Feeling slightly better today I ventured out to see the Ross's Goose (records of which I believe are under review by the BOU). It was found showing distantly with c 5000 Pink-footed Geese, from the first layby east of the old Stracey Arms. Two Marsh Harriers and plenty of Golden Plover and, more surprisingly c 100 Black-tailed Godwit.
A visit to a local broad produced a number of broadland species, bringing the year list up to 102 (corrected!).
