The Wheatears numbered at least 208, with up to 70 counted in one single scan of the Narrows! The bulk of the rest of passage consisted of 152 Swallows moving through, and 92 Willow Warblers and 45 Chiffchaffs in the bushes.
However, superceding that by far was a stunning, second-year male Pallas's Warbler caught and ringed in the Observatory garden! While this is the 21st record for Bardsey, all previous records have been in Autumn from October to December, a spring record being rather extraordinary! Though perhaps more eastern fare could be expected over the coming weeks, given the record-breaking arrival of many species into Western Europe last autumn. We certainly wouldn't turn down a Siberian Accentor on return migration! The Pallas's Warbler was resighted by three observers in Plas Withy late in the afternoon.
The more routine fare was also excellent for both numbers and diversity. The sea offered probably the quietest birding, but six Sandwich Tern, a Black-headed Gull and four Puffin rewarded keen-eyed observers. The most notable wader passage of the season so far featured 34 Whimbrels, 15 Purple Sandpipers, two Ringed Plovers, two Snipes and singles of Lapwing and Dunlin, while a Water Rail in the Withies was the first for several weeks.
Overhead 32 Sand Martins and 12 House Martins moved through, plus the first Grey Wagtail in several weeks, three Rooks and some of the 15 Lesser Redpolls seen today, others also being grounded. 13 White Wagtails were in Solfach, and there was a good selection of other grounded migrants across the island; totals were 13 Blackcaps, 11 Goldcrests, four Reed Buntings and singles of Tree Pipit, Grasshopper Warbler, Sedge Warbler and Blue Tit.
