Short abstract from the book: The greenshank is a common passage migrant at coastal
sites, lakes and bogs in June–September and April–May.
In Denmark the first greenshank was ringed in 1949, with
most ringed in the second half of the 1950s and in the 1960s.
Ninety-four per cent of the recovered greenshanks were ringed
on Amager, the majority in August.
None of the greenshanks ringed in Denmark has been recovered in the breeding area, but a few birds ringed as chicks
in northern Sweden have been recovered in Denmark in
late August and early September. Most greenshanks arrive
in Denmark in August, and many stay in Denmark for
some time before migrating S or SW. The mean position is
south of Denmark in September. In autumn most have been
recovered in France and northern Italy. The passage of the
Mediterranean seems to take place over a rather broad front,
and in winter birds have been recovered in southern Europe
and south of the Sahara, in Senegal, Mali, Ghana and the
Congo. In April one bird was recovered in Ghana, and in
early May three were recovered in southwest France and
northern Germany.
