Résumé :	The Black Woodpecker (Dryocopus martius) is described as a key creator of nesting cavities. Nevertheless, data on nest depredation at Black Woodpecker cavities are scarce. We continuously monitored 72 Black Woodpecker tree cavities by means of camera trapping during one breeding season in different temperate Beech forest (Fagus sylvatica) areas in southern Germany. We assessed the frequency of visits of the different predator species at the tree cavities. We found that cavities visited by predators and those which remained undetected by potential predators did not differ according to factors that are assumed to drive cavity selection in order to reduce predation risk. We conclude that, under the conditions prevailing in our study regions, Black Woodpecker cavity nesters cannot substantially further reduce depredation risk by nest cavity site selection.
