With the Olympics going on in Russia, it’s not clear why the
local media haven’t picked up on perhaps the most amazing athletic performance
in the animal world—at the western end of the Hawaiian archipelago.

World's oldest wild bird produces chick, in Hawai`i.
That’s where the oldest wild bird known has just produced
another offspring.

The Laysan albatross nicknamed “Wisdom” has been faithfully
producing new albatrosses for more than half a century. Wisdom is at least 63
years old—she was already a mature adult when she was banded in 1956.
This year, she is raising yet another chick. Like other
albatross, she will fly thousands of miles to collect food for the youngster—as
she has for her earlier offspring for decades. It is estimated that Wisdom and
her mate have raised 30 to 35 young in their lives, and maybe more. She
produced one last year as well, and one at age 60 in 2011.
Dan Clark, manager of the Midway Atoll National Wildlife
Refuge, within the Papahānaumokuākea Marine National Monument, called the bird
an “inspiration and hope for all seabird species.”
“She provides to the
world valuable information about the longevity of these beautiful creatures. In
the case of Wisdom, she has logged literally millions of miles over the Pacific
Ocean in her lifetime to find enough fish eggs and squid to feed herself and
multiple chicks, allowing us the opportunity to measure the health of our
oceans which sustain albatross as well as ourselves,” Clark said.
To be clear about how remarkable this is, Wisdom is a fully functioning and reproducing
albatross at twice the normal albatross life span. If you go here, they’ll tell
you the lifestpan of a normal Laysan albatross is 12 to 40 years.
Wisdom has survived and thrived in the face of significant
threats to her species.
“It is a poignant and overwhelming reality that plastics
discarded at sea float, from toothbrushes to millions of bottle caps, float
and, are used as a substrate for flying fish to attach their eggs, a food
highly prized by foraging albatross and ultimately regurgitated into the
chick’s mouth,” said refuge biologist Pete Leary.
