It is breeding time and papa swan is even more protective than usual. Today another swan entered the lake and papa swan fought him off. After returning to "his" lake, he made sure that the other part of the lake is free from intruders as well. Then I followed the little intruder and he seemed to be a bit exhausted. I walked him to the upper part of the lake which is quite a walk for a swan. At one point he even sat down on the road, as if he was ready to give up. But you don't get to give up when you are with me. He stood up again and after a while, we reached the water.
