Brood parasitism at its finest! Baby cuckoos are nature's tiny assassins, programmed with one directive: evict all nest-mates. These 10-second-old hatchlings have zero self-awareness but possess the evolutionary imperative to heave other eggs/chicks over the edge with a specialized back depression. They're literally born with murder-hardware while the poor host birds feed this imposter, completely unaware they're raising a serial killer who yeeted their actual children into oblivion. Nature's most metal biological hack!
