Short abstract from the book: The dunnock is a common breeding bird in deciduous woodland, farmland edges, parks and gardens all over the country.
It is also a common passage migrant in September–October
and March–April and also a common winter visitor. In
Denmark the first dunnock was ringed in 1922, with the
majority ringed after 1960. Most of the recovered birds were
ringed during migration and only a few as chicks. The recoveries indicate that some Danish dunnocks leave Denmark for
the winter whereas others stay. The migrants fly SSW, and are
recovered in a rather narrow zone going through Germany,
Belgium and central France. Nine Danish birds were recovered in November–January, three in Denmark, one in Belgium
and five in France. Recoveries of Danish and foreign-ringed
dunnocks show that most of the passage migrants come from
Sweden and Norway. The majority of the Norwegian visitors
have been recovered in Jutland, and Swedish birds mainly in
eastern Denmark. From Denmark most dunnocks fly SSW
and are recovered in the same narrow zone as the Danish and are recovered in the same narrow zone as the Danish
birds. In winter the birds have been recovered from Denmark to Spain. The return migration follows the same route as in Autumn. The mean position is in Denmark in April.
