So... there's this bird...

And it's beating itself against the window in the basement.

It isn't frightened by our visage on the other side, only focused upon its reflection as a potential aggressor. After all, he dives at it, and the other dives as well. He shows his plumage, puffing his feathers and trying to look all the larger, the other copies his stance. He flies beak-first into the window, and only gets back a pained beak and scrabbling feet for his pains.

He gives up for a time, pulls away from the window, and I have silence- it's so nice, I don't even notice that the incessant beating isn't there until he begins again.

I worry about the cardinal, how he might do this all summer and end up with a small concussion- so difficult that it may string his internal compass out of whack and be unable to fly south for the winter.

Gah, he'll probably be fine. I should go get some breadcrumbs for him.
