5 Waders - Knot Calidris canutus


Knot Calidris canutus  (see pictures below)
Standing knowledge is that Knots wintering in NW Europe belong to the Greenland race islandica.
Adult birds return after breeding to NW Europe from the end of July onwards and undergo a
complete moult in the months that follow. Juveniles arrive from the latter part of August onwards.
The Waddensea in The Netherlands and Germany is of crucial importance for this population.
Greenland Knots especcially have suffered greatly from mechanical Cockle fisheries which is now
largely forbidden. Greenland Knots leave Holland in the 2nd half of April when still in winter plumage.
Nominate
canutus , the Siberian Knot, breeds in Russia on the Taimyr peninsula and winters in West Africa,
in particular on the Banc d'Arguin in Mauritania. These birds use the Waddensea as a staging area on
the way to or back from Taimyr to 'refuel' used up fat supplies during May and August. When they arrive
in spring they are already in breeding plumage.

The Knots wintering in the Rhine-Meuse delta in The Netherlands belong to the Greenland-
race islandica. By the end of April they have left or are about to leave for the breeding grounds
safe for a small number of 2nd calendar year birds. These young birds begin moulting their worn
1st winter plumage into their 2nd winter plumage as can be seen on the pictures.
