Short abstract from the book:
The blackcap is a very common breeding bird all over Denmark, breeding in most forest types. The birds arrive in late April and the last depart in October. In Denmark the first blackcap was ringed in 1925, with the highest numbers ringed in 1987 (2,136) and 1995 (2,114). The majority of the recovered blackcaps were ringed during migration in May and September-November. The blackcaps are of Danish, Norwegian and Swedish origin. Birds ringed in western Denmark migrate mainly west of south and birds ringed in eastern Denmark east of south, indicating that passage migrants in Denmark are from at least two different subpopulations. Birds from the Danish breeding population show the same pattern: birds ringed in western Denmark (mainly ringed as chicks) mostly migrate west of south and birds ringed in eastern Denmark (mainly birds ringed as adults) mostly east of south. The mean position of birds recovered east and west of 12°E show different timings of migration: the autumn migration of western birds seems to take place later than that of eastern birds, and the winter quarters seem to be more northerly. In spring western birds arrive in Denmark earlier than eastern birds. Several birds ringed south of Denmark in autumn (Belgium (13), Germany (5), The Netherlands (2) southern England (1), the Czech Republic (1), Austria (1) and Poland (1)) have migrated in a northerly direction during the same autumn. Birds ringed in Denmark in the autumn have been recovered the subsequent winter on Orkney and in Lithuania and Sweden. A bird ringed in northern Jutland on 17 October was recovered in Iceland on 29 October the same year. Most of the recovered birds were recorded by ringers (58 %). The most common causes of death are hunting and collisions with windows.
