Tawny Owl

Short abstract from the book:
The tawny owl is the most common owl in Denmark, breeding all over the country except western Jutland and some islands such as Samsø and Bornholm. The first tawny owl was ringed in Denmark in 1917, with the highest number ringed in 1977 (408). Eighty-nine per cent of the recovered birds were ringed as nestlings, the majority in May. The tawny owls are very sedentary. The mean distance between ringing and recovery sites of birds ringed as chicks is 7 km (0-205 km, n=617); only 5 % were recovered more than 5 km from the ringing site. Most birds disperse during their first autumn. The mean distance travelled by birds ringed as adults was 1 km (0-15 km, n=51). The mean distance between ringing site and recovery site in a subsequent breeding season of tawny owls ringed as chicks was 7 km (0-65 km, n=371). With one exception, none of the recovered birds dispersed longer distances over water. The furthest known passage over water was over Grønsund between Bogø and Falster, a distance of at least 830 m at the most narrow point. Eleven per cent of the recoveries were live recaptures. Of 622 dead birds, 28 % were reported as killed in traffic and 2 % had been shot (mainly before 1962).
