Our female cardinal gets territorial this time every year.  She has been attacking her reflection in our kitchen window for the past three days.  As I started out our garage door this morning, I noticed she was perched on the rear-view mirror of my truck.  She would fly at the mirror, thinking that her reflection is another female.

I believe the female bluebird is now sitting on eggs.  They moved their nest to a different nestbox after the tree swallows arrived last Sunday.
