Wisdom’s (the world’s oldest known Laysan Albatross Phoebastria immutabilis) first banded chick fledged from Sand Island, Midway Atoll in the 2010/11 season bearing colour band red N333.  As a chick it had survived the 11 March 2011 tsunami that inundated most of Midway’s Eastern Island, as well as parts of Sand Island.  The bird, thought to be a male due to its larger bill size, was regularly sighted near Wisdom’s nest site over 2018-2021.

It was first recorded breeding in the 2021/22 season with mate DH00 some 160 m away from Wisdom's usual nest site among bushes close to the shoreline.  Their chick was found dead in May 2022 at around four months of age.  The next season (2022/23) N333 was back at the same nest site on a pipping egg on 13 February 2023, which hatched the next day, and survived at least until May.  Information on the outcome of the 2022/23 chick and of the 2023/24 season is not currently available.

N333 is now incubating its 2024/25 egg at the same nest site, where it was videoed by Dan Rapp on 12 December 2024,  He is 14 years old and his egg is due to hatch any day - as is Wisdom’s own egg. The first recorded Laysan Albatross chick on Midway this season was seen on 20 January.
