This week was going to be a repeat, for me, of a week just before the pandemic when I did this trip and the Heysham Warrenpoint surveys in the same week, that seems such a long time ago.

I arrived at the bridge just before 5am and already there are quite a number of moored ships around us. You get loads around the mouth of the river at Rotterdam but we were still 4 hours away from the river so did not expect to see so many here. In fact there were more ships around than there were birds. Only a few Lesser Black-backed Gulls and Gannets were seen before we entered the river.

I only surveyed the starboard side of the river as I was doing the trip by myself. Nothing out of the norm was seen on the way down the river. On the return journey there was a Spoonbill seen feeding on the shore, one I had not seen here before. Only a few gulls were seen on the trip back across to Felixstowe.

I did get excited at one point as it looked there was a seal logging on the surface. However, on closer inspection it turned out to be a gull standing on one end of a log floating on the water. One seal was seen later on briefly poking its head above the surface, this was the only encounter with any mammals.

I would like to thank the captain and crew of the Suecia for looking after me.
