Wisdom (albatross)
Wisdom is a wild female Laysan albatross. She is the oldest confirmed wild bird in the world as well as the oldest banded bird in the world.
==Biography==
Wisdom hatched in or around 1951. In 1956, at the estimated age of five, she was tagged by scientists at the Midway Atoll National Wildlife Refuge for study, but then returned to the wild rather than being kept in captivity. The person to attach the first tag was Chandler Robbins, a now retired senior scientist at the United States Geological Survey.〔 Birds are banded so that they can be studied, including their locations, flight patterns, longevity, and a myriad of other data that can be collected.
On December 3, 2014, Wisdom made headlines when she laid an egg at the Midway Atoll. Her mate had arrived at the atoll on November 19 and Wisdom was first spotted by the refuge staff November 22. The egg was estimated to be number 36 for Wisdom over her lifetime. Albatrosses lay one egg per year and have monogamous mates for life. Out of the last nine years, Wisdom has laid an egg for eight of them. ''Smithsonian'' has speculated that since Wisdom is so unusually old for her species, she may have had to find another mate to keep breeding.
The USGS have tracked Wisdom since she was tagged, and they have logged that Wisdom has flown over three million miles since 1956. To accommodate her increasing longevity, the USGS has replaced her tag a total of six times.
