Great Blue Heron. Juvenile?

A co-worker called me over today to say there was some kind of crane over in the retention pond. Really?

I came over and saw this Great-blue Heron. Picture taken from our 2nd story window.



I informed him that is was a Great-blue Heron. "Doesn't look very blue.", he said. I figured it must be a juvenile. Note the grey overall appearance and the interesting white tail feathers.

There are other older herons around the complex but this one was a nice change of color.
