Study: Lawn Chemicals to Blame for Bird Deaths

Lawn pesticides are killing a lot more than grubs and weeds, according to the National Audubon
Society. They want to let people know that if they use the chemicals, they are unintentionally
killing birds. And they’re possibly putting their families at the same risk. For the Great Lakes
Radio Consortium, Joyce Kryszak has more on the educational campaign:


People throughout the region have been scooping up dead bird corpses and sending them off for
testing since the West Nile Virus first hit. But research shows West Nile is usually not to blame.
Studies done on about eighty thousand dead birds found in New York state showed aesthetic
lawn care products were the leading killers.


William Cooke is a regional coordinator for the Audubon Society. He says the toxins from these
common product rivals the chemicals used on golf courses and farms.


“We’re going to have our kids play on this, we’re going to have the dog play on this, and then come
into the house? People are not connecting between the pesticides they put down and the impacts.
And we’re doing this for a green lawn?”


Cooke says the national educational campaign hopes to alert more than a million people to the
dangers of pesticide use. It will also tell people how to find and use organic alternatives to
maintain a healthy lawn and environment.

Government to Be Sued Over West Nile Virus?

Dozens of Canadians afflicted with the West Nile virus will be meeting this month to decide whether or not to launch a class action lawsuit against the Ontario government. A Toronto lawyer says he has as many as 100 clients who want to sue the Ontario government for not presenting all the facts about the risk of the disease. They alleged that public health officials didn’t do enough to protect them from the disease. The Great Lakes Radio Consortium’s Dan Karpenchuk reports from Toronto:

Dozens of Canadians afflicted with the West Nile virus will be meeting this month to decide
whether or not to launch a class action lawsuit against the Ontario government. A Toronto
lawyer says he has as many as one hundred clients who want to sue the Ontario government for
not presenting all the facts about the risk of the disease. They alleged that public health officials
didn’t do enough to protect them from the disease. Dan Karpenchuk reports from Toronto:


Official Ontario government statistics show there were 374 West Nile cases in the province last
year. But health experts say the number was closer to one thousand. And many of those experts
say the Ontario government played down the threat, keeping critical information out of the public
domain.


Dr. Colin D’Cunha is Ontario’s medical officer of health. D’Cunha has said that the growing
alarm has been driven by hype rather than by facts:


“And I have to remind people that the serious signs and symptoms are seen in less than one per
cent of people who come down with West Nile Virus infection. And to put it in context,
remember that the flu kills about nineteen hundred Canadians each year.”


The lawyer who may bring the suit, says most people were led to believe that the virus would
affect only the sick and the elderly, which has not been the case.


National health officials are now warning that the virus will hit earlier and harder than last year,
and spread across the entire country.

Birders’ Passion Helps Scientists

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.

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 so it’s
hard to get a sense of
its mass…”


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 actually 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 become 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 doing this
kind of count
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.

Enviros Push to Ban Wood Preservatives

Some environmental groups and labor unions are pushing for an end to using certain wood preservatives in treated lumber.

Some environmental groups and labor unions are pushing for an end to using certain wood
preservatives in treated lumber. They’ve jointly filed a lawsuit in federal court to push the
Environmental Protection Agency to stop the use of the preservatives because they contain toxic
chemicals. The Great Lakes Radio Consortium’s Lester Graham reports:


The EPA acknowledges that some of the wood preservatives such as penta and creosote contain
chemicals that can cause cancer. But, the agency has long maintained that it cannot just ban the
wood preservatives used to treat lumber, utility poles and railroad ties. That’s because it says
there are no viable alternatives. Jay Feldman is with the environmental group “Beyond
Pesticides” which is one of the organizations suing the EPA. Feldman says the EPA position used to be true,
but not anymore:


“The alternatives are on line; they’re ready to go. It’s unnecessary for us to continue to dump
over a billion pounds of these wood preservatives into the environment on an annual basis.”


Feldman argues that recycled rubber, steel and plastic materials are available at about the same
cost. And he adds many power, telephone and cable lines can be put underground rather than on
creosote-treated utility poles. The Treated Wood Council indicates that its products are safe, but the industry is
beginning to offer different preservatives without the cancer-causing chemicals because of the
concerns.

Bird-Feeding Necessary This Winter?

Some bird enthusiast clubs around the Midwest – Great Lakes Region are calling on their
members to put out extra bird feeders this winter. But as the Great Lakes Radio Consortium’s
Jonathan Ahl reports, the move might not be necessary:


Some of the clubs say birds are still suffering the effects of the West Nile Virus and need extra
food this winter to make sure they are healthy in the Spring. But not all scientists agree with that
claim. Barbara Frase is a biology professor at Bradley University in Peoria, Illinois. She says
there are only a few circumstances where birds need the extra food humans provide:


“In the winter, if there is a really long cold spell, then the birds are probably helped. The extra
food will help see them through that cold snap. Otherwise, it probably doesn’t add to their
survival ability.”


