Saturday 31st May

With no news from the estuary the most notable records were eight Sandwich Tern and three breeding plumaged Great Northern Diver offshore and a Tawny Owl being mobbed in the Entrance Bushes. 

Other Wildlife: The day's highlight was the discovery of a Brimstone caterpillar on the site's only Alder Buckthorn, the first confirmed breeding for the Recording Area.
