squirrel

small, arboreal, mostly herbivorous rodents varying in color from gray to shiny black, red and cream, and in size from mouse to large cat. Some are insectivorous, and many are terrestrial, e.g. the chipmunks. Some glide although they are called flying squirrels. Most squirrels are diurnal but the flying genera are nocturnal. They are all members of the family Sciuridae, which includes a very large number of species, and are distinguished by their fine, dense fur and their bushy, plume-like tails and ears that are often surmounted by tufts of hair.
