Beaver vs. Red Squirrel
What's the Difference?
Beavers and red squirrels are both small mammals that can be found in North America. However, they have very different lifestyles and behaviors. Beavers are known for their large, flat tails and their ability to build dams and lodges in bodies of water. They are primarily herbivores and spend much of their time in the water. Red squirrels, on the other hand, are agile climbers that spend most of their time in trees. They are known for their reddish fur and bushy tails. Red squirrels are omnivores and feed on a variety of nuts, seeds, and insects. Overall, while both animals are fascinating in their own right, they have very different adaptations and behaviors that allow them to thrive in their respective habitats.

Further Detail
Physical Attributes
Beavers are large rodents known for their stout bodies, webbed feet, and flat tails. They can grow up to 3 feet long and weigh as much as 70 pounds. Their fur is typically brown, with a waterproof layer that helps them stay warm in the water. Red squirrels, on the other hand, are much smaller in size, measuring only about 7-8 inches long and weighing around 6 ounces. They have a reddish-brown fur coat with a white belly and bushy tail.
Habitat
Beavers are primarily aquatic animals that build dams and lodges in freshwater habitats such as rivers, streams, and ponds. They use their sharp teeth to fell trees and construct their elaborate structures. Red squirrels, on the other hand, are arboreal creatures that live in forests and woodlands. They build nests called dreys in trees and are known for their agility in climbing and jumping from branch to branch.
Diet
Beavers are herbivores that primarily feed on tree bark, leaves, and aquatic plants. They are known for their ability to alter their environment by creating dams that flood areas and create new habitats for themselves. Red squirrels, on the other hand, have a more varied diet that includes nuts, seeds, fruits, and insects. They are known for their habit of storing food in caches for the winter months.
Behavior
Beavers are social animals that live in family groups consisting of a monogamous pair and their offspring. They are known for their engineering skills and the complex systems of dams and lodges they build. Beavers are primarily active at night and are excellent swimmers. Red squirrels, on the other hand, are solitary creatures that are territorial and will defend their home range from other squirrels. They are diurnal animals that are most active during the day.
Reproduction
Beavers typically mate for life and produce one litter of kits each year. The female beaver gives birth to 1-6 kits, which are born fully furred and with their eyes open. The kits stay with their parents for about two years before they disperse to find their own territories. Red squirrels, on the other hand, have a shorter gestation period and can produce 2-4 kits in a litter. The young squirrels are born blind and hairless and are cared for by their mother until they are old enough to fend for themselves.
Conservation Status
Beavers were once heavily hunted for their fur and castoreum, a substance used in perfumes and medicine. As a result, they were nearly driven to extinction in many parts of their range. However, conservation efforts have helped to restore beaver populations in some areas. Red squirrels, on the other hand, are facing threats from habitat loss and competition with invasive species such as the gray squirrel. Conservation efforts are underway to protect red squirrel populations and their forest habitats.
