WHAT A BRILLIANT IDEA I JUST GOT FROM YOUR POST ANNE

Yep train a couple of chickens to sit on your shoulder no matter what so that when stalking an animal and it see`s movement all you need is for one of the chooks to flap its wings and the animal will believe its "only a bird" without being duly alarmed---BANG GOTCHA
One down side being that they may have to wear nappies (diapers)-thanks Anne i`m off to the farm to get a couple haha.You guys in Africa could try half a dozen ox-peckers on tethers haha
