![]() ![]() Currently, no population projections are made due to the lack of genetic understanding. Some of these threats are overharvesting and gene swamping. Very little is known about this rare color variation, so some potential threats could become an issue for the glacier bear. So, it is possible to see a black-colored bear give birth to a bear with the glacier bears' pelage and vice versa. Gestation lasts 235 days and cubs are born in January to early February. Because of the increasing range of all subspecies of black bears since the last glacier maximum, interbreeding is taking place. This breeding period takes place in June through July. The glacier bear female normally has her first litter by 3–5 years of age. During the fall, the bears eat the starchy roots of ground cones and the variety of berries found in Alaska such as blueberries, salmonberries, raspberries, and cranberries.īreeding habits are much like any other black bear. In some areas, moose and deer are a food source for black bears. During the summer in Alaska, the glacier bear eats the abundant Pacific salmon spawning in the streams. Their diet includes young shoots and roots in early spring. Glacier bears, like all other black bears, are omnivores, with their diets varying depending on the food source available during the season and the location. Glacier bears move into their dens in early winter, which can be an overturned tree, a rock ledge, or a cave. Black bears in general are very capable climbers and can use trees as a place of protection and refuge. The glacier bear habitat is dependent upon food source availability, and they move between forest, meadows, streams, and mountains in search of food and shelter. They prefer forest with thick understory and landscapes with lots of vegetation, but can be found in urban populated areas. Glacier bears share most of the characteristics of black bears such as their habitat preferences, food sources, size, and reproductive cycles. Few studies document the subspecies' range in association with other black bears. This region includes Glacier Bay National Park and portions of Tongass National Forest, a temperate rainforest preserve. Elias and from Prince William Sound to Glacier Bay in southeast Alaska, with a few sightings as far east as Juneau, Alaska, and the Taku River. ![]() The glacier bear's hab itat ranges has been reported to be the Alaskan coastal areas between Cross Sound and Cape St. [ This variation can be seen on individual bears that are often lighter on their backs and shoulders, with their legs and belly being much darker or even black. The subspecies was reported by Dall in 1895. The chief feature distinguishing the glacier bear from other black bears is its pelage (hair coloration), which ranges from silvery blue to gray. ![]()
