My instructor in a local threat management course spent a lot of time on this topic last week. On the forums we mention this quite a bit. What is 'not prey'?
We discussed good examples of 'not prey' in nature. Yes, there are leopards, lions and others in the predator column and gazelles and zebras .... in the prey column. But there are many vegetarians and non predators that do not fall into the prey column.
Cape buffalo, elephants, hippos and similar animals are 'not prey'. The big cats rarely attack one of these types of animals. They are alert none-the-less (condition yellow) and defend themselves and their offspring viciously if provoked. Word gets around to the predators to find some easier prey.
How to be 'not prey'? Well, first, do not look like food to a predator. Look like food and you may be eaten. Walk tall, look around, project confidence. Do not walk around wearing headphones, talking on the phone, head down, reading or otherwise unaware. A predator's job requires that he notice these things. Oh, and stay away from known predator hangouts.
Any thoughts on this out there?
