The galapagos petrel is an endangered endemic seabird with a double life: it spends almost all year far out over the Pacific, yet nests in burrows dug into the misty highland forests. Here is what it is, where it nests, and why it needs our help. If you’d rather have this built around your own dates, tell us what you have in mind — free quote within 24 hours.
Galapagos petrel at a glance
- Scientific name: Pterodroma phaeopygia
- Nesting: burrows in the humid highlands of five islands
- Life: spends most of the year far out at sea
- Diet: squid, fish and crustaceans caught at sea
- Status: Critically Endangered
- Main threats: introduced rats, cats, pigs and dogs
What is it?
The galapagos petrel (Pterodroma phaeopygia) is a medium-large seabird, dark above and white below, endemic to the islands and listed as Critically Endangered. Long-winged and built for endurance flight, it ranges far across the eastern Pacific, returning to the archipelago only to breed.
Where it nests
The galapagos petrel habitat is a surprise: not the coast, but the humid highlands. It nests on just five islands — Santa Cruz, San Cristobal, Floreana, Isabela and Santiago — digging burrows in soft forest soil well inland and uphill. Outside the breeding season it disperses over the ocean, usually staying far from land and feeding on squid, fish and crustaceans.
Slow, careful breeding
Its breeding is slow and careful. Galapagos petrel nesting happens in long burrows, where a pair raises a single chick and returns to the same site year after year. Adults visit the colonies at night to avoid predators, filling the highland darkness with their calls. Because each pair raises so few young, every lost nest hurts the population.
Why it is endangered
The petrel’s highland burrows leave it terribly exposed to introduced animals: rats, cats, pigs and dogs all raid nests for eggs and chicks, while farming has eaten into its forest habitat. Conservationists now protect colonies, control predators and monitor burrows to keep the species going. As a bonus, the petrel carries marine nutrients inland, quietly fertilising the highlands. Our 7-day island hopping trip covers this stretch.

Where to see it
It takes luck and timing:
- At sea — on inter-island crossings, watch for a fast, banking seabird far from shore.
- Highland edges at dusk — near breeding colonies on Santa Cruz and San Cristobal.
- With a guide — who knows the colony areas and the bird’s flight pattern.
Quick facts
A few more galapagos petrel facts:
- Its scientific name is Pterodroma phaeopygia; endemic and Critically Endangered.
- It nests in highland burrows on five islands.
- It spends most of its life at sea over the eastern Pacific.
- A pair raises a single chick and reuses the burrow.
- Introduced rats, cats and pigs are its main threat.
Pterodroma phaeopygia, an ocean wanderer
The scientific name pterodroma phaeopygia means “dusky-rumped wing-runner”, a fitting label for a medium-large seabird built for tireless flight over the open ocean. Dark above and white below, with long, narrow wings, it ranges far across the eastern Pacific, banking and gliding for days on end and coming to land only to breed. It is endemic to the islands and listed as Critically Endangered.
For most of the year it is a creature of the waves, feeding on squid, fish and crustaceans far from any coast. That double life — ocean wanderer for months, then highland nester for a brief season — is what makes it one of the most intriguing and least-seen of all the islands’ seabirds.
Galapagos petrel habitat and nesting
The galapagos petrel habitat holds a real surprise: it nests not on the coast but in the humid highlands, digging burrows in soft forest soil well inland and uphill. Only five islands — Santa Cruz, San Cristobal, Floreana, Isabela and Santiago — host breeding birds, and the colonies lie in the cool, misty zone far above the sea.
Galapagos petrel nesting is slow and careful. A pair raises a single chick in a long burrow and returns to the same site year after year, visiting only at night to avoid predators and filling the highland darkness with their eerie calls. Because each pair produces so few young, the loss of even a single nest is keenly felt.
Galapagos petrel facts and the fight to save it
A few galapagos petrel facts explain its plight. Its inland burrows leave it terribly exposed to introduced animals — rats, cats, pigs and dogs all raid nests for eggs and chicks — while farming has eaten into its forest habitat. Together these pressures have driven the species to the edge, and recovery is slow for a bird that breeds so cautiously.
Conservationists now protect colonies, control predators and monitor burrows to keep it going, and the work is paying off in some areas. As a bonus, the petrel carries marine nutrients inland, quietly fertilising the highlands — one more reason this ocean wanderer matters far beyond its own survival.
Most petrels nest on bare cliffs or open islets, but this one breaks the mould. It flies inland to breed, digging long burrows in the soft, moist soil of the lush highlands — sometimes hundreds of metres above the sea and far from the coast. Parents commute between the ocean, where they feed on squid and small fish far offshore, and these hidden highland nest-chambers, returning under cover of darkness to avoid predators.
That highland habit is also its greatest vulnerability. The introduced rats, cats and pigs that roam the inhabited islands raid the burrows, taking eggs, chicks and even adults, while farming has eaten into the nesting grounds. Despite numbers still in the tens of thousands of pairs, the decline has been steep enough to make it Critically Endangered, and its survival now leans heavily on burrow protection and predator control in the highlands.
At sea it is unmistakable to a trained eye: a medium-large, long-winged seabird, dark above and clean white below, with a dark cap and a bold white forehead, banking and wheeling on stiff wings over the open Pacific. It is long-lived and faithful to its birthplace, returning year after year to the same colony, which is exactly why protecting those few highland strongholds matters so much.
Frequently asked questions
Where does the galapagos petrel nest?
In burrows dug into the humid highland forests of five islands: Santa Cruz, San Cristobal, Floreana, Isabela and Santiago.
What is its scientific name?
Pterodroma phaeopygia. It is endemic to the islands and listed as Critically Endangered.
What does it eat?
Squid, fish and crustaceans, caught at sea over the eastern Pacific, where it spends most of the year.
Why is it endangered?
Introduced rats, cats, pigs and dogs raid its highland burrows, and farming has reduced its forest habitat.
Can you see it?
Sometimes — at sea on crossings, or near highland colonies at dusk on Santa Cruz and San Cristobal.
How many Galapagos petrels are left?
Numbers still run into the tens of thousands of breeding pairs, but the population has fallen so sharply — mainly because introduced rats, cats and pigs raid its highland burrows — that the species is now classed as Critically Endangered.
Meeting the ocean wanderer
The galapagos petrel ties the open ocean to the green highlands in a single life. Catch one banking over the waves, or hear one calling in the dark hills, and you are sharing a moment with one of the islands’ rarest travellers.
