Short abstract from the book: The great spotted woodpecker is a common breeding bird
all over Denmark. It is in addition an irregular irruptive
winter visitor. The first great spotted woodpecker was ringed in Denmark in 1917, with the majority ringed in the
early 1970s. The recovered birds were ringed throughout the
year, the majority in October. Five of the recovered birds were
ringed as chicks and 17 as fully grown in the breeding season, but the proportion of Danish birds among the others is
unknown.
The recoveries indicate that the Danish great spotted woodpeckers are residents. Four of the birds ringed as chicks were
recovered within a year of ringing, all less than 19 km from
the ringing site. One bird moved from Zealand to Funen
(116 km) over eight years. The mean distance for birds ringed
as fully grown in the breeding season was 1 km (0–7 km).
Outside the breeding season, Denmark has been visited by
great spotted woodpeckers from Norway, Sweden, Finland
and Latvia. The majority of these birds were ringed at ringing
stations during autumn and could be from breeding areas
further east. Most of the visitors were recovered in October,
and many were young birds in their first autumn.
