Bees from my skep (treatment-free) apiary swarmed and moved into this huge sweet chestnut tree. I checked in November and the bees were very active (see video). Trust they will survive the coming winter. I added a video of the feral bees flying into and from the three-hole and a picture of the apiary located at ca. 300m.
