Hey, this is my post!

I took this on Sunday along the Delaware Bay. Several Royal Terns were perched on a series of posts. Once in a while, one tern would fly up to another and force it off the post on which it was perched. This usually resulted in a chain reaction, where the displaced bird would find another tern to displace, and so on and so on. This kept happening despite the fact that several posts weren't occupied. It was fun to watch and photograph.

The sun was behind me when I took this late afternoon shot.
