I have been doing some further reading* and I think that the reason that birds don't fly into each other is that they are closer in the tree of life to the quantum butterfly than are humans.
So they incorporate a little of the random fluctuations in their movements and are thus spared the ignominy of admitting to mid air collisions. Flying united excepted.
*I have been reading the Da Da de Da Da Code, Making Money, Rama Revealed, The Ringworld Engineers, The Ringworld Throne, and when there is nothing else around that seem interesting, my lecture notes, coz I've gone back to big school. I've got The Brightonomicon part read right now.
