Black Bear

Black bears are omnivores, meaning they eat various foods, including fruits, grasses, meat, berries, nuts, carrion, and insects. They also tend to utilize crops if they are available. Since human settlements are located close to many parts of their range, and their habitat is being used more and more for recreational purposes, the American black bear has adapted to include a variety of human-related foods in their diet, such as refuse, birdseed, agricultural products, and honey from apiaries.

At the Zoo, black bears receive a specialized ground carnivore diet, a prepared omnivore chow, and produce. One of the favorite forms of food enrichment are mealworms.

Bears can be found all over North America, from the northern regions of Mexico to the Yukon and Northwest Territory in Canada. They have a wide range of movement and travel long distances to find food. In fact, it has been documented that they can travel up to 125 miles from their denning site!

Black bears primarily inhabit a wide range of forest environments. They possess the ability to adapt their diet to surrounding circumstances, which allows them to live in a diverse range of habitats.

Black bear cubs can be in danger from larger predators like wolves and mountain lions. Adult black bears have few predators.

Throughout history, the American black bear has faced threats such as hunting, human disturbance, and losing its home due to development. The biggest threat today is human-bear conflict, as urban development and roads continue to take over its habitat. This puts them closer to human settlements and food sources like garbage, bird feeders, and crops, which can be dangerous for large predators.

The term "black bear" can be misleading because this species has a wider range of fur colors than any other mammal in North America.Most black bears in the eastern United States have black fur, but in the western regions, many bears may have lighter colors like cinnamon or yellow-brown. Some bears along the Pacific coast have gray-blue fur, and in British Columbia, Canada, about 10% of them have completely white fur! The different fur colors may be influenced by their habitat and weather, and even bears born in the same litter can have different colors.

Black bears have a solid body shape, with a rear end that is higher than their shoulders. They have strong, short legs and curved claws that are perfect for climbing trees and digging. Their snouts are long and straight. One amazing fact about them is that their sense of smell is thought to be seven times better than that of a bloodhound.

Black bears usually breed in mid-summer. They have a special reproductive process called "delayed implantation." This means that after the eggs are fertilized, they don’t attach to the mother’s womb right away; instead, they wait until November. This helps the mother bear eat enough food before winter, giving her and her cubs a better chance to survive.

After about 10 weeks, she gives birth to a litter of about two to three cubs. The family leaves their den when the cubs are around three months old. For the first year and a half, the cubs stay with their mother, who takes care of them all by herself. The cubs grow quickly in their first year. When they are born, they are tiny and weigh about eight ounces, and they can’t see. By the time they are six weeks old, they weigh between three and four pounds. By September, they usually weigh between 25 and 65 pounds, and when they go back into the den with their mother in early November, they might weigh as much as 70 to 80 pounds.

Black bears communicate in several ways, including sounds, body language, and scent-marking. Their calls can be deep, clear, and quite loud. They use different sounds depending on the situation, like grunts, huffs, screams, and even clicks of their tongue and jaw. Some of their sounds can resemble a human voice, especially when they are stressed. When black bears feel nervous or threatened, they may act aggressively. This can include pouncing towards the perceived threat, slapping the ground or nearby objects, and making loud blowing sounds. They might also perform a bluff charge to scare off whatever is making them feel threatened.

Black bears are usually active in the early morning and late evening, which is known as being crepuscular. Their activity can change based on how much people are around. For example, bears that live in busy areas may be more active at night, while those in quieter places are mostly awake during dawn and dusk.

When it gets colder and food is hard to find, black bears enter a light sleep called "torpor." They don't truly hibernate, but during this time, their heart rate, breathing, and metabolism slow down a lot. This helps them save energy and get through tough winter conditions.