Frase says studies show birds that frequent bird feeders still get eighty percent of their food from
the wild. She says it is still a nice thing to help birds, but says the West Nile Virus is really not a
reason to put out an extra feeder this winter.

More Disease With Climate Change?

A recent report looked at the potential health effects of climate change on people in the Niagara region. The report predicts increased exposure to malaria, dengue fever and yellow fever in coming years. The report was released by the environmental group Pollution Probe, and was done in partnership with the health and environment departments of the Canadian government. The Great Lakes Radio Consortium’s Dan Karpenchuk reports:

A recent report says people in the Niagara region expect increased exposure to malaria, dengue fever and yellow fever in coming years because of climate change. The warning is contained in a new report by the environmental group, Pollution Probe. The report was done in partnership with the health and environment departments of the Canadian government. The Great Lakes Radio Consortium’s Dan Karpenchuk reports from Toronto:


The report says the diseases are projected to spread because climate change favors the northward movement of disease carrying birds, insects and rodents. Quentin Chiotti of Pollution Probe says the sudden spread of the West Nile Virus is an example of what to expect.


“Now though, there’s some uncertainty about predicting just when that will happen, without a
doubt the conditions are going to be ripe for these kinds of disease outbreaks.”


Chiotti says there are already twenty confirmed cases of the West Nile Virus in Canada, compared
to none last year. And more than three thousand in the U.S.


Chiotti also says the number of excessive heat days could double to thirty each summer by the
year 2030. He says that could lead to more deaths – as many as four hundred people each
summer in the region.


Pollution Probe says the predictions show the need to tackle greenhouse gas emissions as soon as
possible.

Doctors Urge Kyoto Sign-On

Some physicians are concerned about the United States not attending the final talks on the Kyoto Protocol on global warming held in early November. The physicians say global warming is already a problem and is adding to a number of public health threats. The Great Lakes Radio Consortium’s Lester Graham reports.


Some physicians believe the increase in infectious disease outbreaks such as West Nile virus, Lyme disease, and Hantavirus are connected to global warming. They say the warming already seen contributes to the spread of the viruses. The warming also could be causing more volatile weather –such as sudden storms in some parts of the Great Lakes region. That can cause flooding of sewer systems that lead to illnesses. Bob Musil is the Executive Director of Physicians for Social Responsibility. He says the group is encouraging politicians to upgrade sewer systems to cope with the changes.


“There are sudden storm surges, sudden precipitation leads to flooding in combined sewage and storm drains. In the state of Michigan in our report we discussed this problem. And we actually, as physicians, go and talk to the responsible officials.”


But the physician’s group says adapting to the changes only treats the symptoms. Musil says the long-term problem can only be dealt with by reducing air pollutants that cause global warming, something the group says the U-S is refusing to do right now.

West Nile Virus Marches West

  • Zoos have helped public health officials monitor the spread of the West Nile virus. Besides concerns about human health, zoos are worried about the birds in their care.

Cooler weather sweeping the Great Lakes region means the end of the mosquito season. It also means a temporary halt to the spread of West Nile virus in the area. But this past summer the virus made headway into the region much faster than experts had expected. The Great Lakes Radio Consortium’s Lester Graham reports:

Cooler weather sweeping the Great Lakes region means the end of the mosquito season. It also means a temporary halt to the spread of West Nile virus in the area. But, this past summer the virus made headway into the region much faster than experts had expected. The Great Lakes Radio Consortium’s Lester Graham reports.


It’s extremely rare that West Nile virus causes severe illness in humans. But it does happen. While most people won’t even realize they’re infected, about one fourth of those infected will exhibit some mild symptoms. However, the virus can cause encephalitis, which is an inflammation of the brain. In very rare cases it can be fatal.


Zoos have been helpful in monitoring the spread of the disease. It was first identified here in the U.S. by the Bronx zoo in the fall of 1999 after crows started dying in the New York area. Since then, zoos across the U-S have kept watch on their birds and animals. In part to protect them and in part to help health officials track the progress of the virus.


Scientists thought the virus would slowly make its way to neighboring states. But, it’s spread much more quickly than expected. It wasn’t supposed to hit states as far west as Illinois and Wisconsin until sometime next year. But it made it even farther west with reports of it in Missouri.


