From Rare Bird Alert in Britain:
Sunday 30th August 2015
New discoveries today included two juvenile Pallid Harriers together at Hillwell, Shetland, single Citrine Wagtails on North Ronaldsay, Orkney and at Black Hole Marsh, Devon and a Red-rumped Swallow at Dungeness RSPB, Kent.
Scarcity highlights were singles of Woodchat Shrike, Marsh Warbler, Melodious Warbler, Icterine Warbler, Ortolan Bunting, Rose-coloured Starling, Dotterel, Buff-breasted Sandpiper and Red-necked Phalarope, two each of Bluethroat, Barred Warbler and Hoopoe, three White-winged Black Terns, at least six Honey Buzzards, seven Red-backed Shrikes and 21 Wrynecks. A flock of 23 Cattle Egrets in the Avon Valley in Dorset and Hampshire is almost certainly a British record.
