Every year, tens of thousands of avid birdwatchers wander through
frozen fields and marshy swamps. Their job is to record as many birds
as they can find in a given area. For birders, it’s a day to enjoy the outdoors
while doing what they love most. But as the Great Lakes Radio Consortium’s
Karen Kelly reports, that passion serves another purpose – it helps scientists:


(sound of footsteps)


Georgina Doe: “There’s five robins right there and there’s three common mergansers,
males…”


Georgina Doe scans the shoreline with her binoculars. Within seconds,
she spots a tiny glimpse of a bird and names it.


She knows them by the way they dive in the air, and the way they thrust
their chests out.


Doe has been scanning the treetops of Carleton Place, Ontario for
more than 30 years. She says she loves the chase and the element of surprise.
And over the years, birding has also been her escape.


She remembers watching a robin build its nest when her grandson
was seriously ill.


“So I used to count the birds every morning before I went off to
the hospital. And then after that, you come back to reality. Somehow a
little bird can just make you feel better.”


Birds have been a part of all of our lives. We might not know their names.
But we can remember holding a baby chick. Or hearing a cardinal on a crisp cold day. But now, many bird species are dwindling. And scientists are
counting on birders like Georgina Doe to help them find out why.


Doe is one of many birders in North America who collects
information for scientists. Jeff Wells works with that information
at Cornell University’s Lab of Ornithology.


“There’s no way that we could ever pay the tens of thousands of
trained biologists that would be necessary to gather this kind of
information. It’s only possible when we can engage volunteers like
we do in citizen science projects.”


Cornell runs at least a dozen programs that rely on information
from average birders.


There’s the Christmas Bird Count. About 50 thousand people participate.
Another 50 thousand track species during the Great Backyard Bird
Count in February.


The volunteers reported that wood thrushes are disappearing in
many areas. And they’re tracking the effect of the West Nile Virus
on bird populations.


“If a little bird dies, usually it just disappears quickly
and no one ever sees it. So we don’t really know the impact.
And so looking at the differences in the numbers and distribution
might give us some sense of when the disease was rampant in the summer,
whether it killed off enough birds to make a noticeable
difference in our count.”


(sound of quiet footsteps)


Robert Cermak: “You can see it’s about 10 inches high. It’s all fluffed
up right now…”


Birder Robert Cermak tiptoes closer to a barred owl sitting in the
crook of a tree. We’re in Ottawa, Canada’s capital and a city of about a million
people. When it comes to bird counts, this is Cermak’s territory.


“It’s not often that you see a barred owl, any owl, during
the day. They’re usually more secretive. This one is not too
afraid to be out so it’s probably more accustomed to having people
around it, since this is the center of the city.”


Like Georgina Doe, Cermak has been birding for years. But even with
veterans, there’s always concern about their accuracy. Cermak
discovered this firsthand when he reported seeing a rare
harlequin duck last year.


“I sent it in and a few hours later, someone from Cornell –
very politely because it’s a delicate subject to question
someone’s sighting of a rare bird – but they very delicately
indicated that a harlequin duck is extremely unusual in Ontario and
could I please provide a few extra details.”


Cermak sent them a published account of the sighting. He also
gave them the number of a local expert.


Jeff Wells says researchers check their facts carefully. They look
for reports that don’t match others in the surrounding area. Sometimes
an investigation turns up a trained ornithologist… and sometimes not.
But overall, Wells says the information has formed the basis for
hundreds of published studies.


That’s something that makes birders like Robert Cermak and
Georgina Doe feel proud.


“It’s nice because you’re contributing. You’re doing a
lot of hours, it uses a lot of gas, you go around a lot of blocks
but we just think it’s important.”


(sound of Georgina Doe walking)


Georgina Doe says she doesn’t really think of herself as a
scientist. But she’s out there every day, with her ear to the wind. And that’s
what the scientists are counting on.

Epa to Lift Termite Pesticide Ban?

The U.S. Environmental Protection Agency is considering
extending the use of a pesticide that the agency once decided was
not safe around children. The Great Lakes Radio Consortium’s

The U.S. Environmental Protection Agency is considering extending the use of a
pesticide that
the agency once decided was not safe around children. The Great Lakes Radio
Consortium’s
Lester Graham reports:


The pesticide Dursban is sprayed on the ground during construction to protect new
homes from
termites. Four years ago, the EPA and Dow had agreed to phase out that use of the
pesticide by
the end of this year. Exposure to children was considered risky. Now, the EPA is
reportedly
considering lifting the ban. Jay Feldman heads up the environmental group Beyond
Pesticides.
Feldman says this would be like testing the safety of Dursban on humans without their
knowledge…


“They really should stop production, then stop use, do all the studies they want to
do with full
public disclosure and then revisit the issue. Not retain the use, allow people
unknowingly to be
exposed and then obviously put children at serious risk.”


