Marsh Harrier finally added to year list!

23rd August 2013 – overcast/rain later SE3/4
morning observations produced 200 Sandwich Tern but little else of note.
Grounded Migrants
The very slow trickle of Willow Warbler continues.
Diurnal Migration
A Marsh Harrier drifted east over the island and a few House Martin were again amongst a light Swallow passage.
Two Raven and a Merlin were the best of the rest.
The micro Eudonia angustea was new for the year.
