Wild California Condors Create First Egg in 15
Years
According to Cat Lazaroff,
for the first time in fifteen years, a California condor has laid an
egg in the wild.
The egg was found broken but the biologists
say is not an unusual
occurrence for condors on their first
nesting attempt and this
illustrates the success of the captive
breeding program that
removed the last California condor from the
wild in 1986.
Meanwhile, five more young California condors are
scheduled to be released into
the wild next week.
In 1986, the last free
flying wild California
condor was found and
placed in a captive
breeding program.
The first egg to be laid by a
reintroduced California
condor was discovered on
Sunday in Grand Canyon
National Park. Biologists from
The Peregrine Fund found
the egg in a cave in the Grand Canyon after
observing nesting
behavior at the same location for the past
several days.
"It was so incredible, I kept doubting that
it was really an egg at
first," exclaimed Sophie Osborn, field
biologist for The Peregrine Fund.
"Although my first reaction was that it was
an egg, since it would be
the first from a reintroduced condor, I had
to control my emotions
and confirm what I was seeing."
"Any doubt I had was gone a short time
later when a condor flew into
the cave and moved the egg around,"
continued Osborn. "As soon as
I was able to confirm that it was in fact
an egg, I was able to
express my elation and immediately called
the office. It was a
remarkable sight, a remarkable moment, and
I wanted to share it with
my co-workers who have worked so long and
hard toward this day!"

on the Vermilion
Cliffs
The female condor
who laid the egg was
herself hatched in
March of 1995. In May 1997, along with
eight other
condors, she
was released on the
Vermilion Cliffs close by the
Grand Canyon
National Park.
Condor
reintroduction effort is part
of a joint project
between The Peregrine
Fund, U.S. Fish and
Wildlife Service
(USFWS), Bureau of
Land Management
(BLM), Arizona Game
and Fish, National
Park Service (NPS),
CORE, and numerous
other partners.
"This is the first California Condor egg
laid in the wild since 1986!
What an important step forward for the
entire reintroduction
program," said Mike Spear,
California/Nevada Operations Manager for
the USFWS. "The cooperative efforts of all
our partners are making a
real difference in the conservation of the
condor."
Although this is a critical step in
establishing a viable wild breeding
California condor population, the egg was
broken by one of the
condor pair.
"This is very exciting news. For egg laying
to have occurred the first
year it is biologically possible is
remarkable!" said Susan MacVean,
nongame specialist for the Arizona Game and
Fish Department. "We
hope this means we can look forward to wild
hatched condor chicks
in Arizona over the next two to three
years."
A captive California condor
Biologists believe there is a chance the
condor pair may re-nest this year.
Condors are a notoriously slow breeders
and the first mating attempts
generally do not occur until the birds are
at least
six years.
"We are pleased that the reintroduced
California condors chose Grand Canyon
National Park as the place where they
made their first nesting attempt," said Joe
Alston, superintendent of Grand Canyon
National Park.
Historically, condors ranged from British
Columbia south to northern
Baja California and in other parts of
southwestern United States.
Shooting by hunters and farmers, poisoning
by baited or lead shot
contaminated carcasses, and loss of habitat
had brought the species
to the brink of extinction by the 1970s.
A difficult decision to capture the remaining condors was made when
Norton was an Associate Solicitor at the Interior Department during
the mid-1980's when the last seven wild
California condors were
captured. "The California condor was on the
absolute brink of
extinction."
A captive breeding program
has helped boost condor numbers in part
because the birds can be
prompted to lay up to three eggs per year
in captivity - in the wild,
condors generally lay just one egg every
other year.
Some of the California condors are now
being released as a
"non-essential/experimental population"
under the Endangered
Species Act, meaning that the species can
be released in an area
without affecting current or future land
use planning.
Biologists hope the egg
heralds
a new era of wild
born
California condors.
Currently
just
160
California condors exist in
the
world - 49 in the wild in
California and Arizona, 10 in
pre-release field pens in
California, and 101 in
captive
breeding facilities
at the
World Center for
Birds of Prey, the Zoological Society of
San Diego, and the Los
Angeles Zoo.
On April 5, Interior Secretary Gale Norton will participate in the
release of five young condors into the
Ventana Wilderness near Big
Sur, California.
"This is a particularly fulfilling day for
me," Secretary Norton said.
