People like to build airports on, or very close to, sites that have been used for millennia as resting and refueling stopovers by migrating birds. And this creates a lot of conflicts. The Bird Strike Committee USA estimates almost $1 billion in damages occur annually to American civil and military aircraft due to wildlife and bird strikes. These strikes have also caused the deaths of more than 250 people since 1988.