In a report in The Washington Post, a Dow spokesperson indicated using new EPA
computer modeling, Dursban now “falls within an acceptable range” of federal
guidelines.

More Warming Warnings for Wildlife

A new report on global warming forecasts more uncertainty
for North American wildlife. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:

A new report on global warming forecasts more uncertainty for North American wildlife. The
Great Lakes Radio Consortium’s Chuck Quirmbach reports:


The Wildlife Society is a group of biologists, habitat managers and educators. The society has
looked over hundreds of peer-reviewed studies from the last few years on global warming and
wildlife. The report says the one degree Fahrenheit increase in average global temperatures over
the past century is already having some effect on species like songbirds.


The Wildlife Society also says a predicted larger increase in global warming will generally push
wildlife and habitats northward. Douglas Inkley of the National Wildlife Federation says this
northward push means migration corridors will need to be expanded.


“Generally on a North-South axis, would be the best direction to put those in, so that the wildlife
are able to move as the climate changes.”


The report also urges more measures to reduce emissions of pollutants that contribute to global
warming. The Wildlife Society will take up formal policy recommendations at its meeting in
March.

State Tests People for Mercury Levels

  • While people are now aware of the health benefits of eating fish rich in omega 3 fatty acids like salmon, a study has shown that the risk of high mercury levels and heart disease might counteract those benefits. (Photo by Bartlomiej Stroinski)

Researchers in one state in the region are trying to
find out how much mercury load their residents are carrying.
So far, 300 samples have been collected for the study. And
the researchers have found that one-quarter of Wisconsin men participating in the study have high levels of mercury. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:

Researchers in one state in the region are trying to find out how much mercury load
their residents are carrying. So far, 300 samples have been collected for the study.
And the researchers have found that one-quarter of Wisconsin men participating in the
study have high levels of mercury. The
Great Lakes Radio Consortium’s Stephanie Hemphill reports:


The EPA says the safe level for mercury is one part per million. In the ongoing Wisconsin
study, one in four men and one in eight women have more than that in their bodies. The
study subjects volunteered for the study, so officials say they may not represent the
population overall.


Eating fish contaminated with mercury has long been thought to cause developmental
problems in young children. But now there’s research from Europe showing it can also
contribute to heart disease in adult men.


Lynda Knobeloch is a toxicologist with the Wisconsin Department of Health.


“There have been several studies that show that people who eat fish have less heart
disease because of omega 3 fatty acids, but the European study was able to sort out the
good effects of omega 3s from the bad effects of methyl mercury, and see that the mercury
actually can overwhelm the beneficial effects of omega 3s and actually cause heart disease.”


Wisconsin is requiring its utilities to reduce mercury emissions by 75% over ten years.

Vice Presidential Profile: John Edwards

With concerns about the economy, the war on terror and the war in Iraq, politicians have not spent a lot of time on topics such as the environment. As part of a series of profiles on the presidential and vice presidential candidates, the Great Lakes Radio Consortium’s Lester Graham reports that the candidate with the shortest record of public service is the candidate who talks the most about the environment on the campaign trail.

With concerns about the economy, the war on terror and the war in Iraq, politicians have not
spent a lot of time on topics such as the environment. As part of a series of profiles on the
presidential and vice presidential candidates, the Great Lakes Radio Consortium’s Lester Graham
reports that the candidate with the shortest record of public service is the candidate who talks
the most about the environment on the campaign trail. Heres’a look at Democratic vice presidential
candidate John Edwards:


Senator Edwards thinks the Bush campaign is vulnerable on environmental issues. When asked about
his positions on the environment, he often begins by talking about the things he feels are at risk
under Bush administration.


“Over and over and over, whether it has to do with protecting our air, protecting our water,
whether we’re going to become energy independent in this country, protecting our natural
resources, making sure that we protect our lands, our national forests – all these issues
that are so important – making sure we don’t drill in the Arctic Wildlife Refuge, all these
things are important because we have a responsibility to our children and our grandchildren
to leave this planet better than the way we found it. And that’s what we’ll do when John Kerry’s
our President.”


Although John Kerry has not spent a lot of time talking about the environment himself, Senator
Edwards knows that over 20 years in the U.S. Senate Kerry has a lifetime approval rating from the
League of Conservation Voters of 92 percent. The average Democrat has an approval rating of 70
percent… the average Republican an approval rating of 13 percent.”


