Grey squirrel5/26/2023 ![]() They also eat berries, fruit, tree-buds, bulbs and other seeds. UK Grey's favourite foods include hazelnuts, acorns, chestnuts, peanuts, horse chestnuts, sunflower-seeds or any other type of nut with a shell on. From the chaser's perspective this makes it impossible to predict which way the squirrel is going to run, resulting in lost ground at every direction change. During the pursuit the squirrel's tail will often randomly flick to suggest the squirrel has changed direction when it hasn't or it went the opposite way. At speed a cat or dog cannot turn so sharply without losing it's footing. These are to throw off larger predators, which have a larger turning circle than a squirrel. When chased by either a predator or rival squirrel, squirrels run in a combination of zig-zags and small circles. ![]() The tail also serves a third purpose as well as balance and communication. They also have a complex, tag-team defensive system involving distracting would-be predators with vigorous shaking of their tails. Whilst Grey squirrels fight among themselves over food sources, they have been known to mob potential predators such as domestic cats. Predators include humans, hawks, mustelids,domestic and feral cats, owls and dogs. During colder months they still seem to dissappear for a nap at some point during the day, just not necessarily midday. Grey squirrels are more active during the early and late hours of the day, and tend to avoid the heat in the middle of a summer day. In addition, the squirrel may inhabit a permanent tree den. Squirrels may also nest in the attic or exterior walls of a house. The drey consists mainly of dry leaves and twigs. Grey squirrels build a type of nest, known as a drey, in the forks of trees. It does this by turning its feet so that the claws of its hindpaws are backward pointing and can grip the tree bark. It is one of very few mammalian species that can descend a tree head-first. Smell is used once the squirrel is within a few centimeters of the cache. The squirrels have very accurate spatial memory for the locations of these caches, and use distant and nearby landmarks to retrieve them. It has been estimated that each squirrel makes several thousand caches each season. Others are more permanent and are not retrieved until months later. Some caches are quite temporary, especially those made near the site of a sudden abundance of food which can be retrieved within hours or days for re-burial in a more secure site. Like many members of the family Sciuridae, the Grey squirrel is a scatter-hoarder it hoards food in numerous small caches for later recovery. Such large squirrels (usually female) are rare but not unknown in major cities in the UK (London, York and Sheffield are known hotspots) and are more than capable of defending against the majority of domestic cats. Although regardless of colour some urban squirrels, presumably better fed and almost semi-domesticated due to a lack of predators can reach 1kg and a height of 34cm with a tail pushing 30cm. The head and body length is from 23 to 30 cm, the tail from 19 to 25 cm and the adult weight varies between 400 and 600 grams. There are also genetic variations within these, including individuals with black tails and black coloured squirrels with white tails. The melanistic form, which is almost entirely black, is predominant in certain populations and in certain geographic areas, such as in large parts of southeastern Canada and certain southern areas of the UK. Particularly its in urban situations where the risk of predation is reduced, both pure-white and black-coloured individuals are sometimes found. It has a white underside and a large bushy tail. This is probably due to 20 generations of natural selection due to better camouflage rather than interbreeding with red squirrels. In the UK some examples appear more red than grey, confusing some into believing they have seen a true red squirrel. ![]() The Grey Squirrel ( Sciurus carolinensis) that has been introduced to the north pole to the india Background and descriptionĪs the name suggests, the Grey squirrel has predominantly grey fur, but it can have a reddish colour.
