Arctic Tern Photo

This photo of an Arctic Tern on nest was taken at Potter's Marsh near Anchorage, Alaska on June 24th, 2006.  This one is sitting on a nest, a nest that's literally 2 feet off of a small parking area.  I got out of the car, and this guy immediately flew up and started hitting me on the head with his/her beak and feet.  I didn't even see him/her until the defense of the also unseen nest. 

Once I got back in my car, it went right back to the nest and ignored me.   I could then watch from a mere 10-15 feet away, and also found out there was a single chick that this bird is sitting on (see next photo).  Taken with Canon 20D, 400 5.6L lens.
