Third place: Wood mouse with blackberry by Gary Cox 'I noticed several woodmice and a vole were feeding on seeds falling from the bird table, so I built a nearby enclosed feeding table at ground level just for the small rodents. By gradually raising it a little way off the ground the mice/voles would go up a strategically placed ramp. When they were used to this I replaced the ramp with a blackberry stem which they readily took to. They would often grab an item and run back down the stem carrying it. I placed a few blackberries and hazelnuts on the feeder which were eagerly carried off. The best time to photograph them was very early in the morning using several flashguns which also helped to freeze the movement'
