A couple, both cold bird homicides. Each time the victims were one of these bastards.
One morning I wake up to the sound of one's infuriating chirping outside the window. It doesn't stop. I get up and go to the window to swat it or something. Open the window, look down, and one of these awesome bastards is standing on top of a pinned noisy miner, and looks right up at me like, "You didn't see nothin'." I raise my hands and back away from the window, the chirping starts up again and slowly fades and stops. Turns out currawongs will often prey on smaller birds and if those smaller birds are noisy miners, I'm cool with it.
The other time was a noisy miner picking on a crow that was trying to eat. The miner keeps swopping it until the crow catches it, gets on top, and drags it over to a puddle. Same eerie audio of a noisy miner going nuts, then suddenly silence as the crow just sticks its head underwater, stays standing on it until the thing's lifeless, and goes back to eating.
