Today I saw one of these:
Which made me slightly suspicious, since usually when they're feeding they perch on top of the wall, or on one of the drainpipes.
Also, it is sitting in the window next to the one in which I saw Kestrel chicks last year. I haven't been checking this window. I've been checking last year's window. It seems I have missed a trick. Because today, when I saw the Kestrel sitting in this spot, I made a point of having a good old peer into the back and what did I find?
Bit embarrassing to have missed them - I mean they're not exactly inconspicuous - but DAWWWWWWWWWTHEY'RESOCUUUUTE. 2 years running. Great breeding record for the site.
