SQUIRREL (Fr. ecureuil) , properly the name of the well-known red, bushy-tailed See also:British arboreal mammal, Sciurus vulgaris, typifying the genus Sciurus and the See also:family Sciuridae, but in a wider sense embracing all the rodents included in this and a few nearly allied genera. For the characteristics of the family Sciuridae and the different squirrel-like genera by which it is represented, see See also:RODENTIA. What may be called typical, that is to say arboreal, squirrels are found throughout the greater See also:part of the tropical and See also:temper-See also:ate regions of both hemispheres, although they are absent both from See also:Madagascar and See also:Australasia. The See also:species are both largest and most numerous in the tropics, and reach their greatest development in the See also:Malay countries. Squirrels vary in See also:size from animals no larger than a See also:mouse, such as Nannosciurus soricinus of See also:Borneo, or N. minutus of See also:West See also:Africa, to others as large as a See also:cat, such as the See also:black and yellow Ratufa bicolor of See also:Burma and the Malay See also:area. The larger species, as might be expected from their heavier build, are somewhat less strictly arboreal in their habits than the smaller ones. The See also:common squirrel, whose habits are too well known to need See also:special description, ranges over the whole of See also:Europe and See also:Northern See also:Asia, from See also:Ireland to See also:Japan, and from See also:Lapland to See also:North See also:Italy; but specimens from different parts of this wide range differ so much in See also:colour as to constitute distinct races. Thus, while the squirrels of north and west Europe are of the See also:bright red colour of the British See also:animal, those of the mountainous regions of See also:southern Europe are of a deep blackish See also:grey; while those from See also:Siberia are a clear See also:pale grey colour, with scarcely a tinge of rufous. There is also a See also:great seasonal See also:change in See also:appearance and colour in this squirrel, owing to the ears losing their tufts of See also:hair and to the See also:bleaching of the tail. The pairing See also:time of the squirrel is from See also:February to See also:April; and after a See also:period of gestation of about See also:thirty days the See also:female brings forth from three to nine See also:young. In addition to all sorts of vegetables and fruits, the squirrel is exceedingly fond of animal See also:food, greedily devouring mice, small birds and eggs. The squirrels of the typical genus Sciurus are unknown in Africa See also:south of the See also:Sahara, but otherwise have a See also:distribution co-extensive with the See also:rest of the family.

Although the See also:

English squirrel is a beautiful little animal, it is surpassed by many of the tropical members of the See also:group, and especially by those of the Malay countries, where nearly all the species are brilliantly marked, and many are ornamented The Burmese Red-bellied Squirrel (Sciurus pygerylhrus). with variously coloured See also:longitudinal stripes along their bodies. Every one who has visited See also:India is See also:familiar with the See also:pretty little striped See also:palm-squirrel, which is to a considerable extent a partially domesticated animal, or, rather, an animal which has taken to See also:quarter itself in the immediate neighbourhood of human habitations. It has been generally supposed that there is only one palm-squirrel throughout India, but there are really two distinct types, each with See also:local modifications. The first or typical palm-squirrel, Funambulus palmarum, inhabits See also:Madras, has but three See also:light stripes on the back, and shows a rufous See also:band on the under-See also:side of the See also:base of the tail. In See also:Pennant's palm-squirrel, F. pennanti, on the other See also:hand, there is a pair of faint additional lateral See also:white stripes, making five in all, and the under-See also:surface of the tail is uniformly whitish See also:olive. As this species has been obtained in See also:Surat and the See also:Punjab, it is believed to be the northern type. One See also:Oriental species (Sciurus caniceps) presents almost the only known instance among mammals of the See also:assumption during the breeding See also:season of a distinctly ornamental coat, corresponding to the breeding plumage of birds. For the greater part of the See also:year the animal is of a See also:uniform grey colour, but about See also:December its back becomes a brilliant See also:orange-yellow, which lasts until about See also:March, when it is again replaced by grey. The squirrel shown in the See also:illustration is a native of Burma and See also:Tenasserim, and is closely allied to S. caniceps, but goes through no seasonal change of colour. Another Burmese squirrel, S. haringtoni, differs as regards colour in a remarkable manner from all other known members of the group. It is a See also:medium-sized species of a pale creamy See also:buff colour above, lighter beneath, and with a whitish tail, while it is further characterized by the See also:absence of the first upper premolar, which shows that it is not an See also:albino or pale variety.

Two examples were obtained by See also:

Captain H. H. See also:Harington, of one of the Punjabi regiments, on the Upper See also:Chindwin See also:river. It may be added that generic subdivisions of the squirrels are based mainly on the characters of the See also:skull and See also:teeth. That they are essential is evident from the circumstance that the See also:African spiny squirrels Xerus (see SPINY SQUIRREL) come between Sciurus and some of the other African genera. (R.
