Résumé :	In the National Park Bayerischer Wald, Germany, the reintroduction Ural Owl is supported by 58 nest boxes. Yearly controls gain an insight into breeding numbers of Ural Owl and closely related Tawny Owl. The analysis of prey remains found in the nest boxes gives further information of food composition of both owl species during the breeding season. Data of breeding numbers and food ecology summarized in this study do not allow to suspect any competition between Ural Owl and Tawny Owl.
