Pine marten Martes martes and black stork Ciconia nigra encounters at black stork nests.
This paper concludes that pine martens visited black stork nests in central Poland during the breeding season but were scared away where storks were guarding the nests, and as a consequence no brood losses occurred. Generally, it sometimes happens that pine martens predate black stork nests, but the role of the pine marten as a predator of black stork nests might be smaller than previously thought.

Re: Predators

The avoidance of living in the vicinity of a top predator: the coexistence of the black stork and the white-tailed eagle in NE Poland.
Higlights
1. In the Augustów Forest (north-eastern Poland), the number of the black stork Ciconia nigra over 30 years has strongly declined and the distribution of its occupied nests has changed from almost solitary to clustered.
2. The colonization of the study area by the white-tailed eagle Haliaeetus albicilla was a plausible reason for the observed changes.
3. Storks avoided occupying nests less than 4.6 km from the white-tailed eagles’ nests, which can be defined as a safety distance. The determining role can be played by the fear of the predator more than by direct predation.
