squirrel jumping at the window

This guy just jumped at my window from the bush underneath the bird feeder looked up at me and didn't know what was going on. anybody else have this problem?

I get that with robins, they see the branches in the reflection and wonder why they cant get to them. My deck was covered in droppings because of this one robin would just hit the window, fly back to the rail and go at the window again, I swear he did it for hours.

Probably was a male robin fighting his reflection in mating season.
