The blue tit that's taken possession of the sparrow box has been tapping inside it for four days now. Other years they've tapped on and off and sometimes around the entrance hole but I've never heard one at it this long.
I've not seen it taking any nest material in yet either.
I've always thought the tapping was sort of "customising" the box and laying claim to it, is that correct?
