Last week I traveled north from Seattle to Fir Island where the Dunlin congregate in large flocks when the tide is right. When you find them they will often, to escape a raptor, take off in large numbers creating patterns in the sky that are amazing and hard to describe. Natural fireworks is as close as I can get. These photos do not do the phenomena justice but I hope they give you some sense of the magic. It is quite a sight to see live and in person.
