Slow Motion Bee Flight from above.

I placed a camera atop the entrance of my bees' hive and focused on the upper entrance. To me, it feels a little like I'm floating above them and getting to see them swim in the air. I like to watch how they move, what their wings and bodies do, and how they maneuver. It's also fun just to see how they behave and move around this upper entrance.
Each time I look at this, I see something different and surprising. I think having everything in slow motion makes it feel like I can almost keep pace with all that these bees are doing. (Although, this is just what's happening on the outside of the hive!)
What do you notice? What do you wonder? What else could you investigate?
