Résumé :	Long-term studies of Tengmalm's Owl on the Munich gravel plain have indicated changes in population dynamics, breeding biology and behaviour of the species in this area in the years 2012 to 2014: an increase of broods in Black Woodpecker cavities and, simultaneously, a decrease of broods in nest boxes together with a move into unusual habitats where Black Woodpecker cavities are available. With Tengmalm's Owl disappearing more and more from the peripheries of the research area and with its reproduction success on the decrease because of the lack of females, the survival of the species in the area is uncertain.
