Christina got this video of one bee kicking out another bee. Not exactly sure what the reason is. Could be she was drunk/had fermented nectar (they don’t tolerate that), or that she was from another colony and wasn’t welcome (fear of robbing resources), or they felt she was in some other way damaged and unwanted. You can also see a bunch of bees dusted with pollen from all the incoming foragers landing on top of them while coming in.
A day later, I also managed to catch a video of a wasp trying to get in to steal honey, but the guard bees chased it off.
