Squirrels are generally small in statue, ranging in size from 2-4 in. in length, to 21-29 in long. They have a slender body with bushy tails and large eyes. In general, the hind limbs are longer than the fore limbs, and they have 4 or 5 toes on each paw. Unlike most mammals, Tree squirrels can descend a tree head-first. This is done by rotating their ankles 180 degrees so the hind paws are backward-pointing and can grip the tree bark.
Squirrels breed once or twice a year and give birth to a varying number of young after three to six weeks. Ground and tree squirrels typically move around during the day, while flying squirrels are nocturnal.
Squirrels cannot digest cellulose, so they must rely on foods rich in protein, carbohydrates, and fats. They feed primarily on nuts, seeds, conifer cones, fruits, fungi, and green vegetation.
For homeowners, squirrels can be extremely troublesome. They will naw on sides of homes, tear through mesh, chew on wires, and set up nest inside attics.
A proper inspection around your home is encouraged and the exclusion of any holes or gaps is highly recommend.
