About two months ago I was flying over my house in the late afternoon when I noticed about 12 pigeons flying in a group circling the trees about 200 yards away. I flew my drone in their direction and before I knew it they had gone to a slightly higher altitude while circling overhead of my drone. They would chase my drone and turn away and I would turn and chase them. This went on for about 2 minutes with the pigeons staying in close formation. Neither the birds nor I got in each others personal space. Apparently they got bored of that and flew away.
