Finally managed to get a day in the field. Went to Shellness and Swale Nature Reserve. Ebird list HERE. Highlights included the White-fronted and Brent Goose spectacle, Barn Owl and nearly 70 Red-throated Divers on the sea- several in summer plumage.

A few of the Red-throated Divers. The Thames Estuary is the main UK wintering area for Red-throated Divers. Aerial surveys have estimated up to 22,000 birds (peak population abundance)
