The picture of this Least Tern harassing an Oyster Catcher was taken at Nickerson Beach, Lido Beach, NY. Nickerson Beach is filled with bird adventures. Both the Least Tern and the Oyster Catcher nest on Nickerson Beach. It is the behavior of the Least Tern to protect its breeding territory by dive bombing all intruders.
It is really exciting photography to be able to go to a place such as this where there is so much bird behavior ready for the camera.

I used my CANONEOS7D with the CANONO 100-400mm lens to make this capture.
