After a night out trying to catch Storm Petrels, Stuart and Louis opened nets at Tŷ Pellaf, Steve Hughes opens at Cristin and Steve S went to do census of the north and west of the island. 

High tide wader roost at the Narrows was less productive than the previous day with only two Knot seen. There were 55 Curlew on Carreg yr Honwy. There were eight Redshank, eight Ringed Plovers and 47 Turnstones there too as well as four Grey Herons. A Grey Plover was heard calling as it flew along the west side of the island. Two Buzzards were seen over the Narrows.

A Mediterranean Gull was seen from Pen Cristin in the morning. There were 140 Kittlwakes off the west coast. 

The semi-resident Collared Dove flock of 12 were seen moving between the withies and Tŷ Pellaf. Wheatear numbers were slightly higher than previous day at 23, A Redstart was in the Lowlands and two Whinchats, the first of autumn, were in the North West Fields. 
Warblers were in short supply, but a Reed Warbler was seen at The Obs, there were two Grasshopper Warblers and four Sedge Warblers, two Chiffchaffs and 11 Willow Warblers

However, the day’s highlight was the first three Wrynecks of the autumn, one at the north End, one at Nant and another at Pen Cristin. The first of what we hope to be a bumper autumn.  

Wagtails were on the move with two Grey Wagtails seen. Four White Wagtails were seen too. Linnets were order of the day at the farm, with about 86 in the area, 36 were trapped and ringed, with a total of 142 across the whole island.. 

There were 33 Small Tortoiseshells 17 Common Blues and eight Painted Ladies scattered around the island, mostly on the Fleabane and Coltsfoot at Tŷ Pellaf.

The Painted Lady is a long-distance migrant, which is prone to spectacular eruptions into Britain and Ireland.

Each year, it spreads northwards from the desert fringes of North Africa, the Middle East, and central Asia, recolonising mainland Europe and reaching Britain and Ireland. In some years it is an abundant butterfly, frequenting gardens and other flowery places in late summer. - from Butterfly-Conservation.org
