CONSERVATION STATUS

Least Concern

The Great Knot has a large breeding range of nearly 1.5 million square kilometers. It breeds in montane tundra in northeastern Russia, and winters in tidal mud flats and similar coastal habitats in parts of the Middle East and southern Asia, the Philippines, Indonesia, and Australia. It has also been recorded as a vagrant in Alaska, and has an estimated population of 292,000-295,000 individuals. This species is in decline and threatened by destruction of important tidal mud flats used during migration and on its wintering grounds. Because of the sharp, recent decline in population and continued destruction of vital habitats, the Great Knot has a conservation rating of Endangered.
