Short abstract from the book: The marsh warbler is a common breeding bird in most parts
of Denmark, though less frequent in western and northwestern Jutland. The marsh warblers arrive from the end of
May, and by early September most birds have left the country. The first marsh warbler was ringed in Denmark in 1926, with the greatest number ringed in 1983 (609). Fourteen
birds ringed abroad have been recovered in Denmark. Most
of the marsh warblers ringed in Denmark were Danish and
southern Swedish breeders. During autumn birds have been
recovered in Denmark, southern Sweden (21 August) and
eastern Germany (3 August). A bird recovered in Belgium on
13 August was reported as a reed warbler. One bird ringed in
eastern Germany and four ringed in Belgium in August have
subsequently been recovered in Denmark. A bird ringed in
Kenya on 18 December 1993 was recorded on Christiansø on
3 June 1994, 6,818 km from the ringing site. A bird ringed
in the Czech Republic in May was recovered two years later
in Denmark. Two birds migrated in unusual directions in
spring: one from Falsterbo to Lolland and one from Utklippan
to northeast Zealand. Most of the recovered birds (85 %) have
been recorded by ringers.
