@mlanger It's not the camera, it's a person going to the mouth of the burrow, twice, to "get the shot." It is not ethical. It traumatizes the owls. They either fly away for a time, using energy they otherwise didn't need to use, or they dive into the burrow and don't come out for awhile. Ethical wildlife photographers stay back. If the bird or animal shows any sign of being disturbed, you step back further or go away and try again some other time.
