I had about a dozen black vultures on the ground separating a day old calf from a momma cow. Momma cow was charging them but they kept on. I walked out and ended their terrorizing of my calf. I have no doubt that had I not noticed, that they would have eventually killed it. Black vultures on our farm are not welcome.
Also had a possum in a foot hold trap that as I was walking up to check, noticed several buzzards, both turkey and black. Then the craziest thing, a yote came in, but guess he either saw me or maybe the birds were too much. All this while I am steady walking towards them less than 200 yards away. Possum was all but dead.
