The term 'pink-legged wading bird' is referring to a stilt, which is a type of bird that has long pink legs and wades in shallow water. Stilts are found in many parts of the world, including Europe, Africa, Asia, and Australia. They are usually found in wetlands, such as marshes, ponds, and lakes. Stilts feed on small fish, insects, and crustaceans, and they use their long beaks to probe for food in the mud.
