Squirrels bury nuts in their nests to keep them safe from predators. They often use different materials like mud, leaves, and twigs to make the nest more comfortable for themselves and their babies.

Squirrels bury their nuts to protect them from predators. Some squirrels will do this before the winter, while others wait until springtime.

Many people think of the pests that assault our bird feeders in the spring and summer when they hear the word “squirrel.” Then, in the autumn, they go about gathering and burying nuts until, fortunately, they vanish over the winter. Have you ever thought about why squirrels hide nuts in the first place?

Squirrels bury nuts and seeds in order to build up a winter food supply. As a consequence of the stockpiling, food is accessible at times when it would otherwise be unavailable. Furthermore, squirrels conceal food from opportunistic competition by burying nuts and seeds.

With the flurry of activity that squirrels generate when accumulating, a few additional issues arise, such as which nuts and seeds they prefer. Is it true that all squirrels bury their nuts? How frequently do squirrels locate these nuts after they’ve been buried?

Squirrels With Their Nuts: Why Do They Store Them That Way?

Squirrels are mammals that may be found on every continent except Antarctica and Australia.

Over 200 species of squirrels belong to the Sciuridae family, and they are divided into three broad divisions. Ground squirrels, flying squirrels, and tree squirrels are the three types of squirrels.

Squirrels have adapted successfully to the habitats in which they live.

Some squirrels have large bushy tails to provide shade and stay warm, whilst others prefer an arboreal or montane habitat.

The Diets of Squirrels and the Role of Nuts

Squirrels are omnivores who consume nuts and seeds, as well as various plant parts, insects, and even little eggs, depending on where they live.

Most squirrel species in the northern hemisphere (and other colder places in general) gather food for the winter. Nuts and seeds from different plants are included in this diet.

This conduct is inextricably related to the seasons.

Many species (mammals, insects, and reptiles) undergo a protracted period of sleep known as hibernation in colder climates across the globe.

Some animals do not really hibernate, but rather engage in a sort of hibernation or at the very least reduce their activity levels throughout the winter months.

Many animals, including squirrels, gather non-perishable food in the months leading up to winter and store it so they will have something to eat during the cold months.

Squirrels do not hibernate, but they do bunker down in their nests for the winter freeze, restricting their movements and activity to the absolute minimum and frequent food caches.

They survive the cold by metabolizing fat stored in their stockpiles/larders and consuming it. These pantries usually have enough food to survive the entire winter season, if not longer.

Plants and insects do not sprout immediately when spring arrives, so squirrels will have a food supply to tide them over.

Some squirrels don’t conceal all of their food in one location, preferring to “scatter horde” it over their home range in smaller caches (an area of up to around seven acres).

Other squirrels, on the other hand, build a single stockpile (known as a midden) and guard it ferociously from rival squirrels and other opportunists.

Squirrels don’t only store nuts and seeds in their burrows. Insects, fruit, and even bones are buried by them.

Another motivation for concealing food is to prevent competition from other squirrels (both of the same species and of other species) as well as other animals.

Food is concealed from anybody who did not hide it, since squirrels remember where they buried their caches (and many species bury many dispersed stores).

Squirrels are known to bury a variety of nuts and seeds.

The nuts and seeds that are buried and eaten vary a lot on the location in question, however some of the most regularly buried and eaten species include:

  • Oaks
  • Walnuts
  • Beeches
  • Hazels
  • Chestnuts from horses
  • Alders
  • Aspens
  • Birchs
  • Cypress
  • Maples in the Field
  • Hawthorns
  • Hollys
  • Junipers
  • Poplars
  • Hemlocks from the West
  • Red Cedars of the West
  • Willows

What Kind of Squirrel Buries Nuts, and Why Don’t Other Squirrels?

Squirrels do not all bury nuts and seeds. Some species dwell in places with mild winters and little to no frost, and hence do not need to store food since it is easily accessible throughout the year.

Tree cavities, forks in branches or tree trunks, beneath a mound of leaves, fallen logs, and a hole in the ground are among the hiding locations used by squirrels who hoard.

