People are beginning to notice the effects
of climate change – especially people who
get out in nature a lot. Hunters and anglers
with the National Wildlife Federation recently
released a list of some of the game and fish
species that are at risk due to climate change.
Lester Graham talked with one of the members
of the group:

Lester Graham: Kathleen Law in an angler, a member of the National Wildlife Federation, a former member of the Michigan Legislature, and a retired research scientist. First, what kind of game and fish, besides polar bears and penguins, are at risk because of climate change?

Kathleen Law: Well, everything that nests in the water or tries to have a fishery involved. It is affecting our national and our local bird, deer, the population, the habitat.

Graham: I guess that’s the question, though – how do we know that it’s not something else at work? How do we know that it’s climate change? And, of course, the skeptics will say, ‘how do we know it’s man-caused changes to the climate?’

Law: Well, we can continue being in a state of denial, and wonder where everything went, or we can get ahead. It’s not important to me who’s causing it, it’s, ‘what can I do to help?’

Graham: The US House has passed climate change legislation, the Senate is debating a version. Will the policies in those bills be enough to save some of these fish and game species you’re worried about?

Law: It’ll give us a chance. Without a concerted, willful effort, we have a very limited chance. So, there are things that we can do, that we must do, as a people who want diversity, who want to fish, who want to eat – I like venison. So what do we do to protect that resource and, and in a positive way? Which is the education and resource restoration, I think, is probably the best way to start.

Graham: Opponents of climate change legislation worry a cap-and-trade carbon reduction scheme will cost the economy too much. They don’t want the US to be put at a competitive disadvantage. Will the concerns of hunters and fishers sway any members of Congress to actually support climate legislation, if they believe it’s a jobs killer?

Law: Well, it will certainly be a consideration. The hunters and fishing folk are your constituents, they’re your neighbors, they’re your family. You can look at that, ‘it’s a job killer.’ So is climate disruption a job killer. So, how do we create new jobs? Well let’s get people out planting marsh grass. Let’s, you know, something positive. Something that people can do that makes a difference for them and their neighborhood and their community. That’s positive. That’s hope. We gotta give them hope.

Graham: What is the National Wildlife Federation doing in Washington to affect the debate about climate change?

Law: Well, they have flown in a large contingent of just people who are hunters and fishers and who have represented people in the constituencies to come in and talk to the Senators. Our hunters and fishing people – consider them sentinels. They’re out there in November, hunting ducks. They’re out in April, standing in the water, fishing. These are sentinel people, and to pay attention to what they’re saying is very important, vital, and that’s what we did in Washington DC.

Graham: Kathleen Law is a retired research scientist, a former member of the Michigan legislature, and working with the National Wildlife Federation as part of an effort to save fish and game species the group says is at risk because of climate change. Thanks very much.

Law: Thank you.

The pesticide DDT almost wiped
out the double-crested cormorant.
Now, the bird is thriving, and it’s
blamed for devouring fish in lakes,
rivers, and fish farms in many parts
of the country. Karen Kelly reports
on the struggle to share resources
with this unpopular bird:

(sound of clanking and birds)

Mike Smith eases a boat into the shallow water just off Little Murphy Island. It’s a tiny patch of sand and trees in the middle of the St. Lawrence River. It straddles the New York border with Canada.

Smith is a wildlife technician with New York’s department of environmental conservation. He specializes in cormorant management. That means he knocks down nests, breaks eggs, and – very occasionally – shoots them.

Before he even jumps off the boat, he starts counting the birds that are poking out of nests in the treetops.

“I see a few. I’m looking at their nests. We tried to have a zero percent successful reproduction rate.”

Smith counts maybe ten nests. They started with 150 or so in the spring.

There are tens of thousands of these birds. They spend their summers in the north. And in the winter, they go south where they raid fish farms.

Biologists estimate each bird eats a pound of fish a day. That can make a dent in the local fish population. The birds also strip trees of their leaves to create nests. And their guano ends up killing the trees’ root systems. That ends up driving out other animals that need vegetation.

