It was a stunning day, with conditions more typical of what we expect of 'summer'. Clear blue skies allowed the sun to bake the island to a pleasant 22'C, whilst a very light north-westerly wind meant that the movement of migrants through the island was perhaps the best of the autumn so far.

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).

There are plenty of big, fluffy Manx Shearwater chicks in the earth burrows at the moment

There are some good numbers of Gannets feeding off the coast at the moment, with 79 seen today
