Hi, i put up blue tit nestboxes over the winter and two seem to have prospective tennants.My only worry is that as the warmer weather approaches and my children start playing outside they will scare the birds off or prevent them returning to their nest often enough .I would hate them to abandon any eggs/chicks because of the children playing too near to the box.I feel silly that i didn't think of this when i put the boxes up but it was cold and the kids were not playing outside then.Does anyone know how much peace blue tits need,as i don't think i could keep the kids in all summer!!!
