Bird strikes are a very common problem. Airport management goes to great lengths to try to discourage birds from being in the area but there's only so much that you can reasonably do.

Terminal information services that pilots hear before departing or arriving at an airport regularly have a "notice to airmen, birds on and in vicinity of the airport" advisory.

The real problem is if the bird strike causes an engine fire, which it generally doesn't. That said, it can often cause some minor damage and take a plane out of service for a while.
