Short abstract from the book:
The long-eared owl is a common breeding bird in most parts of Denmark. It is also a common passage migrant and winter visitor. The first long-eared owl was ringed in Denmark in 1914, with the highest number ringed in 1963 (139). The recovered birds were ringed over most of the country. Sixty-eight of the recovered birds were ringed during the breeding seasons, including sixty-four birds ringed as nestlings. During autumn the first recovery more than 100 km from the ringing site is from 26 October in northern France (766 km). The mean distance of birds ringed in Denmark as chicks and recovered during the first winter was 175 km (3-676 km, n=9) and 131 km for a later winter (32-242 km, n=7). The recoveries indicate that birds from the Danish breeding population winter in NW Europe including Denmark, Germany, the Netherlands, Belgium and France. Forty-two per cent of birds ringed as chicks and recovered in a subsequent breeding season were found more than 50 km from the ringing site (mean 51 km, 0-155 km, n=11). The recoveries indicate that Denmark is visited by migrants from breeding populations in central and southern Norway, Sweden and Finland but also from Lithuania, northern Germany and even from Holland. Birds from Scandinavian have been recovered in Denmark from 15 October to late April. Birds ringed in Denmark outside the breeding season have during winter been recovered in NW Europe including Denmark, Germany and Britain. Some of these birds have migrated in a westerly direction, ex. from Christiansø in the Baltic Sea to Jutland, Orkney and Newcastle. The recoveries indicate that long-eared owls are returning to the same wintering site in subsequent winters. Only fifteen per cent of the recoveries were live recaptures. Of 108 dead birds, 22 % were reported as killed in traffic and 5 % had been shot; four in Denmark (before 1972) and one in Germany (in 1965). Of birds ringed abroad and found dead in Denmark, 26 % were reported as killed in traffic and 2 % had been shot.
