Near 2VP this morning, and viewed from the path over the bridges (good suggestion, as the main body of birds is not visible from the railway path), 80-90 Blackwits. After a time, we saw 40-50 head to another location further from the path, so numbers may be difficult to get accurate. No other waders seen.
4 Marsh Harriers in 2 pairs seen, 3 hobbies, 6+ Great White Egrets, 1 Bittern in flight, 8+ buzzards.
