Wisdom: The Oldest Known Albatross, Still Nesting at 67
Longevity and Resilience
Wisdom, the world’s oldest known wild bird, has once again laid an egg at the remarkable age of 67. This Laysan albatross has been nesting on Midway Atoll in the Papahānaumokuākea Marine National Monument since 2006, raising at least nine chicks with her lifelong mate, Akeakamai. It is estimated that over her lifetime, Wisdom has raised an astonishing 30 to 35 albatross chicks, outliving several of her mates.
Scientific Significance
Wisdom’s longevity and reproductive success have made her an icon in the scientific community. Biologists are fascinated by her ability to survive and reproduce at such an advanced age, challenging previous assumptions about the lifespan of wild birds. Her continued nesting provides valuable insights into the resilience and adaptability of albatross species.
Conservation Icon
Wisdom has also become a symbol of the conservation challenges facing seabirds. Laysan albatrosses are listed as Near Threatened by the IUCN due to threats such as invasive species, fishing nets, oil spills, and plastic pollution. Wisdom’s story highlights the importance of protecting their nesting grounds and mitigating these threats to ensure the survival of her species.
Nesting Habits
Laysan albatrosses are monogamous birds that typically return to the same nesting site each year. They form long-term pair bonds and share responsibilities for incubating their single egg. Unlike some other seabird species that lay multiple eggs, albatrosses invest heavily in raising a single chick, making each egg crucial for the survival of the colony.
Egg Incubation
Wisdom and Akeakamai will share egg-tending duties, switching off every two to three days while the other forages for food. It takes approximately two months for an albatross egg to hatch, so the chick is expected to arrive in mid-February or earlier.
Threats to Albatrosses
Despite their remarkable adaptations, albatrosses face numerous threats throughout their lives. On their nesting grounds, they are vulnerable to invasive mammals like foxes and rats. At sea, they encounter fishing nets, longlines, oil spills, and plastic pollution. Wisdom’s survival and longevity are a testament to her resilience and the importance of conservation efforts to protect her species.
Wisdom’s Journey
Over her lifetime, Wisdom has traveled an estimated two to three million miles, navigating the vast oceans and avoiding countless threats. Her journey serves as a reminder of the interconnectedness of our planet and the challenges faced by migratory species.
Conclusion
Wisdom’s story is an extraordinary tale of longevity, resilience, and conservation. Her continued nesting at the age of 67 is a testament to the adaptability and resilience of these magnificent birds. As a symbol of the challenges facing seabirds, Wisdom’s legacy inspires us to protect their habitats and ensure the survival of her species for generations to come.
