Most of the world’s 18 penguin species actually live outside Antarctica. Penguins breed on every continent in the Southern Hemisphere, and one species even crosses the equator into the Northern Hemisphere. From the beaches of South Africa to the coasts of New Zealand and the volcanic shores of the Galápagos Islands, penguins have adapted to climates far warmer than the icy landscape most people picture.
South America’s Pacific and Atlantic Coasts
South America is home to several penguin species spread across thousands of miles of coastline. Magellanic penguins breed along the coasts of southern Argentina and Chile, with colonies numbering in the hundreds of thousands at sites like Punta Tombo in Patagonia. Every autumn, many of these birds migrate north along the Atlantic coast, sometimes reaching as far as southern Brazil.
On the Pacific side, Humboldt penguins live along the coasts of Peru and Chile. Their range extends surprisingly far north for a penguin, reaching into tropical latitudes. This is possible because of the Humboldt Current System, which pushes cool, nutrient-rich water up from the deep ocean along the coast. Sea surface temperatures in this current can be as low as 16°C even at latitudes where the open ocean sits near 25°C. That upwelling supports massive schools of small fish, giving the penguins a reliable food supply in waters that would otherwise be too warm and too unproductive to support them.
The Galápagos: Penguins at the Equator
The Galápagos penguin is the only penguin species found north of the equator. Living on the Galápagos Islands off the coast of Ecuador, these small penguins survive right on the equatorial line thanks to the same cold-water currents that feed their Humboldt relatives farther south. The population is small, typically estimated at around 1,200 to 2,000 individuals, making it one of the rarest penguin species in the world. They nest in lava rock crevices that provide shade from the tropical sun, and they feed in the cool, fish-rich waters that sweep past the western islands of the archipelago.
Africa’s Coastal Colonies
African penguins breed along the southwestern coast of South Africa and up into Namibia. They nest on rocky offshore islands and a few mainland beaches, the most famous being Boulders Beach near Cape Town, where visitors can walk within meters of nesting birds. St. Croix Island, off South Africa’s eastern cape coast, has historically been one of the largest colonies.
These penguins face serious pressure. Their population has dropped steeply over the past century due to a combination of commercial fishing, climate change, and oil spills. African penguins are specialist feeders that depend on small schooling fish like anchovies and sardines. Commercial fisheries target those same species, creating direct competition. Rising water temperatures and shifting ocean currents have also pushed fish stocks away from traditional penguin foraging grounds, leading to starvation, reduced breeding success, and lower chick survival. Severe storms and coastal flooding tied to climate change damage nesting sites as well. The species is classified as endangered.
Australia and New Zealand
New Zealand is a penguin hotspot, with more breeding species than any other country. The little penguin (called kororā in Māori) is the world’s smallest penguin, standing about 25 centimeters tall. It was once common throughout coastal New Zealand, but most populations have shifted to offshore islands where there is less disturbance from predators and humans. You can still see them on the mainland at organized viewing sites in Oamaru, Taiaroa Head, and Wellington Harbour, where banded birds have provided researchers with valuable data on their movements and lifespan.
The yellow-eyed penguin, or hoiho, is one of the rarest penguins on Earth. It breeds on New Zealand’s South Island coast and nearby subantarctic islands. The most recent count found just 143 known nests on mainland New Zealand, including Stewart Island. Without a significant turnaround, scientists predict the species could become locally extinct on the mainland within two decades. It appears on New Zealand’s five-dollar note, a symbol of national identity now in genuine danger of disappearing.
Little penguins also live across southern Australia, nesting along the coastlines of Victoria, South Australia, and parts of Western Australia. Phillip Island, near Melbourne, hosts a famous colony where thousands of birds waddle ashore each evening.
Sub-Antarctic Islands
A ring of remote, windswept islands between Antarctica and the southern continents supports enormous penguin colonies. These sub-Antarctic islands include the Falkland Islands (off Argentina), South Georgia, the Kerguelen Islands (in the southern Indian Ocean), Heard Island, Macquarie Island (south of Australia), and the Snares Islands (south of New Zealand).
Macaroni penguins have a circumpolar distribution across these islands, with a huge colony near Cape Lockyer on Heard Island, where they build nests on surprisingly steep slopes. Northern rockhopper penguins breed on seven islands or island groups scattered across the temperate Indian and South Atlantic oceans. King penguins, the second-largest species, form massive colonies on South Georgia and other sub-Antarctic islands rather than on the Antarctic continent itself. These islands sit in latitudes roughly between 46°S and 55°S, far enough from Antarctica that temperatures stay above freezing for much of the year but cold enough to support the rich marine ecosystems penguins depend on.
How Penguins Survive Warm Climates
Penguins evolved in cold water, so species living in temperate and tropical climates face a real thermoregulation challenge. They forage in cool ocean water (African penguins feed in seas between 10°C and 20°C) but breed and molt on land where air temperatures can exceed 30°C. That gap requires a set of cooling strategies their Antarctic relatives never need.
African penguins begin panting to shed heat at air temperatures as low as 22°C when nesting in direct sunlight. In shaded nests, panting kicks in later, around 29°C to 31°C, because convective airflow helps cool them passively. Beyond panting, penguins change their posture: they stand upright, raise their heads, and extend their flippers away from the body to expose less-insulated skin to the air, letting heat radiate away. Bare patches of skin around their eyes and on their faces also help dissipate warmth, functioning like built-in radiators. Beneath the surface, networks of blood vessels act as heat exchangers, shuttling warm blood from the body’s core to the skin when cooling is needed and conserving it during cold dives.
Cold ocean currents are the other half of the equation. The Humboldt Current along South America and the Benguela Current along southwestern Africa carry cold, nutrient-dense water into otherwise warm latitudes. Without these currents, penguins could not survive in Peru, Chile, or South Africa. The currents deliver both the cool water penguins need to regulate their body temperature while swimming and the dense fish populations they depend on for food. As climate change shifts these current patterns, the geographic range where non-Antarctic penguins can thrive is narrowing.
