Like Something In A Horror Movie, Swarms Of Birds Invade This California Home [VIDEO]

What would you do if swarms of birds invaded your home? Dozens of them flying inside your house and pooping everywhere? Like something out of a horror movie (remember Alfred Hitchcock's "The Birds?") swarms of birds have invaded this California home.

Since the birds are coming down the chimney, why can't Shirley Brown, the homeowner, cover the top of the chimney so the birds can't get in?  Am I missing something here?  I don't envy her cleaning up their mess. Yuck.
