A dunnock singing from the top of a bush.

We go to the mouth of the river Rhine. A rare Iceland gull (see also here) has been reported here. However, we see just herring gulls, a few lesser black-backed gulls, and oystercatchers.
A harbour seal swimming in the river mouth; sometimes diving.
On the beach between Katwijk and Noordwijk one can see there has been a storm recently, as many sea stars have beached; and a necklace shell as well.
