NOTE OF EDIT: I added a movie of the cardinal and it appears at the bottom of this post. He does this for hours.
I have been fascinated the last few days with this cardinal's apparently unending ritual. He starts out sitting on the mirror of Rand's truck.
Then, he flies down to perch on the edge of the door, and looks at himself in the mirror.
A few seconds later, he flies up and pecks at his image in the mirror, then lands atop it, only to repeat the process over and over again. The mirror has little streaks from where he has pecked it, and of course, he tends to poop down the door.
He only utilizes the passenger side mirror, and if the Avalanche is gone, then he does his ritual on my car mirror. After several repetitions, he flies off to a nearby bush for a few seconds, and then comes back to start all over again.
