There was some good hirundine passage eastwards over the island in the morning, which comprised 23 Sand Martins, 157 Swallows and 18 House Martins, whilst two Grey Wagtails and a Yellow Wagtail also flew overhead. A total of 50 Willow Warblers is the highest so far this autumn, with birds spread out all over the island, particular along the mountainside; one Sedge Warbler, three Chiffchaffs and four Goldcrests were also recorded. A Black-tailed Godwit flew south over the South End in the morning, whilst a good supporting cast of other waders included three Ringed Plovers, five Sanderlings, six Dunlins, six Whimbrels, 25 Curlews, five Redshanks, one Common Sandpiper and six Turnstones. A single Sparrowhawk and two Buzzards represented the day's only raptors.
In terms of lepidoptera, it was a great day: good totals of moths in the traps were recorded, whilst some of high butterfly counts were also made. Beginning with the latter of these, the day's totals comprised 435 Green-veined Whites, two Small Coppers, four Painted Ladies, two Small Tortoiseshells, 20 Peacocks, 33 Graylings and 56 Meadow Browns. Highlights from the moth traps included the year's first Orange Swift, a female Northern Eggar, Dotted Clay and Acleris holmiana (new for Bardsey).
