These birds know how to party!

I was recently at a party where 3 people walked (or ran in once case) right into a glass sliding door, and 4th into a screen door. They should have cut back non the holly berries.

I could only imagine looking out the office window just in time to see some drunk birds fly into the window and die.... Creepy.....
