Wisdom (albatross)
albatross, oldest confirmed wild bird and the oldest banded bird in the world
Wisdom (officially designated #Z333) is a wild female Laysan albatross, the oldest confirmed wild bird in the world and the oldest banded bird in the world. First tagged in 1956 at Midway Atoll by the United States Geological Survey (USGS), she was still incubating eggs as late as 2025 and has received international media coverage in her lifetime. She was spotted alive and apparently healthy as recently as November 2025.
Banding
Wisdom was first tagged in 1956 as #Z333 at the Midway Atoll National Wildlife Refuge by Chandler Robbins, a senior scientist at the USGS. At that time, she was estimated to be five years old—the earliest age that the Laysan albatross reaches sexual maturity—corresponding to a hatching date of the 1950–51 breeding season at the very latest. Birds are banded so that their populations can be monitored and individuals' longevity, behavior and migration patterns can be studied.
In 2006, John Klavitter, a United States Fish and Wildlife Service biologist at Midway, gave Wisdom her name while he was replacing her band.
The USGS has tracked Wisdom since she was first tagged and estimated that Wisdom has flown over 3,000,000 miles (4,800,000 km) since 1956 (approximately 120 times the circumference of the Earth). To accommodate her longevity, the USGS has replaced her tag six times.
Fertility
Laysan Albatrosses lay one egg per year, and usually have monogamous mates for life. Smithsonian speculated that, due to Wisdom's unusual longevity, she has had to find several successive mates in order to continue breeding.
Begin with the source’s own compact description: “Wisdom (albatross)” is albatross, oldest confirmed wild bird and the oldest banded bird in the world. The dossier treats that line as a proposition to test through Wisdom, albatross and oldest, not as a finished interpretation.
Why this record matters
The phrase “albatross, oldest confirmed wild bird and the oldest banded bird in the world” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 18, 2026. The linked authority identifier is Q21191331. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1956, 2025, 1950 and 2006.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
