Chipmunks hibernate, but they don’t store fat to see them through long winters like bears do. During the warm months, chipmunks will stuff extra food into their cheek pouches. These cheeks are massive grocery bags. They can stretch to be three times larger than the chipmunk’s head, according to Connecticut’s Department of Energy and Environmental Protection. When they have a full load, they carry the food to their home and store it. During the winter, they eat from their food cache for energy.
During hibernation, chipmunks can seem like they are dead. Their heart rates can drop from 350 beats per minute to around 4 beats per minute, and their body temperature can drop from 94 degrees Fahrenheit (34.4 Celsius) to as cold as 40 F (4.44 C), according to the National Wildlife Federation (NWF).
Diet
Chipmunks are omnivores, and they aren’t picky about what they eat. Part of their diet consists of vegetation such as mushrooms, berries, nuts, seeds and grains. Chipmunks also eat other creatures such as insects, baby birds, frogs and bird eggs, according to the Wildlife Hotline.
Offspring
Like other rodents, chipmunks have live births after carrying their young for a gestation period of around 30 days, according to National Geographic. Female chipmunks usually give birth to two to eight young at one time and give birth one to two times per year, once in the late spring and sometimes again in the fall. Their young are called pups. A group of pups that are born to the same mother, at the same time, is called a litter.
Pups are hairless, blind, pink creatures the size of a jelly bean. Mothers are very protective of their young and if one goes missing, she will search frantically for it, according to the Wildlife Hotline.
The protection doesn’t last for long, though. Pups only stay with their parents for around two months. Then, they build their own home and start gathering food to last them throughout the coming winter.
Classification
According to the Integrated Taxonomic Information System (ITIS), the taxonomy of the chipmunk is:
Kingdom: Animalia
Subkingdom: Bilateria
Infrakingdom: Deuterostomia
Phylum: Chordata
Subphylum: Vertebrata
Infraphylum: Gnathostomata
Superclass: Tetrapoda
Class: Mammalia
Subclass: Theria
Infraclass: Eutheria
Order: Rodentia
Suborder: Sciuromorpha
Family: Sciuridae
Subfamily: Xerinae
Tribe: Marmotini
Genus: Tamias
Subgenera: Tamias (Eastern chipmunk); Eutamias (Siberian chipmunk, with nine subspecies); Neotamias, (Western chipmunks, with 23 subspecies). Some studies have suggested that these should be separate genera.
Conservation status
According to the IUCN’s Red List, only one chipmunk species is endangered. The Palmer’s chipmunk, Tamias (Neotamias) palmeri, is found only on one small mountain range, the Spring Mountains in southwestern Nevada. Their population decline is due mostly to the invasion of humans in their habitat and domestic cats killing chipmunks in large numbers.
The Buller’s chipmunk, Tamias (Neotamias) bulleri, is the only species listed as vulnerable. This classification is due to population decline and distribution fragmenting. The Buller’s chipmunk is only found in Sierra Madre in south Durango, west Zacatecas and north Jalisco, Mexico.
Other facts
Chipmunks make various sounds to communicate. There are three recognized chipmunk calls, according to the NWF. The three calls are called the chip, the deeper chuck and the startle call. The BBC has a recording of a chipmunk’s sound.
According to New Hampshire Public Television, the name “chipmunk” comes from the “chip-chip” sound the creature makes.
Chipmunks require colder temperatures to hibernate. As the temperatures warm due to global warming, they may no longer hibernate.

