Hummingbird Because hummingbirds are accustomed to eating nectar from the stamens of the flowers and small insects hiding in the center of the flowers, which are generally too small and very delicate, if the hummingbird rests on the flower, the flower will not be able to support its weight, so the hummingbird has to develop its strange wings. Its long, narrow wings vibrate 50 or 70 times per second, making it possible to see only a faint gray mist. It can fly at speeds of up to 50 meters per second, can fly not only forward, but also backwards, and can fly in a circular circle like the leaves of a propeller.
It sometimes resembles a miniature helicopter, taking off and landing vertically, like an upside-down acrobat, hanging vertically in the air, reaching its beak into the flowers to fetch nectar and bugs.

Hummingbirds can stop in mid-air. Hummingbirds are the only birds that can hover in the air and can fly upside down. The hummingbird has a very special flight attitude, and can control its body to hover in the air during the flight, and sometimes fly upside down.
The hummingbird's wings can flap quickly in the air, and this flapping allows the hummingbird to balance in the air, allowing it to hover and fly upside down. In addition, there are some other birds that can also hover in mid-air, such as herons, icators, etc., which can hover in mid-air by folding their wings to reduce drag.

Hummingbirds and some small climbing birds.
-
The bird stopped in the air and hovered. Hovering is done to observe prey or to eat some still food.
Most birds of prey are able to hover, so that they can observe their prey. There are also bees and birds that can hover and fly backwards, and the main suspect is that Qin Shenfan can eat honey. Other birds that can hover are kingfishers, terns, sunbirds, etc.

The vast majority of birds can't do it, but the "hummingbird" can.
See the following description of hummingbirds:
When flying, the wings flap rapidly, fast, powerful and persistent; The frequency can reach more than 50 times per second. He is good at lingering among the flowers for a long time to "stop flying", and sometimes he can fly upside down.
-
First of all, he has to use silicon wings to make his body not fall in the air, so if he stops, he will definitely fall, so he definitely can't stop in the air and not fly!
-
It should be possible, but only a few seconds of grounding.
-
Birds cannot be grounded in the air.

Answer: Analysis: When a bird flies, it relies on its wings to flap the air to gain flight power, and when the bird stops in the air and does not move, it is affected by the force of the updraft in the air and the balance of gravity of the bird Tips: According to Newton's third law and equilibrium knowledge analysis

The surveillance photographed a bird standing still in the air, and netizens were boiling, what is going on?

Swifts fly in the air almost all of their lives, except for laying eggs.

The legendary bird But it stops and dies.

European Animals Swifts Predation Breeding Life Anecdotal birds fly freely in the air, but they always have a time to land, but some people say that there is a kind of "legless bird" in nature, because it flies all its life until it finally dies, and later scientists really discovered a magical bird.
Since hummingbirds are accustomed to eating nectar from the stamens and small insects hiding in the center of the flowers, which are generally too small and very delicate, if the hummingbird rests on the flower, the flower will not be able to support its weight, so the hummingbird has to develop its strange wings. Its long, narrow wings vibrate rapidly 50-70 times per second, allowing only a faint gray fog to be seen. Its flight speed per second is available. >>>More
The answer is simple, because a bird has wings, and it can fly. >>>More
Due to the changes in nature, the migration of elephants and other animals are sentient. I feel that there will be a huge change here, so many small birds choose to migrate.
The vast majority of birds are small and lightweight, so the damage of bird strikes comes mainly from the speed of the aircraft rather than the mass of the bird itself. With the development of aviation technology, the speed of artificial aircraft continues to increase, the speed of some fighters can reach more than ten times the speed of sound, according to the momentum theorem, a kilogram of bird collides with an aircraft with a speed of 80 kilometers per hour, a force of 1500 Newtons will be generated, and a collision with an aircraft with a speed of 960 kilometers per hour will produce a force of 10,000 Newtons, and the high-speed movement makes the destructive power of a bird strike reach an astonishing degree. >>>More
