Food for thought about technology/bird proofing aircraft
Quote:

Despite having experimented with everything from electromagnetics to ultrasonic devices to scarecrows, the Federal Aviation Administration (FAA) has yet to endorse one single sensational solution that will keep birds out of the path of an oncoming aircraft. The best bet right now is understanding bird behavior, although an intriguing old pilots’ tale—that radar can scatter birds—may carry enough truth to ultimately offer a viable technical solution to a deadly problem.

Of any species, Osmek said, gulls are most likely to strike planes while crows are the least likely. Flocks of crows have even been seen to change direction to avoid an aircraft. Crows and other "airport-savvy" species don't pose nearly the hazard that migrating birds and young birds do, he said.

"We can never bird-proof anything that can fly," said DeFusco.
He says aircraft design has come a long way since 1987, when a B-1 bomber collided with a pelican and crashed on a training run near La Junta. Three died. The military subsequently redesigned parts of the bomber.

Aircraft designers are continually developing better ways to “bird-proof” airplanes.
The Boeing 777, for instance, has engines that are capable of ingesting four 2.5
pound birds and still produce at least 75% of their full thrust rating. Jetliners also
have heating elements in the windshields, which gives them a certain degree of
elasticity and makes them better able to resist damage from bird strikes.
Windshields are required to withstand the impact of a four-pound bird traveling at
speeds up to the design cruising speed of the aircraft at sea level.
