What am I?
The knot is a medium-sized, short, stocky sandpiper that migrates to the UK in large numbers during winter from its Arctic breeding grounds.
Commonly spotted feeding in estuaries around the coast, the largest numbers can be seen at high tide roosts in the depths of winter.
A long-distance migrant, the knot can travel up to 15,000 km, stopping along the way at least once to feed.
