Sometimes they go a robbin, sometimes they don't. When you do see it going full blast, it will be a shock. A couple weeks ago, I had some wet supers in the garage that I planned to put back on the colonys in my yard. Before I could, I had an accident and got a pretty good cut across my chest. Since I'm on some blood thinners, it wouldn't clot and I kept bleeding. I went in the house to clean up and decide whether I needed to see the sawbones. (I ended up in the emergency room and never got back to the bees.) Anyway, I looked out back the next day, and the air was full of bees, the hives had bees crawling all over them and wrestling in front of them. I also noticed the garage had been left open. OH OH
I walked in the garage (stung several times just getting there) and there were about a million bees in there swirling, and every one that bumped me stung. It was pretty ugly! I moved the supers out across the yard, pulled the tops off all the hives leaving them open, and went to hide in the house. The situation calmed during the day, but there were 1,000's of dead bees all over the driveway. I checked and didn't loose any queens, but very easily could have. I'm also glad my neighbors were all at work and not out working in their yards.
