This morning on my way into work, I heard a short story on Morning Edition on WBUR (one of our local PBS stations) about Snowy Owls at Logan International Airport in Boston. It's pretty common knowledge that they arrive there every winter, and through a cooperative effort of Massport and MassAudubon they are removed to wilder places (often times the Parker Rivern National Wildlife Refuge on Plum Island) both for their protection as well as for the planes.
I though you might be interested in it too. You can read the article here or can listen to it here.
