Great Northern Diver absent when I arrived but flew in over the lower reservoir, over top bank and was back on the lower reservoir when I left.
Also seen: two pairs Common Sandpiper, 3 Redshank, Great Crested Grebe, one Oystercatcher, pair Tufted Duck, Mallard with ten ducklings as well as one with two.
Great Northern Diver still on the lower resvr. I went around 6am and couldn't find it. Mark Rigby saw it at some point later in the morning. I went again around 5pm and it wasn't on view (starting to get a complex.....!). Then it flew in from the Delph end of the valley! 1pr Oystercatcher 1 Redshank 1 Curlew 4+ Common Sandpipers 1 Cormorant 1 White Wagtail on top dam 2 Swallows 1 Willow Warbler 1 Reed Bunting
2 Great Crested Grebe 6 Common Sandpiper 2 Oystecatcher 2 Redshank 5 Mallard, one female with 9 duckling
Is the great northern diver showing any difference in plumage? I don't know anything about ageing of divers or how soon the reach adulthood, but presumably it can't stay a juvenile for ever so perhaps it's showing signs of adult, sub-adult or 2nd calendar year plumage?

The Great Northern Diver was still enjoying life on a somewhat calm lower reservoir.
