can sleep and mate in the air, flying for ten months without getting tired, what kind of bird is so powerful?
can fly continuously for 10 months without stopping, can sleep and mate in the air, Swift is so powerful.
Swifts usually refer to Swifts belonging to the order Swifts in the order Swifts. They are one of the fastest flying birds. As early as 50 years ago, ornithologists have discovered the amazing flying ability of Swifts, but due to limited technology, they have not yet been able to come up with the answer "how long can the Swifts fly continuously".
In 2016, ornithologists launched the "Swift Tracking Survey Project" and installed tracking instruments on 13 Swifts, and found that some of them had been flying for 10 months without landing. Ornithologists speculate based on the tracked data that perhaps the Swift's continuous flight time is much longer than 10 months.
In addition, ornithologists also discovered that the Swift can even mate and sleep during the continuous flight , which is incredible.
Can mate and sleep in the air, how does Swift do it?
Swift has a long life span of 21 years, but it has been flying most of its life, with a cumulative flight distance of about 800,000 kilometers , and the distance between and the moon and the earth is close to . Swifts can not only "eat and drink Lazarus" in the air, but also mate and sleep in the air, so they are called "birds born for the sky" .
The reason why the Swift can continue to fly for a long time,Thanks to their unique structure.
Swifts are small and light, with wings larger than their body , the body is like a scythe when the wings are spread. This unique structure can save energy during flight and continue to fly for a long time, which is also effective Ensure that they are flying at a high speed of up to 110 km/h.
The small body and the flying speed equivalent to that of a car enable them to easily prey in the air, fly by and drink water easily on the surface of the water, and are extremely powerful.
Like most birds, the Swift does not let the feces stay in the body for too long. It is almost "released as soon as there is" when flying in the air, so it is not difficult to understand the excretion of the Swift in the air.
It is no wonder that Swifts "eat and drink Lazarus" in the air. After all, other birds can do it, but it is incredible to mate and sleep in the air.
Actually, the mating method of the Swifts is somewhat similar to the aerial tanker . Two Swifts that are about to mate only need to glide and stay stable while flying, and can complete mating by gliding a short distance after touching the cloaca. , the mating process is very short.
Swifts can "sleep" in the air because they use "half-brain slow-wave sleep" unique sleep method, that is, half of the brain is sleeping and the other half of the brain is still awake, keeping the body flying , Instead of sleeping with eyes closed like most animals do.
It is worth noting that the speed of Swift will decrease when it is sleeping, and will fly higher than when it is awake to ensure flight safety.
The world is big,Why doesn't Swift land to rest?
After the movie " A Fei Zheng Chuan" was released, the "footless bird" has only landed once in a lifetime and attracted many people's attention. No, they have been flying all their lives and rarely live on the ground, so Swift is also known as the "footless bird".
In fact, ornithologists have found that Swifts are not suitable for survival on land. In other words, Swifts landing on the ground is equivalent to sending them to death. This is because the Swift’s claws have evolved. Short and weak , unable to support the body to walk on the ground, and with four toes facing forward, unable to stand at all. Once landing, it is difficult to take off again. Even if landing, use your toes to hook the wall to rest. If you encounter an eagle on the ground Waiting for the natural enemy, Swift can hardly escape the attack. Doesn't this mean sending him to death?
Therefore, Swifts rarely fall to the ground except for feeding their young during the breeding period.
Extended reading: Swift, who never flies, is actually "the favorite bird of the Chinese"!
The Chinese have a special feeling for Swift, and Swift is deeply loved by the Chinese people. In 2015, the Asia-Pacific Environmental Protection Association and other domestic and foreign organizations organized the "First International Swift Conservation Conference", established a special organization for the protection of Swifts, and passed the decision to give Swifts the title of "the Chinese's favorite bird". Our awareness of protecting Swifts has gradually increased.
In the eyes of the Chinese, the Swift is the representative of auspiciousness. It is the natural enemy of pests, the protector of forest and farmland, and the good friend of people. The Swift symbolizes a good life and beautiful love.
Swift was written into poetry by countless literati, and painted into calligraphy and painting. People sang and praised her with words and songs; the word "Swift" was frequently used as a name; 1999,Macao returned to the motherland with Swift as the mascot ; in 2008, when Fuwa Swift "Nini" appeared as the mascot of the Beijing Olympic Games, the spirit of Swift will be passed on forever.
