The White Wagtails (a minimum of 3, possibly more), were feeding around the back of Stones Island, along with several Pied Wagtails. Here's a picture of a male and a female.

Unfortunately, White Wagtail can't be added to the "year list" as it isn't a species, it's just the European race of the British Pied Wagtail, but I did manage to add another 2 species with a Common Sandpiper and a beautiful breeding plumaged Dunlin being seen.
Other species seen included: Little Ringed Plover, Lapwing, Great Northern Diver (breeding plumage, but distant), Black-headed Gull, Coot, Mallard, Canada Goose, Great-crested Grebe, Chiffchaff, Willow Warbler, Blackcap, Dunnock, Oystercatcher (2) and Redshank (2).
Year List update:
134 – Common Sandpiper
135 – Dunlin
