Why birds don't collide with each other in flight

A group of Australian scientists from the University of Queensland wondered why birds never collide with each other and other objects in their path in flight. They were pushed to this by research on the creation of systems that prevent collisions of flying drones, which are increasing every day.

So, studying the algorithm for the flight of budgerigars, scientists noticed that a moment before the collision, they were sure to turn to the right. Another regularity associated with the reaction of birds to an approaching obstacle: they spend no more than 0.42 seconds to correct the flight trajectory.

Any flight is inherently three-dimensional. Scientists have also found that birds are less likely to go up or down to avoid collisions. According to them, this is due to the social status of the birds or their size. However, birds try to avoid an “emergency” situation by going to a safer height.

Birds have been flying for about 150 million years and therefore it is not surprising that they do it much better than any modern drone. But in any case, detailed studies of the mechanism of their reaction to approaching obstacles opens up prospects for the creation of high-speed flying robots.
