Bird strike

A bird strike (sometimes called birdstrike, bird ingestion (for an engine), bird hit, or bird aircraft strike hazard (BASH)) is a collision between a flying animal (usually a bird, occasionally bat) and a moving vehicle (typically an aircraft, occasionally high-speed train or automobile). The term is also used for bird deaths resulting from collisions with high-rise buildings, towers (see bird–skyscraper collisions and towerkill) and tall structures such as overhead power lines and wind turbines. A significant threat to aviation safety, bird strikes have caused a number of accidents with human casualties. Nevertheless, the number of major accidents involving civil aircraft is quite low, and the majority of bird strikes cause little damage to the aircraft despite usually being fatal to the bird(s) involved. Efforts have been made to mitigate both the risk and severity of bird strike incidents.
