About

The red knot or just knot is a medium-sized shorebird which breeds in tundra and the Arctic Cordillera in the far north of Canada, Europe, and Russia. It is a large member of the Calidris sandpipers, second only to the great knot. Six subspecies are recognised.

Fun Fact

Red knots make one of the longest non-stop flights of any bird — up to 9,000 km from the Arctic to Tierra del Fuego — and their survival depends on eating horseshoe crab eggs during a brief Delaware Bay stopover.
