Pine Marten Martes Martes And Black Stork Ciconia Nigra Encounters At Black Stork Nests

This study reports five cases where pine martens, Martes martes, tried to enter nests occupied by black storks, Ciconia nigra, in central Poland, Lodz Province. In four cases, when adult black storks or nestlings guarded the nest, the pine marten immediately retreated, and no brood losses occurred. Thus, the pine marten's role as a predator of black stork nests might be smaller than previously thought.
