When the news came out on Saturday afternoon that a Red throated Diver was at Rainham Marshes it was a no brainer for me as it was a site tick and a London tick. It was staying close to the foreshore and even came up on the mud. So my celebrations were short lived as it was obvious the Diver wasn't well and oiled, which was a real shame, but today I hear there was another sighting of RTD up further the thames. So maybe it's the same one and it's ok? . I hope so, no one like to see any bird that's sick!.
