Context: Unveiling yet another mystery of avian migrations, a great knot from Russia, belonging to the endangered Calidris tenuirostris (Horsfield, 1821), has found its way to Kerala’s coast, flying over 9,000 km for a winter sojourn.
- The migratory bird that traversed the Central Asian Flyway (CAF) is only one of the two — the other has been sighted at Jamnagar in Gujarat — great knots to be re-sighted in India among the nearly thousand ones tagged with MOSKVA rings in the Kamchatka peninsula in eastern Russia.
- These long-distance migrants stay at the Yellow Sea region and Thailand in southeast Asia before proceeding to their southerly winter grounds ,including Peninsular India along the CAF, one of the nine most important flyways of migratory birds.
- The Great Knot is an international migratory wading bird that travels vast distances between the northern hemisphere breeding grounds and southern hemisphere summer feeding grounds.
- The Great Knot is a medium-sized shorebird with a straight, slender bill of medium length and a heavily streaked head and neck.
- Great Knots occur around coastal areas in many parts of Australia during the southern summer. They breed in eastern Siberia, and when on migration they occur throughout coastal regions of eastern and South East Asia.
