With their bright bills, black-and-white feathers, and slightly comical walk, puffins look almost too charming to be real. But behind that colorful appearance is a remarkably well-adapted seabird built for a life spent diving, fishing, flying, and surviving on the open ocean.
There are three living species of puffin: the Atlantic puffin, horned puffin, and tufted puffin. The Atlantic puffin is the species most familiar across the North Atlantic, nesting in places including Iceland, Norway, Greenland, eastern Canada, the United Kingdom, and coastal Maine.
Puffins spend much more of their lives at sea than on land, returning to rocky islands and coastal cliffs primarily for the breeding season. From their disappearing seasonal colors to their extraordinary fishing skills, these little seabirds have plenty of surprises.
🐧 1. Puffins Aren’t Penguins
Their upright posture, black-and-white plumage, and talent for underwater swimming can make puffins look like miniature penguins, but the two aren’t closely related.
Puffins belong to the auk family, Alcidae, along with murres, guillemots, and razorbills. Unlike penguins, puffins can fly.
And they certainly work hard at it. Their relatively short wings are excellent for underwater propulsion but require rapid wingbeats to keep a puffin airborne. The same compact body that makes a puffin look slightly awkward on land turns it into an efficient hunter beneath the waves.
🌈 2. Their Famous Colorful Beaks Are Seasonal
The Atlantic puffin’s spectacular breeding-season bill is one of its defining features, with bright shades of orange, yellow, and blue-gray.
It doesn’t look that way throughout the entire year.
After the breeding season, Atlantic puffins shed the colorful outer plates of their bills. Their faces also become grayer, leaving them with a much more subdued winter appearance.
When breeding season approaches again, the brighter facial features and bill colors return.
That means the classic brightly colored puffin pictured on postcards and calendars is essentially wearing its breeding-season finery.
✨ 3. Puffin Bills Have a Hidden Glow
A puffin’s bill is even more remarkable than it appears to human eyes.
Researchers have found that parts of the Atlantic puffin’s colorful bill fluoresce under ultraviolet light. Because birds can perceive wavelengths humans cannot, this raises intriguing questions about what puffins may see when they look at one another.
Scientists are still investigating exactly what role this characteristic plays, but it is another reminder that bird coloration can be more complicated than what we perceive with human vision.
🐟 4. Puffins Can Carry Several Fish at Once
One of the most delightful puffin sights is a bird returning to its colony with a row of tiny fish arranged crosswise in its bill.
Instead of having to swallow each fish before catching another, a puffin can continue fishing while holding previous catches in place. Backward-pointing structures inside its mouth help keep slippery prey secure while the bird catches additional fish.
Atlantic puffins eat small fish such as sand lance, capelin, herring, sprat, hake, and young cod, although their diet varies by season and location.
During nesting season, those mouthfuls of fish become especially important because adult puffins repeatedly return to the colony to feed their growing chick.
🌊 5. Puffins “Fly” Underwater
Watch a puffin swimming underwater and it becomes easy to understand why its body is shaped the way it is.
Rather than propelling itself mainly with its feet, a puffin uses its wings underwater almost as though it were flying through the sea. Its feet help with steering while its powerful wings push it toward small fish.
Atlantic puffins can dive to impressive depths — roughly 200 feet in some cases — although much of their feeding takes place closer to the surface.
Their ability to function in both air and water comes with a tradeoff. A long-winged soaring bird might fly more efficiently, but it couldn’t pursue fish underwater the way a puffin can.
🐣 6. Baby Puffins Are Called Pufflings
Few baby-animal names are as delightful as puffling.
Atlantic puffins generally lay just one egg during a breeding attempt. Both parents participate in incubation and later bring fish to the chick.
The puffling remains protected inside its nest for several weeks while it grows. When it is finally ready to leave, it typically emerges and heads toward the sea.
From that point, a young puffin begins the predominantly ocean-going stage of its life.
🏡 7. Puffins Raise Their Chicks in Burrows
Unlike seabirds that lay eggs on exposed cliff ledges, Atlantic puffins usually nest inside burrows or protected rocky crevices.
On grassy islands, a pair may dig into the soil using its bill and feet. The nesting chamber may be lined with materials such as grass, feathers, and twigs.
