Short abstract from the book: The sedge warbler is a fairly common breeding bird in
Denmark, especially in the drier edges of reed beds with shrubs.
Most breeding birds arrive in Denmark in the second half of
April and the last birds depart in October. Passage migrants
are observed in May-June and August-September. The first
sedge warbler was ringed in Denmark in 1923, with the
greatest number ringed in 1995 (700). Many of the recovered sedge warblers were ringed in reed beds in autumn.
The sedge warblers that have been ringed in Denmark are
of Scandinavian origin. From Denmark the birds migrate
SSW, with autumn recoveries from northwest Europe and
the central Mediterranean. In August the mean position is
in northern Germany and in September in Switzerland. A
fast bird migrated 1,198 km in late August from Denmark
to Italy in six days (200 km/day), and a bird ringed on
18 September in Norrköping in Sweden was recovered on
Christiansø the following day (351 km/day). No birds have
been recovered in winter, and only a few during spring. The
few spring recoveries indicate that the return migration follows the same route as in autumn. Most of the recovered birds
were recorded by ringers (89 %).
