Herons along the Olentangy River

These pictures were take 1/8/06 with a Nikon D70 camera and a Sigma 500mm lens.
The Black-Crowned Night-herons were first reported by Dave Horn.To see the Herons, go to the back of the Drake Union on the campus of the Ohio State University. The Drake sits between the Olentangy River and Cannon Drive. Cannon runs north/south between King Ave. and Woody Hayes Drive. There are meters in the lot at the Drake and in the lot south of the Lincoln Tower Dorm.
We observed the Herons on the 7th of January without the aid of a scope and without the camera. We counted 10. When we returned on the 8th with the scope, we saw 9 Black-crowned Night-herons and one Great Blue Heron. Some of the Black-crowneds have the juvenile plumage.
Can you find the Great Blue Heron?
