Recognition:
The only squirrel currently found in Cornwall,
the grey squirrel is one of our most frequently seen mammals. It is regarded as a pest by many because of the damage done to trees and gardens and their predation of birds and eggs. The grey squirrel reaches a
maximum body size of about 280 mm, with a tail of another 215 mm, and weighing up to 720 g. The winter coat is a speckled grey above with white underparts, in the summer
the shorter coat is more brown, with reddish
patches along the flanks and paws. Black
(melanic) and albino individuals are not unusual. They are very vocal animals and can often be heard barking and churring in response to threats from other squirrels and predators. The red squirrel in contrast is a much smaller animal with uniform colouring (although this may vary from bright chestnut to grey-red) and with no white margin to its tail. The red squirrel also has prominent ear tufts from late summer to early winter. Attempts are currently underway to
reintroduce the red squirrel to Cornwall in a few discrete areas. Occasional records of red squirrels in recent years are probably misidentifications.

Hind paw prints are about 45 mm long with the three long and narrow central toes
approximately equal in length. The front
paw is about 35 mm long and has 4 toes.
Droppings are similar in size and shape to rabbit droppings and are often left on
prominent branches, bird tables or the tops of tree stumps. Squirrels frequently strip
bark from trees, especially sycamore and beech, which often leaves scarring.

Grey squirrels occur in open woodland and parkland, preferring woodland with a good
proportion (over 25%) of mature trees, especially oak. In Cornwall they are commonly
found in broad-leaved woodland, often in association with oak and hazel. They are
common in urban gardens where they take advantage of bird feeders and domestic
scraps. They eat primarily buds, flowers, fruits and nuts, but will also eat fungi, insects, birds’ eggs and fledglings, as well as garden produce. Squirrels store or bury acorns and seeds below the soil surface: these stores are then recovered using scent, when food is scarce.
Grey squirrels produce one or two litters of three young each year in a football-sized
nest, or drey, built in close to the trunk of a mature tree. They also build communal
dreys in which small groups of individuals may sleep. Breeding females are strongly
territorial and will chase away other squirrels, often with a load chattering scream.
In captivity animals may live to 20 years but in the wild this is closer to 3 or 4. There are few natural predators in the UK, although foxes may have an impact in conifer plantations, and most deaths are probably related to starvation, accidents and human intervention. Many animals are killed by cars, and domestic cats may kill younger squirrels. Intensive attempts at controlling grey squirrels by shooting, trapping, or poisoning may have short-term effects locally.

Cornish Tales:
Grey squirrel apparently tastes like a cross between duck and lamb and has been a
popular item on the butcher’s counter at Kingsley Village in Fraddon.
