Brood parasitism Memes

The ultimate evolutionary freeloaders! Cuckoos and cowbirds have mastered the art of outsourcing parenthood by laying eggs in other birds' nests. Why build a nest, incubate eggs, and feed hungry chicks when you can trick some unsuspecting bird into doing all the work? It's like having a full-time nanny service without paying a single seed! Natural selection really said "work smarter not harder" with these birds. Their entire reproductive strategy is basically "here's my kid, good luck, I'm going on vacation!"

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!
