When birds attack

The Boston fern on my front porch has become home to a family of avian squatters. The frantic screeching accompanied by swoops and dives have prevented me from using that entrance as well as doing any yard work in that area. This is what happens when I have the audacity to peer hesitantly through my screen door ( I don't dare open it for fear of losing an eye). Mr. and Mrs. Robin form an intimidating tag team and keep swooping until I back off. Now I know how Tippi Hedren felt.
