Six things about the grey squirrel

Arrival

From America

Grey squirrels were brought from North America in the 1870s. There are now well over two million in Britain.

Reds

Trouble for the reds

They outcompete red squirrels for food and carry a virus that is deadly to reds but harmless to themselves.

Nuts

Fake burying

A squirrel that thinks it is being watched will pretend to bury a nut, then hide it somewhere else.

Ankles

Head first

Squirrels can turn their back feet right round, which lets them run down a tree trunk head first.

Ears

No ear tufts

Unlike the red squirrel, a grey squirrel never has tufts on its ears.

Trees

Accidental foresters

Many of the nuts they bury are never dug up again, and grow into trees.

How to spot one

Look in any park with big trees. Listen for a scolding, chattering call, and look for a ball of leaves and twigs high in a tree: the squirrel's nest, called a drey.

Lend a hand

How to help

In areas that still have red squirrels, such as Cumbria, Northumberland and Scotland, report any grey squirrel you see to the local red squirrel group.
