American Black Bear (Ursus americanus) lives in temperate forest across North America. It feeds on insects & nuts. Its conservation status is Least Concern.
Fascinating facts about the American Black Bear
- American black bears can sprint up to 30 mph, a speed that lets a 120-lb (54 kg) bear flip a 310-lb (141 kg) rock with a single foreleg, showing how their muscular forelimbs turn raw power into rapid bursts for escaping danger or catching food. This speed, combined with their dexterous paws that can open screw-cap containers, makes them surprisingly agile, highlighting why they can thrive in both dense forests and human-adjacent areas.
- Genetic studies show American black bears split from a common ancestor with brown and polar bears about 5.05 million years ago, and from Asian black bears 4.08 million years ago, indicating they have been evolving separately in North America for millions of years. They retained arboreal, omnivorous habits while larger, more specialized bears went extinct at the end of the Pleistocene, underscoring the role of dietary flexibility in their survival.
- Black bear cubs are born naked, blind, and weigh only 200-450 g, the smallest newborn of any placental mammal, yet they stay with their mother through two winters, emerging in spring at 2-5 kg before weaning at 6-8 months. This prolonged dependence allows mothers to teach.
- The IUCN lists the American black bear as Least Concern because its population is estimated at twice the combined total of all other bear species, with 339,000-465,000 bears in the United States (2011) and 396,000-476,000 in Canada (mid-1990s).
- A male black bear from New Brunswick shot in November 1972 weighed 409 kg (902 lb) after dressing, implying a live weight of about 500 kg (1,100 lb) and a length of 2.41 m (7 ft 11 in), making it the largest wild individual recorded.

About the American Black Bear
Through the misty dawn of a forest glade, the American Black Bear emerges, its sleek fur a shadowy silhouette as it pads silently across the underbrush, driven by an insatiable quest for sustenance. With each deliberate step, it weaves a seamless path through the dense foliage, its paws barely disturbing the leaf-strewn floor as it embarks on a ceaseless journey to unearth the secrets of its woodland realm. As it moves, the bear's rugged beauty is tempered by a quiet intelligence, its eyes gleaming with a deep understanding of the natural world it inhabits.
