No animal is more synonymous with Antarctica than the penguin.
Eight species call the Antarctic continent and its surrounding sub-Antarctic islands home. Ranging from the prestigious emperor to the crested macaroni, each features its own distinct look, behaviour and breeding ground.
Which species you'll see on your cruise depends heavily on your itinerary and the time of year you sail, since some are found only on the continent itself while others are exclusive to islands like South Georgia.
This guide walks you through every species you might encounter, when to see them at their best, and what the experience of a penguin colony is actually like once you're standing in front of one.
Types of penguins you'll see in Antarctica
Emperor penguin
Elusive and resilient, emperor penguins are known for their incredibly harrowing journeys that have inspired documentaries like March of the Penguins.
What do they look like?
Emperor penguins are the largest of all penguin species, standing around 110-130 centimetres tall and weighing up to 40 kilograms.
They're instantly recognisable by their striking black, white and pale-yellow colouring, with a distinctive golden-orange patch at the neck.
Where do they live?
Emperors live and breed on stable sea ice around the Antarctic continent, most notably in the Weddell Sea and Ross Sea, generally farther south than where most Peninsula-based expedition cruises travel. The penguins tend to walk 50 to 120 km inland to nesting areas.
How many are there?
There are an estimated 250,000 breeding pairs across around 60 known colonies, making them far less numerous than several other Antarctic species.
Are they easy to see?
Compared to other penguins, not particularly. Their remote breeding colonies mean only specialised voyages into the Weddell Sea, typically in November and early December, offer a realistic chance of a sighting. For most travellers, an emperor penguin encounter is the rarest prize of an Antarctic expedition.
Adélie penguin
Among the most common, Adélie penguins can be seen on just about any Antarctic cruise itinerary, no matter the destination.
What do they look like?
Looking dapper in natural tuxedos, Adélie penguins are a mid-sized species, standing around 70 centimetres tall and weighing just 3.5–6 kilograms. Their feather pattern is a simple black-and-white tuxedo look and they have a distinctive white ring around each eye.
Where do they live?
They breed further south than most other penguins, nesting in dense colonies along the Ross Sea coastline and scattered across points on the Antarctic Peninsula. Adélies tend to favour ice-free rocky ground that’s close to the water.
How many are there?
Adélies are one of the most numerous Antarctic species, with an estimated 2.5–5 million breeding pairs across the continent.
Are they easy to see?
Yes, especially if you’re on a Ross Sea voyage. If you’re not, you’ll still have a good chance of spotting them though as Peninsula cruises will likely visit smaller colonies. Adélies’ large numbers and predictable coastal nesting sites make them one of the more reliable sightings of the Antarctic cruising season.
Gentoo penguin
With just about guaranteed sightings, gentoos are one you’ll want to familiarise yourself with before your journey. These curious birds aren’t shy so don’t be surprised if they approach you.
What do they look like?
Gentoo penguins stand around 75–90 centimetres tall and weigh between 4.5 and 8.5 kilograms. They’re easily identified by the bright white patch above each eye and their vivid orange-red bill and feet that stand out prominently against the white snow and ice.
Where do they live?
Gentoos favour ice-free coastal areas, but nest extensively across the Antarctic Peninsula, the South Shetland Islands, and sub-Antarctic islands including South Georgia.
How many are there?
There are roughly 300,000–400,000 breeding pairs, and their numbers have actually been increasing in parts of the Peninsula in recent decades as conditions shift.
Are they easy to see?
Very. Although total populations are much smaller than other species, gentoos are among the most commonly encountered penguins on standard Peninsula itineraries. Colonies are accessible and gentoos have a curious, approachable nature that makes for excellent close-up viewing.
Chinstrap penguin
Easily identifiable, chinstrap penguins are another species commonly spotted during Antarctic cruises, especially those that visit the South Shetlands.
What do they look like?
Named for the narrow black band that runs beneath their chin like a helmet strap, chinstrap penguins stand around 68–76 centimetres tall and weigh 3–5 kilograms,
Where do they live?
They're found in large numbers across the South Shetland Islands and the Antarctic Peninsula, typically nesting on rocky, exposed slopes above the shoreline.
How many are there?
Chinstraps numbers are estimated to be around 3–4 million breeding pairs, making them one of the more abundant Antarctic penguin species, though some colonies have shown notable declines in recent years.
Are they easy to see?
Yes, especially around the South Shetlands, where large, accessible colonies make for reliable and impressive viewing, especially during the breeding season.
King Penguins, Volunteer Point, Falkland Islands
King penguin
Second in size only to emperors, king penguins can be easily spotted across the sub-Antarctic islands that sit north of the Drake Passage.
What do they look like?
The second-largest penguin species, kings stand around 90–100 centimetres tall and weigh about 11–16 kilograms. They’re distinguished by vivid orange ear patches and a sweeping orange stripe down their bill.
Where do they live?
They breed exclusively on sub-Antarctic islands rather than the continent itself, with the largest and most accessible colonies found on South Georgia Island.
How many are there?
There are about 1.6 million breeding pairs worldwide, with some South Georgia colonies alone numbering in the hundreds of thousands.
Are they easy to see?
If your itinerary includes South Georgia, then it’s extremely likely you’ll see some king penguins. Their colonies are among the largest and most spectacular wildlife gatherings anywhere on Earth.
If you do want to spot them, keep in mind king penguins are not seen on standard Peninsula-only voyages.
