I am watching flying raptors quite often, but I can not remember such action as today.
This common buzard made droppings at flight and nothing small as you can see. A just made a photo.
If you would like to make such photo intentionally, I believe it would take days of effort with no outcome.
I was lucky twice: 1/ I made the photo 2/ I was not hit
