Nature Centers often use a silhouette of a flying bird to prevent the

do their best to avoid the silhouette and thereby avoid the window.

I could be wrong, but I don't think that birds simply mate with
whatever bird they happen to fly by. I think there's a little more to
it than that..like maybe some type of agreement between the two
parties.

First the female bird builds a nest, then she lays an egg. Then it's
the male's problem trying to figure out how to fertilize the egg.
