It is the most common heron species, according to NABU, and yes, there are some in Karben. On my lunchtime walk I pass a field where two herons have been hunting for a week. I missed the big spectacle because I didn’t have a camera with me, but the 10 minutes yesterday were worth it. First he strutted across the mown field with his head held high and caught a mouse for lunch, then he preferred to move on.
