Hunters have been using lead
bullets for decades to kill game with
little, if any, side effects. But new
research finds that hunters may need
to use more caution when choosing their
bullets. Reporter Sadie Babits has this
story on a hidden danger that’s just
coming to light:

Tony Hanson has been hunting wild game all of his life. And over the years, he’s
grown pretty attached to what he considers the most cost effective, most efficient
bullet around – a lead bullet.

“It matters a lot to a hunter. You are counting on the range of that bullet. You know
what the bullet can do and you know what the gun will do. You’re out there to take
an animals life, and that’s not something we take lightly.”

The typical bullet used by most hunters is made up of about 65% lead. The bullet is
capped off with a copper jacket. These bullets are designed to handle high speeds and
to kill an animal quickly without breaking apart and sending tiny lead fragments
throughout the meat. Hanson works with the country’s largest conservation group –
Michigan United Conservation Clubs. He says he’s not concerned about possible
lead poisoning.

“Generally speaking, if you make the shot you are supposed to make you’re not
getting any edible meat. It’s not something that really weighs into my thought too
much. ”

Like Hansen, most hunters don’t give lead bullets a second thought. So why worry?

Well, early last spring, food pantries across North Dakota and Minnesota were
advised not to give out donated ground venison. That’s after lab tests revealed tiny
lead fragments in some of the meat.

It generated enough interest that North Dakota launched a study involving some 700
people. The Centers for Disease Control and Prevention worked with North
Dakota’s Health Department. They found that people who ate a lot of wild game
tended to have higher lead levels in their blood than those who ate very little or no
wild game.

The results validated similar research involving California Condors. The Condors
almost went extinct in large part because of lead poisoning. You see, the birds would
feed on gut piles and carcasses left by hunters, and, if those hunters used lead bullets,
the condors would get sick.

That old problem still exists. Lead poisoning remains the number one obstacle
standing in the way of restoring the California Condors.

Rick Watson is the vice president of the Peregrine Fund in Boise, Idaho. He says
they’ve tracked the birds through satellites to see what they feed on. They’ve also
shot deer in the same way a hunter would, using typical lead bullets. The animals
were then x-rayed.

“And we were astounded by the results. Typically out of the 30 or so deer all of them
had fragmented lead bullets in them. And we were also amazed about the actual
extent the lead fragments are sprayed throughout the meat.”

Watson says about 5% of a bullet does break apart and some of it gets into the meat.
He’s now working on another study to see the impact of lead bullets on people.
That’s involved shooting more deer, sending the meat to random processors, and
then running that meat through an x-ray machine. The findings, he says support
what North Dakota discovered late last fall.

“And again what we found that 30% of the packages of meat that came back had at
least one fragment of lead in them.”

Not enough to make a person sick, but enough to raise a red flag. Watson says the
solution is simple. Hunters need to use non-toxic lead bullets. But most hunters
aren’t convinced. So-called green bullets are about twice the cost of lead bullets and
hunters don’t believe they are as efficient.

Hunters say they want independent research done before anybody starts making the
switch to non toxic bullets.

Lead Poisoning and California Condors

It’s been decades, but there are now more California Condors in the wild than there
are in captivity. That’s thanks to two condor chicks who recently left their nests in
the Grand Canyon. As Sadie Babits reports, biologists are thrilled, but one of the
problems that caused the decline in condors still exists:

It’s been decades, but there are now more California Condors in the wild than there
are in captivity. That’s thanks to two condor chicks who recently left their nests in
the Grand Canyon. As Sadie Babits reports, biologists are thrilled, but one of the
problems that caused the decline in condors still exists:


At the World Center for Birds of Prey in Boise, Idaho, there’s a wood fence that
protects the California Condors that live behind it.

“Just lately in order to minimize the exposure of our adult breeding pairs to humans,
we’ve built this security fence or actually it’s a visual barrier, we call it.”

That’s Bill Heinrich. He overseas the California Condor Recovery program at the
Center.

