I have some that like to bash into my patio window, and dive bomb me when on the deck.

I find a laser pointer keeps them off the deck, and a used racket ball racket for a quarter at the recycle center is very satisfying when they get too close, and they remember it for a long time.

Mine returns to the catch basin in front of my townhouse every spring. Then nests in the cattails.
I get an aerial escort daily on my way to the mailbox.

I don't go back for a shot for another month.
Maybe by that time, assuming they're being protective due to babies, perhaps they will have fledged by that time, and mom & pop will have calmed down by then.

The receptionist did say one woman had been scratched on top of her head by a divebomb.
