The black woodpecker

The black woodpecker, with a red crown, is the largest woodpecker in Europe and is roughly the size of a carrion crow, which is also black. In spring, it is easily recognisable due to the loud “kree-kree-kree” call that it makes whilst in flight. It chips large oval nesting chambers into trees, often beech trees, which can then be used by the boreal owl the following year.
