O.K. So, I just watched this site for the first time
and Holy Moly, it is like watching a horror movie. One crow (jackdaw?) in the nestbox), a beautiful and extremely nervous Kestrel at the entrance and eventually attacked and replaced by another crow. Then 2 crows in the nestbox scratching around, stirrring up feathers, feathers flying, whose feathers, doves perhaps? And outside there are dove sounds and someone walking a huge dog. No end of action. No wonder people are talking about this site.
