The only photographic skill required for using wildlife camera traps, is the ability to choose a good site to place them.
When a sparrowhawk leaves a dead pigeon on your lawn, it is highly likely that she will return to finish her meal the next day. So the canny photographer will place the trap near to the bait. Then it is simply a matter of returning to a warm bed, with the expectation of a series of super shots of a sparrowhawk tucking into her meal the next day.
Or you might just get a shot of a cat stealing the carcass.
