Talk about misplacing your fears.. Airplanes typically cruise at around 33,000 feet; there are no birds that high. All bird-related accidents happen upon take-off and landing, but even then they are barely a threat. The numbers I heard, in the last twenty years or so, there have been about two hundred deaths world-wide due to birds colliding with airplanes and I'm not sure what percentage of that is for commercial airliners versus general aviation. Birds hitting airplanes is probably the least-likely way you can perish.

I'll even bet $5,000 of my own money that neither you, nor anyone you personally know will be killed by a bird colliding with an aircraft, ever.
