The canutus part of the knot's Latin name is said by some to refer to the bird's habit of feeding at the water's edge, others say the name refers to it's grunting call.

Knots can double their weight before migration.

There are six sub-species of knot, most of the UK wintering birds come from the Greenland breeding grounds, but some come from North America. In the late 1800's large numbers were shot for food during migration in North America.

These days the American sub-species is threatened by the harvesting of horseshoe crabs where about 80% of the birds stop to feed on crab eggs during spring migration. (Delaware Bay) It is thought the American subspecies might go extinct by 2010.
