Interesting walk this afternoon along the River Ely on Peterston Moors starting at Peterston village. 40 species in total, including a Buzzard flipping over and putting its talons up to successfully defend itself against a Peregrine (which gave up and flew off). Also 5 Green Sandpiper, 1 Kestrel, 1 singing Dipper, 6 Snipe, 2 Water Rail, 2 Moorhen, 2 Jay, 2 Grey Wagtail, 2 Grey Heron, 2 Cormorant, 1 Treecreeper, 2 Nuthatch and a male Bullfinch.

Hi Ceri – interesting – this is my WeBS area – I can guess where the Green Sands were – they are regulars at the site and over Winter there. Where were the other water birds please – the Dipper, Water Rails, Snipe and Moorhen please? Did you see or hear the Rails? Thanks. John
Hi John
After emerging from Lanlay Meadows onto the Moors proper, I walked the river until the point where the river and path diverge – roughly ST065773.
Part way along at roughly ST069764 the river is especially winding. All the species you ask about were south of this point and north of Lanlay Meadows.
Snipe – one came up off the river bank (in the winding section). The rest were a little south of this to the west of the river where the field is wetter (lots of juncus). NB not the first field after emerging onto the Moors proper.
Water Rails – both seen, but separately. Both on the river bank emerging from vegetation. First time I have seen them here, but all other visits have been in Jan to Apr period.
Moorhens – seen separately, both on the riverbank, the second immediately south of the winding section
Dipper – stood singing on a log in the river in the winding section
