The California Condor - Gymnogyps californianus - is the largest North American land bird. Currently, this condor inhabits only the Grand Canyon region.
It is a large, black vulture
with patches of white on the underside of the wings and a largely bald
head with skin color ranging from yellowish to a bright red, depending
on the bird's mood. It has the largest wingspan of any bird found in North America and is one of the heaviest, weighing up to 29lbs. The condor is a scavenger and eats large amounts of carrion. It is one of the world's longest living birds, with a lifespan of up to 60 years.
Condor numbers dramatically declined in the 20th century due to habitat destruction, poaching and lead poisoning. Eventually, a conservation
plan was put in place by the United States government that led to the
capture of all 22 remaining wild condors in 1987. These surviving birds
were bred at the San Diego Wild Animal Park and the Los Angeles Zoo. As of April 2011, there are 384 condors
known to be living, including 181 in the wild.
The condor is a significant bird to many Californian Native American groups and plays an important role in several of their traditional myths.
Three more California Condors, among the most endangered birds in
the world, have died from lead poisoning from ammunition, while three
others were treated for lead poisoning, according to The Peregrine
Fund’s Condor Recovery Program in Arizona. This brings the total number
of condors killed by lead in the last 11 years to 19.
“This tragic news comes as little surprise for those of us engaged
in the lead ammunition issue. We expect more condor, eagle, and other
bird deaths as long as lead remains an ingredient in bullets and shot
used for hunting,” said George Fenwick, President of American Bird
Conservancy.
“Ammunition manufacturers have introduced superior nontoxic
ammunition both for shotguns and for hunting rifles, and hunters report
the newer nontoxic bullets outperform traditional ammunition. The
cost of nontoxic ammunition is now the same as for premium lead
ammunition, that used by the majority of hunters. The increase in
performance at no additional cost should encourage hunters to switch to
nontoxics,” he said.
Ironically, this event comes at a time when some members of Congress
are trying to initiate action (House Bill – HR 1558 – and a Senate
Bill – S.838.IS) that has the potential to further entrench the use of
lead ammunition and result in additional poisoning of wildlife by
preventing the U.S. EPA from regulating this highly toxic substance.
Approximately 30 condors were captured for testing after a hiker
found one dead. Of those captured, five were found to have high levels
of lead poisoning. Two of those later died. The San Diego Zoo’s
Institute for Conservation Research performed the necropsies.
“X-rays showed 18 shotgun pellets in the digestive system of one
bird and six in another. The third had remains of a spent bullet in its
system, all suggesting these scavengers died after eating one or more
animal carcasses that had been shot,” said Chris Parish, head of The
Peregrine Fund’s condor recovery program in Arizona.
The deaths come only weeks after a study by scientists at the
University of California, Santa Cruz, the University of Wyoming, the
U.S. Fish and Wildlife Service, and the National Park Service concluded
that over one-third of the population of wild condors is chronically
exposed to lead specifically identified by its chemical signature as
being derived from spent ammunition.
Lead is a highly toxic substance that is dangerous to wildlife even
at low levels. Exposure can cause a range of health effects, from loss
of coordination and nerve damage to acute poisoning and death.
Long-term effects can include mental retardation, reduced reproduction,
and damage to neurological development.
Up to 10 million birds and other animals die each year from lead
poisoning in the United States, including Bald Eagles, Golden Eagles,
Loons, Trumpeter Swans, and doves. This occurs when animals scavenge on
carcasses shot and contaminated with lead bullet fragments, or pick up
and eat spent lead shot pellets or lost fishing weights, mistaking
them for food or grit. Some animals die within days, while others
suffer for years from lead’s debilitating effects.
Lead ammunition also poses health risks to people. Lead bullets
fragment on impact into minute particles, spreading throughout game
meat that people eat. X-ray studies show that hundreds of dust-sized
lead particles can contaminate meat more than a foot and a half away
from the bullet track. A recent study found that up to 87% of game
killed by lead ammunition contains unsafe levels of lead when consumed
by pregnant women or children. Nearly ten million hunters, their
families, and low-income beneficiaries of venison donations may be at
risk.
“The wildlife community needs to do a better job of educating
hunters to the long-term damage that lead ammunition can cause to both
wildlife and humans, and in countering the false claims by the gun
lobby that this is somehow a conspiracy to ban guns. We need those
hunters who already know this to help spread the word among their
fellow sportsmen and women that this is simply the right thing to do,”
said Fenwick.
The U.S. military recently announced their decision to switch to
non-lead ammunition for certain small arms, calling the new bullets one
of the greatest advancements in small arms ammunition in decades. This
news undermines claims that non-lead ammunition is somehow inferior to
lead-based ammo.
“If it’s good enough for our soldiers on the field of battle, then
lead-free ammunition should be good enough for us to hunt with,” said
Fenwick, himself a hunter.
