Why birds don't crash into each other in the skyway

Do birds follow rules in the skyway to prevent head-on collisions with each other? This question was answered recently when scientists pointed budgerigars at each other in an air tunnel. They found that birds have evolved a simple way to avoid mid-air collisions by always veering right and changing altitude. 

“We have investigated how birds avoid mid-air collisions during head-on encounters. Trajectories of birds flying towards each other in a tunnel were recorded using high speed video cameras. Analysis and modelling of the data suggest two simple strategies for collision avoidance: (a) each bird veers to its right and (b) each bird changes its altitude relative to the other bird according to a preset preference. Both strategies suggest simple rules by which collisions can be avoided in head-on encounters by two agents, be they animals or machines. The findings are potentially applicable to the design of guidance algorithms for automated collision avoidance on aircraft.”

This is, of course, evidence that driving on the right side of the road has a natural basis, as opposed to the unnatural custom in Britain.
