Just below the Krausstein (in the direction of the Waldsee) there are a few small ponds in the forest, with lots of birdhouses and houses for bats hanging around them. There was a real noise, the different birds outbid each other in their art of singing or insulting! The usual suspects, including jays and buzzards, were unsurprising. But a woodpecker knocking on a tree quite far away turned out to be a black woodpecker (I've never seen it before), much larger than the other species of woodpecker found here!
