Short abstract from the book:
The hooded crow breeds all over Denmark, whereas the carrion crow breeds mainly in southern Jutland. Outside the breeding season many hooded crows visit Denmark. Of 5,289 ringed crows, only 8 were carrion crows. The first crow was ringed in 1916, with the majority ringed in the 1960s and early 1970s. Twenty-five per cent of the recovered birds were ringed as chicks. The majority were ringed from October to April. Most of the Danish hooded crows are residents. Only two birds ringed as chicks have been recovered from abroad (one in Britain and one in the Netherlands). The mean distance between ringing and recovery site of the remainder was 15 km, and 70 % were recovered within 10 km of the ringing site. From October to April, Denmark is visited by hooded crows from Norway, Sweden, Finland, the Baltic Countries and Russia. The majority of the migrants probably stay in Denmark throughout the winter, since only a few of the ringed birds have been recovered further south. Thirty-three hooded crows ringed in Germany, the Netherlands and Belgium have, however, been recovered in Denmark outside the breeding season.
