I followed a pheromone-tracking male Oak Eggar (the darker individual on the right) to a resting female, near the viewing platform. I've noticed several on the wing the last few days but to the untrained eye they look like a fast-moving butterfly.
Off Mudbank this afternoon - just 2 Grey Herons, 3 Common Gulls, 100+ Mallard, 13 Whimbrel, a juvenile Yellow-legged Gull and a Peregrine.
Green Shieldbug nymph - many thanks to Kev for the id.
This grass is growing in the Duckpond, so under saline conditions. Not sure what it is though.
Annual Sea-blite - again, thank you to Kev
Yesterday's juvenile Yellow-legged Gull was again present off Mudbank but I couldn't get close to it.
