Penguins are the poster animals of cold oceans, but they’re also famously one-hemisphere creatures. You won’t find wild penguins at the North Pole. There are no penguins in the Arctic. They live naturally in the Southern Hemisphere, from subantarctic islands up to the coasts of South America, Africa, and New Zealand, and all the way down to Antarctica.

This article looks at the Antarctic and subantarctic penguin species travellers most commonly encounter on expedition voyages. For each one, we’ll cover what it looks like, where it breeds, when you’re most likely to see it, how it behaves in colonies, what it eats, the pressures it faces, and how to watch responsibly without getting in the way of penguin life (or becoming an accidental obstacle on a penguin highway).

Adélie Penguin

Facts To keep their nests clean without leaving their eggs, Adélie penguins do not leave to defecate. Instead, they project their waste away from the nest, capable of shooting it over four feet. Early 20th-century observations of their complex sexual behaviours (homosexuality and necrophilia) were deemed "too indecent" for the public and were suppressed for 100 years until they were finally published in 2012. Early explorers noted their "fatuous" disregard for safety. They were known to waddle directly up to barking dog teams out of pure curiosity, sometimes standing just inches from a dog's nose.

The Adélie penguin (Pygoscelis adeliae) is mid-sized, brisk on its feet, and instantly recognisable once you know what to look for. Adults stand about 70 cm tall and weigh roughly 3.8–8.2 kg, with a brush-tailed silhouette created by long, stiff tail feathers that often drag and help prop them up on rocky ground. Their identification cue is the white eye ring around a black iris. Their head and throat are fully black, their belly is bright white, and their short bill is mostly hidden by facial feathers, leaving only the tip exposed.

You’ll find Adélies only in the Antarctic world, along the continent’s coast and nearby islands, including the South Shetlands and South Orkneys. They breed where rock is exposed and snow-free, because their nests are built from stones, and those stones are worth fighting over. In peak season, colonies can be densely packed and loud, with constant traffic between sea and nest. Expect behaviours like pebble stealing and tobogganing (belly-sliding across snow to save energy).

Adults arrive in late October or November, lay two eggs around mid-November, and hatch chicks in December. By January, chicks gather into crèches while parents rotate foraging trips. Most fledge by February and head back to sea. After breeding, adults moult on ice where they can’t feed, which is one reason late-season access gets patchier.

Their menu is mostly krill and small fish like Antarctic silverfish, which makes them a useful indicator of changes in the marine food web. They’re listed as Least Concern overall, but some Peninsula populations have fallen sharply as sea ice declines. Adélies can project from the nest with impressive accuracy.

Chinstrap Penguin

Facts These penguins are masters of the microsleep, taking over 10,000 four-second naps a day. This allows them to accumulate 11 hours of rest while remaining constantly vigilant against predators. Unlike many penguin species that preferentially feed the stronger chick, chinstraps are known to nurture both of their two chicks equally throughout the summer. A male pair at the Central Park Zoo, Roy and Silo, famously raised a chick together, which inspired the popular children's book And Tango Makes Three.

At 68–76 cm tall and roughly 3.2–5.3 kg, the chinstrap (Pygoscelis antarcticus) is a mid-sized penguin with an upright stance, short legs, and a long, black tail that helps with balance on steep ground. Their identification mark is a thin black line running ear-to-ear under the chin, like a helmet strap. They have a clean white face and throat, reddish-brown eyes, and pink-to-orange webbed feet.

You’re most likely to see chinstraps around the Antarctic Peninsula and the South Atlantic islands, especially the South Shetlands and South Orkneys, with South Georgia hosting major numbers too. Common visitor hotspots include Deception Island, Orne Harbour, and Elephant Island. They’re near-shore feeders during the breeding season, which is handy for wildlife watching because they tend to commute between the colony and nearby water rather than disappearing deep into pack ice. In winter they head north of the pack-ice zone into open ocean.

Adults arrive October to November, lay two eggs in late November, hatch late December to early January, and by January you’ll see chicks in crèches. Fledging runs February into March, after which colonies thin out fast. They toboggan on their bellies, pursuit-dive after prey, and have a reputation for being the most short-tempered penguin in the neighbourhood.

Their diet is mostly Antarctic krill with some fish, shrimp, and squid. They’re classed as Least Concern, but many populations are declining, largely tied to reduced krill availability as conditions change. They rack up more than 10,000 microsleeps a day (four seconds at a time) to stay rested and alert.

