A wader is a type of bird that is commonly found in wetlands, shorelines, and mudflats. These birds are known for their long legs, which help them wade through shallow water in search of food. Waders typically feed on insects, crustaceans, and small fish, using their beaks to probe the mud or sand. Some well-known examples of waders include herons, storks, and sandpipers. They are often characterized by their slender bodies and long necks, which aid in hunting for prey. Waders play an important role in their ecosystems by helping to control insect populations and serving as indicators of environmental health.