Squirrels that hide food for use over the winter may be seen in the photos below.

North American Squirrels Who Bury Nuts

We’ve compiled a list of squirrels in North America that hide nuts for later use.

  • Tamiasciurus hudsonicus (American Red Squirrel) burys its nuts/seeds in solitary middens.
  • Tamiasciurus douglasii squirrels bury their nuts/seeds in solitary middens (larder-hoarding).
  • Eastern Grey Squirrels (Sciurus carolinensis) bury their nuts and seeds in a variety of locations.
  • Sciurus niger (Fox Squirrel) buries its nuts/seeds in a variety of locations.

Squirrels Who Do Not Bury Their Nuts

Despite the fact that their numbers are small, a few squirrel species do not store food for the winter, owing to abundant winter food.

  • Abert’s Squirrels (Sciurus aberti) eat a variety of plants, including Ponderosa Pines. During the summer, they consume pine cones and buds, while during the winter, they devour tree bark.
  • Geosciurus inauris (Cape Ground Squirrels) dwell in South Africa, where they may graze all year and do not need to store food in a burrow.
  • Northern Flying Squirrels (Glaucomys sabrinus) eat fungus and lichens as part of their diet. Because they are active all year, they do not have food on hand.

What Methods Do Squirrels Use to Locate the Food They Bury?

Scientists are learning more and more amazing things about how squirrels recover their concealed caches throughout and after the winter season.

In the case of strewn cache squirrels:

Originally, it was thought that squirrels used smell to find their hidden food; however, with snow on the ground, this seems to be impracticable (although scent does play a role).

Squirrels have a “mental map” of their region and caches, dubbed “spatial chunking,” according to new research. The usage of landmarks is often critical in this procedure.

Squirrels can recall where they hid their caches by utilizing this memory map. They can discover their food (most of the time) because to their keen sense of smell.

Squirrels bury similar nuts in a certain place, whereas other nuts are gathered in other areas, according to scientists. This is to aid them in remembering where the different caches are concealed.

Squirrels dig up and rebury caches as a way of remembering where they hid what and ensuring that the food is still safe.

Researchers have also discovered that some of the higher “value” nuts/seeds are hidden in more susceptible, exposed regions by squirrels (especially the Eastern grey and fox).

Because of the heightened danger of predation, this location was chosen to deter rivals from raiding their stockpiles.

In 2008, a research led by Wilkes University’s Michael A. Steele revealed that squirrels deceive competition by seeming to bury food in one location.

If theft is a serious issue, squirrels will become inventive with their hiding places to prevent would-be thieves as much as possible.

Squirrels choose to return to the most large, high-quality caches first because they recall which cache held what sort of food and the amount of each.

Squirrel Nut Burying Habits Have an Important Consequence

Although squirrels bury nuts and seeds for their own survival, there is a secondary advantage to the process, which is forestation.

Squirrels don’t always find and collect all of their hidden nuts. These seeds/nuts germinate when they are buried in the earth.

These seedlings will grow to become the next generation of trees. Grey squirrels, in particular, are thought to play an important role in seed dissemination.

Last Thoughts

Although not all squirrel species bury nuts, those that do do so store the food in a single midden larder or a series of small, dispersed caches. Squirrels that bury nuts are more likely to reside in colder climates with hard winters, and they do so to avoid frost and food shortages.

Squirrels bury their nuts to store them for the winter. They do this because they need to eat throughout the year, and storing food is a good way to ensure that they will have enough food when it gets cold outside. Reference: do squirrels bury their dead.

Frequently Asked Questions

How do squirrels decide where to bury their nuts?

A: Squirrels have a habit of storing their nuts in the eventual location that they will dig up and eat months later. They bury them underground to help hide it from predators.

Do squirrels really forget where they bury nuts?

A: I dont know, but it sounds like a good story.

Why do GREY squirrels bury nuts?

A: Some experts believe that the behaviour is due to a genetic quirk, with grey squirrels being more likely than their brown counterparts to bury nuts. Others think its because of food availability and not enough light in areas where they live.
