<P> A bird strike--sometimes called birdstrike, bird ingestion (for an engine), bird hit, or bird aircraft strike hazard (BASH)--is a collision between an airborne animal (usually a bird or bat) and a manmade vehicle, especially an aircraft . The term is also used for bird deaths resulting from collisions with structures such as power lines, towers and wind turbines (see Bird--skyscraper collisions and Towerkill). </P> <P> Bird strikes are a significant threat to flight safety, and have caused a number of accidents with human casualties . There are over 13,000 bird strikes annually in the US alone . However, the number of major accidents involving civil aircraft is quite low and it has been estimated that there is only about 1 accident resulting in human death in one billion (10) flying hours . The majority of bird strikes (65%) cause little damage to the aircraft; however the collision is usually fatal to the bird (s) involved . </P>
