Red Knot

The Red Knot is a fascinating bird that is known for its long migration and unique appearance. In this blog post, we will discuss the basic description of the bird, where to find it, its habitat, food habits, and some cool facts.

Basic Description

The Red Knot (Calidris canutus) is a medium-sized shorebird that belongs to the Sandpiper family. The bird measures around 8 inches in length with a wingspan of approximately 20 inches. It has greyish-brown feathers on its back and white underparts during non-breeding season while having rust-red plumage on its breast during breeding time. Its beak is straight and sharp which helps them catch their prey efficiently.

Where To Find This Bird

Red knots breed in the Arctic tundra region such as Canada’s High Arctic or Greenland but spend winters mainly along coastal areas of South America, reaching as far south as Tierra del Fuego in Argentina. During migratory periods they may stopover at various wetland habitats along the Atlantic coastlines from North America down to Brazil.


During breeding seasons Red Knots prefer arctic tundras where they build nests among rocks or vegetation close to water sources such as lakes or rivers with high humidity levels due to melting ice close by. For wintering grounds they rely on temperate regions like estuaries or mudflats near beaches providing access to ample intertidal feeding opportunities.


Red knots are carnivores whose diet consists mainly of small mollusks like clams oysters and mussels which it picks out from sand or mud using its long bill probing into sediment searching for these creatures buried just beneath surfaces using an electro-receptive sense called magnetoception thereby adapting well towards tidal changes occurring regularly.

Cool Facts

– Red Knots have one of the longest migrations in the bird world, traveling up to 9,300 miles from their breeding grounds in the Arctic to their wintering sites in South America.
– They have a unique ability to regulate their metabolism and shrink vital organs during migration which helps them conserve energy while flying long distances without food or water.
– In 2014, Red Knots were listed as threatened under the Endangered Species Act due to habitat loss and overfishing leading to a decline in prey availability. Conservation efforts are underway by several organizations around the world.
