Résumé :
|
In 1996 we initiated a project aiming at supporting and identifying means to safeguard the dwindling Population of Barn Owls Tyto alba in Denmark, at that time estimated to consist of only about 30 pairs. In 1997 we visited 197 localities on and around the island Als. 105 (53%) were categorized as uninteresting for our purpose. 64 (32%) were considered potential Barn Owl localities, 13 (7%) showed signs that Barn Owls had been present recently, at 6 (3%) one or more Barn Owls were actually seen, and at 9 (5%) we found breeding Barn Owls. At promising localities we put up nest boxes for Barn Owls. In this we have had good advice from Landesverband Eulen-Schutz Schleswig-Holstein, a group working with owls in northern Germany since 1981.
