Fun Grey Squirrel Facts For Kids

The eastern grey squirrel or grey squirrel, Sciurus carolinensis, is an arboreal rodent. It is a species that is native to North America and is an important component of the forest ecology.

Grey squirrels were located and introduced to Europe and are considered an invasive animal species in some regions. Grey squirrels are recognized by their grey fur but can also have brown fur.

It has a white underside and a bushy tail. In certain urban locations, a complete black species can be found too. Grey squirrels melanistic species can tolerate colder climates than the regular grey ones.

The eastern grey squirrel is known as a scatter-hoarder. Meaning it will hoard food at numerous locations in small caches to recover later.

They are estimated to make several thousand caches individually in every season. Some are temporary caches from where it will collect the food to transfer to a more permanent cache place.

From the permanent spot, the food is not retrieved until required. The invasive grey squirrel or eastern grey squirrel has excellent spatial memory to track the location of each cache while using distant and nearby landmarks to do so. Grey squirrels use their sense of smell to receive the food cache.

Eastern grey squirrel adaptations can descend from a tree headfirst. After reading these interesting grey squirrel facts, do check our other articles on weasel facts and roof rat facts as well.

Once ejaculation is done, a gelatinous white plug is formed, which doesn't let more sperm enter. These periods are during December to February and May to June. The gestation period is 44 days.

Newborns are naked at birth and are altricial. They are born pink with no hair. Although vibrissae are present, after seven to eight days, the skin will darken.

The conservation status of the grey squirrel is of Least Concern as the population is stable and increasing. In certain areas where the species was introduced, the population is said to be invasive.

Although habitat loss and human encroachment may be a cause for concern for them, the species has adapted well to co-exist with humans in urban and rural areas.