Cheek pouch
Cheek pouches are pockets on both sides of the head of some mammals between the jaw and the cheek. They can be found on mammals including the platypus, some rodents, and most monkeys,[1][2] as well as the marsupial koala.[3] The cheek pouches of chipmunks can reach the size of their body when full.
Description and function [ edit ]
Cheek pouches are located in the thickness of the flange on both sides of the head of some mammals. Monkeys have open cheek pouches within the oral cavity, but they open out in some rodents of America. Hence the name “diplostomes” is associated with them, which means “two mouths.” In some rodents, such as hamsters, the cheek pouches are remarkably developed; they form two bags ranging from the mouth to the front of the shoulders.[4] Étienne Geoffroy Saint-Hilaire described that some bats of the genus Nycteris have an amazing form of cheek pouches, as they have a narrow opening, through which the bat can introduce air, closing the nasal canal through a special mechanism and pushing air under the skin, so they expire in the tissue, which unites the very loose skin to the underlying muscles.[4]
Cheek pouches have several roles; they allow the rapid collection of food, but also serve as temporary storage and transport. In monkeys of the subfamily of Cercopithecinae, they allow for more predigested food.[5] Cheek pouches contribute to the protection of animals by allowing them to carry their food in the pouches to shelter, allowing them to transport their food to safer locations, as they are pressing these pouches to the back of the mouth with the back of the leg, or moving the jaw.[5][6] The females of some species of hamster are known to hide their young in their cheek pouches to carry them away when they fear danger.[7] Other species of hamsters are known to fill their pouches with air, allowing them to float better while they swim.[7][8]
The cheek pouches can become infected as a result of an injury caused by a sharp object inserted into them or a fight. An abscess can form, which can be confused with protuberance with stored food. If the abscess bursts and the pus contained therein is absorbed by the animal, it can develop sepsis and die of the poisonous toxins.[9][10][11][12] The cheek pouches can also turn outwards.[9][13]
The cheek pouches of hamsters have been studied in laboratories to understand vascular membranes and healing better.[14] They are also useful for the study of the immune system, notably in the development of abscesses or tumours.[15][16][17]
Examples [ edit ]
Chipmunks [ edit ]
Chipmunks (Tamias) have large cheek pouches that allow them to transport food.[18] These pouches can reach the size of their body when they are full.[7][18][19]
Below is the introduction of the legume (pod) of peanut in the cheek pouch of a chipmunk:
Peanut half entered the cheek pouch
Peanut during storage
Peanut entirely in the cheek pouch

Hamsters [ edit ]
One of the classic behavioral characteristics of hamsters (subfamily Cricetinae) is food hoarding. Hamsters carry food to their underground storage chambers using their spacious cheek pouches.[20] A hamster “can literally fill its face with food.”[21] When full, the pouches can make the hamsters’ heads double, or even triple in size.[20]
Platypus [ edit ]
The platypus feeds on annelid worms, insect larvae, freshwater shrimps, and yabbies (freshwater crayfish) that it digs out of the riverbed with its snout or catches while swimming. It uses its cheek pouches to carry prey to the surface for eating.[22]
Misconception with Rattus rattus [ edit ]
The cheek pouch is a specific morphological feature that is evident in particular subgroups of rodents (e.g. Heteromyidae and Geomyidae, or gopher), yet a common misconception is that certain families, such as Muridae (including the common black and brown rats), contain this structure when in fact their cheeks are merely elastic due to a high degree of musculature and innervation in the region. The true cheek pouch, however, is evident in the former Heteromyidae and Geomyidae groups.[23]

Cheek pouches are more pronounced in certain rodents, such as hamsters, yet this structure is also distinguishable on certain species of rat, like the Gambian pouched rat, of which extensive morphological investigations have been conducted.[23] Aspects including rat pouch musculature, vascularization, and innervation were all explored and compiled through this and other studies. The widely distributed Rattus rattus is an example of the rodent family Muridae that lacks a true cheek pouch; rather, they exhibit more elastic cheeks (not true pouches) due to the organization of their cheek musculature.
Concerning the musculature, the cheek pouch is composed primarily of a developed masseter (cheek) muscle that exhibits a high tensile ability. The masseter muscle has been shown to insert into the pectoralis muscles, allowing for a higher degree of food retention. The pouch is clearly divided between a buccal (cheek) and sublingual (below the tongue) portion. Volumetric analyses within this study attributed the differences in net cheek volume between male and female rats to the average size of the respective sexes.[24]
Due to muscle’s high nutritional demand, this muscle exhibits vascularization that has been highly studied. Dissections at Boston University by Frank Brodie describe the various bifurcations (or splittings) of the common carotid. This artery splits into an internal and external branch, of which the latter extends dorsally and divides into five branches that supply the general cheek region. The branch that extends dorsally to the ear is known as the auricular branch.[25]
As for innervation of this structure, the associated nerve branches were all found to originate from the facial (CN VII of XII) nerve that initiates at the medulla and passes into the facial canal via the stylomastoid foramen. The primary aforementioned muscle, the masseter, is supplied by two large neural branches known as the temporalis and zygomatic nerves.[25] The buccal divisions of this nerve supply much of the masseter muscle, which ultimately facilitates the voluntary retention of food within the cheek pouch.
