I moved a dead magpie off the road a while ago. There were a bunch of magpies on the powerlines around it. I sort of placed it in order next to a tree in the nature strip. They all started squawking when I picked it up, and started warbling when I placed it. I tossed out a handful of broken up dog treats, for their wake. I think they got it.

e: I remembered before all that above, what got my attention was, they were freaking out at what turned out to be cars passing near the dead magpie on the road. I was concerned for their safety getting riled up at the cars, which is why I moved it.