Some people feel the birds should be eradicated. One group of anglers was even arrested for killing hundreds of them on Lake Ontario.

There are others, like the group Cormorant Defenders International. They feel they should be protected.

It’s up to biologists like Jim Farquhar of New York’s Department of Environmental Conservation to find the balance between human needs and cormorants.

Farquhar: “We have needs too, as people.”

Karen: “And we’re competing with them.”

Farquhar: “And we’re competing with them in some cases. Hopefully, if we can inject good science, we make good decisions as a result.”

The biologists’ biggest effort has been on Lake Ontario. They’ve been destroying nests there — and killing some adults – for ten years. Farquhar says they’re finally seeing results.

They’ve reduced the cormorant population on the lake by about two-thirds, and the fishing’s improved.

Now, the biologists are trying to have the same success on the St. Lawrence River. But they’ve only seen a 13% decrease in the number of cormorant nests and they’ve been doing it for four years.

Part of the challenge is that most of the birds live on Canadian soil where management is left to the landowner.

Local anglers like Steve Sharland of Ogdensburg, New York, are frustrated with the slow progress.

“They should eliminate them. They’re not a Northern New York bird and what they’re doing to our fisheries is a sin.”

That’s a common misconception. Actually, the cormorant is native to the region but few people have seen them in such large numbers.

Sharland says some people are so frustrated, they’ve been shooting the birds illegally. But Jim Farquhar believes those are isolated incidents.

“Mike just mentioned that we’ve got some black-crowned night herons nesting out here. It’s another species we’re concerned about, and one we’ve been trying to actively protect from the cormorants. So that’s a good sign.”

A good sign. But it’s another species trying to live on this small patch of land. And the biologists’ balancing act has become even more delicate.

A New Threat to Grizzly Bears

We’ve heard about a warmer climate affecting polar bears. Now, warmer weather seems to be threatening another kind of bear. Mark Brush reports on some tough times for Yellowstone’s Grizzly bears:

We’ve heard about a warmer climate affecting polar bears. Now, warmer weather seems to be threatening another kind of bear. Mark Brush reports on some tough times for Yellowstone’s Grizzly bears:

Researchers say warmer temperatures in the last ten to fifteen years have been messing with the ecology in Yellowstone National Park.

In the fall, the grizzly bears eat pine cone nuts from white bark pine trees. It gives them a lot of nutrition before they curl up for the winter. But those trees are dying.

Mountain pine beetles are killing them. The beetle populations usually get knocked back by cold weather. But it hasn’t been getting as cold. So, there are more beetles killing more trees.

Doug Peacock lives near Yellowstone and has written several books on grizzlies.

“The white bark pine trees, this is the most important grizzly food of all in Yellowstone, they are gone. And we will not see them come back in our lifetime.”

And when the trees are gone, the bears get hungry – they go looking for food – and they run into people.

48 grizzlies out of the 600 in the region were killed last year.

Some environmental groups are suing the government to get the bear back on the endangered species list.

Some States Planning Wolf Hunts

Some states plan to let people hunt wolves. Rebecca Williams reports that’s happening because the US government is taking gray wolves off the federal endangered species list in two places:

This decision means states in the western Great Lakes and several Rocky Mountain states will have control over wolves.

Some states are calling wolves a protected nongame species.

For example in Michigan, a wolf can only be killed if it’s attacking people, pets or livestock. But in other states – like Idaho and Montana – there are plans for a hunting season for wolves.

Jonathan Lovvorn is chief counsel for the Humane Society of the United States. His group and several others are planning to sue.

“Essentially what we’re worried about is that this is basically going to be a declaration of open season on animals that have been protected for decades.”

The federal decision to take wolves off the endangered species list could be overturned in court. That happened last fall.

If the decision sticks, then the Fish and Wildlife Service will be keeping an eye on wolf populations for at least the next five years.

