Elizabeth and Malcolm’s boxes

Bit like Ann, every time I look no-one is home  .  Do you know if it’s the great tit bring in nesting material?  That would be brilliant.  Just need blue tit to start in box 1 then .

ps just went to the playback for box 2 this morning and found the great tit just before 11:00 on the cameras timer on screen.  It did appear to be moving the material around but didn’t actually see it bring any in  .
pps And, the playback for box 1 shows a pair of blue tits inspecting the box
