brain damaged cardinal flying into window repeatedly

brain damaged cardinal flying into window repeatedly a video by skippy haha on Flickr.

the internet tells me that this male cardinal sees his reflection in the window, thinks it's a rival cardinal, and tries to air-fight him.

over and over. 

for hours every day.

this idiot cardinal flies face first into the window, smacks his face, goes back to a branch, and flies again face first into the window.

the internet tells me to put a piece of paper over the window so he can't see his reflection.
i think maybe i'll just let darwin take care of this guy.
