Explanation

In mammals that are seasonal breeders, females are receptive to mating only once a year during a specific period. This behavior is known as "seasonal estrus" or "seasonal heat." During the receptive period, females exhibit behaviors and physiological changes indicating their readiness to mate. The seasonal estrus, also spelled as the oestrous cycle, is the reproductive cycle that occurs in most mammalian females, excluding humans and certain primates. It consists of a series of hormonal and physiological changes that prepare the female for reproduction.
