When a fox has had enough to eat, it will play with its food.
Action captured on an infrared trail camera.
To capture some of the action when busting foxes, I use a Contour GPS Action Camera mounted on Rover. It has fixed focus, automatic light adjustment and no zoom. The YouTube clip below is action captured on this camera.
This image, taken with a motion activated camera, shows a fox still very wary about scavenging on the remains of a kangaroo. It took the fox 5 days to be courageous enough to start eating.
