You have Cardinals in your yard and they are looking to nest! They are extremely territorial and are chasing off their own reflection they see in either your mirror or on sunlit glass. The female will be a tan color with an orange beak and the male is bright red. They are beautiful birds to watch.
There isn't much you can do about them other than move your car or cover up the glass/mirrors. I don't think the bird will hurt itself. It will more likely decide to put its nest further from your vehicle to get away from having to defend the position.
you are exactly right about the male cardinal! they are so territorial! we had a beautiful male hanging out on a high stairwell window on the front of our house. The nest was (still is I think) just beside the window. That crazy red bird fought himself on the window for about 2 months. we tried everything as far as covering the window from inside and out (which was difficult considering its location). the attacks slowed but he still went at it at least once per day for weeks and weeks.
Here is my crazy red bird. We eventually got used to hearing him and would be happy he was still around. Haven't heard from him lately so now I'm worried about him.
