When I parked to go to my nail appointment, I was immediately "attacked" by a blue bird!  I parked close to their nest, and he had a fight with himself in my mirror - too funny!  I didn't catch that on my video - I was trying to move slowly so I didn't frighten him.  Turns out I didn't have to worry about scaring him away - he attacks every car that pulls in, having learned that they all have a "blue bird in a box" on the side of the car...
