Short abstract from the book: The dipper is a rare breeder in Denmark with an estimated
population of about 5-8 pairs. However, it is a fairly common
winter visitor with an estimated population of 1,000-1,500
birds. In Denmark the first dipper was ringed in 1955, with
the highest number ringed in 1973 (452). Seventy-four per
cent of the recovered birds were ringed in Jutland, mainly in
east Jutland. One bird ringed during the breeding season has been recovered – a chick ringed on Zealand and recovered
during its first winter season, 1.5 km from the ringing site.
The other recoveries show that Denmark is visited by migrants
from southern Norway and southern Sweden. Norwegian
birds were found in Jutland (81 %), on Funen (7 %) and
Zealand (12 %); Swedish birds were found on Jutland (59 %),
on Funen (3 %) and Zealand (38 %). Surprisingly, two birds
ringed as nestlings in Sweden have turned up in Denmark
as early as late June, both more than 200 km west of their
nest. Most birds arrive in Denmark in October-November;
only a few dippers continue their migration south of Denmark
since none of the birds were recovered south of the country later in the same season. The mean distance of birds ringed in
Denmark during winter and recovered later the same winter
was 2 km (0-10 km, n=13). The mean distance between
subsequent winters was 30 km (0-201 km, n=32), and 66
km for a later winter (0-248 km, n=21). From March to
mid-May dippers have been recovered in the Netherlands (1),
Germany (1), Denmark (25), Sweden (8) and Norway (24).
In Denmark the last bird was recovered on 25 April and in
Norway the first bird was recovered on 10 March. Eighty per
cent of the recoveries were live recaptures. Five birds became
caught in fishing nets, three were killed by cats and seven
collided with windows or vehicles. Of eleven birds ringed as
chicks or juveniles and recovered as dead, five were reported
during their first year of life.
