Walking on Water

We have been birdwatching around Cley Marshes today, first walking along the high walkway across the marsh, built as a flood deterrent. 
There was a small pond to one side which was attracting two Stonechats which were mainly flitting about among the reeds.
This one decided to walk on the ice which hadn't melted in the pond. I sat down to take the shot through the reeds - it was too windy to hold my camera still if I stood up.
