American Black Bear: where and when to see them

The American black bear is a widespread North American omnivore, occupying forests from Alaska to the southeastern United States. Despite its name, its coat may be black, brown, cinnamon or, in certain coastal populations, much paler. It is usually smaller and less heavily shouldered than a brown bear. Regional diets and seasonal movements vary greatly, so an Alaskan shoreline bear and a New England woodland bear may be exploiting very different resources.

Black bears are mostly solitary except for mothers with cubs and temporary gatherings at abundant foods. They climb readily, investigate their surroundings with an excellent sense of smell and can become strongly attracted to unsecured human food. Feeding intensifies before winter denning, when suitable fat reserves are crucial. Denning duration varies with climate and food supply. Females give birth while denned, and cubs remain dependent on their mother well beyond their first summer. They possess an acute sense of hearing and a relatively good sense of sight, though smell is their primary sense for locating food. Black bears are excellent swimmers and often cross bodies of water, particularly in coastal and wetland areas. Their ability to adapt to human presence and exploit human-provided food sources can lead to habituation, posing challenges for both bears and people.

• Black bears can have cinnamon or brown coats.
• Their curved claws are effective for climbing trees.
• Cubs are born while the mother is in her winter den.
• Autumn feeding can focus heavily on a locally abundant berry or nut crop.

May through September generally covers active-season travel in Alaska, with local salmon timing affecting some coastal opportunities. In New England, spring through autumn is suitable for woodland excursions. Neither region has a universal viewing peak, and food availability can shift activity substantially. Prime viewing opportunities often coincide with berry ripening in summer or the salmon runs in Alaska, which concentrate bears along rivers and streams. Autumn leaf fall in New England can make bears more visible before they den, as they forage extensively to build fat reserves. Early morning and late evening are generally the most active times for foraging.

Forests with dense cover, varied plant foods and secure resting areas are central habitat. Bears also use wetlands, meadows and coastal margins. In Alaska they may forage beside salmon streams, while New England sightings more often involve inland woodland and forest edges. They are highly adaptable and can be found in a wide variety of habitats from sea level to high elevations. Proximity to human development is not a deterrent if cover and food sources are available. In Alaska, they often inhabit temperate rainforests and glacial valleys, while in New England, they frequent mixed hardwood forests and swampy areas.

Plants supply much of the diet, including young shoots, berries, nuts and other seasonal foods. Bears also eat insects, carrion and occasional vertebrate prey. Salmon can be important locally in Alaska, whereas mast crops such as acorns strongly influence autumn feeding in New England. Their diet is highly opportunistic and varies seasonally, reflecting local food availability. They consume a broad spectrum of items, ranging from grasses and forbs in spring to a variety of fruits and insects in summer. In New England, agricultural crops like corn can also be a significant food source during certain times of the year.

Identification

Compared with a brown bear, it generally lacks a prominent shoulder hump and has taller ears and a straighter facial profile, regardless of coat colour. Despite the name, their fur color can vary from jet black to cinnamon, light brown, or even bluish-black, and they often have a white chest patch. A key identifier is their short, rounded claws, which are well-suited for climbing trees. Adults typically weigh between 200 and 600 pounds, but size can vary greatly with region and food availability.
