As we walked, we passed a birch polypore on a birch tree.
Great spotted woodpecker sound.
Common broom flowers. A bit unusual for January; a sign of a warm winter.
We climb a high sand dune. During the World War II nazi occupation, a German military bunker was on top. Now, it is a viewpoint. Not far from the top, a few flowering common daisies.
A meadow pipit calls.
When we reached the sea, there was much foam.
On the beach, at least fifteen sanderlings.
On this photo, on the right near the floodline, some of these birds. Much too small, as the camera was fit for landscape photos, not for depicting small birds like sanderlings.
As this photo shows, there were many dark clouds on 18 January. Sometimes, rain or hail.
