Grizzly mom with two cubs in the Denali National Park, Alaska, USA
On average, bear, grizzly females have two cubs in a litter and the mother cares for the cubs for up to two years, during which the mother will not mate. Once the young leave, females may not produce another litter for three or more years, depending on environmental conditions.
Except for cubs and females, grizzlies are normally solitary, active animals, but in coastal areas, the grizzly congregates alongside streams, lakes, rivers, and ponds during the salmon spawn.
The grizzly bear is listed as threatened in the contiguous United States and endangered in parts of Canada.
