After one or two quite indifferent visits just lately we were very pleased to hear today from Nick Hopper that the first night of his last attempt at nocturnal sound recording - last Tuesday/Wednesday 10th/11th - coincided with some decent passage. Nick reports that the most noteworthy bird was a Moorhen; waders comprised 2 flocks of Purple Sandpipers, 7 Common Sandpiper, a Bar-tailed Godwit, at least 10 flocks of Whimbrel, 7 flocks of
Ringed Plover, 11 flocks of Dunlins and 2 Turnstones, whilst there were also 3 parties of
Arctic Tern, 4 parties of Common Tern and a Sandwich
Tern. Further noteworthy loggings included a Grey Heron, 4 Pied Flycatchers, 3 Spotted Flycatchers and 2 Tree
Pipit.