Macaroni penguin
Named after the fashion statement rather than the pasta shape, the macaroni penguin is a crested penguin that’s easy to identify from it’s unique feathered headdress.
What do they look like?
Best known for the flamboyant yellow-orange crest of feathers that sweep back from above each eye, macaroni penguins stand around 70 centimetres tall and weigh 3–6 kilograms.
Where do they live?
They breed on sub-Antarctic islands, including South Georgia and the South Sandwich Islands, typically nesting on steep, rocky slopes. They do go down as far south as the Antarctic Peninsula. Across the continent and its nearby islands, there are more than 200 breeding colonies.
How many are there?
While emperors and gentoos have captured much of the attention, macaronis are actually the most numerous penguin species in the world, with an estimated 9–18 million breeding pairs.
Are they easy to see?
On itineraries that include South Georgia or the South Sandwich Islands, you’ll have a good chance of seeing them on your expedition. Though their steep, rocky nesting sites can make some colonies trickier to access than gentler-sloped alternatives.
Rockhopper penguin
Actually separated into three different types, the northern, eastern and western, rockhopper penguins are also crested penguins, but not as prominently so as the macaroni.
What do they look like?
Southern rockhopper penguins are one of the smallest Antarctic-region species, standing just 45–55 centimetres tall and weighing 2–3.5 kilograms, with spiky yellow-and-black crest feathers and striking red eyes.
Where do they live?
They breed on including the Falklands and smaller islands near South Georgia. Other sub-species live on Australia and New Zealand’s sub-Antarctic islands.
Generally, rockhoppers typically rest on rocky coastal slopes — true to their name, hopping between boulders rather than waddling.
How many are there?
There are an estimated 1–1.5 million breeding pairs of southern rockhoppers, though populations have declined significantly in some areas over recent decades.
Are they easy to see?
Fairly, especially on itineraries that include the Falklands or relevant sub-Antarctic islands, where their energetic, rock-hopping behaviour makes them a real crowd-pleaser despite their smaller size.
Royal penguin
Another type of crested penguin, the royal penguin is unique in that it’s endemic to Australia’s sub-Antarctic islands.
What do they look like?
Royal penguins stand around 70 centimetres tall and weigh 3–6 kilograms, closely resembling the macaroni penguin but with a distinctive crest that looks like it’s been slicked back rather than worn like a crown, despite its royal name.
Where do they live?
They breed almost exclusively on Macquarie Island, a sub-Antarctic island administered by Australia, making them a species of particular pride and interest for Australian travellers.
How many are there?
There are an estimated 850,000 breeding pairs, nearly all concentrated on Macquarie Island, making it effectively their only breeding ground on Earth.
Are they easy to see?
Yes, if you’re in the right place. Royals will only be seen on itineraries that include Australia’s Macquarie Island, which isn't part of every Antarctic voyage. For those that do call there, the colonies are large, dense and an absolute must-see.
Royal penguins won’t be seen on itineraries to the Antarctic Peninsula.
Best time to see penguins in Antarctica
The Antarctic cruising season runs from November to March, and luckily this aligns nicely with penguin behaviour. From month to month, it shifts noticeably as the summer progresses, regardless of which species you're hoping to see.
Here’s what you can expect of penguins throughout the season:
- November marks the start of the breeding season, with penguins arriving at their colonies, pairing off, and beginning courtship displays. It’s a key time to witness the social side of colony life, and the best window for a rare emperor penguin sighting on specialised Weddell Sea voyages.
- December is peak breeding season across almost every penguin species, with most laying and incubating eggs. The first chicks begin to hatch late in the month.
- January is chick season in full swing, with fluffy grey chicks being fed and guarded closely by their parents. it’s widely considered the most rewarding month for penguin photography across the board.
- February sees chicks growing rapidly and beginning their moult into juvenile feathers, a scruffy but fascinating stage to witness, while adults make increasingly long foraging trips to keep up with demand.
- March brings the season to a close, with colonies thinning out as fledged juveniles and adults head back to sea ahead of the Antarctic winter.
King penguins are a notable exception to this rhythm. Their breeding cycle spans more than a year, so chicks in various stages, including large, brown and fluffy from the previous season, can often be seen alongside newly laid eggs regardless of when you visit.
What to know and expect when you see penguins
Seeing a penguin colony in the wild is a genuinely different experience to seeing a few in a zoo.
International Association of Antarctica Tour Operators (IAATO) guidelines require visitors to keep a minimum distance of five metres from wildlife. But, of course, penguins have absolutely no concept of this rule, so it's common for a curious penguin or two to waddle right up to you. If this happens, try not to get too excited and approach them too. It’s likely that expedition staff will ask you to calmly hold your ground..
Colonies are also far louder and more pungent than most people expect. Thousands of birds calling, squabbling and feeding chicks create a constant ruckus. The smell of a large guano-covered colony carries an unfortunately fair distance on the wind.
The scale of colonies varies enormously by species and location. A rockhopper colony might number in the hundreds, while King penguin colonies on South Georgia or royal penguin colonies on Macquarie Island can number in the tens or hundreds of thousands, making for an overwhelming sensory experience.
Some colonies, like those of the macaroni penguin, are also perched on steeper terrain, so expect a bit more of a scramble on shore to get a good vantage point.
None of this detracts from the experience though. If anything, it's part of what makes standing among a working penguin colony feel so real, and so far removed from anything you'll experience back home.
