See the Bittern? Me neither!
After 90 minutes, the bittern became very active, calling almost constantly (every minute or two) and moving around. I would see the grass moving, and started feeling like I was watching "E.T.", seeing scurrying and no small heron. Finally, after almost two hours, I caught a quick glimpse of the bird! A couple of more glimpses as the bird trucked around the flooded field, and then it came out into a small opening in the grass, head and neck pointed skyward in some sort of display.
The bird eventually moved further away. We took this as a sign to head home, and could still hear the glunk-a-lunking for some distance down the trail.
A couple of days with a combined observation time of almost four hours, and finally I got my year look at #142. Well worth the wait!