Lead Bullets and Hunters’ Meat

  • Condors are harmed by eating meat contaminated with lead from hunters' bullets (Photo courtesy of the US Fish and Wildlife Service)

Hunters have been using lead
bullets for decades to kill game with

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.

(sound of birds outdoors)

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.

Poachers Snared by ‘Robo-Deer’

Deer hunting season is coming to an end across the region. But some people keep shooting deer despite the laws telling them not to. As the Great Lakes Radio Consortium’s Erin Syth reports, these poachers might want to pay close attention to what they’re shooting at:

Deer hunting season is coming to an end across the region, but some
people keep shooting deer despite the laws telling them not to. As the
Great Lakes Radio Consortium’s Erin Syth reports, these poachers might
want to pay close attention to what they’re shooting at:


Wildlife officials throughout the region are using robotic deer to catch
poachers. The deer’s head and tail move by remote control. When a
hunter attempts to shoot the deer, wildlife officials move in.


Robo-deer are made from polyurethane foam and real hide. The latest
version is known as the “Stomper.” It retails for 17-hundred dollars, and
comes standard with a stomping front leg.


Brian Wolslegel is owner of Custom Robotic Wildlife, Incorporated. He
says these deer definitely work.


“Some guy was telling me about a guy that shot a decoy. They took his
gun, fined him – I think it was $2,000 and moved their operation a mile down
the road, and two hours later the same guy came back and shot at it again with
a different gun.”


Conservation officials in Wisconsin report that one robo-deer can rack up
to 30-thousand dollars in collected fines for the state.

Cormorant-Killing Policy Ruffles Feathers

Across the Great Lakes region, the recovery of the cormorant
is booming. But some anglers and resort owners think the cormorants are eating too many of the fish that people like to eat. In some areas, wildlife managers have resorted to killing cormorants on popular fishing lakes. In one case, critics say there’s not enough evidence to justify the killing. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:

Across the Great Lakes region the recovery of the cormorant is booming. But some anglers and resort owners think the cormorants are eating too many of the fish that people like to eat. In some areas, wildlife managers have resorted to killing cormorants on popular fishing lakes. In one case, critics say there’s not enough evidence to justify the killing. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:


Larry Jacobson is the third generation in his family to run the Hiawatha Beach Resort on Leech Lake, about two hundred miles north of Minneapolis. Three years ago, on fishing opener weekend, all of his twenty-one cabins were full. This year, he had no guests. Jacobson says the word has spread that fishing is down on Leech Lake. He blames the cormorants. The birds nest on a small island in the south end of the lake. Eight years ago, there were fifty nests; last year, there were two thousand five hundred.


“The cormorants eat about a pound fish a day. The way the population was just exploding out there, you could see writing was on the wall, that this was really going to make dramatic impact.”


Jacobson says his guests are still catching big walleye, but the smaller, pan-sized walleye are getting hard to find.


There are several reasons why the walleye population might be down, but Jacobson and other business owners blame it on the cormorants, and they’ve asked the Department of Natural Resources to do something about the birds.


“Leech needs to be maintained as high quality fishery. There’s such an economic impact to the area from walleyes, that if you don’t maintain it that way, everyone’s going to be suffering.”


(Sound of boat motor)


Resource officials are responding to the resort owners’ concerns. The Leech Lake Band of Ojibwe owns the island. John Ringle is wildlife manager for the tribe.


“Okay we’re headed right at Little Pelican Island right now.”


Little Pelican Island is about three acres of sand and scruffy shrubs. Hundreds of cormorants cover the shore. Ringle says they fish out here in the open waters of Leech Lake.


“They’re omnivorous so they’re eating all sorts of different varieties of fish. Right now they’re probably eating large numbers of perch.”


Ringle is working with state and federal agencies to reduce the number of cormorants nesting here, eating fish, and crowding out other birds, such as the endangered common tern.


Normally, cormorants are a federally protected bird, just like eagles. That’s because they were almost wiped out by the insecticide DDT before it was banned in 1973. But a new rule allows resource officials to harass and even kill cormorants where they’re damaging other wildlife.


