This morning there were about twenty Chiffchaffs singing around the site and the first Blackcap was heard, giving a tentative song. Three Oystercatchers flew over the Deep Pit, making a lot of noise. As it warmed up, Small Sallow Mining Bees and Tawny Mining Bees were seen on the fence posts, and three Brimstones, three Comas, two Tortoiseshells and a Peacock were flying. PS.
