The squirrel can be named hereby to “living fossils”: genus Sciurus exists from Oligocene in practically modern station. The unique circumstance prevents to make it: a wide living area and the big variety of modern squirrel species. It is possible, that any representatives of family Sciuridae could survive during mass extinction and evolve to new species of Neocene epoch. The garden squirrel does not exceed the common red squirrel (Sciurus vulgaris) in size. It is coloured brightly: an orange head and a body, black ears and a longitudinal strip on a back, a white belly, a long black-and-white striped tail (it is similar to a tail of lemur (Lemur catta)). With the help of tail position the squirrel communicates and submits each other signals. A voice is chirring, at danger - sharp whistling (as at gophers). The garden squirrel is one of numerous species of the African Neocaenic squirrels. It lives by big colonies on trees with edible foliage and fruits, obviously preferring a sugar tree because of sweetish taste of its foliage and plentiful, though also seasonal fruiting. Squirrels live in colonies at top of a rendered habitable by them tree where they build a huge collective dray. The top part of such dray is masked by plenty of epiphytic plants, which squirrels drag from the near trees and stick in a roof of a dray. Plants quickly get accustomed, as their roots will penetrate into drays of squirrels and receive secretions of these rodents as a source of additional mineral feed. The colony consists of main pair, set of the subordinated pairs (without rigid hierarchy between them) and the numerous young bachelors who have arrived from other colonies. Own cubs (3 packs for one year, 7 - 9 cubs in a pack) grow quickly and shortly young males are expelled from a colony and lead lonely life some time. At this time the significant part of them perishes. Becoming enough adult, young animals join already existing colonies and form pairs inside them. Squirrels look after a rendered habitable tree: they gather vermin insects (which simultaneously are used as "meat" part of feeding) and settling epiphytic plants from branches, gnaw out dry branches and too long sprouts. The young tree at first time is only visited by animals from the near large colony, and when the tree grows up, the own constant colony of squirrels is formed on its top. Active squirrel protection of a tree from large herbivores is original: as soon as animals will feel presence of herbivores (usually on a smell and a stir of branches), the part of a colony runs to protection of a tree. Squirrels run on the branches nearest to "calm ruffler" and start to shout loudly. If it does not help, some of squirrels bite a herbivore in a muzzle and lips, and the most courageous ones jump on a head of an animal and bite its skin. When the stranger departs from a tree, squirrels quickly jump on a branch and come back in a colony.