Emperor Penguin

Facts If a mother is late returning with food, the father can secrete a nutritious curd-like substance from his oesophagus to sustain the chick. This rare trait is shared only with pigeons and flamingos. They are the deepest-diving birds on Earth, reaching recorded depths of 564–565 meters (over 1,850 ft) and staying submerged for up to 32 minutes. To survive -50°C temperatures, they form massive huddles where they constantly circulate. Birds on the cold outer edge peel off to join the warm leeward side, ensuring every individual gets a turn in the centre.

The emperor penguin (Aptenodytes forsteri) is the one that makes every other penguin look like it’s still in junior footy. Adults stand roughly 110–120 cm tall and can weigh anywhere from 22 to 45 kg, depending on the season and how long they’ve been fasting. They have a torpedo body, stiff flippers, and a posture that looks slightly overqualified for walking. In the field, look for the black head, back, and flippers, with a bright white belly, plus the yellow ear patches and pale-yellow wash across the upper breast. Their bill is long (about 8 cm) with a black upper mandible and a lower mandible that can appear pink, orange, or lilac.

You’ll only see emperors in Antarctica. They breed around the coastline between roughly 66° and 77° south, with about 66 known colonies. Famous sites include Cape Washington, Coulman Island, Halley Bay, and Snow Hill Island, the northernmost breeding population. Their non-negotiable requirement is fast ice (sea ice attached to land or an ice shelf) because they raise young on the frozen ocean itself.

Adults arrive March–April, lay a single egg in May or June, and the male incubates it through the Antarctic winter for 65–75 days. Chicks hatch in July or August, form crèches by September–October, and fledge December–January. October and November are prime for big chicks, while December and January are ideal to catch fledglings heading seaward. They survive by huddling in rotating turtle formations, and they’re notably non-territorial, an essential trait when you need to share body heat with hundreds of neighbours.

They eat mostly Antarctic silverfish, plus krill and squid, and sit high in the Southern Ocean food chain. Conservation status is Near Threatened, with sea-ice loss the main problem because early break-up can mean total breeding failure. Emperors are the deepest-diving birds on Earth, reaching around 565 metres, and can stay down for nearly 32 minutes.

Gentoo Penguin

Facts The gentoo is the fastest swimming penguin in the world, capable of reaching underwater speeds of up to 36 km/h (22 mph). Because of their speed, the Gentoo Linux operating system chose the species as its namesake to highlight its high-performance goals. Stones are so highly prized for nest-building that a male can win the favours of a female by presenting her with a particularly nice pebble.

The gentoo (Pygoscelis papua) is the third-largest penguin species, standing roughly 70–90 cm tall and weighing about 5–8 kg, often heaviest just before the annual moult. In silhouette, gentoos are easy to pick out because their unusually prominent tails swing side to side as they waddle, like a caffeinated metronome. Their identification marks are a broad white stripe running from eye to eye across the top of the head like a bonnet, paired with a bright orange-red bill and pale pinkish to orange feet.

Gentoos breed across a wide sub-Antarctic and Antarctic Peninsula range, with major colonies in the Falkland Islands, South Georgia, and the Kerguelen Islands. Popular visitor sites include Saunders Island and Carcass Island in the Falklands, Petermann Island, and Brown Bluff on the Tabarin Peninsula. Unlike many penguins, gentoos often stay near their breeding islands year-round, favouring ice-free ground and nesting on beaches or among tussock grass.

Breeding timing varies by location, but many colonies begin between September and October. They usually lay two eggs in a stone nest, hatch after 34–37 days, form chick crèches at roughly 26–30 days, and fledge at 80–100 days. December and January are good months to observe nests and small chicks, while February and March often bring larger chicks, fledglings, and adults gearing up to moult. During the moult, adults remain ashore for three to four weeks because they can’t forage without functional feathers.

Gentoos build penguin highways, packed, well-used routes between colony and sea, and they’re obsessive stone collectors. Expect noisy disputes, lunges, and outright pebble theft as they defend those circular nests. They eat opportunistically, switching between fish, krill, shrimp, and squid as conditions change, and they’re famously fast underwater, clocked at up to about 36 km/h.

King Penguin

Facts A king penguin named Sir Nils Olav resides at the Edinburgh Zoo and holds the official title of Colonel-in-Chief of the Royal Norwegian Guard. They have the longest breeding cycle of any penguin (14–16 months), meaning their colonies are occupied by chicks and adults all year round. King chicks are covered in such thick, dark brown down that early explorers once thought they were a separate species of woolly penguin.

