Highest Flying Birds
The highest altitude recorded for a bird is 11,300 m. (37,000 ft.), for
a Ruppell’s vulture (Gyps rueppellii), which collided with a commercial
aircraft over Abidjan, Côte d’Ivoire, on November 29, 1973.

So for a bird to claim a new record, it must collide with an aircraft?
Man, that's rough!