Researchers have learned the virus is carried by birds such as crows, blue jays, hawks and Canada geese. Dominic Travis is a veterinary epidemiologist at the Lincoln Park Zoo in Chicago. He says since West Nile virus infects birds, experts suggested it would spread southward from New York. That’s because many birds, including some infected with the virus would travel south for the winter. Others, though, said it could spread west.


“And, the westward race won. We were fairly surprised that it came past the Michigan and western Ohio area, but we’ve been prepared because we started this surveillance system and started working with the CDC and USDA and everybody last spring for this specific eventuality.”


Travis says zoos across the Midwest started monitoring for West Nile virus this past spring. They worked with local health officials to determine if the disease had spread to birds in the area.


While birds carry the disease, mosquitoes spread it. So, officials at he Lincoln Park Zoo have been trapping mosquitoes and drawing blood from its animals, testing for West Nile virus. They’ve also been working to reduce the chance that animals will be bitten by mosquitoes. Again. Dominic Travis.


“The two strategies are try and limit the mosquito and if you can’t limit the mosquito, limit the contact.”


Most zoos are hesitant to use insecticides to kill the mosquitoes. So, instead, they try to eliminate places where they can breed. Basically, that’s anywhere a puddle of water stands for more than four days. Travis says that helps meet strategy number one, limiting the mosquito.


“So, a) if you don’t have mosquitoes, the risk is fairly low, and b) if you can’t get rid of all your mosquitoes, then you want to stop mosquitoes from biting the animals and so you do things to keep them separate. And those are –depending on the birds, the size, the situation, the zoo– those are keeping them in during mosquito feeding hours or some people have mosquito nets that they’re incorporating and so on and so forth.”


Zoos are especially worried because they’re responsible for some very rare birds, in some cases the last of a species.


At the Saint Louis Zoo, a huge outdoor flight cage and several other outdoor cages make up the zoo’s bird garden. Zookeeper Frank Fischer says outside bird exhibits are at highest risk.


“We’re making sure that, trying to make sure that none of our birds, even the birds in the outside exhibits here in the bird garden don’t contract any of that disease, say, from crows or our blue jays or birds of that type.”


While birds are most at risk of infection, they’re not the only species hit by the virus. In the U.S., as many as a dozen people have died after being bitten by a mosquito carrying West Nile virus. And even more horses have died. People and horses are considered incidental victims. That is, they don’t carry the disease and they don’t spread it. But they can be infected. A veterinarian in southwestern Illinois, Don Van Walleghen, says he’s gotten a lot of calls from worried customers, asking about West Nile virus.


“Basically, they want to know, is it here? Is it a concern for me?”


And because it’s such a recent phenomenon Van Walleghen’s customers have a lot of other questions. They bring in dead birds, wondering if their dog or cat that was playing with the bird might be infected. So far, aside from horses and people, there have been no reports of other animals, livestock or pets, being infected by West Nile virus, or spreading it.


“In humans, if you are a human bitten by a mosquito that had this disease, you could not transmit it to your kids or to anything else. So, at least that limits the disease from even being thought of as any kind of epidemic.”


But it is spreading. Experts hope that weather conditions next year are not good for mosquito production. But even a relatively normal to dry season as this past year was has not seemed to slow the spread of West Nile virus. If next year is wetter, experts say the virus could spread farther and infection rates could rise. That’s why health and agriculture experts are reminding people to work toward reducing the mosquito population next year. They recommend everything from keeping roof gutters unclogged to prevent standing water, to landscaping yards and driveways to eliminate puddles. Anything that will slow mosquito production next year will hopefully slow the spread of the West Nile virus. For the Great Lakes Radio Consortium, this is Lester Graham.

New Vaccine for West Nile Virus?

Researchers might soon have a vaccine to protect birds from the West Nile virus. The Great Lakes Radio Consortium’s Lester Graham reports:

Researchers might soon have a vaccine to protect birds from the West Nile virus. The Great Lakes Radio Consortium’s Lester Graham reports.


The centers for disease control and the U.S. Army are getting help to develop a vaccine for prevention of the mosquito borne West Nile virus. Here in the U.S. in the past couple of years, the virus has been responsible for the deaths of thousands of birds from more than seventy species. Michael Hutchins is with the American Zoo and Aquarium Association. He says research into a vaccine ahs been driven by the need to protect birds in zoos.


“The current studies are to develop an injectable vaccine, but the intention is to try to take that and develop an ingestible variety that could be spread on bird feed and would therefore have a hopefully-big impact on wild birds as well.”


Chicago’s Brookfield Zoo, the Walt Disney Foundation, the Wildlife Conservation Society and the American Bird Conservancy have all contributed to the project. Hutchins says a vaccine could be developed as soon as the next month or so. For the Great Lakes Radio Consortium, this is Lester Graham.
