You uys didn't know about that technique? It is extremely frequent in animal photography, and especially bird photography. How do you think all those great pictures of low altitude fly-bys, sometimes head-on, are done? You simply bait the bird along a given trajectory, do it a couple of times until the bird knows the routine and has grown accustomed to your presence, then do it again and start shooting.
I'm not condoning (nor reproving) the technique, I'm just saying it is quite common with many, many types of flesh-eating animals. And beyond... Why, I myself admit to being guilty of hazelnut-baiting squirrels in local parks to get good pictures!
