Walton Balancing Lakes

A lunch time trip to Walton in a very brisk NE wind, circa 15mph+ didn't produce any views of the Bearded Tits. Met Geraldine on site and she advised they've been heard but not see. Guess the wind was too much. I gave it 15 minutes but only heard a Water Rail squeal. I popped up to check if the '2nd' hide was still standing and was surprised to see 2 drake and a female Wigeon with 5 Shoveler and 3 Gadwalls. Not sure I've seen Wigeon here before?
