Newly made holes of Black Woodpecker Dryocopos martius. Note that the tree is hollow inside and this is why the bird hacks into it. The bird has not killed this tree as it is already doomed and infested with invertebrates. Photo kindly sent to me by Edward Mayer, taken in a park in Potsdam, Germany.
