Short abstract from the book: The grey plover is a common passage migrant from late July
to November and from March to May. Most birds are seen
in the Wadden Sea.
The first grey plover was ringed in 1951, with the majority ringed in the 1950s. Most of the recovered birds were
ringed on Amager in September–October. Some continue on
as early as August (one recovered in northern France), while
others stay until November. The few recoveries indicate a
migration route SW with autumn and winter recoveries in
France and Britain. Grey plovers ringed in these areas during
autumn and winter have been recovered in Denmark. A grey
plover ringed in Denmark was recovered in Togo in early
October, and a bird ringed in Gambia in November was
subsequently recovered in Denmark. The first grey plovers
arrive in Denmark in the second half of March, though most
do not arrive until May. In spring grey plovers have been
recovered in England (1 May), France (27 April to 30 May)
and Siberia (25 May).
