Cuckoo's Cunning: The "Laziest" Bird's Clever Survival Strategy Revealed

• Birds are vital for Earth's ecosystem balance, with over 11,000 species globally.
• The Cuckoo is dubbed "lazy" for not building nests or raising its own young.
• Cuckoos employ "brood parasitism," laying eggs in other birds' nests, often removing a host egg.
• Cuckoo eggs mimic host eggs in appearance; the chick hatches early and pushes out other eggs/chicks.
• This behavior is a highly successful and intelligent survival strategy, not mere laziness, also seen in other species.

Why It Matters: The Cuckoo's "laziness" is a clever evolutionary strategy for survival and reproduction.
