What is the rarest penguin in the world?

The yellow-eyed penguin (Megadyptes antipodes) of New Zealand is often considered the rarest penguin in the world, with a total population estimated at only about 4,000 individuals. The Galapagos penguin is similarly rare, with around 1,200 individuals. The erect-crested penguin is also extremely rare and poorly studied, with dramatic population declines observed at its only breeding sites on New Zealand's Bounty and Antipodes Islands. What makes the yellow-eyed penguin particularly vulnerable is that it does not form large colonies — pairs nest individually, spread out in forested coastal areas, making conservation efforts more challenging.