The king penguin (Aptenodytes patagonicus) is tall, sleek, and built for long days at sea. As the second-largest penguin species, adults stand about 70–100 cm and look noticeably slimmer and more tapered than the bulkier emperor penguin. Their giveaway markings are the solid, bright orange cheek patches on either side of the head and run down in a thin line toward the upper chest. Their back is a grizzled sooty grey, and the lower mandible carries orange colour along the sides.

You’re most likely to see king penguins on subantarctic islands between roughly 45° and 55° south, such as South Georgia, the Falkland Islands, the Crozet and Kerguelen Islands, and Macquarie Island. They favour level, snow-free ground near the water, beaches, valleys, and moraines where they can shuffle between colony and surf without negotiating steep ice. Some of the best-known colonies are in South Georgia, including Salisbury Plain, St. Andrew’s Bay, and Fortuna Bay, as well as Lusitania Bay on Macquarie.

Adults arrive and go through a prenuptial moult from September to November, and egg-laying can run from November into April. They lay a single egg, balanced on their feet under a brood pouch, and incubation lasts about 54–55 days. After a 30–40-day guard phase, chicks form crèches, and fledging doesn’t happen until late spring or early summer of the following year, up to 16 months for one chick. Because that cycle overlaps, colonies can be busy year-round, with November and December often ideal to witness courtship and spot fresh eggs.

Kings eat mostly small lanternfish, plus squid and krill. They’re also serious divers, with a recorded depth of around 343 metres. On land, they’re surprisingly civil for such dense colonies. Spacing is tight, but outright brawls are uncommon because they have a firm respect for pecking distance.

Macaroni Penguin

Facts They deliberately swallow small stones, which scientists believe helps grind up the tough shells of the crustaceans that make up the bulk of their diet. Their name was coined by 19th-century sailors because their flamboyant golden crests resembled the macaroni hairstyle popular in London at the time. They are the top consumers of marine resources among all seabirds, eating an incredible 9.2 million tonnes of krill every year.

The macaroni penguin (Eudyptes chrysolophus) has a bright, golden-yellow crest swept back from the centre of its forehead toward the nape. Adults stand around 70 cm tall and usually weigh 4–7 kg. They have a black face, chin, and throat set against white underparts, plus a chunky orange-brown bill and red irises that can make them look permanently alert.

You’ll find macaroni penguins across the subantarctic and up toward the Antarctic Peninsula, breeding on islands including South Georgia, the Falklands, the South Orkneys, Kerguelen, and Heard Island. In summer, they nest on rocky ground and steep slopes, sometimes among tussock grass. Then they vanish into the open ocean for about six months, living a thoroughly pelagic life.

Adults arrive in late October and lay in early November. They lay two eggs, but the second is larger and is usually the only one that survives to hatch. Chicks hatch in mid-December, form crèches in early January, and fledge from February to March. Late summer also brings the annual moult, when adults are stuck ashore for 3–4 weeks and cannot feed at sea.

Macaroni colonies can be loud, dense, and confrontational. Expect porpoising at sea, and on land, the ecstatic display of bowing, throbbing call followed by an upright, braying finish. They eat mostly krill, plus fish and squid, and are among the Southern Ocean’s biggest wildlife consumers of krill. Their IUCN status is Vulnerable, with declines linked to climate-driven shifts in krill and competition with fisheries.

Rockhopper Penguin

Facts Due to their steep, rocky habitats, they cannot slide on their bellies like other penguins. Instead, they hop with both feet to navigate cliffs. Each of the three rockhopper subspecies is parasitised by a different, host-specific species of lice, which helps scientists track their distinct lineages. They have a strong presence in film, notably portrayed by Cody Maverick in Surf's Up and the love guru Lovelace in Happy Feet.

Rockhopper penguins stand roughly 45–55 cm tall and weigh about 2.2–4.3 kg, with a compact, upright posture and a reputation for getting around by hopping from rock to rock rather than belly-sliding like their larger cousins. They have red eyes, an orange-brown bill, and a thin yellow line above the eye that flares into spiky yellow-and-black crest feathers at the back of the head. Eastern rockhoppers (Eudyptes (chrysocome) filholi) are noted for pink edging along the bill.

Rockhoppers breed on subantarctic islands scattered through the Southern Atlantic, Indian, and Pacific Oceans. You’ll see them in places like the Falkland Islands, a stronghold for southern rockhoppers (Eudyptes (chrysocome) chrysocome), plus islands south of New Zealand such as Campbell and Antipodes, and also Heard and Macquarie. They favour rocky shorelines and steep coastal slopes, often nesting in tussock grass above the surf. Outside the breeding season, they spend months at sea in a pelagic life.

