Flightless Cormorant: The Galapagos Bird That Cannot Fly

The flightless cormorant is the only cormorant on Earth that cannot fly — a seabird that traded flight for diving. There are barely 1,000 breeding pairs, all on the western islands of Fernandina and Isabela. Here is why it lost the power of flight, where to see it, and what makes this Galapagos cormorant so special.

Of all the strange evolutionary experiments in the Galapagos, the flightless cormorant might be my favourite. It is a bird that, given an island with no predators and a sea full of fish, simply stopped bothering to fly — and watching one dry its useless little wings on a black-lava shore tells you everything about how these islands work. It is one of the rarest birds on the Galapagos birds trail; the more accessible Galapagos penguin shares the same cold western waters.

Flightless Cormorant Evolution: Why Can’t It Fly?

On the cold, food-rich coasts of the western Galapagos, the ancestors of this bird had everything they needed within diving distance and no land predators to escape from. Over generations, the energy spent growing big flight muscles and wings became a waste, so evolution shrank them. Today the flightless cormorant has stubby, ragged wings less than half the size it would need to fly. This is the heart of flightless cormorant evolution: with no land predators and rich, cold upwelling right offshore, the energy spent on flight muscles was simply wasted — so natural selection shrank the wings.

What it lost in the air it gained in the water. It is a powerful swimmer with dense bones, webbed feet and a long hooked bill, diving close to shore for fish, eels and octopus. It is one of the clearest living examples of evolution you can watch in a single afternoon.

Flightless Cormorant Galapagos Islands: Where to See It

Because it cannot fly, the galapagos cormorant lives only where its food is — the cold western shores. You will not find it on the central islands. The best spots: Honestly, the flightless cormorant galapagos islands range is the catch: it lives only on Fernandina and western Isabela — the far west, which most land-based travellers only reach on a western-itinerary cruise or a long Isabela day boat, not from the main hotel islands.

• Punta Espinoza, Fernandina — the classic site; cormorants dry their wings on the lava beside marine iguanas. Fernandina is reached on cruises and some western tours.
• Isabela — Elizabeth Bay and around Puerto Villamil — the most realistic place to see one on a land-based trip.

Best time: they breed year-round and do not migrate, so any season works. Look for them perched low on the rocks with their wings half-open after a dive. This is exactly the ground we cover on our 6-day Isabela adventure tour.

Quick Flightless Cormorant Facts

A few quick flightless cormorant facts that surprise most visitors:

• Species: Nannopterum harrisi (formerly Phalacrocorax harrisi) — the only flightless cormorant in the world.
• It is endemic to the Galapagos and lives only on Fernandina and Isabela.
• There are only about 1,000 breeding pairs, making it one of the rarest seabirds anywhere.
• It has striking turquoise eyes and short, stunted wings.
• Both males and females help build the seaweed nest and raise the chicks.

Flightless Cormorant Swimming: Built to Dive, Not Fly

For the Galapagos flightless cormorant, the loss of flight is a textbook case of evolution trimming what is no longer needed. With no land predators to flee and a sea full of food right at the doorstep, wings became an expensive luxury, and over generations they shrank to ragged little paddles — barely a third of the size a bird this heavy would need to get airborne. In their place the body doubled down on diving: heavy, dense bones that kill buoyancy, thick muscular thighs, and large webbed feet set far back like a boat’s propeller. The result is clumsy on land and superb underwater. All that flightless cormorant swimming power comes from oversized legs and webbed feet that drive it down past 60 feet after fish, eels and small octopus.

Hunting happens close to home, usually within a hundred metres of shore and rarely very deep. Powered almost entirely by those big feet — the stubby wings stay folded — it jinks through rocky shallows and kelp to corner octopus, eels and bottom-hugging fish, snatching prey in a long, hooked bill. Because its plumage is not fully waterproof, it hauls out between dives and strikes the classic pose, ragged wings held out to dry in the sun and wind: an oddly endearing habit for a bird whose wings will never lift it off the ground.

A fragile foothold in the west

It lives in just one corner of the world — the cool, productive coasts of the two westernmost islands, where the cold Cromwell Current wells up and packs the shallows with food. That single narrow range is the whole reason such a strange bird can exist at all, and also its greatest weakness. Everything depends on those cold, fish-rich waters staying cold and fish-rich. The Galapagos Conservation Trust lists it as Vulnerable (IUCN); for the wider fauna see our Galapagos wildlife guide.

When an El Niño warms the sea, the food vanishes and numbers can crash within a single season, dipping to only a few hundred birds in the worst years before slowly clawing back. With perhaps a couple of thousand individuals at the best of times, all packed into one small area, it remains one of the rarest seabirds on Earth — exposed to oil spills, introduced cats and dogs, and fishing nets as much as to the swings of the ocean. Today its entire range sits inside the national park and marine reserve, closely watched.

Its family life is as unusual as its body. Pairs nest in small colonies just above the waterline, heaping up untidy mounds of seaweed and flotsam. Once the chicks are well grown and food is plentiful, the female will often simply leave — abandoning her mate to finish raising the brood while she pairs with a new male to breed again. Where food can be almost limitless for a while, that strategy lets a successful female squeeze a second brood from one good season, a rare twist shared by only a handful of birds.

For a visitor, an encounter is refreshingly easy and close. Utterly unbothered by people, one may stand and dry its wings an arm’s length from a panga, or porpoise past snorkellers without a care. That fearlessness, and the sheer improbability of a seabird that gave up the sky, make it one of the most quietly memorable creatures in the whole archipelago — a living reminder of just how far isolation can push evolution.

Frequently asked questions about the flightless cormorant

Seeing the flightless cormorant up close

The flightless cormorant is not the flashiest bird in the Galapagos, but it might be the most thought-provoking — proof, standing right in front of you, that evolution will happily undo a million years of flight if the island says it is no longer needed.

If you want a realistic shot at seeing one, the western-Isabela circuit it lives on is covered by our land-based Galapagos tours. Read more at the Charles Darwin Foundation, or meet the rest of the cast in my guide to Galapagos islands animals.
