Black Woodpecker nesting cavity

Nesting cavity entrance of Black Woodpecker Dryocopus martius, Hungary, April 2015. In Europe, only Black Woodpeckers make oval-shaped holes like this, in fact, the majority of the holes of this species are this shape. This one was 25m up in an old beech tree. It is fresh, new, as the wood around the rim is still clean and pale.
