Characteristics:

Black bears have short, non-retractable claws that give them an excellent grip for climbing trees. They have large, rounded ears, and their eyesight and hearing are sharp. What's really interesting is their sense of smell, which is much better than a human's and helps them find food!

Latin Name:

Odocoileus virginianus

Locations Found:

Throughout North America, from southern Canada to South America, including almost every U.S. state

Characteristics:

White-tailed deer are famous for the white underside of their tails, which they flash when sensing danger. They have powerful hind legs that allow them to leap distances of up to 30 feet and run very fast. In the fall, male deer (bucks) grow antlers to impress females (does) and spar with rivals. Their coats change color with the seasons, turning from reddish-brown in the summer to greyish-brown in the winter to blend into their surroundings better.

Latin Name:

Vulpes vulpes

Locations Found:

Red foxes have a wide range, found across the entire Northern Hemisphere, from the Arctic Circle to North Africa, North America, and Eurasia.

Characteristics:

Red foxes are known for their vibrant red fur, which can range from a deep rusty red to a golden orange, and white fur on their chest and belly. They have pointed ears, elongated snouts, and long bushy tails with a distinctive white tip, which they use as a warm cover in cold weather. These foxes are incredibly adaptable, capable of surviving in a wide range of environments by changing their diet and behavior to suit the conditions. Their keen sense of hearing allows them to hear prey moving underground, and they use a unique hunting technique called ‘mousing,’ where they leap into the air and pounce to catch their prey.

Latin Name:

Sylvilagus floridanus

Locations Found:

Cottontail rabbits are found in North and Central America, inhabiting areas from southern Canada to northern South America.

Characteristics:

The cottontail rabbit's most notable feature is its white, puffy tail, which resembles a cotton ball and gives the animal its name. With big brown eyes and long ears that can measure up to 7 cm (about 2.75 in), they have excellent hearing to detect predators. Their strong hind legs are designed for quick escape with leaps up to 3 meters (10 feet) long. Their fur changes color seasonally, providing better camouflage against the snow in winter and matching the earthy tones of the ground during summer. These rabbits are crepuscular, meaning they are most active during dawn and dusk when the light is dim, allowing them to stay hidden from predators while foraging.
