I managed to squeeze in enough time after work to catch the tail end of the wader roost on No.6 tank before they departed to the Mersey estuary for the evening.
A bunched flock of 657 Black-tailed Godwit were in the centre of the water and only started to spread out after a period of time. A small flock of Dunlin were attempting to hide below the godwits. There were a few Redshank feeding on the far edge of the water with a pair in full copulating mode. Four Whimbrel were settled on the periphery of the other birds but were later disturbed by one of the two Marsh Harrier that crossed over their heads. A third harrier flew up to join the two raptors. A pair of Peregrine on the lip of the blue topped chimney had one of them tearing at its recently caught supper.
A look over the mitigation pools on No.3 tank produced 4 Black-tailed Godwit and a finely plumed male Ruff. An odd Mallard X Common Teal type hybrid was with a small selection of other duck species.
The watch was slightly marred by the irritating midges helping themselves to my free blood transfusions, but a ‘reeling’ Grasshopper Warbler and both Sedge and Reed Warbler helped to ease the pain.
