This is probably the closest video shot I’ve managed to get of the bees from inside the hive. (It zooms in and tracks along the comb around the 44-second mark.)
It’s from inside a honey super, not the hive per se. I gave most of the colonies between a half and a full medium honey super full of scraped and uncapped honey about a month ago. I’ll probably do it for now instead of topping them up with sugar syrup before winter. The honey comb is pretty much bone dry by now, but maybe the bees are hanging up around the comb because it’s been so warm that they don’t need to maintain a full cluster in the brood chamber.
