When winter comes, I always visit the beavers’ habitats on the stream. Unfortunately, they never go out to meet me. I can go for the ice, which was created on the beaver ponds. The area is relatively extensive. Beavers have lived in it for many years and nobody bothers them there. Trees flooded with water dry up most. I noticed that this is a very favourable habitat for the black woodpecker. Herds move upstream each year farther away. There, however, a man tries to stop him. The dams are systematically dismantled there, and the beavers repair them again. it has been going on for many years.
