Managed to check another 15 large boxes today, mostly Kestrel and a couple of Barn Owl. Of these 2 had old Jackdaw nests from which the young appeared to have fledged and one had 4 nestling Jackdaws in. 2 had Stock Dove eggs. Five were occupied by Kestrels at a variety of stages from eggs (a clutch of 4 and a clutch of 5) to tiny young (another 4 and 5) and one had 5 ringable young. So good occupancy and good sized broods.
A typical Jackdaw nest, overflowing with twigs. (PML)
