.... nesting area. And he is dive bombing your head because you are too close to their nest of little ones.

Sit in a distant area outside and try to spot where the nest might be. Then set your lawn chair up in a distant area when you want to relax outside.

Good luck, hope you and the BlueJay can live peacefully this summer.
