A quick dash before the evening light disappeared. Although only 30 minutes of proper light left I again found Arthur loitering with intent to see some owls but this time his quest was not met. A Marsh Harrier flew in to harass the Starling flocks that were streaming through. These flocks either departed to the Weaver Bend area or gathered in murmurations above the south-east banks of No.6 tank producing a series of pulsating waves.
A group of Raven were comically sat along the fence overlooking No.3 while below a group of 30 Common Teal had gathered. Over on No.6 were 7 Common Pochard, 20 Tufted Duck, Mallard, 12 Pintail, a few Black-tailed Godwit, Lapwing, Shoveler and Gadwall were present.
