World’s Oldest Wild Bird a New Mom — Again

A Laysan albatross named Wisdom just hatched a new chick on the Midway Atoll National Wildlife Refuge.

Wisdom, who is at least 62, is not only the world’s oldest-known wild bird, but she’s also the oldest-known wild bird mom.

Wisdom has sported and worn out 5 bird bands since she was first banded by noted U.S. Geological Survey scientist Chandler Robbins in 1956 as she incubated an egg. Chandler rediscovered Wisdom in 2001. In 1956, he estimated Wisdom to be at least 5 years old then since this is the earliest age at which these birds breed, though they more typically breed at 8 or 9 after an involved courtship lasting several years.  This means, of course, that Wisdom could be even older than 62.

Welcome to the World, Chick! The Oldest Bird in the World Raises a Chick


Rewriting the Record Books

“As Wisdom rewrites the record books, she provides new insights into the remarkable biology of seabirds,” said Bruce Peterjohn, chief of the North American Bird Banding Program at the USGS Patuxent Wildlife Research Center in Laurel, MD.  “It is beyond words to describe the amazing accomplishments of this wonderful bird and how she demonstrates the value of bird banding to better understand the world around us. If she were human, she would be eligible for Medicare in a couple years yet she is still regularly raising young and annually circumnavigating the Pacific Ocean.”

And since adult albatross mate for life, with both parents raising the young, it makes one wonder if Wisdom has had the same partner all these years or not.

Wisdom is now the oldest wild bird documented in the over 90-year history of the USGS, U.S. Fish and Wildlife Service and Canadian bird banding program.  “To know that she can still successfully raise young at age 60-plus is astonishing,” Peterjohn said. “While the process of banding a bird has not changed greatly during the past century, the information provided by birds marked with a simple numbered metal band has transformed our knowledge of birds.”

Wisdom has likely raised at least 30 to 35 chicks during her breeding life, though the number may well be higher because experienced parents tend to be better parents than younger breeders.  Albatross lay only one egg a year, but it takes much of a year to incubate and raise the chick. After years in which they have successfully raised and fledged a chick – which on Midway is about two-thirds of the time – the parents may take the occasional next year off from parenting.

Wisdom also nested in 2006, and then every year since 2008.  Wisdom and her 2011 chick survived the tsunami that resulted from the Tohoku Earthquake that March. The tsunami, which washed over the Midway Atoll National Wildlife Refuge, resulted in tremendous losses of Laysan and black-footed albatross at the refuge — an estimated 110,000 chicks and 2,000 adult albatross died. 

Frequent Flyer Miles

Almost as amazing as being a parent at 62 is the number of miles this bird has likely logged – about 50,000 miles a year as an adult – which means that Wisdom has flown at least 2 to 3 million miles since she was first banded. Or, to put it another way, that’s 4 to 6 trips from the Earth to the Moon and back again with plenty of miles to spare.

One reason for all these miles is that Laysan albatross spend the first 3 to 5 years after fledging at sea, never touching land. Then they return to breed in the northwestern Hawaiian Island chain but some of their feeding grounds are actually off the coast of western North America, including the Gulf of Alaska. The parents tend to feed closer to the islands where their nests are when the chicks are very young, but they regularly commute to the northern Pacific Ocean and even the Gulf of Alaska when the chicks are older or when the adults are incubating.  They convert the fish and squid they eat into a rich, oily liquid, which they regurgitate and feed to their chick.

In the non-breeding part of the year, albatross do not touch land — the birds, scientists believe, often even sleep while flying over the ocean.

Why Band Birds?

Peterjohn noted that Wisdom’s remarkable record is just one example of the valuable data provided by bird banding. In addition to establishing longevity records for birds, banding data from the North American Bird Banding Program documents migratory patterns, provides critical harvest and survival information used to manage populations of migratory game birds, and supports research activities on many issues from toxicology to disease transmission and behavior. Since 1920, approximately 68 million birds have been banded by this Interior Department-Canadian Wildlife Service program, and of those, over 4.5 million bands have been recovered.

About Albatross

Albatross are legendary birds for many reasons – in Samuel Coleridge’s poem, “The Rime of the Ancient Mariner,” a sailor has to wear an albatross around his neck as punishment for killing the bird. According to seafaring legends, albatross are the souls of lost sailors and should not be killed. However, as reported by James Cook, sailors regularly killed and ate albatross.

Albatross are remarkable fliers who travel thousands of miles on wind currents without ever flapping their wings. They do this by angling their 6-foot wings to adjust for wind currents and varying air speeds above the water.

Nineteen of 21 species of albatross are threatened with extinction, according to the International Union for the Conservation of Nature. Present threats to the birds include lead poisoning of chicks on Midway from lead paint used in previous decades; longline fishing, where the birds are inadvertently hooked and drowned, though conservation groups have banded with fishermen and dramatically lowered the number of deaths from this cause; and pollution, especially from garbage floating on the ocean.

The birds ingest large amounts of marine debris – by some estimates 5 tons of plastic are unknowingly fed to albatross chicks each year by their parents. Although the plastic may not kill the chicks directly, it reduces their food intake, which leads to dehydration and most likely lessens their chance of survival. In addition, albatross are threatened by invasive species such as rats and wild cats, which prey on chicks, nesting adults and eggs. Albatross evolved on islands where land mammals were absent, so have no defenses against them.
