Massive thunderstorms overnight. There were a few grounded migrants in the bushes in the morning with a Woodcock, 20 Chiffchaffs, four Blackcaps, 70 Redwings, 20 Song Thrushes and three Wheatears and of much more interest, an "Eastern" type Lesser Whitethroat, which unfortunately failed to find its way into a net. Two Long-eared Owls were hunting after dark at the Long Pits. Overhead passage included 31 Stock Doves, three Merlins, a Woodlark, 16 Skylarks, three Grey Wagtails, two Rock Pipits, nine Bramblings, 150 Goldfinches, 20 Siskins and 25 Reed Buntings. A Little Gull and two Arctic Skuas were lingering offshore.
Two Porpoises and a Grey Seal were feeding offshore and in the evening there was an almost continuous presence of Nathusius's Pipistrelles, Common Pipistrelles and Soprano Pipistrelles.
An unusual record was a dead Common Toad on the road.
The moth traps were very productive with 24 Palpita vitrealis, five Gems, four Delicates and a Radford's Flame Shoulder. A Hawthorn Shieldbug was also found in the traps and a Western Conifer Seedbug was found at Delhi Cottage. A Mediterranean Stick-insect was seen in the Observatory Garden.
