Why do red squirrels move so quickly?

A tiny force of nature, these fascinating wild animals move even faster in spring

Nobody has ever described a red squirrel as laid back and casual. They seem to live with the accelerator nailed to the floor, zipping around trees and through branches with blinding speed as they race around our Muskoka cottages and homes.

Nor are they the fast but silent type. They may be among the smallest of our Muskoka wildlife, but they don’t seem to know that. Any black squirrel that is perceived as an intruder will be chased away in a flurry of chattering and squeaking, every sound accompanied by a stomping of tiny feet and a flick of the tail. The same goes for gray jays, small dogs, and even owls: anything that might pose a threat is chased away.

That’s just part of their nature, standard red squirrel behaviour. At this time of year, they ramp that up a few notches.

There are a couple of reasons for this.

One is that late winter is breeding season for red squirrels. When the females go into heat, males will chase each other relentlessly in hopes of winning her affections. Those affections are short-lived, though – females are usually only in heat for a day, and almost as soon as she has mated, she leaves her partner or chases him away from her territory, sending him out to live with the other wild animals.

A mere 31 to 36 days later, a litter of 3 to 6 kits will be born, just as nature intended.

Nature’s storehouse

The other reason red squirrels are especially feisty at this time of year is because they are defending their food stores, caches of food that they rely on to keep themselves alive through the cold of a Muskoka cottage winter and the early spring season before the new growth emerges.

While most squirrel species store food for the winter, red squirrels have particularly large pantries. A grey squirrel will bury acorns and other nuts throughout their territory, hiding one or two nuts in each place and somehow remembering where most of them are.

Red squirrels, though, believe in going big when it comes to food storage. They can have as much as 50 litres of food hidden in a single cache! And while an individual squirrel may have several such caches, losing even one of them to an intruder is potentially catastrophic.

Red squirrel food supplies

They build these massive stockpiles in late summer and fall.  Among the foods to be found in their stockpiles are:

  • Pine cones
  • Mushrooms
  • Cherry pits
  • Beech nuts
  • Maple keys
  • Other protein-rich foods

Their main food is conifer cones — pine, spruce, fir and hemlock. They bite through the stems of the green cones and drop them to the forest floor, then go around later and pick them up, carrying them to damp storage sites like hollow logs and tree cavities. The moisture keeps the cones from opening and losing their seeds.

When red squirrels harvest mushrooms, they lay them out on sunny branches to dry before adding them to the cache.

They need these massive food stores to sustain their high energy levels. In a single day, a red squirrel might eat the seeds from 100 spruce cones.

When spring comes, they switch their diets a bit. They eat plant buds as they emerge, as well as insects and even the occasional bird egg or nestling.

And there’s a theory that red squirrels even helped invent maple syrup. In early spring when their food supplies are running low, red squirrels will bite the bark of sugar maples so the sap runs out. But they don’t drink it right away. Instead, they let the sun evaporate some of the water from the sap and return later to drink up the more concentrated sugar. Indigenous people, seeing this, realized the sap of the maple tree was sweet, and began experimenting themselves.
