This is a fascinating little box made to track down a bee’s nest. It’s an ingenious little design and to watch the video is to learn something new (for me anyway).
It reminds me of a trick told to me by an aborigine whereby they would attempt to track back to where particular bees were coming from -say, for instance, at a waterhole. They didn’t use a box like they have done in the video. Instead, they would tie a human hair carefully around the neck of the drinking bee . To this hair they would attach a small feather. Obviously the weight of the feather bore some responsibility for whether the bee made it back to its hive. The people would then follow this returning bee back to its home , hopefully, not very far and not over inhospitable terrain.
