The term 'pink-legged bird' is referring to a stilt, which is a type of wading bird with long legs and a long, thin beak. Stilts are found in many parts of the world, including Europe, Asia, Africa, and Australia. They are usually found in shallow wetlands, where they feed on small fish, insects, and crustaceans. Stilts have distinctive pink legs, which help them to stand out in their environment.
