probably in the wrong place and/or facing wrong directioni made a nesting box, followed the design by RSPB, 4 years later it,s still empty
good point, it,s next to a hedge that has two robin,s nests every year, a pair of bluetits come every year, have a look inside and depart, maybe they dont like the curtains , tis facing the right way according to RSPB, maybe ill put it down the other end of the garden.probably in the wrong place and/or facing wrong direction
