Bar Tailed Godwit

Knot Calidris canutus (juvenile plumage)

Bar Tailed Godwit


The knot is a dumpy, short-legged, stocky wading bird. In winter, it is grey above and white below - in summer the chest, belly and face are brick-red. In flight, it shows a pale rump and a faint wing-stripe. It forms huge flocks in winter which wheel and turn in flight, flashing their pale underwings as they twist and turn.

Many knots use UK estuaries as feeding grounds, both on migration and in winter, and therefore the population is vulnerable to any changes such as barrages, sea-level rises and human disturbance. Large numbers of birds visit the UK in winter from their Arctic breeding grounds. Knot Bird Facts | Calidris Canutus - The RSPB
