Many For years, people have been puzzled over why birds line up in a key formation for migration.
This was reported by URA-Inform with reference to Aktualno.
This is truly amazing, because nature has come up with an ideal way for birds to cover vast distances.
The study found that each bird, by flapping its wings, provides lift to the bird immediately behind it. Thus, thanks to the key shape, the entire flock increases its flight speed by at least 71% compared to the speed that each bird can develop individually.
The order of building a key ensures energy conservation and optimal teamwork. At the head of the key is the leader, the strongest and most resilient. The flapping of his wings creates powerful air currents, providing additional air currents flying behind. However, even he can be tired. Birds show that sharing responsibility and changing the leader can be key to success.
The second link makes the work of the third easier, and so on. As soon as one goose falls out of the general flock and tries to fly alone, he immediately feels the weight and resistance. Therefore, he returns to the flock to use the lift created by the birds flying in front.
The oldest and weakest birds always fly at the end of the key – there the air resistance is minimal. The birds flying behind literally soar on the air waves that they created in front. Interestingly, the cry that we hear from the key flying in the sky is made only by the birds flying behind. In this way, they support the birds flying ahead and encourage them to keep up their speed.
Birdwatching can teach people valuable lessons about cooperation, support, and mutual aid that they can successfully apply in our lives and communities.
