I bought "waterproof" bins after the Sea Empress disaster as counting birds in driving rain is not much fun at the best of times, but misted up bins are worse than useless!
It feels rather like that today (without the smell!), but 4 male & 1 female goosander, 6 female goldeneye & 1 male, 1 male pochard, 45+ mallard, & approx 70 canada geese make up for that!
If I missed anything blame the wind!
