Why do birds fly in circles in the sky

There are three main reasons why birds fly in circles in the sky:

1.Foraging needs. Flocks of birds foraging together are more efficient than foraging alone.

2.Self-defence. When encountering enemies, living in groups can strengthen courage and reduce losses.

3.Save energy. In the process of flocking, the birds can rely on each other's updrafts, thus reducing the energy expenditure when flying.

This phenomenon is especially evident when geese fly south for the winter, forming a "human" or "one" formation, using updrafts to glide and conserve energy.

In summary, birds fly in circles in the sky in groups to improve foraging efficiency, enhance self-defense ability, and conserve energy.

Because of the low carbon, there are introductions to readers, like bees, butterflies, etc., they also have low-carbon behaviors like birds.

The first bird is the most tired, because the latter bird relies on the wind generated when the front agitated wings. Birds fly into specific shapes to save effort, and in the air they form shapes with the help of team flights, reducing the influence of air currents and increasing speed.

Birds are mostly social residents. Going out to hunt and returning to the nest are both in groups and are normal. There are also two types of birds: night and day hunting! If I were to come to us, you would see a thousand or hundreds of birds taking off at the same time.

Look for food. Wait for companions.

Because if you land on the ground indiscriminately.

Predators may be encountered.

Lives are at stake

So usually neither of these situations will go to the ground.

Continue gliding and flying in the air.

This is the gathering of migratory birds before their migration. Such a hovering can attract nearby birds to join the flock and then form a certain number of scales. When many birds fly together, there is less chance of injury.

Migratory birds are birds that migrate periodically with different seasons. Many birds migrate seasonally along latitudes, breeding in temperate regions at higher latitudes in the summer and tropical regions at lower latitudes in the winter.

Winter. In late summer and early autumn, these birds migrate south from their breeding grounds to their winter grounds, and from their winter grounds north to their breeding grounds in spring. These birds, which migrate north and south with the changing seasons, are called migratory birds.

Type of Residence:

Depending on the migratory behavior of birds, birds can be divided into different residence types:

Resident birds: Resident birds are those birds that do not have migratory behavior, they live in their birthplaces all year round, most of them do not even leave their nest area for life, some resident birds will carry out non-directional and short-distance migration, this migration is regular in some cases, such as crows will gather in the urban center in winter, and in summer will disperse to the suburbs or mountains, this regular short-distance non-directional migration is called "drifting".

Other species, such as snowcocks, migrate between high and low altitudes depending on the season, a migration called "vertical migration", which is still a behavior of resident birds, despite its name.

When the bird spreads its wings, it is subjected to the resistance of the air, which overcomes its own gravity, so it can fly freely in the air. The bird spreads its wings and flapps violently, giving a force to the air, depending on the force and the opposite.

Have you ever seen a bird crawling on the ground?
