At Castle Water 2 Avocet,2 Little Ringed Plover,
1 Green Sandpiper and 3 Tree Sparrow.
Plus 29 Whimbrel feeding in nearby fields, and a Marsh Harrier over
Flat Beach Quarry and Ternery Pool attracted 240 Sandwich Tern,
33 Common Tern and 10 Little Tern.
Offshore 13 Scaup could be seen from the Sea Bank near Crittal Hide,
and I suspect these are the Birds from Castle Water.
