We currently have a half dozen in our yard as I'm typing this (no trees around). They fight all the time, they are huge (think squirrels on steroids) and a few have been pounding at our vents trying to get into our attic (one successfully got in and our roofer had to repair the vents).

Is it just my area? I know squirrels are busy this time of year but they are SO annoying. They aren't even afraid of people.
