What is a "knot"?

A knot is a migratory shorebird that belongs to the sandpiper family. It is known for its compact and sturdy build, with a short neck and a straight bill. The plumage of the knot varies depending on the season, with a grayish-brown upper body during the breeding season and a striking reddish-brown coloration during the non-breeding season. One of the most fascinating aspects of the knot is its incredible long-distance migrations. These birds undertake impressive journeys, traveling thousands of miles each year from their breeding grounds in the Arctic tundra to their wintering grounds in coastal areas. During migration, knots form large flocks that fly in synchronized patterns, creating breathtaking aerial displays. They rely on coastal mudflats and estuaries as important foraging areas, feeding on small invertebrates such as worms, insects, and mollusks. The knot's adaptability, endurance, and remarkable migratory feats make it a truly remarkable species in the avian world.
