Google and Wikipedia, wonderful tools:
Bird strikes happen most often during
takeoff or
landing, or during low altitude flight.
[7] However, bird strikes have also been reported at high altitudes, some as high as 6,000 m (20,000 ft) to 9,000 m (30,000 ft) above the ground.
Bar-headed geese have been seen flying as high as 10,175 m (33,383 ft) above sea level. An aircraft over the
Côte d'Ivoire collided with a
Rüppell's Vulture at the astonishing altitude of 11,300 m (37,100 ft), the current record avian height.
[8] The majority of bird collisions occur near or on
airports (90%, according to the
ICAO) during takeoff, landing and associated phases. According to the FAA wildlife hazard management manual for 2005, less than 8% of strikes occur above 900 m (3,000 ft) and 61% occur at less than 30 m (100 ft).[
