Occasionally a camera trap records pictures of an animal as it becomes aware of the camera. It is fascinating to see the eye contact and the behavior that follows. A buffalo might flee, a sitatunga might investigate, and there is no telling what an elephant may do. I lost my first camera trap to what appeared to be an angry elephant.

Maybe elephants can feel curiosity. I would like to think so.
