The highlight of the "day" was seen during a torchlight search for crickets in the very early hours when a Nightjar was flushed on a couple of occasions.
There was little sign of any arrivals during the morning with just a Spotted Flycatcher at the Long Pits and 220 Sand Martins and six Yellow Wagtails passing overhead.
A juvenile Yellow-legged Gull was feeding at the Patch.
The aforementioned night search found three male nymphs of Sickle-bearing Bush Cricket and a small increase in the numbers of singing Tree Crickets. At least seven Small Red-eyed Damselflies were found on and around the southern Long Pit whilst moth-trapping produced a Dusky Thorn (only the seventh Observatory record). A Clouded Yellow and a Holly Blue were of note among the butterflies.
Four Porpoises were feeding offashore.
This evening another nymph Southern Oak Bush-cricket was found on the Observatory kitchen window.
Elsewhere two Great White Egrets were seen around the Dengemarsh area this morning.
