I thought this was interesting on the Mavic forum.

Air 2 - Any idea what just flew past the drone?

Hi, this is a snippet from a video I caught yesterday. Any idea what just zoomed right in front of my drone at high speed?

Only Dandelion (or similar) seeds/pods floating by... no big mystery to me

I had the same experience this week flying over a recently mowed field. Same exact fuzzy dumbbell shape, rotating, zigging and zagging, flying up out of the field and past the drone. My first thought was a bird with very fast flapping wings, like a humming bird. The dumbbell shape doesn't fit well with dandelion or cottonwood fluff shapes:

You'll have to ask Cactus Jack. Weird to me.
