Is the behavior of mammals the same at different times of the year?

Mammals behave differently at different times of the year. In the spring, males of some species of animals arrange duels in the fight for females. In the spring and summer, during the birth and rearing of offspring, mammals lead a more hidden lifestyle. At the same time, animals are active in search of food not only for maturing young animals, but also for their own body in order to accumulate fat before winter. There are animals that make food supplies. For example, chipmunks, squirrels. In winter, some animals hibernate. For example, bears, hedgehogs, gophers. Some are united in herds and flocks. For example, wolves. It’s easier to get food this way.
