Red Knot
Calidris canutusAlso known as Knot, Robin Snipe, Gray Snipe
Red Knots undertake one of the longest migrations of any bird, traveling up to 15,000 kilometers twice a year between High Arctic breeding grounds and Tierra del Fuego. During spring stopovers on Atlantic beaches, thousands synchronize their arrival with the spawning of horseshoe crabs to feast on nutrient-dense eggs. In winter and migration, their plumage shifts from vibrant salmon-red to a quiet pale grey, perfectly camouflaging them along misty tidal flats.

- Very high
- Why interaction risk is low
- Safe to observe at a normal distance.
- What to notice
- Look for a medium-sized sandpiper with rich brick-red underparts in spring or pale grey plumage in autumn.
- Support conservation
- Give resting and feeding flocks a wide berth, especially during critical spring stopovers.
Responsible observation
- Observation: Scan large mixed shorebird flocks along tidal mudflats during spring and autumn migration.
- Distance: Keep a respectful distance so feeding birds do not waste critical energy flying away.
