Jon Holt and I had only a few brief flight views after a long watch but we knew there was one
Bittern inside reedbed. There was a good layer of snow over ice in shallows but it was rapidly
thawing and luckily one appeared just in time to capture some snow in photos!
This bird walked quickly across the ice and didn't get sharp pics of this. Have reviewed previous
pics and unless just the light, this one has a yellow iris yet previous pics show bird with
mahogany coloured iris. Indicator of age?
