Short abstract from the book: Knots of both the Siberian subspecies canutus and the
Canadian/Greenland subspecies islandica pass Denmark
during autumn and spring, and some Canadian/Greenland
knots winter in the Danish Wadden Sea.
The first knot was ringed in Denmark in 1951, the majority in the 1970s. The recovered birds were ringed in July–
October and in April, most on Amager. Furthermore, many
knots ringed abroad have been recovered in Denmark.
One bird from Siberia was recovered in Denmark (26
September) and others were ringed in Finland and Sweden
during migration and subsequently recovered in Denmark.
The Siberian birds continue along the west coast of continental Europe to Mauritania and South Africa. Four birds
ringed in South Africa were later recovered in Denmark (in
August–September and April).
A knot ringed as a chick on Ellesmere Island in Canada
was recovered in eastern Jutland a month later. Another bird
from this population was ringed in Iceland on 10 August and
recovered in Denmark on 1 September the same year. After
moulting, many Canadian/Greenland knots migrate to the
British Isles to winter. Many birds ringed in Britain during
autumn and winter have later been recovered in Denmark,
mainly in western Jutland (in August). Canadian/Greenland
knots return to the Danish Wadden Sea in March and depart
in May.
