Monday 31st July 2017


The Clouded Yellow butterfly has only been recorded on one previous occasion so far this year, it is an immigrant originating from Southern Europe and North Africa so numbers occurring do fluctuate greatly, during a good year they can produce up to three broods.
A strong Westerly wind and cooler temperature overnight continues to influence low return on the moth traps.
Noted moving South over the reserve this morning, 9 Swallow, 8 Sand Martin, 7 Swift, 3 Willow Warbler, 1 Hobby, 1 Sparrowhawk & 1 Yellow Wagtail. Accumulating on the point coming into the high tide, 24 Common Tern plus 2 North and 4 South, 1 Sandwich Tern plus 2 North & 1 Turnstone.
Passage offshore going South, 18 Oystercatcher, 7 Redshank, 5 Dunlin, 3 Teal, 3 Tufted Duck, 2 Grey Plover, 2 Whimbrel, 1 Green Sandpiper & 1 Turnstone.

5 birds ringed: Willow Warbler 3, Blackbird 1, Dunnock 1
