Southern Marsh Orchid. Two regions, 9 in the first and more in the second in the southern part.
Obviously lots of others, but I noticed this one below, possible a creeper on another plant, and am thinking its a garden plant that has made a bid for freedom.
Banded Demoiselle - lots, in places clouds of them
Azure Damselfly - quite a lot of these - I assume this rather than Common Blue
Large Red Damselfly - about 5 of these
Blue tailed Damselfly 1 seen
Hairy Dragonfly - 1 in the reeds
A large Blue one, whizzing round like a mad thing.
Reed Bunting 3 males, possibly 4
Cetti's Warbler - 2 singing
Chiffchaff 1 singing
Sedge Warbler - 1 singing
Fox - 1 young one
Vole sp - 1 small blackish one by the waters edge. Much smaller than a water vole.
