The acrobatic antics of squirrels provide hours of entertainment as they leap from tree to tree chirping and scurrying along high branches. Each squirrel claims a territory ranging from 1 to 7 acres where he will hide food and raise young. Squirrels mark their territory in a variety of ways including stripping bark, rubbing their scent glands on food or trees and spraying urine.
Spraying is done exclusively by the male squirrel, usually accompanied by stripping a small area of bark from the tree. Scent markings appear most frequently on black walnut and sycamore trees and less frequently on pines and oak, according to a 1991 study by the University of Kansas. Female squirrels use scent glands on their feet and face to show their presence in their home territory.
