Elizabeth and Malcolm’s boxes

I know we are all really surprised by the fact that Elizabeth and Malcolm’s boxes remain empty BUT they are still getting pairs visit both boxes.  There are still nest wriggles going on , and, looking at the overview on past years , some of the nests didn’t have any eggs laid until 24th and 25th April!!  We all know how quickly these birds can build a nest if they want to - so there is still some hope lovely people   Well I truly hope so anyway.  Hoping for a surge of building over the coming week.