Burrows offer the egg and developing chick some protection from harsh weather and aerial predators. Puffin pairs may also return to the same nesting area — and sometimes the same burrow — in subsequent breeding seasons.
This creates entire puffin neighborhoods on suitable islands, with burrow entrances dotting grassy slopes above the sea.
💕 8. Puffin Couples May Reunite for Multiple Seasons
Puffins can form long-lasting pair bonds, with established pairs often returning to breed together again.
One of their most charming behaviors is sometimes called billing. A pair touches or rubs its bills together in a rapid display that can attract the attention of nearby puffins.
Much of a puffin’s life away from its breeding colony remains less visible to us. Once nesting season ends, the birds head back to sea, where studying their relationships and behavior becomes considerably more difficult.
The following spring, adults return to their breeding grounds and the noisy colony comes back to life.
🌊 9. Puffins Spend Most of the Year at Sea
Seeing thousands of puffins gathered on a coastal island can create the impression that these are primarily shorebirds.
For most of the year, the opposite is true.
Atlantic puffins spend the nonbreeding season on the open ocean, often far from land. They feed, rest, and endure winter weather at sea before returning to colonies in spring and summer.
This ocean-going lifestyle is one reason puffins can be difficult to see outside their breeding season. For birdwatchers hoping to encounter them from land or on coastal boat trips, summer nesting colonies usually provide the best opportunities.
Their months at sea also make puffins vulnerable to changes occurring throughout the marine ecosystem, even when their nesting islands themselves remain protected.
🌎 10. Puffins Face a Changing Ocean
Puffins have survived harsh North Atlantic conditions for generations, but modern populations face a combination of challenges.
Historically, hunting and egg collecting severely reduced puffin numbers in some areas. Introduced predators such as rats can also cause serious problems on nesting islands.
Today, changes in ocean conditions are an additional concern. Puffins depend on abundant small fish to feed themselves and their chicks. When warming waters alter where those fish live or which species are available near breeding colonies, adult birds may have greater difficulty finding suitable food for their young.
The story is not entirely discouraging. Conservationists have demonstrated that carefully planned seabird restoration can work.
Beginning in the 1970s, Project Puffin helped restore Atlantic puffins to Eastern Egg Rock off the coast of Maine by relocating young puffins and later using techniques such as puffin decoys and recorded colony sounds. In 1981, puffins successfully nested there again after an absence of roughly a century.
It became an influential example of how conservationists can help restore seabirds to former nesting colonies.
🗺️ Where Do Puffins Live?
The three puffin species occupy different parts of the Northern Hemisphere.
Atlantic puffins live around the North Atlantic, including parts of North America and northern Europe. Iceland is particularly famous for its enormous puffin colonies, while Maine marks the southern edge of the species’ regular breeding range in the United States.
Horned puffins live across northern Pacific waters and breed in areas including Alaska and northeastern Asia. Tufted puffins are another North Pacific species, ranging from parts of California north through Alaska and across to Asia.
All three are seabirds adapted to cold or relatively cool northern oceans.
👀 How to Watch Puffins Responsibly
Seeing puffins in the wild can be unforgettable, but nesting colonies are sensitive places.
Burrows can be surprisingly difficult to see from above and may collapse if someone walks over them. Visitors should stay on designated paths and viewing areas, follow local wildlife regulations, and avoid approaching nesting birds for photographs.
Boat tours can offer excellent opportunities to watch puffins carrying fish, gathering on the water, or flying between feeding grounds and nesting islands without entering the colonies themselves.
Binoculars and a telephoto lens provide a much better approach than trying to get physically close.
Giving puffins space isn’t just considerate birdwatching. It helps parents concentrate on the demanding job of raising their single chick.
❤️ Why Puffins Are Worth Protecting
It is easy to become interested in puffins because of their appearance. Few birds combine such an expressive face, oversized colorful bill, waddling walk, and improbable ability to carry a row of fish at once.
But puffins also connect two very different worlds.
For a few months, they are highly visible residents of crowded cliffs and grassy islands. Then they disappear onto an enormous ocean, where they spend most of the year beyond our sight.
Protecting puffins therefore requires more than safeguarding the tiny islands where we watch them. Their future is connected to healthy fish populations, clean seas, predator-free nesting areas, and functioning marine ecosystems.
The colorful beak might be what first gets our attention. The extraordinary life behind it gives us plenty of reasons to keep watching.
