A heavily overcast sky and scarcely a breath of breeze were welcome conditions as dawn broke and it was soon apparent that there was a considerable improvement in migrant numbers, with 50 Sedge Warblers, 30 Willow Warblers, 9 Tree Pipits, 2 Reed Warblers, a Grasshopper Warbler and a Garden Warbler among the grounded selection at the Bill; the dearth of a variety of other usually routine fare such as Wheatears - just 2 were logged at the Bill and another 7 at Ferrybridge - and either of the commoner flycatchers - of which there were none - did however remain entirely baffling. Overhead passage was scarcely a feature until late in the day when upwards of 100 Swifts and 50 Sand Martins appeared over the Bill; earlier the first Hobby of the season had passed through at Ferrybridge. A steady trickle of departing Lesser Black-backed Gulls, 11 Balearic Shearwaters, 2 Yellow-legged Gulls, 2 Arctic Skuas and a single Great Skua provided interest offshore; of potentially much greater interest there was what looked to be a strong candidate for an immature booby sp passing by in loose association with some Gannets - although seen quite well for the short time it was in view it showed no signs of lingering and was quickly lost heading west.
