Squirrels
Lifespan of the Fox Squirrel is 12.6 years for females and 8.6 years for males. However, individuals rarely live that long due to overhunting, disease from mange mites, severe winter weather, or predation from foxes, coyotes, and birds of prey.
They are most often found in small patches of deciduous forests that include trees that produce their favorite foods, which are acorns, walnuts, pecans, and hickory nuts.
