Box3
still doesn't seems to have a pair who have settled on it as their nesting
place. Both great tits and bluetits still visit from time to time, but
no nesting material has been brought into the box, neither have we seen any
nesting wriggles.Here a bluetit comes to inspect.
A

However,
it didn't stay long.
