Does beavers change in different seasons?

Yes, beavers exhibit seasonal changes in behavior and activity. During spring and summer, they are more active in building and maintaining their dams and lodges, as well as foraging for food like tender plants and tree bark. In fall, they prepare for winter by stockpiling food and reinforcing their lodges. In winter, beavers remain mostly inactive, relying on their cached food supply and insulating their lodges against the cold.
