Wood mice (Apodemus sylvaticus) are frequent nocturnal visitors to the bird feeders in my garden. I used empty yoghurt pots to prevent the mice from climbing the feeder poles, and provided them with an alternative route which included a small gap, which I increased gradually. The camera was triggered by a home-made electronic gizmo which trips the shutter for a single exposure as the mouse passes through a beam of light, and the mouse was illuminated by flashguns at a very low energy, and hence short duration setting, to which the mice do not react. The tilt-shift lens was deployed with 5° of lateral tilt, to ensure that the plane of sharpest focus ran along the mouse’s flight path.
