I went down to the other side of the river yesterday. There were two ducks building their nest right there on the water. Every once in a while a big boat came along and created some rather big waves. The ducks seemed unfazed by this. The female was sitting on her eggs and the male duck took no break swimming to and fro with all sorts twigs and sticks in his beak.
I had to cut the sketching time short as my train was leaving soon and I needed to give myself about 20 minutes to walk back up to the station.