Adults arrive in October, lay in early November (usually two eggs a few days apart), and hatch chicks in December. By January, chicks form crèches, and most fledge around February, at roughly 65 days old. Adults return around April to moult, then head back out to sea through winter.

At the colony, it’s dense, noisy, and busy. Courtship includes an ascending, rhythmic song, while parent–chick contact calls are sharper and more urgent. They feed on krill and other small crustaceans, plus fish and squid, which makes them sensitive to shifts in local ocean temperatures and prey distribution. Many populations are Vulnerable, while the northern rockhopper (Eudyptes (chrysocome) moseleyi) is Endangered, pressured by warming seas, fishing competition, oil spills, and invasive species such as mice.

Royal Penguin

Facts Mothers almost always abandon their first egg just a day before laying a second, larger egg, focusing all their energy on the one with the best survival chance. To avoid fighting over food, neighbouring colonies sector off specific areas of the ocean for hunting, nearly eliminating resource competition. They are endemic to only one tiny region but form massive societies. The Hurd Point colony on Macquarie Island contains approximately half a million breeding pairs.

Royal penguins (Eudyptes schlegeli) are mid-sized, bold-looking, and famously fussy about their calendar. Adults stand around 65–76 cm tall and weigh roughly 4.2–6.3 kg at the start of the breeding season. They’re up to 20% larger than their close cousin, the macaroni penguin. Royals have a white to pale grey face and chin, plus bright yellow head plumes that meet on the forehead. Those crests take a few years to fully come in, so younger birds can look slightly under-dressed.

They are endemic to subantarctic Macquarie Island and the nearby Bishop and Clerk Islets. Hurd Point hosts an enormous colony on the order of half a million pairs, with other big concentrations around places like Nuggets Creek. They nest on beaches and bare slope patches among vegetation or tussock, then head offshore to forage in deep ocean waters to the southeast.

Males arrive in late September, females in early October, eggs are laid mid- to late October, and chicks hatch in late November to early December. By late December and through January, chicks gather into crèches, and most fledge by late February. March and April are the best months to see adults ashore for the annual moult. From roughly May to September, they’re largely away at sea.

They feed mainly on krill, lanternfish, and squid. Because they forage over very deep ocean basins (around 4,000–5,000 m), they’re an important player in the pelagic food web around their isolated home.

Conservation status is listed as Least Concern, but their presence on just a few islands makes them inherently vulnerable to problems like food competition from fishing, marine pollution and plastics, and the legacy of introduced predators such as rats. Historically, the species also faced intense hunting for oil from the late 1800s into the early 1900s.

Responsible Penguin Viewing Tips

Do

• Keep your distance, even when you feel far enough. Use binoculars or a zoom lens, and stay well back from colonies, crèches, and lone birds. Aircraft should keep wide buffers. Emperor chicks show heightened stress when helicopters come within about 1,000 m.
• Leave penguin highways open. Treat the worn tracks between colony and sea like a one-lane road. Step aside early, and let birds commute without detours.
• Follow site rules without improvising. Permits, marked routes, group size limits, and time caps exist for a reason. In many Antarctic and subantarctic sites, access is tightly managed to reduce disturbance and disease risk.
• Back away if penguins approach you. Curiosity is common in species like Adélies. The responsibility is on you to increase distance, not on the penguin to learn manners.
• Choose low-impact observation when possible. Prefer platforms and practices that minimise close approach, handling, flash, and repeated visits. If monitoring is involved, support non-invasive methods over direct contact.
• Move calmly and predictably. Slow steps, low voices, and no sudden direction changes reduce startle responses, especially near nesting areas.
• Check your boots and gear. Clean footwear and equipment before and after landings to reduce the chance of moving seeds, mud, or pathogens between sites.

Don’t

• Don’t flush adults off nests. If a bird stands up, vocalises sharply, or retreats, you’re too close. When adults leave nests, opportunistic predators such as skuas and giant petrels can take eggs or chicks quickly.
• Don’t block the route to the water. Parents may be fasting or mid-commute. Delays can cause missed feeds, longer exposure, and unnecessary energy burn.
• Don’t crowd the colony edge for photos. “Just one more step” adds up when everyone does it. Edge pressure can push birds off preferred paths and into conflict.
• Don’t touch, feed, or help. Handling increases stress and disease risk. Feeding changes behaviour and can put birds in danger around humans.
• Don’t leave anything behind, especially plastic. Litter and microplastics persist, travel, and end up in food webs. Pack out everything, including tissues and snack tabs.
• Don’t disrupt synchronised breeding cycles. With highly synchronised breeders (such as royal penguins), disturbance in one pocket can ripple through adjacent nests and crèches.
