With strong westerly winds persisting throughout the day, a small amount of seabird passage included a total of 1026 Manx Shearwaters, along with 24 Fulmars, 33 Gannets, one Common Gull, 16 Guillemots, 65 Razorbills and three Puffins. There was a continued movement of swifts and hirundines over the island throughout the day, with some three Swifts, three Sand Martins, 215 Swallows and 33 House Martins. Few migrants had actually made landfall on the island, with less than five each of Chiffchaff and Willow Warbler;  however, the first Spotted Flycatcher of the year was trapped in the observatory Heligoland trap, and a Reed Warbler remained in Cristin Withy.

This smart Spotted Flycatcher was trapped at Cristin mid-morning, which is five days later than when this species arrived on Bardsey last year. We have now recorded all of our usual passing migrants, although species such as Wood Warbler (not quite annual) could still turn up 
Cydia ulicetana. This small but inconspicuous species feeds on gorse as a larvae, and the imagos are currently emerging in higher and higher numbers. A total of 30 were seen on just a handful of gorse bushes on the mountain this afternoon, and so there are likely to be thousands around the island
