The young learn how to survive from their mothers. Many of the young do not live through their first year as there are many dangers, particularly predators. In addition, depending on the weather conditions, food may be scarce and the first winter may be difficult for the young animals. It's important for your personal safety and the welfare of the animals. Another species that should be mentioned is the grizzly bear.
Some areas are closed to all forms of human activity, particularly around Yellowstone Lake.
The bears frequent areas around the lake in May and June as they feed on the spawning trout. Please obey all closure signs for your safety and the benefit of the bears. If you should observe a bear from the road, do not approach the animal. Grizzly sows with cubs are extremely protective of their offspring and will aggressively attack anything that they perceive as a threat to their cubs. You can be certain that she is nearby and will be keeping close watch on her cubs.
