I am seeking advice on what to do with a pair of blue tits that nested in my garden last spring. I live in a built up residential area, and I have a concrete garden/patio. We have some potted shrubs and a clematis but lots of concrete otherwise. We have houses all around us and a alley way behind our garden wall. There was an old bird box on our house when we moved in, and never really took notice of it until last spring where i watched blue tits build inside and nest there. They had 2 fledglings. It was extremely stressful for me as i know how many cats are around, and go through our garden daily (despite my various attempts to dissuade them). Our neighbours have a cat that uses our garden as a pathway to home. When the tits fledged, i woke up at 4am for 3 days to watch through the window for any cats. I literally sat there and waited, and would take it in turns with my partner. The fledglings were hopping around our garden for a few days which was very stressful and broke my heart! I hope they made it. Anyway, I decided right then and there, that by the end of the year i would take the box down so as not to go through that again next spring. We took it down in December.I now see the tits coming back and looking for it - which absolutely breaks my heart and now i am questioning my decision (we threw it in the bin too as it was so old). I see that tits stay within there territory and I feel like I now think I would almost rather them nest here so at least i can help give them the best chance for survival by watching out for cats - because will they nest around here anyway? I’m very torn on what to do, and would like some advice.
