They are becoming a nuisance in many places and last Sunday, when I was out in Hainburg hunting kingfishers (just for the photo), there was at least one nutria in every small pond. At first we thought (Thomas was with us) that it was always the same, but the differences were quickly identified. As the first one appeared at the old beaver den and also dived right in front of it, we had to ask the internet whether we were seeing a real beaver after all. In the end, it wasn’t a black nose, the ears stick out too far and the white whiskers plus the rat tail and yellow teeth showed that it was nutrias that were up to their mischief there.
