Typical squirrels include the European Red SquirrelThe Red Squirrel Sciurus vulgaris is a common European tree squirrel. It is still frequently found on the European continent and across Asia but has been widely replaced by the Eastern Grey Squirrel in Great Britain. They are small tree-dwelling omnivorou Sciurus vulgaris, the Fox Squirrel S. niger, the Eastern Gray Squirrel S. carolinensis, the Western Gray SquirrelThe Western Gray Squirrel Sciurus griseus is a tree squirrel found along the western coast of the United States. At various times and places, this species has also been known as the silver-gray squirrel, the California gray squirrel, the Oregon gray squir S. griseus, and the American Red Squirrel Tamiasciurus hudsonicus.
One well-known trait of some species of squirrel is the gathering and storing of nutsA nut in botany is a one-seeded (rarely two) simple dry fruit in which the ovary wall or part of it becomes very hard (stony or woody) at maturity. Most nuts come from pistils with inferior ovaries (see flower) and all are indehiscent (do not open at matu for the winterThis article is about the winter season. For other uses of the term, see winter (disambiguation). Winter is one of the four seasons of temperate zones. Astronomically, it begins with the winter solstice (around December 21 in the Northern hemisphere and J. These squirrels are scatter-hoarders , i.e. they will gather nuts and store them in any accessible hiding place, usually by burying them. Recent research shows that they have excellent memories for the locations of these caches.Squirrels are generally clever and persistent animals; in residential neighborhoods they are notorious for eating out of bird feeders, digging in potted plants either to bury or recover food, and for setting up house in sheltered areas including attics. Many companies sell bird feeders which are supposedly "squirrel-proof"; most of them in fact are not.
Squirrels are sometimes also pests because they chew on various edible and inedible objects; the habit helps keep the squirrel's teeth sharp and also wears the teeth down (rodents' teeth grow continuously). Homeowners in areas with a heavy squirrel population must keep attics and basements carefully sealed to prevent property damage caused by nesting squirrels. Fake owls and scarecrows are generally ignored by the animals, and the best way to prevent chewing on an object is to coat it with something to make it undesirable: for instance a soft cloth or chilli pepper paste or powder.
Squirrels can be trained to be hand fed. Because they are able to cache surplus food, they will take as much food as you put out. If a person starts to feed one, that squirrel will come back day after day to get its food. Squirrels living in parks and campuses in cities have learned long ago that humans are typically a ready source of food. Feeding is not recommended, however, because squirrels may carry plague or other animal-borne diseases.
The Red Squirrel populations in Britain, Ireland and more recently, northern Italy, have declined and become regionally extinct in recent decades, primarily because of competition from Gray Squirrels (introduced from North America), but also habitat loss. Conservation efforts include preserving and planting the conifer forests that Red Squirrels prefer. The recent colonisation of mainland Europe from Italy by Gray Squirrels is expected to result ultimately in the extinction of the Red Squirrel over most of Europe.
