They get everywhere! This is a picture of a bluetit looking into Box3 from
the side mounted camera. This box is also now back up again, having been
cleaned out like the others. (By the way, this year we have decided to refer
to this box as Box3 as its previous name of BBB sounded a bit odd.)
I have also taken the opportunity to raise the position of the side mounted
camera by about 10cm as the nest built by last years occupant was deeper than
I had expected and as a result we saw more nest than birds - or would have done
if the chicks had lived longer than 48 hours!
At 32mm, the hole is big enough for a sparrow, nuthatch and great tit as well
as a bluetit but until now, none of these larger birds has been interested in it.
