Short abstract from the book: The wren is a very common breeding bird all over Denmark.
It is also a common passage migrant and winter visitor. The
first wren was ringed in Denmark in 1921, with the highest
number ringed in 1990 (2,293). The recovered birds were
ringed over most of the country. Most birds were ringed in the
migration seasons: 17 % in spring and 70 % in autumn. The
relatively few recoveries of wrens from the Danish breeding
population (n=51) gives only limited information about the
migration. About ninety per cent of the birds ringed in the
breeding season were recovered less than 5 km from the ringing
site. During winter five Danish wrens have been recovered,
two from abroad (southeastern France).
Passage migrants from southern Norway, southern Sweden
and western Finland have been recovered in Denmark from
10 September, most in October. From Denmark some of the
wrens migrate further SW. The fastest bird was recovered
19 October in northern France six days after ringing (123
km/day). Birds ringed outside the breeding season have been
recovered during winter in Denmark (87 %) and in western
Europe from northern Spain in the west to northern Italy in
the east. In spring birds have been recovered south of Denmark
in northern Germany (2) and Poland (1). Scandinavian birds
have been ringed or recovered in Denmark from March to 21
May, most in April. Seventy-six of the recoveries were live
recaptures. Of 101 dead birds, most had been killed by cats,
collided with vehicles or had been hunted. Of birds ringed as
chicks or juveniles and recovered as dead, 72 % were reported
during their first year of life.
