This is lovely Andreas. I think you should buy a membership so that the thumbnail shot comes up in the avian home page. By doing so ,a lot more people would look at your images. It is $20.00 well spent!
I love the chicks and the diagonal line created by the rocky shore. I might boost the contrast just a bit on the adult tern as the black head looks a bit washed out.
An excellent image. well done,
Gail
