Some species of squirrels may claim as much as 10 hectares of territory. Because of the high density of squirrels in most habitats, there is sometimes significant territory overlap. Squirrels mark their territory with urine and tail-waving displays, and they may bark warning calls at passing intruders, including humans.
The squirrel's total body length measures 45 to 70 cm (17.7 to 27.6 in), tail length is 20 to 33 cm (7.9 to 13.0 in), and they range in weight from 500 to 1,000 grams (1.1 to 2.2 lb). There is no sexual dimorphism in size or appearance. Individuals tend to be smaller in the west.
