I was at the coast on a beach when I saw these little birds, and mean little they where the size of mouse. So I made it my mission to try and capture one with my Nikon D80 with a Sigma Ex 50-500mm 1:4-6.3APODG Lens I took about 80 photos over two days this is one of them. They never sat still very long and would jitter about constantly. If you know the name of these little birds please let me know.
