An afternoon photographing at Delfzijl

Today I spent spent some hours photographing Common Tern, Sterna hirundo, Greater Ringed Plover, Charadrius hiaticula and Common Sandpiper, Actitis hypoleucos, at Delfzijl, Groningen. The pics of the plover and tern(s) turned out quite well. The sandpiper wasn't that good.
