Why the starlings "dance"?
In the spring, with the arrival of birds, or in the fall, when they, on the contrary, fly into the warm edges, can be seen in the sky, how thousands of feathered individuals are going to the flock and loosen in the sky magic figures. They affect their synchronicity, dynamism, speed and fascinating pyruetics. Call this amazing natural phenomenon by Murmouration.
In one or another, it is characteristic of many species of birds. For example, wavy parrots are knocked out in thousands of flocks in the northeast of the mainland of Australia in search of feed and a waterproof, and in our areas, during migration, you can observe bizarre flocks. However, most often the term "Murmuration" denote dance of the star.
The feathers make a flight in such a way that each representative of the flock can observe all its members, and sunlight freely embraced each bird. Movement occurs on a specific algorithm: birds are not lagging behind, do not cut into each other, but keep the system and keep speed.
How do they manage it – it is not known. How are not known exactly and causes such behavior. But when we talk about the starvators, at least one task of these "dances" is: With the help of them, birds are protected from attacks of predators, since such a move makes it difficult to displeasure a separate individual. As a proof, experts from the School of Experimental Psychology at the University of Bristol refer to the computer game created by them. The pernat in it was asked to the algorithm of motion based on a natural phenomenon. And the main task of the playing, that is, a predator, consisted in catching a virtual squorter. The results of the study confirmed: the more flock, the more difficult it is to catch prey.
Migration of wavy parrots in Australia
About other dance purposes, scientists can only guess. One of the versions is the feature of the behavior of the Skvortsov. It is known that in the flock of birds live as a single organism: they feed together, lay down, accumulate, accumulate for overnight stay or rest. And such flights allow you to quickly exchange information with each other.
Another assumption is put forward: during the murmurization, birds spend much less energy due to the fact that the aerodynamics of flies reduces friction. Therefore, the flashes and migrate very dense flocks.
Unfortunately, when we talk about Murmuration, questions arise more and more. In the meantime, scientists are trying to find answers on them, simple inaders admire this amazing natural phenomenon.
