Frequently when I park my car in the back of St. Annes, as soon as I put the parking break on two small birds land on my side view mirror. I think they are male dark eyed juncos. I have no idea what they like about my car, but they spend time frolicking in the wind shield wiper well and flying from the door into the side view mirror on the passenger side. They fly so many times into the mirror that they actually soil my mirror with their saliva or feather oil.
Any ideas on what they are doing? I've seen this three times now.
