Bardsey in September 2021 – warblers in the first week, wild weather and seabirds in the last week

The first week of September produced a run of scarce warblers, with an Icterine on 1st, a Barred on 2nd and a Blyth’s Reed on 5th. The following day (6th) produced a huge fall of warblers, with over 700 Willow Warblers and 100 Chiffchaffs on the island, including a Willow Warbler bearing a Spanish ring. If that was a spectacular start to the month, the final week produced wild weather and large seabird movements, with over 11,000 Kittiwakes on a single day and 1413 Gannets on a single day – the second highest daily total in the records. The seabird movement produced Sabine’s and Little Gulls, Black Guillemots and all four skua species.

Throughout the month there was a sizeable Linnet flock on the sunflower field, peaking at over 400 on several days. Wrynecks were in good numbers, as were Spotted Flycatchers, with 49 recorded on 2nd. Grey seals were pupping throughout and the first Snow Bunting of the autumn turned up on 27th. Although moths were not in such large numbers as earlier, a splendid Humming-bird Hawkmoth was photographed feeding on fuchsia flowers.

As well as the seals, moths and birds, a great effort was made repairing the Heliogoland trap and clearing overgrown mistnet rides – the volunteers certainly earned their Bardsey lobster suppers!
