A nocturnal ringing session produced 12 Storm Petrels at the North End, comprising 11 new birds ringed and one retrapped individual. Daytime passerine ringing and census at Nant yielded six Chiffchaffs, with five at Nant (including two trapped and one retrapped) and one in Withies, alongside seven Willow Warblers, split as six in Withies and one at Nant. Three Blackcaps were recorded at Nant, consisting of two newly ringed and one retrapped bird. Single Swallows, Magpies and Woodpigeons were also ringed at Nant, although the highlight was retrapping a male Sparrowhawk.
