Yes BuzzBee noticed my bees loitering around a super that wasn't the most tight fitting due to age. Later seen bees had plugged up gaps w/ propolis.
I temporarily get orientation flight bees mixed up w/ robbers but seems robbers are more frantic & nervous & also tell tale numerous dead bees under hives can speak to the robbing situation at hand. Sometimes moving a hive to an apiary w/ less hive density will keep robbing under control, but also some hives aren't that fit to survive when survival of the fittest during times of dearth are in full swing. That's natures way.
