I was the photographer for the 2007 Waterfest, and took some shots in this class. I was sitting at the very far side of the room completely opposite the owl but he was fastinated by the sound that my camera made. Its digital and was on mute with the flash off but there's still a very tiny little noise. The Owl's and the hawk's seemed to notice. The bald eagle could care less it seemed. Perhaps it noticed, but didn't care.
