The black woodpecker

dryocopus martius
The largest of our woodpeckers is very well adapted to different types of habitat, but it prefers beech forests that also include spruce and pine.

It crafts its nest hole in the trunks of thick, tall beeches, and rears its offspring therein. Once the woodpecker leaves its nest hole, it is usually quickly taken over by other bird species, squirrels or martens.

During the summer, the black woodpecker's diet consists mainly of ants that live in the wood under the bark. In winter, it mainly raids forest ant hills on the ground.
