The best bird by far was a singing Golden Oriole at 0955.   I could not see it.   It was in the bushes at the northern limit of the sheep enclosures.   It sang only four times and that was it.   Other birds include 17 Long-tailed Tits, 3 Lesser Whitethroats, 2 Willow Warblers, 3 Reed Warblers, 5 Yellow Wagtails, 8 Corn Buntings, 2 Cuckoos, 2 Kestrels, 13 Swifts, 2 House Martins, 8 Tufted Ducks and 3 Little Egrets.
