When I first found him in the camera's lens I did a double-take. None of the other Tricolored Herons of similar size had yellow/pale bills. He was beautiful and I kept coming back to him (and I took many more photos of him than the other two because he was so interesting).
His bill was a bit smaller than the other two herons' bills, and he might be a touch smaller too, but mostly all three were close to the same size.
I still have several fun photos from Pinckney Island in Hilton Head, SC to post from our trip last June, so I'll keep popping them in now and then. These were photographed on 6/13/2010, and it was very warm!! (Click here for all of the 2010 Pinckney Island posts.)
