World’s oldest-known wild bird lays an egg in Hawaii at age 74

This bird’s no spring chicken — but she’s procreating in her 70s!

The world’s oldest known wild bird, an albatross named Wisdom, triumphantly laid her first egg in years this week at the ripe old age of 74.

“We are optimistic that the egg will hatch,” Jonathan Plissner, supervisory wildlife biologist at Midway Atoll National Wildlife Refuge in Hawaii said.

The long-winged seabird popped out the potential baby near the Hawaiian Archipelago islands after returning there with her mate earlier this week.

The frisky fogey and her life-long lovebird, Akeakamai, had flown back to the circular chain of reef islands to lay and hatch eggs since 2006.

But Wisdom hadn’t laid an egg in four years after Akeakamai apparently flew the coop and disappeared several years ago.

Wisdom was later seen interacting with another male before she recently reunited with her long-term mate.

The bird  — who has laid an estimated 60 eggs in her life — was first banded as an adult in 1956 and has raised as many as 30 chicks, Plissner said.

The average lifespan of a Laysan albatross, which mate for life, is 68 years, according to the National Oceanic and Atmospheric Administration.

The age at which the birds stop laying eggs in the wild hasn’t been effectively studied and is unknown.

Every year, millions of the seabirds return to the refuge to nest and raise their young and their chicks fly out to sea about five to six months after hatching.

They spend most of their lives soaring over the ocean and feeding on squid and fish eggs.
