Short abstract from the book:
The jackdaw is a common breeding bird all over Denmark, and a common passage migrant, mainly in October and March. In Denmark the first jackdaw was ringed in 1917, with the majority ringed in the early 1950s and late 1980s. The recovered birds were ringed in most parts of Denmark, and the majority were Danish birds ringed either as chicks or as adults in the breeding season. The first young birds have left the colonies by the second half of June. In this month the mean distance is 1 km, in July 6 km, in August 14 km and in September–November 38 km. The earliest bird recovered abroad was from the Netherlands on 2 November. The migrants mainly fly WSW and have been recovered in the Netherlands, Belgium, southern England and northern France. However, only a few birds leave Denmark and during winter only 6 % have been recovered more than 200 km from the ringing site. Passage migrants from Norway, Sweden, Finland and the Baltic countries have been recovered in Denmark.
