We have been privileged to have a blue tit roost in a camera box for almost 2 years and 3 months. The box is left of my patio doors and a few months ago we put up a box on the opposite side and within a few weeks another blue tit started roosting. As a big fan of protecting the birds I bought another few boxes and stupidly thought if they were put up near the others it would attract more blue tits as it must be a good location. So, at the weekend we put up three more boxes, one with another camera in. Unfortunately tonight my rooster hasn’t come home and I’m really upset now that I’ve read it could be because I’ve put too many boxes up and too close together. There has been a sparrow hawk in the garden regularly and I have saw this twice in the last two days - now I’m worried, is it more likely the roosting tit has been killed by predator, died of old age, moved out because he doesn’t want neighbours or maybe, just maybe he could have moved boxes. I think I should take the other boxes down in the morning and go back to just two and see if he comes back what does everyone else think?
