Identification

• The name squirrel comes from the Greek translation for "shadow-tailed." This fits well because squirrels can often be identified by bushy tails, which they use as shelter from nature's elements. Squirrels in North America live in trees, while those in Europe and Asia oftentimes nest on the ground level.
  
  

Features

• The squirrel belongs to the Sciuridae family and is related to chipmunks, flying squirrels, woodchucks and prairie dogs. They need foods with high levels of protein, fat and carbohydrates. Thus, squirrels tend to eat nuts, seeds, insects, conifer cones, fruits, fungi and some green vegetation. Some squirrels in Asia and Europe also have been known to eat chickens, snakes, lizards and smaller rodents.
  
  

Type

• Fox squirrels, which live in eastern and southern parts of North America, are known for their distinct coloration of brown fur and yellow under-bellies. Gray squirrels, which are can be found in both North America and parts of Europe, have gray fur and white bellies with grayish black tails. The red squirrel has rust colored fur and a white belly, while the black squirrel has dark fur and a dark brown tail. Both red and black squirrels are found mostly in the United States, but variations can be found in Europe and Asia.
  
  

The Facts

• Squirrels are most active during mating season, which occurs during the late winter months. The average gestation period for a squirrel is around 40 days, with four being the average litter size. Once a squirrel has reached adulthood, they tend to live alone and only correspond with other squirrels for mating purposes.
  
  

Risk Factors

• Squirrels are known for their shrewd and persistent character. They can be bothersome to homeowners and gardeners. They tend to dig into flowerbeds and set up nests in basements or attics. Squirrels have sharp teeth, so they can do damage to household objects and power lines. To solve a squirrel infestation, a rodent exterminator should be contacted.
