Thanks. I was using binoculars when I first saw him....had seen one at the other end of this small pond surrounded by light industrial stuff. But the earlier bird (no pun intended) was just a spec in my 300/1.7 combo (which really is a true bargin price/performance wise).
I was just leaving when I spotted him....he flashed his crest just for a second as I watched. Then I got the camera out and just waited....he ate a fish and then displayed...I visit this pond about 20 times a year and each year always see something unusal. First time for the GH, they apparently only visit this location to breed. I will be watching for young as the other GH I'm sure was a female.
