Galápagos flightless cormorant

The only cormorant in the world that cannot fly, and one of the best arguments that evolution happens fast. Over millennia of predator-free, fish-rich coastline, the strongest swimmers out-reproduced the strongest flyers, the wings shrank, and the bird became the heaviest cormorant species. Today roughly 1,600 adults remain, endemic to Fernandina and the coasts of Isabela (galapagos.org). It is a west-island species: put it on your must list and your itinerary will follow.

Where to see them

The population splits between Fernandina and Isabela’s north and west coasts, where the cold upwelling keeps the water food-rich:

No land-based day trip reaches them: every reliable site sits on the western itineraries that only cruise boats cover. That logistics split is in our cruise vs land guide.

When to see them

Year-round, since they breed opportunistically, but most eggs are laid between May and October, and courtship is a show worth timing: pairs face each other and turn in a tight circle with their necks intertwined, a dance no other cormorant does. A clutch averages three eggs with about 35 days of incubation, and chicks stay dependent on adults for more than 70 days. El Niño is the recurring catastrophe: the 1982–83 event removed roughly half the population. Recovery is slow because a bird that gave up flight also gave up dispersal, and it can only rebuild where it already lives.

How they live

Males are about 35% heavier than females. The stubby wings are vestigial; swimming comes from the powerful legs and webbed feet, and they hunt bottom fish and octopus in regular dives to 10–15 m, with individuals recorded far deeper. On land they look prehistoric and slightly wrong, holding the wings out to dry like a flag with no wind. Adults make a low, growling call, unusual for a cormorant.

Conservation

Listed as Vulnerable, and the profile is fragile by design: one species, two islands, the smallest range of any cormorant, and total dependence on cold-water upwelling that climate cycles can switch off. Fernandina is the protective miracle: the island has never been colonized by introduced species, which is why its cormorants, penguins and marine iguanas thrive in a way no inhabited island can match. The National Park’s panga-only access rules around nests keep the human footprint small (rules here).
