The brown bear (Ursus arctos) is a large bear species found across Eurasia and North America. In North America, the populations of brown bears are called grizzly bears, while the subspecies that inhabits the Kodiak Islands of Alaska is known as the Kodiak bear. It is one of the largest living terrestrial members of the order Carnivora, rivaled in size only by its closest relative, the polar bear (Ursus maritimus), which is much less variable in size and slightly bigger on average.
Evolution and taxonomy. The brown bear is sometimes referred to as the bruin, from Middle English. This name originated in the fable History of Reynard the Fox translated by William Caxton from Middle Dutch bruun or bruyn, meaning brown (the color). In the mid-19th century United States, the brown bear was termed "Old Ephraim" and sometimes as "Moccasin Joe". The scientific name of the brown bear, Ursus arctos, comes from the Latin ursus, meaning "bear", and from ἄρκτος arktos, the Greek word for bear.
Description. Brown bears are large and powerful animals, with males typically being much larger than females. Adult males can measure up to 2.8 m (9.2 ft) in length and weigh up to 780 kg (1,720 lb), while adult females measure up to 2.0 m (6.6 ft) in length and weigh up to 350 kg (770 lb). The largest recorded brown bear was a male shot in Alaska in 1950 that weighed 1,003 kg (2,209 lb).
Brown bears have a stocky build, with a large head and a long neck. Their fur is typically brown, but can range in color from black to blond. They have a hump on their shoulders and long claws that can grow up to 10 cm (4 in) long.
Distribution and habitat. Brown bears are found in a wide range of habitats, including forests, mountains, and tundra. They are native to Europe, Asia, and North America. In North America, brown bears are found in Alaska, Canada, and parts of the western United States.
Diet. Brown bears are omnivores and their diet varies depending on the season and location. In the spring and summer, they eat a variety of fruits, berries, nuts, insects, and small mammals. In the fall, they eat acorns, beechnuts, and other nuts. In the winter, they hibernate and survive on stored body fat.
Behavior. Brown bears are solitary animals, except for mothers with cubs. They are active during the day and night, but are most active at dawn and dusk. Brown bears are territorial and mark their territory with scent glands and by rubbing their bodies against trees.
Reproduction. Brown bears are polygynous, meaning that males mate with multiple females. The breeding season is in the spring, and females give birth to 1-4 cubs after a gestation period of 7-8 months. The cubs are born blind and helpless and stay with their mother for about 2 years.
Threats and conservation. Brown bears are not currently considered to be endangered, but they are threatened by habitat loss, hunting, and poaching. In some areas, brown bears are also a nuisance to humans, as they can damage property and livestock.
Conservation efforts are underway to protect brown bears. These efforts include creating protected areas, reducing hunting, and educating people about the importance of bears. With continued conservation efforts, brown bears can be protected from extinction.
