onion721: I find some deer will back off, while others are curious. I've had deer, elk and moose come up and nuzzle the camera. Some have spent a fair bit of time checking it out. Bears just love to mess with the cameras. Some of them almost seem to suggest you don't have the camera at their favorite angle. Older coyotes usually disappear pretty fast, but the young ones don't seem to care. I had a set of lynx kittens put on quite a video performance.
