30th July

A day spent shrouded in the fog, drifted over on the light easterly breeze; the only birds of note really were an adult Black Tern on Gretchen – presumably the same one that was last seen on the 14th, now in heavy body moult, 5 Ruff also on Gretchen and more excitingly, a pristine young Garden Warbler trapped at the Obs, our first migrant warbler of the autumn!
