A very interesting image, Haim. That has to be the most unsubstantial tern nest that I have ever seen, given that it appears to be in open water. It looks like a couple waves would wash the whole thing away. Nice light, action, detail, and background. I would wish that the rest of the rear bird's beak was visible.
excellent behavior shot with artistic beauty as well. I like it alot, but if i had to nit it seems like for me it could be a tad brighter (on my screen) but really fantastic.
