The best waders were 467 Curlews, 9 Whimbrels, 43 Black-tailed Godwits, 5 Greenshanks, 2 Common Sandpipers, 5 Ruffs and 29 Snipes (including 16 south). Little Egrets on Jackson's Marsh increased to 17. Other good birds were 2 Wheatears, a Redstart and 39 Sand Martins south. The escaped Crimson Rosella arrived back in the Field Station area.

On Tennyson Sands were 2 Spoonbills, 15 Little Egrets, 5 Greenshanks, a Spotted Redshank, 55 Black-tailed Godwits, a Common Sandpiper, a Wood Sandpiper, a Green Sandpiper, 2 Ruffs, a Little Ringed Plover, 2 Whimbrels and 16 Snipes, and on Jackson's Marsh 4 Green Sandpipers, 10 Greenshanks and 4 Black-tailed Godwits. A Marsh Harrier flew over. Around were 3 Wheatears.
Too windy for a ringing session.

August 11th: Cloudy conditions with easterly wind, in autumn. However, not much sign of eastern arrivals. The usual 2 Wheatears, a Marsh Harrier and a Willow Warbler were around. On Tennyson Sands was a Garganey, a Spotted Redshank and the usual other waders. Croftmarsh held 35 Golden Plovers. A Great Skua, an Arctic Skua, a Wood Sandpiper and 16 Snipes flew south, and a Sooty Shearwater and 8 Arctic Skuas north.
