In winter, finding a meal can be a life-threatening challenge for many creatures. Iolo Williams investigates how wildlife avoids starvation when sustenance is scarce by looking back at some of the best seasonal stories from Autumnwatch and Winterwatch. In north Wales, many wading birds are drawn to the abundance of food on the shorelines of the Menai Straits. Among them, the aptly named turnstone finds food that others can’t reach by lifting heavy rocks with its strong neck and beak, rummaging through the pebbles in search of tasty invertebrates. Many of us put out food for wildlife in our gardens, but photographer Richard Bowler managed to attract a real rarity - a highly elusive polecat. Using cameras that trigger automatically, and some irresistible snacks, he captured some amazing images of one individual that is a real character.