Betsey Loyless is the League of Conservation Voters vice president of policy. She says
Edwards’ own record on the environment is not nearly as extensive.


“Senator Edwards has a short record on the environment because he’s been in the Senate only
one term, but his record has been, I think, has been quite good for a one-term senator. And,
he has been a leader on clean air issues. This administration, the Bush administration, had
pushed to weaken Clean Air Act standards as they apply to these old grandfathered power plants
that are the biggest of polluters. Senator Edwards led the charge to tell the Bush administration
to stop that policy on behalf of power plant operators and utilities.”


Senator Edwards did not get that job done. The Bush policy to allow power plants to make
improvements without updating pollution control equipment was put into place.


John Edwards talks about that losing battle while he’s on the campaign trail. He says he –
at least – wanted studies to see if the experts thought the changes in the regulations on the
old coal-fired power plants would affect human health.


“I mean, the laws had been there for 25 years. Can’t we take six months to figure out if you
change them what it’s going to do to people? And they refused to do it. Here’s why: they know
the answer. They know exactly. They were for it because the big energy companies are for it.
It’s just no more complicated than that. And so, that’s one example of the fight.”


Senator Edwards’ fight hasn’t been going on very long. Before his election to the U.S. Senate,
he held no legislative seat.


Jack Betts is an editorial writer and columnist for the Charlotte Observer. He’s followed
Edwards’ political career for the last few years. Betts says the environmental groups in
Edwards’ home state of North Carolina seem to approve of the senator’s positions.


“John Edwards in his Senate campaign six years ago was identified as the more likely
to be a strong advocate for the environment. And I think that helped him to election then.
And I don’t think he’s done anything to reverse those expectations about how he would stand
on the environment in the future.”


Senator Edwards’ critics say really it’s hard to say how he’d stand on any issue. They point to
his voting record for the last couple of years, noting that he was often absent. He’s missed
votes while on the road campaigning to be the Democrats’ presidential nominee… and now
campaigning as vice presidential candidate. But the environmental groups seem confident
that as vice president, John Edwards would fully support what they would expect to be a
pro-environment Kerry administration.

Study: Time Outdoors Helps Kids With Adhd

A little exposure to natural outdoor areas might go a long way toward easing the symptoms of attention deficit hyperactive disorder in kids. The Great Lakes Radio Consortium’s Tom Rogers has more:

A little exposure to natural outdoor areas might go a long way toward
easing the symptoms of attention deficit hyperactive disorder in kids.
The Great Lakes Radio Consortium’s Tom Rogers has more:


Previous studies linking the outdoors to relaxation prompted University
of Illinois researchers to survey the parents of more than 400 children
diagnosed with ADHD. The researchers asked parents to monitor
their kids’ behavior and performance after play or study periods
indoors, outdoors in an urban setting like a parking lot, and outdoors
in greener areas.


Francis Kuo co-authored the study. She says the natural settings
seemed to improve symptoms.


“This doesn’t have to be something spectacularly natural. Just getting
your kid out in a green, tree-lined street would be good, or in the
backyard, or even the neighborhood park. You don’t have to take them
to Yosemite for these benefits.”


The study didn’t make any conclusions about whether nature could take
the place of medication, but Kuo says there’s a real potential that it
could at least help kids who don’t tolerate drug treatment well. The
study appears in The American Journal of Public Health.

Concern Grows Over Flame Retardant Chemicals

A class of potentially toxic chemicals, known as PBDEs, is being found in higher levels in people in North America. The chemicals are used to prevent fires in everything from couch cushions to televisions. The Great Lakes Radio Consortium’s Mark Brush has more:

A class of potentially toxic chemicals, known as PBDE’s, is being found in
higher levels in people in North America. The chemicals are used to prevent
fires in everything from couch cushions to televisions. The Great Lakes
Radio Consortium’s Mark Brush has more:


PBDE’s are used extensively throughout North America. In Europe and Asia
the chemicals are hardly used at all for this purpose. To date, four studies have
indicated that North Americans have considerably higher levels of the
chemicals in their bodies, than do Europeans and Asians. The most recent
study tested the breast milk of 47 women in Texas.


Linda Birnbaum co-authored the study published in the journal Environmental Health
Perspectives. She says while these chemicals were created to save lives,
other chemicals should be developed that won’t be absorbed by human tissue:


“Personally I’m concerned about chemicals that persist and bio-accumulate.
They eventually get to a point be that they can be a problem.”


Some animal tests have shown that the chemicals can be toxic. That’s why the
European Union and the state of California enacted a ban on certain types of PBDE’s.
