Single Spotted Fly & Willow Warbler briefly early on. 14 Swallow went south & a House Martin north. Otherwise it is largely down to the locals plus baby birds.
Notocelia cynosbatella is another "bird poo" micro - but one of the commoner and easier to identify.
Ringing: 2 Great Tit, 1 House Sparrow, 1 Linnet.
