I waited all day for the fog to lift but as early afternoon arrived I realised that that was not going to happen! It is only when you travel out on such a day you discover the beauty of the brevity of tones of grey. Visibility was down to about 50 meters but there was still much to see across the estuary with a flock of Dunlin feeding on the edge some Redshank, Bar-tailed Godwits and Teal. Further out and barely visible in the grey were numerous Avocets. This sketch makes you realise how important a horizontal is to orientate the view something missing in this sketch as there is no background making the zig zag on the spit of land into the mud and water slightly awkward.
