Red squirrels are smaller and found in coniferous forests, known for vocalizations and food caching. Fox squirrels are larger and skilled climbers. Flying squirrels can glide through the air due to a specialized membrane. Squirrels generally do not harm humans but can become a nuisance. They have an omnivorous diet and can be attracted to backyards with feeders. Squirrels are generally solitary but exhibit some social behaviors. They play a crucial role in seed dispersal and forest regeneration.
The Different Types of Squirrels in North America
Introduction
Squirrels are small mammals that belong to the family Sciuridae. They are known for their bushy tails, sharp claws, and nimble movements. North America is home to several species of squirrels, each with its own unique characteristics and habitat preferences.
Gray Squirrels
Gray squirrels are one of the most common and widely recognized squirrel species in North America. They have a grayish-brown fur coat and a long, fluffy tail. These squirrels are highly adaptable and can be found in a variety of habitats, including forests, urban areas, and suburban neighborhoods. Gray squirrels are known for their agility and ability to quickly climb trees.
Red Squirrels
Red squirrels, also known as pine squirrels, are smaller compared to gray squirrels and have a reddish-brown fur coat. They are commonly found in coniferous forests across North America. Red squirrels are known for their vocalizations, including high-pitched chattering sounds, and their preference for caching food in various locations.
Fox Squirrels
Fox squirrels are larger in size compared to both gray and red squirrels. They have a predominantly rusty-red fur coat and can be either gray or black as well. Fox squirrels are commonly found in hardwood forests and are known for their excellent climbing skills and ability to jump long distances.
Flying Squirrels
Flying squirrels, despite their name, do not actually fly but glide through the air. They have a specialized membrane called a patagium that stretches from their wrist to their ankle, allowing them to glide effortlessly among the trees. There are three species of flying squirrels in North America: northern flying squirrel, southern flying squirrel, and Humboldt’s flying squirrel.
