I was able to photograph this Sow Grizzly Bear with her two cubs in the Dunraven Pass in Yellowstone National Park. Cubs are usually born between January and March. The female usually has two cubs. The cubs are blind and furless and weigh a pound when they are born. The cubs are weaned when they are about five months old, but they usually remain with their mother for two to three years. Grizzly bear cubs can climb trees until they are about a year old.
