Can Wisdom save the world's albatross population?
March 19, 2014
They see colorful bits of
plastic in the ocean and confuse them for food. Many of them fly back
with toothbrushes, lighters and other plastic products to feed their
young. The end result is grim.
And that's just part of the problem.
According to a study, "Facing Extinction: The World's Rarest Birds and the Race to Save Them," around 100,000 albatrosses are killed by longline fishing each year. That's almost 300 every 24 hours.
This form of fishing is a
commercial technique that uses huge lines -- often kilometers long --
with deadly baited hooks strung out by fleets of fishing boats. Some
barely survive increasingly extreme weather conditions, while others die
because of starvation due to declining fish stocks, as well as marine
pollution and other predators.
Nineteen of the 22 species of albatross face extinction, according to the University of South California.
But there is hope.
Wisdom is a Laysan
albatross, a species that usually inhabits the Northern Pacific, and is
thought to be around 63 years old. She's exciting biologists because of
her advanced years -- the average life span of a Laysan albatross is 12 to 40 years old. Scientists hope this is good news for the population.
"She's such an
inspiration," said Amanda Fortin, of the U.S. Fish and Wildlife Service.
"Wisdom is one bird that has captured the hearts of people around the
world because she represents an entire imperiled species."
What makes Wisdom even
more special is that she is still mating -- she has raised at least 35
chicks in her lifetime and has nested consecutively every year since
2008, according to Bruce Peterjohn, chief of the North American Bird
Banding Program at the USGS Patuxent Wildlife Research Center. They even
set up a camera and recorded her when she laid an egg in December.
"She's such a celebrity now," said Peterjohn.
She delivered her youngest chick
just a few weeks ago, which raises eyebrows because albatrosses are
known to have low reproductive rates. If they live to see adulthood,
they typically only breed every two years.
Researchers are still trying to determine how she is able to have babies and why she has lived longer than others.
A rare breed
Biologists spotted Wisdom in 2001 at Midway Atoll,
a national wildlife refuge north of the Hawaiian archipelago. But the
red band they discovered attached to one of her feet amazed them. It was
soon revealed that Chandler Robbins, a former ornithologist at the
Patuxent Center, placed the band on her in 1956 as a tracking device.
"I was really surprised.
I didn't expect to ever find her again," said Robbins. "Finding her
made me realize that these birds live longer than expected."
Even in her golden
years, Wisdom's thick coat of white feathers that trail off to gray and
black appears untouched. Her astounded supporters periodically capture
photographs of her where her eyes give off a mysterious glare that
reveal a world of experience no one may ever know.
Wisdom's exact birthday is unknown but it is safe to say that she has at least lived through the Vietnam War, says Peterjohn.
"I've run out of
adjectives to describe this whole situation. If you relate it to human
terms you'll understand. She is 63 years old, still having babies, still
successfully raising young and spending the rest of the time wandering
out on the Pacific Ocean -- I don't know what adjective you can use to
describe it," said Peterjohn. "I mean 'amazing' doesn't even do it
justice."
The famous bird has aroused so much interest that Darcy Pattison and Kitty Harvill wrote and illustrated Wisdom, The Midway Albatross: Surviving the Japanese Tsunami and other Disasters for over 60 Years in her honor.
'There's a lot we can do'
Fortin learned about Wisdom several years ago via email and immediately fell in love. She eventually began writing for the Service's Pacific region Tumblr blog
that monitored Wisdom's progress and eventually began writing posts
where she discussed some fundamental steps necessary to preserve the
almost-extinct albatross species.
"Imagine if we all took a
cue from Wisdom and used our seemingly small steps to combat climate
change or contribute to conservation? What begins as a single idea can
hatch, and fledge into stronger, more numerous acts that take flight and
make a dramatic difference. This spirited albatross has inspired and
amused people around the globe for decades. Hopefully, she has shared
some Wisdom too," she wrote in a post on the blog late last year.
Some in the longline
fishing industry -- largely blamed for deaths of many albatrosses -- are
implementing new techniques that are having a positive impact, said
Pete Leary , a biologist with the U.S. Fish and Wildlife Service.
"They are making a
difference. There's a long way to go but we continue to see increases in
North Pacific albatross populations," he said.
But Wisdom's story offers hope for albatrosses.
"It's just
flabbergasting that a bird that old can live a normal life and raise
young," said Peterjohn. "It'll be really fascinating to see how long she
lives."
