Spring has come, everything is recovering, and it's the season for animals to mate.I believe everyone remembersZhao ZhongxiangTeacher isInAnimal World

So, why do most animals choose to mate in spring? Why can't people mate anytime during the year?

Why do animals have fixed breeding periods?

Is it affected by the season?Yes

Most animals have relatively fixed breeding seasons, usually in spring when food, sunlight and reproductive capacity are abundant. At this time, the food source is the best, and the offspring have time to grow and learn survival skills.

Just-born fawns may find it difficult to keep warm. If you are a deer mom, you can raise a fawn in the warm spring and summer seasons rather than in the cold winter, which is easier. But the plan seems difficult.

A wild animal that gives birth at the wrong time, such as when food is scarce, will find it difficult to raise its offspring. So, how do animals know when to start making a living?Winter has passed and spring has come, and the days are getting longer.The slow increase in daylight lets many animals know that it's time to breed

They know that this season of the year is the best time to raise offspring

For example, sparrows, a common bird species, like to nest under eaves and in crevices, and prefer to raise their young birds in spring and early summer

If you observe carefully, you can see that male sparrows' reproductive conditions change. Male sparrows with reproductive capacity have black beaks, while non-reproductive males have yellow beaks. Once the breeding season is over, their beaks will return to their original state.

Many animals choose spring as their breeding season, so that their offspring have the best chance of survival.

Why do people mate anytime?Humans don't have a 'breeding season'

Because we can mate anytime during the year, not reserve it for a specific time. People want to be together, and they crave connection. So they seek relationships, not because mating is best done in this season to survive the winter, but because the desire for intimacy and sex increases.

We belong to a group of continuous breeders, meaning we mate and reproduce throughout the year. Seasonal breeders, such as bears and chipmunks, their fertility and sexual activity change with the different times of the year. These species have females who experience menstrual cycles at specific times, leading to increased sexual activity.

When they are in estrus, their physiology and behavior changes. This change occurs only once a year, but women's libido can be active at any time of the year.Investigations show that many babies are born in specific times of the year

This fact makes scientists think we may have some 'breeding season'

Psychologically, in the cold winter holidays, when the weather is getting colder and we are not used to it, we may crave the warmth of a partner. Have you noticed that women's hands and feet are often cold in winter?That's the reason. Therefore, at this time of the year, our desire for partners may be stronger.

Despite this, it's useless for single dogs

It's also difficult for couples to have children
