Man, I wasn't even attempting to troll anyone with this. I just thought the juxtaposition of a video showing how intelligent magpies are with a video of people pointlessly killing them would be interesting. As in: here is something beautiful. And here is what we're doing to ruin that.
This video could be more complicated than it first appears. Apparently these magpies were introduced to New Zealand and are classified as pests there. Maybe this is how goat snipers practice?