This summer, workers are sitting in hunting blinds on Little Pelican Island, shooting cormorants. They use air rifles to make as little noise as possible, so the other cormorants aren’t spooked away.


So far, they’ve killed more than two thousand birds. They plan to leave about five hundred nesting pairs alive. Ringle says nobody’s happy about shooting cormorants, but he says he thinks it’s necessary.


RINGLE: “My philosophy is that as mankind utilizes the resource, we have to manage them, we’re not in finite supply.”


HEMPHILL: “Do you think we know enough to manage them?”


RINGLE: “Not really. I think the public is demanding action prior to any conclusive study being conducted.”


And that’s a big problem for Francie Cuthbert. She’s a professor and cormorant researcher at the University of Minnesota. Cuthbert says the agencies that want to cut down the cormorant population skipped an important part of the management process: finding out what’s actually happening on Leech Lake.


“They’re really being driven by complaints from citizens and resort owners who are concerned about local economics, and who just don’t like the birds; they’re afraid of the numbers. If we responded to all natural resources conflicts this way, we’d be in a state of chaos.”


Cuthbert says even with the cormorants’ dramatic comeback since the days of DDT, there still aren’t as many as there were a hundred years ago. She says rather than kill cormorants, wildlife officials should try to boost the number of fish.


The state of Minnesota is working on that. It’s stocking Leech Lake with walleye for the first time this year. Conservation officials are studying some of the birds they killed to find out what they’re eating. And the state is also limiting what size of walleye anglers can catch so the fish can recover.


That makes resort owners like Larry Jacobson nervous, because he says a lot of anglers don’t like the limits. But at least he’s glad someone’s doing something.


“The fishery is a business, there’s no question about that. If you want to sustain our economy in this area, you’ve got to manage the lake.”


Workers will continue shooting cormorants occasionally through the summer. And the control effort could continue. Experts say it’ll take several years for the fish to recover enough to draw anglers back to the lake.

Cities Take Aim at Roosting Crows

  • Crows are roosting in huge groups in cities all over the country. The USDA is trying to find ways to get them to go back to their natural habitat. (Photo by Paige Foster)

Flocks of crows are nothing new in most cities. In the fall and winter months, crows forage for food during the day and roost in city trees at night.

Flocks of crows are nothing new in most cities. In the fall and winter months, crows forage for food during the day and roost in city trees at night. The birds like cities because they’re safe and comfortable. The residents generally don’t like the crows, though. The Great Lakes Radio Consortium’s Skye Rohde reports:


(sound of crows)


There are a lot of crows here. About 63,000 of them are in the city. The trees are thick with them. At dawn and dusk, so is the sky. Bird feces coats city sidewalks and parked cars. Amy Emedon lives in town. She’s used to the crows.


“They make a lot of noise at night, or in the morning they kind of wake you up. But other than that, they don’t really bother me that much. They’re kind of gross, because their poop’s all over the place and they’re so loud and there’s so many of them. Like sometimes you can’t even see, like, the sky. It reminds me of that movie ‘The Birds.'”


Crows have been wintering in Auburn, New York for more than 100 years. Written records from as early as 1911 describe a very large roost downtown. Auburn has the largest crow roost in the state. This winter, city officials hired the U.S. Department of Agriculture to haze the crows.


(sound of distress calls and pyrotechnics)


Hazing means the eight USDA scientists drive around town using recorded crow distress calls, pyrotechnics and laser pointers – anything that will upset the birds and drive them out. Sometimes this includes shooting the birds, but not in New York state. Richard Chipman is the New York state director of the USDA’s wildlife services project. He says the idea is to move the birds to a more “natural” habitat.


“The goal is not to just relocate these birds and cause somebody else problems. The goal is to try to relocate them to a low-impact area to improve the quality of life of folks here in the city.”


