Different country, different conditions I know, but Sydney airport in Australia had a major problem with birdstrikes as it's built close to wetland areas. They're attempting to change the types of birds living in that area by removing nests, and actually encouraging some native birds which apparently aren't a problem and also by "tweaking the ecology". Apparently birds around the airport used to be culled. Now they're trying to change the way the environment is managed. The Ibis is a huge problem here. They're not as large as a goose though ... I don't think.
