Observers: Frank Duff, Allyn Chambers.
A very hot and dry day with temperatures peaking at 28 degrees . On No 6 were 11 Black-tailed Godwit having a siesta and 2 Green Sandpiper on the little pool. Elsewhere, one Sparrowhawk, Sedge Warbler still singing, a calling Reed Bunting and a Chiffchaff. Most of the warblers seem to have now gone. Large numbers of gulls on the River Mersey at low tide along with good numbers of Curlew, Black-tailed Godwit, Dunlin, a few Oystercatcher and 21 Cormorant. Lots of hirundines and many Swifts mainly over the south side of No 6.
A horrid black sludge was being pumped today into No 6 tank through both pipes. Pumping used to stop by May but may well be continuing into the summer because of the proposed deepening of the MSC to pave the way for the ‘Atlantic Gateway Project’ or, the need for deeper mooring for the carrying of the materials for the wind farm with construction beginning next autumn apparently. Whatever the reason, this continuous pumping has had an effect on potential of No 6 for nesting Little Ringed Plovers and Avocet.
