Weekend in Büsum

Büsum is a small town in the north of Germany, very close to the North sea. Me and my family went there, and as we had made no plan for the following days I used on of the days to go birding.
I already woke up at 4AM and then walked the whole day along the coast, in the end about 30km. This is the way I went (also some kilometers back, which makes 30km in the end): Way
On the way I encountered 9 new species for this year, some of them made me really happy!

The new species were Common, Arctic and Gull-billed Tern, Little Gull, Golden Plover, Bar-tailed Godwit, Spoonbill, Bearded Tit, Montagu's Harrier
