Wisdom the Albatross: The World's Oldest Known Wild Bird Is Still Laying Eggs at 75

Every November, millions of seabirds return to Midway Atoll in the middle of the Pacific Ocean. Among them is one very special traveler: Wisdom, a female Laysan albatross known by the band number Z333.

Wisdom is the oldest known banded wild bird in the world. She was already an adult when a biologist first placed a band on her leg in 1956. Today, she is roughly 75 years old, and she is still returning to the island, finding a mate, laying eggs and continuing a family line that now reaches into a fourth generation.

Her story is one of the most amazing animal facts ever recorded. It is also a story about patience, survival, family and the value of protecting wild places.

A young adult bird with a very long future

Wisdom’s life was first documented on December 10, 1956, when USGS biologist Chandler Robbins banded her at Midway Atoll.

She was already sitting on a nest at the time. Laysan albatrosses usually do not begin breeding until they are at least five years old, so Wisdom was probably born around 1951 or earlier. That makes her approximately 75 years old in 2026.

Robbins gave her the name “Wisdom.” Her original metal band eventually needed to be replaced, as saltwater and time can wear down the bands worn by seabirds. But her identity remained connected to her famous number: Z333.

For decades, nobody knew that the bird Robbins had banded was still alive. Then, in 2002, Robbins returned to Midway Atoll and discovered that one of the old birds he had studied was still nesting. It was Wisdom.

The reunion was remarkable. Forty-six years had passed since he first saw her, and she was still returning to the same island to raise another chick.

The long journey of a Laysan albatross

Wisdom belongs to a species built for life over the open ocean. Laysan albatrosses, known as mōlī in Hawaiian, have long wings and a remarkable ability to glide across the Pacific while using very little energy.

Their wingspan can reach about six feet. They feed on small fish, squid, fish eggs and crustaceans. After fledging, young albatrosses may spend several years at sea before returning to land to breed.

Wisdom has spent most of her life moving between the ocean and Midway Atoll, which lies within the Papahānaumokuākea Marine National Monument. Scientists estimate that she may have flown more than 3 million miles, or about 4.8 million kilometres, during her lifetime. That figure is an estimate based on her age, migration patterns and the typical movements of Laysan albatrosses, not a precise measurement of every mile she has travelled.

Still, it gives a sense of her life. Wisdom has likely crossed the Pacific many times over, following the winds and currents that help albatrosses travel enormous distances.

Love, courtship and one egg at a time

Laysan albatrosses are famous for their elaborate courtship dances. Pairs bow, point their bills, stretch their wings, call to each other and perform a series of movements that help them recognize and bond with one another.

Once paired, albatrosses often return to the same nesting area year after year. They lay only one egg per breeding season, and both parents take turns incubating it. One bird stays with the egg while the other flies out to sea to feed.

Wisdom’s long-time mate was a male named Akeakamai. The two were seen together for many years, returning to Midway Atoll to nest and raise their young.

Akeakamai eventually stopped returning to the colony, as older birds sometimes do. That could have marked the end of Wisdom’s breeding story, but Wisdom surprised observers again. She was seen courting and later pairing with a newer male, identified by his band as EX25.

In late 2024-often described as December in news reports: Wisdom laid another egg at about age 74. The egg hatched in January 2025, making her the oldest known wild bird to hatch a chick. The chick did not survive to fledge, a reminder that even an experienced parent cannot control every danger faced by a young seabird.

A lifetime of chicks

Wisdom’s reproductive record is extraordinary because Laysan albatrosses reproduce slowly. One egg per year may not sound like much, but over several decades it adds up.

Biologists estimate that Wisdom has laid somewhere between 50 and 60 eggs during her lifetime. Estimates of the number of chicks she successfully raised or fledged vary, but commonly cited figures range from about 30 to 36.

Those numbers are not exact. Wisdom was already an adult when she was first banded, and not every season was observed from beginning to end. The most conservative official estimates describe around 30 chicks successfully fledging.

Even the lower estimate is remarkable. Each chick represents months of shared incubation, long feeding flights and careful protection. It also represents another possible link in the future of the species.

That future is now visible in Wisdom’s own family.

In 2026, Friends of Midway Atoll confirmed that Wisdom had become a grandmother, with one of her offspring successfully breeding. One of her sons, identified by the band N333, has been observed nesting near the area where Wisdom herself returns.

Her family story shows how slowly, and how successfully, albatross generations can build. A bird Wisdom helped raise eventually returned to the same island and began raising a family of its own.

Wisdom survives a devastating tsunami

Wisdom’s life has not been easy. She has faced storms, changing ocean conditions, food shortages and the many hazards of life at sea.

One of the most serious events came in March 2011, when an earthquake-triggered tsunami swept across parts of Midway Atoll. The waves killed thousands of adult albatrosses and tens of thousands of chicks.

Wisdom survived.

The disaster showed both the vulnerability of Midway’s colonies and the strength of the birds that returned afterward. Albatrosses depend on remote islands for nesting, but they spend much of their lives in the wider Pacific, where they face pollution, fishing gear, plastic and changes in the ocean food supply.

Wisdom is not simply old because she has been lucky. Her survival also reflects the importance of protected habitat and years of conservation work at Midway Atoll.

Why Wisdom is famous

There are many famous animals in history: loyal dogs, working horses, heroic cats and beloved celebrity pets. Wisdom is different. She is not famous because she belonged to a person or appeared in a film. She became famous because researchers were able to follow her life for nearly seven decades.

Her band created a bridge between generations of scientists. Chandler Robbins first recorded her in the 1950s. Later biologists recognized her return, tracked her nesting, documented her mates and watched her offspring grow up.

Wisdom has outlived many of the people who studied her. She has also outlived several generations of albatrosses born on the same island.

Each time she returns, she offers scientists another piece of information about how long these birds can live, how often they reproduce and how their colonies respond to environmental change.

Wisdom’s enduring legacy

Wisdom’s greatest legacy may not be any single record. It is the living family tree she has created at Midway Atoll.

She has helped raise dozens of chicks. At least one of those offspring has now bred successfully. Her descendants may continue returning to the island long after Wisdom is gone.

Her story also reminds us that wildlife records are not just trivia. A bird’s age can reveal how much is possible when a species has a safe place to nest and a healthy ocean to depend on.

Wisdom has crossed millions of estimated miles, survived a tsunami and returned to the same remote island almost every November. At 75, she is still part of the colony’s annual rhythm: courtship, nesting, incubation and the hope of new life.

That is why Wisdom remains so loved. She is not only the world’s oldest known wild bird. She is a mother, a grandmother, a survivor and a remarkable ambassador for the ocean.

Robbins named her Wisdom when he banded her all those years ago. After everything, it still fits.
