Unbelievable: Find Out The Age Of The World’s Oldest Known Bird
Unbelievable: Find Out The Age Of The World’s Oldest Known Bird: A Laysan albatross (Phoebastria immutabilis) called Wisdom who is believed to be at least 68 years old, recently hatched a new chick at her nesting ground in Midway Atoll National Wildlife Refuge.
One may ask, how come Wisdom is said to be more that 68 years?
These birds are branded and tracked. The very first albatross on the Midway Atoll was given a band and number in 1936. Since then, 250,000 albatrosses have been banded, letting researchers keep track of specific birds.
Wisdom was banded in 1956 by ornithologist Chandler Robbins. At the time, she was estimated to be around six years of age because she had returned to the breeding site as an adult, which these birds don’t do until they’re around five and ready to find a mate.
Let’s do the Maths then, if Wisdom was five in 1956 (although she could have been older), it would mean that she is at least 68 years old today.
After a brief hiatus, Robbins found and re-tagged Wisdom during the 2001/2002 season and since then she’s been a regular visitor of the Midway Atoll.
Albatross’ generally have a life span of about 50 years and in a world that’s plagued by fear of extinction and climate change, it’s so refreshing to find that some animals like Wisdom are beating the odds.
Together with her mate Akeakamai, Wisdom has raised between 31 and 36 hatchlings.
