A clear but overcast early morning, briefly brightening up mid-morning, before heavy fog once again set in for most of the day. Today was an undoubted improvement on the migration front however. Like other observers across the UK, we had our first strong push of Chiffchaffs today, with 26 logged. 15 Stonechats was also a noticeable increase on previous days. Other likely migrants logged today were 96 Meadow Pipits, 14 Goldcrests, five Wheatears, eight Pied Wagtails and a single White Wagtail. 

Offshore two Manx Shearwaters moved south off the South End early in the morning, while 397 Razorbills were counted, 373 of these on the East Side of the island. Otherwise small numbers of Guillemot, Kittiwake and Fulmar were logged moving back and forth. The immature Grey Heron that has been present for at least a few weeks was seen at several locations around the island, and singles of Buzzard, Peregrine and Merlin entertained, the latter swooping after Wagtails and Pipits feeding on the Wrack at Solfach. Ten Shelducks were logged today, including three pairs on the Narrows and Solfach chasing each other around. With Meadow Pipits parachuting, Choughs visiting a nest site at Pen Cristin and a Moorhen wrestling with a broken Bramble twig twice its size in the Obs Garden (presumed to be gathering nest material, as we're not sure what else it could be doing with it!), the breeding season seems to be underway, at least for some species.

Two Water Rails were again logged in the Withies, five Snipes were in the wetlands and a high tide resulted in good numbers of Waders, mostly at the Narrows and Carreg y Honwy; 147 Oystercatchers, 18 Redshanks, ten Purple Sandpipers, ten Curlews, two Turnstones and a single Whimbrel were seen in total today.

Dark Sword Grass were once again in the Obs Moth Trap in good numbers, with 14 caught today. The only other moth was a single Common Quaker. A few unidentified Bumblebees, presumed Buff-tailed (Bombus terrestris) were seen high in the newly blooming Blackthorns in the Withies.