There is this one small break in the fence – a part that hasn’t been built yet. And
behind some chain link, I can see some very large birds…

Sadie: “Is that a Condor right there??”

Bill: “Yeah… you can see an adult condor standing, a pair of them on a perch.”

Sadie: “Ooohhhh!”

Bill: “You can kind of get an idea of just how big they really are.

Sadie: “They’re huge!”

Bill: “They weigh anywhere from 18-25 pounds and have close to a 10 foot wingspan.”

In the early 1980s the California Condors almost went the way of the Dodo –
extinct. Only 22 of these birds remained in the wild.

The big birds were killed by hunters. They died from lead poisoning after eating
animals killed with lead bullets. And their own genetic makeup didn’t help much
either.

These birds, shall we say, have a low sex drive. Rather than produce chicks every
year and gamble that they’ll survive, condors lay one egg every other year. That
hasn’t worked so well.

So biologists thought they’d help. They started capturing the endangered condors to
begin a captive breeding program. In 1987, the last wild bird was caught.

Bill Heinrich recalls there was plenty of controversy over that decision.

“People thought well you should let them go extinct with dignity or you can try to
breed them in captivity but you might fail and then you would have lost them in the
wild that much quicker.”

But the move saved the birds from being killed by hunters or from eventual lead
poisoning.

And, the breeding program, well, let’s just say the numbers speak for themselves.
Down to 22 birds in 1987, today there are now 327 California Condors. And more
than half of those birds are back in the wild.

Bill Heinrich says next spring some of these condors will be released some where
around the Grand Canyon in Arizona.

That’s where the birds will once again be exposed to one of the factors that lead to
their decline. It’s not hunters these days. The birds are protected by the Endangered
Species Act. But lead poisoning. Condors feed on gut piles and carcasses left by
hunters. If a hunter uses lead bullets, the bullet will explode sending tiny fragments
of lead through the meat. It’s enough to make a condor sick. Heinrich says lead
poisoning remains the single biggest threat to the birds.

“You know if hadn’t been for the lead issue coming up, I would have thought, I
didn’t have any reservations about it being successful until the lead problem cropped
up.”

Every year, biologists have to test the birds for lead poisoning. They’ve been working
with the Arizona Game and Fish Department to hand out free non-lead bullets to
hunters in the area. Last year, not a single condor died from lead poisoning. This
year, biologists have had to treat six birds, all of which are expected to make a full
recovery.

In California, the state has banned lead ammunition because of the lead poisoning
concern. But hunters don’t think lead bullets are a real problem, and they really
don’t want to pay for different kinds of bullets because that is a lot more expensive.

Non-Toxic Alternatives for Waterfowl Hunters

The federal government is getting ready to approve new types of non-toxic ammunition for shooting ducks and geese… but the government isn’t even thinking about tackling a related issue. The Great Lakes Radio Consortium’s Lester Graham reports:

The federal government is getting ready to approve new types of non-toxic ammunition for
shooting ducks and geese… but the government isn’t even thinking about tackling a related issue.
The Great Lakes Radio Consortium’s Lester Graham reports:


The U.S. Fish and Wildlife Service is in the process of approving three new types of non-toxic
shot for waterfowl hunting. Shotgun shell pellets used to be made of lead. But years of lead
pellets dropping into the wetlands found foraging waterfowl eating the lead and dying. So, lead
shot was banned in 1991. Since then, manufacturers have been looking for new shot formulations
that work well for hunters, but are non-toxic.


Nicholas Throckmorton is with the Fish and Wildlife Service and he says new kinds of shot give
hunters some options.


“Hopefully, late spring, early summer the three companies will be allowed to sell their new shot
formulations.”


While lead shot is banned, the government isn’t doing anything about lead bullets. Rifles still
use lead slugs. Game that is shot, but gets away is usually eaten by predators or scavengers.
Some of the animals, such as the endangered condor, have died from lead poisoning.
