In late April this year I was at Helgoland with my friend Johannes Rydström. (Here you can see his images from the trip; johannesrydstromphotography.com )
To get to the island out in the North Sea you go by boat from northwest Germany, and it takes about 2 hours. The remote island has about 2000 people living there, on the main island there is a bird cliff where the colonies of mainly gannets, kittiwakes and some fulmars breed. There is also the lesser neighbor-island, Düne, which is all made by sand, here we had the seals, waders and many sandwich terns. At Düne, we had this surprising view of oystercatchers being hand-fed by locals (see below). There where many other encounters with unafraid birds, both the gannets were unconcerned by your presence and in the center of the village, just at the market-place redwings was inside the focusing distance all the time. A bird that I here in Sweden experience as very timid, flying away before you even notice them.
The last day, on our way home we visited the Watternmeer coast of northernmost Germany. Here we had views of approximately 50 000 knots flying around like swarms or mowing clouds, just amazing views. The flocks also included bar-tailed godwits, oystercatchers, spotted redshanks, greenshanks etc.
