An orb of light came from the ground in the distance and continued toward my drone at a high rate of speed

I am hobby drone pilot that owns two such crafts and have been flying for fun and amateur video for about a year.  
On the morning I have indicated, I was flying my drone early one morning in a park very near my home and was recording as I normally do.  I shot this video at 1080P 60 FPS and did not notice the anomaly until viewing it later the same morning.  While shooting toward the sun and into the middle of town this "orb" of sorts came rushing toward my craft at a high rate of speed in a straight line but not straight at me.  
At first I thought it might be a hummingbird, but seems much too fast and if you watch it pass into the lighter sky you will see that it just disappears as if it is made of light only.  The video I will send is clipped from a larger 4 gig file and if you want the whole file I can arrange that.  I would be very interested in any thought you may have regarding this anomaly.