The only problem with this plan is that the crows really like being in cities. The birds are smart. They’re communal. They recognize that they’re safer downtown than out-of-town. Kevin Mcgowan is an ornithologist at Cornell University who has studied crows for 16 years. He’s heard of large crow roosts in cities across the nation, ranging from 100 birds to two million. Mcgowan says it’s usually warmer in cities. Crows like that. And they like the big trees and streetlights.


“I think the lights is a big deal. Crows are scared of things that go bump in the night because those things eat them. And that’s pretty much great horned owls, okay? Great horned owl is probably the single scariest thing to a crow, because they come in at night when crows can’t see and owls can. And owls eat a lot of crows.”


Mcgowan says crows started settling in U.S. cities in much larger numbers in the 1970s and 1980s, after a change to the Federal Migratory Bird Treaty Act.


“In – I believe it was 1972 – there was an amendment to the act that afforded crows protection for the first time. What that meant was now you couldn’t just shoot crows anytime you wanted to. You had to do it under the direction of a state hunting season, which had regulations.”


As a result, people changed their behavior. They didn’t shoot crows as much, so the crows became less scared of them and moved closer. In other words, crows have realized that cities are safer habitats than their “natural” environment. Mcgowan says he’s seen it before.


“You have a big predator that scares away the smaller predator that’s the one that really bothers you, then it behooves you to hang around the big predator. Happens all the time around people. There are lots of things that come in to be around people because they’re relatively safe there.”


Whether the USDA can break that pattern in cities like Auburn remains to be seen. Scientists have surveyed this city and harrassed the remaining crows. But they might have to return next winter to do the same thing again. And Auburn officials, like those in other crow-filled cities, might need to consider changing those things that attract crows in the first place, rather than just focusing on scaring the birds away.

Timber Wolves Moving Into New Area

  • Timber wolves have been making a comeback in the Midwest for some time. Recently, they've been reappearing in places they haven't been seen in decades.

Timber wolves are moving into an area where they

Timber wolves are moving into an area where they haven’t been seen for about 80 years. The Great Lakes Radio Consortium’s Lester Graham reports:


Timber wolves have been repopulating areas of Minnesota, Wisconsin, and the upper peninsula of Michigan for some time now. But recently, a wolf was shot and killed in the lower peninsula of Michigan. Since then, tracks of two more wolves have been identified not too far away from the shooting. The two peninsulas of Michigan are separated by water five miles across the connect Lake Michigan to Lake Huron. Sometimes, it freezes over. Michigan Department of Natural Resources biologists figure a small pack of wolves made the trek across the ice. Brian Roell is with the DNR.


“Well, it’s interesting that, you know, wolves are, you know, repopulating areas that, you know, they’ve been removed from. It’s really nice to see that these wolves are making their own comeback.”


Hunters are warned to be careful when trapping or hunting. The wolves are still federally protected. The wolf shooting this fall was ruled accidental because the trapper shot the animal thinking it was a coyote, since wolves were killed off in the area decades ago.

Mourning Dove Protected as Peace Symbol?

About half the states around the Midwest allow hunters to shoot mourning doves. But one state that had hoped to begin a hunt this fall won’t be doning so. The Great Lakes Radio
Consortium’s Chuck Quirmbach Reports.


In Wisconsin, a record number of hunters turned out at public meetings last year and voted for a shooting season on mourning doves. The season was supposed to start this September, but a judge has issued a temporary injunction against the hunt.
He’s ruled that during the Vietnam War era, Wisconsin lawmakers may have taken the mourning dove off the list of regulated game birds, when they made the dove Wisconsin’s official symbol of peace. But Jim Weix of the Wisconsin Dove Hunters Association, says this year, lawmakers reversed themselves and checked over a proposed rule allowing the dove hunt.


“They decided to let it stand, so I do disagree with the judge of course.”


A final court ruling is not expected prior to October 30th, which is when this year’s mourning dove hunt was scheduled to end. For the Great Lakes Radio Consortium, I’m Chuck Quirmbach in Milwaukee.
