23rd May

Under a much clearer sky both numbers and variety fizzled out today, with quality limited to an Osprey that passed over at Ferrybridge. Grounded migrants at the Bill included 10 Chiffchaffs, 9 Wheatears, 7 Spotted Flycatchers, 6 Turnstones, 4 Willow Warblers, 2 Reed Warblers and a Common Sandpiper, with singles of Grey Heron and Yellow Wagtail overhead along with no more than a trickle of Swifts and hirundines; wader numbers continued to increase at Ferrybridge where there were 55 Dunlin, 30 Sanderling, 15 Ringed Plovers, 7 Turnstones and a Whimbrel. Despite the unpromising offshore breeze there were still a few birds moving offshore, including 9 Sanderling, 4 Whimbrel, 2 Arctic Skuas and singles of Black-throated Diver and Great Northern Diver through off the Bill.

A few more immigrant moths trapped overnight at the Obs included 8 Diamond-back Moth, 5 Silver Y and a Rusty-dot Pearl.
