An excellent day for non-avian diversity. The most spectacular highlight was probably an Ocean Sunfish off Pen Cristin, although a BLACK-TAILED SKIMMER also at Pen Cristin, was only the second record for the island. Two male Darters were almost certainly Red-veined Darters, but were only seen in flight very briefly. It was another great day for Red Admirals, with 78 seen, and seven Silver Y's completing the immigrants. Our first Meadow Browns have also emerged in the last few days, and we saw another Emperor Dragonfly on Pwll Cain.

On the bird front, it was pretty quiet,with the exception of a thoroughly weird Coal Tit! This mostly sedentary species is uncommon at the best of times on Bardsey, and even more so in midsummer. Three juvenile Starlings were a sign of autumn, while Grey Wagtail and Collared Dove from previous days lingered.

42 Swifts moved south through the island, while a female Kestrel went strongly north through the Wetlands in the afternoon.
