this birdbox has been raided by something in the last week; it was home to some bluetits but something has chewed its way in (the hole was fine a weeek ago); the box sits 15 feet up a smooth pine tree (no lower branches); there is mixed conifer/decisuous woodland 20 metres away; the nest contents have been ejected - no bird remains so presumably by a carnivore of some type; location south peak district, altitude 800'; could it have been a pine marten - thought to be some in the area but I have never seen one
