At the risk of you seeing how badly the windows of the atrium need to be cleaned , I'm going to share some funny pictures with you.  We have our 5 birds loose in the atrium, and I happened to notice (in all the dirt of the windows) that evidently Chip, our neurotic Cockatiel, has attempted to escape a few times.  See if you can find his Farah Fawcett style body print on the glass!
