Why birds never crash into each other in mid-air
Lessons from nature can be applied to aviation with increasingly busy air traffic, says study’s author
Birds always seem to avoid one another, even if they’re flying on what looks like a collision course.
In a study published Wednesday in PLOS ONE, researchers from the University of Queensland decided to look into how this happens.
Their rationale was that birds must’ve evolved over millions of years to have these skills, and it’s possible that we could learn a thing or two about how to avoid possible aircraft collisions. Humans are much newer to flight, after all.
The researchers looked at 10 birds, specifically parakeets or “budgies.” They set the birds up on opposite ends of a tunnel and went through 102 rounds of flights.
They then found out that of the 102 flights, none resulted in crashes.
What’s more, the birds tended to avoid any head-on collisions by always turning right, or in some cases changing altitude so that they weren’t on the same level.
