Short abstract from the book:
Tengmalm’s owl is a very rare breeding bird in Denmark with a very small and unstable population mainly on Bornholm in the Baltic Sea. The first breeding pair was found in 1968 in north Jutland and in 1979 on Bornholm. Small invasions occur in some years, mainly in eastern Denmark with up to 20 individuals recorded. In total 43 tengmalm’s owls have been ringed in Denmark, the first in 1963. The highest numbers were ringed in 1975 (6), 1986 (6) and 1999 (6). Most birds were ringed on Amager and southern Falster. Very few birds have been ringed at breeding sites; most birds were ringed in invasion years. Only one of the ringed birds was recovered: a chick ringed on Bornholm on 30 May and found dead on 8 July about 10 km from the ringing site. One foreign-ringed bird was recovered in Denmark: a chick ringed in western Finland on 22 May 1989 and recovered on 17 October the same year in northern Jutland (922 km SW).
