Southern Flying Squirrel - Glaucomys volans

Southern flying squirrels have gray brown fur on the back and a white belly. The tail is also gray and flattened. They have large eyes due to nocturnal habits.

They eat fruit, nuts, flowers, insects, mushrooms, carrion, and bird eggs.

 Family Castoridae

American Beaver - Castor canadensis

American beavers have a large, flat tail which they use to slap the surface of the water to signal danger. They have webbed hind feet and smaller front paws with claws that are not webbed. The eyes have a membrane that allows the beaver to see underwater. A thick layer of fat insulates the beaver from cold water temperatures. The dark brown fur is a double coat that has coarse outer hairs and fine inner hairs. Adults weigh on average 44 lb. but range from 24-71lb. Body length is 29-35 in, with an additional 8-14 in. with the tail.

They hunt small mammals including raccoons, rabbits, and rodents. They communicate through vocalizations including howls, barks, growls, and yaps. The howl sounds similar to a coyote's, but has a lower pitch that lasts longer. Due to predator control programs and loss of habitat, red wolves were on the brink of extinction. A successful effort has been made to capture, breed, and release some back into the wild. Interactions with coyotes have also put them at risk of hybridization, minimizing their chance to remain as a unique species.

Red Fox -Vulpes fulva
