There’s one American bird that has an unusual habitat problem. Chimney Swifts have adapted in the past as humans encroached on their territory. But now changes in human behavior are presenting new problems for the birds. And some people are trying to help them adapt again. Stephanie Hemphill reports.

In his dad’s window-and-door warehouse in the Minneapolis suburbs, Derek Meyer is supervising the boys in his scout troop as they build a wooden tower for Chimney Swifts.

They’re using rough plywood to build a narrow box twelve feet high with an opening about a foot square.

Derek is doing this project to earn the rank of Eagle Scout. In the process, he’s learned a few things about the lives of Chimney Swifts.

“They originally lived in hollow trees but when the settlers from Europe came over they started destroying the trees, so they decided to live in the chimneys, and then people started putting wire over their chimneys, so over the last 40 years they’ve lost half of their population.”

Not just wire, but rain caps and other devices to keep moisture and critters out of chimneys.

The new home these boys are building for Chimney Swifts is destined for the nature center next to a nearby school. The school district was planning to tear down an old brick chimney as part of a remodeling project. Rebecca Field found out about that, and she tried to stop it.

“I said, wait a minute, I’m sure there are Chimney Swifts in there and they’re really good birds because they eat about 2,000 insects a day, each of those birds. And their favorite insect is the mosquito.'”

Field is on the board of Audubon Minnesota, and she’d been watching the swifts hanging around the chimney in the evenings. Individually they look like fat cigars with wings, but when they get ready to swoop down into the chimney for the night, there are so many of them, they look like a funnel cloud.

“How they communicate I have no idea, how they put the brakes on when they dive into that chimney so quickly, it’s a mystery but it’s a fun thing to watch.”

In the end the school district decided to leave the chimney up.

So now, a few weeks later, and just in time for the Chimney Swifts to fly back up from the Amazon, the tower is standing on a concrete pad at the school’s nature center.

School naturalist Marleane Callaghan has already brought all her classes, grades three-through-five, to check it out.

“We’ve talked about the bird, what it looks like, the dimension of it, I’ve invited them to come back with their parents to watch in the school parking lot in the evening up at the high school where they’ve left the chimney, and then to walk on down, to be able to identify them.”

This project is part of an effort by Audubon groups all over the country to raise awareness of Chimney Swifts and their need for homes.

In Minnesota, project director Ron Windingstad wants to convince homeowners to make existing chimneys more welcoming. He says people can take the caps off their chimneys during the summer, or just raise them high enough so the birds can fly in from the sides.

Soon these school kids will be able to see the amazing acrobatics of the Chimney Swifts. Windingstad says they hardly ever stop flying, from morning til night. They’ll even sip water and take a bath in a nearby pond, without stopping.

“They’ll scoop down, lower their bill, and fly across it and drink in the water. They’ll use some of these shrubs around here to break off little twigs about the size of a wooden matchstick or toothpick actually, and use that to build their nests, and they do that while flying as well. They are marvelous creatures.”

The American bald eagle is the Endangered Species Act’s poster child, it’s Come-back
kid. This time of year, a lot of towns organize eagle watches to celebrate the success
story and to attract tourists. Reporter Shawn Allee couldn’t resist visiting one:

I wasn’t exactly sure where to spot eagles in Dubuque, Iowa, so for the annual Eagle Watch, I
started indoors – at the city’s convention center.

There were plenty of eagle-related knick-knacks for sale – like eagle bobble-heads, plush toys,
and photos.

But locals there told me where to find eagles, and why the Eagle Watch means so much.

“Twenty years ago, we read about eagles, we heard about eagles but we never ever saw
one.”

That’s Dubuque photographer, Robert Eichman.

Eichman: “I’ve been taking pictures for 65 years. I probably never got a picture of an eagle
until about 7 or 8 years ago, so I have witnessed their comeback.”

Allee: “So, now this is one of their hotspots.”

Eichman: “Right. This time of year, there may be four- to five-hundred eagles roosting on
the bluffs on either side of the river.”

Eichman said the best place to see them is on the Mississippi River. There’s a dam that stops the
river – and a lock that let’s boats through. He suggested I try the Eagle Watch trolley.

Allee: “Hi there. Are you going to the lock?”

Driver: “Yeah.”

Allee: “Great.”

Dubuque’s had an Eagle Watch event for twenty one years, but dozens of towns in the
upper Midwest sponsor them in January and February.

Eagles were declared endangered in the early seventies because a pesticide was killing their
young. They’re now off the federal endangered and threatened list.

Seeing an eagle is still novel enough that there’s a small tourist industry built around their winter
hunting grounds.

Driver: “Right up here to the left folks, there are four, five, six right in a row.”

Allee: “There they are. It’s amazing. I’ll get out here.”

I’d seen a few eagles before but never this many at once; they were in trees and swooping over
the river. I headed to a lookout run by the army corps of engineers.

Park ranger Bret Streckwald was there to answer questions.

Allee: “Why is it this is such a good location to see bald eagles in the winter time?”

Streckwald: “Well, it’s the lock and dam, and they’re primary food is fish.”

Allee: “So, on our left, it’s solid ice on the Mississippi River, then what do we see on the
right?”

Streckwald: “Open water. The dam keeps the water open and the fish go through the dam
and they’re stunned a little bit, and it makes it pretty easy for the eagles to feed on them.”

Allee: “Hardly seems fair, but it keeps the eagles pretty healthy.”

Streckwald: “Yeah, they’re all pretty well-fed.”

Allee: “So what do you have set up here?”

Streckwald: “We have some spotting scopes set up on the various eagles that are stationary
and obviously we have the birds that are flying. We have a lot of people that like to take
pictures.”

Allee: “I don’t know how good this shot is going to be with my very amateurish camera,
but…”

Boy: “Dad – I saw one in the telescope. I saw one in the telescope flying! Whoa … ahuh.”

Allee: “I think this boy had the right idea, I’m now looking through one of these telescopes
the army corps of engineers set up for us. And I can see this eagle perfectly. The ice is
bobbing up and down, and he’s going with it. He’s staring out on the water, steely-eyed. It’s
a nice image.”

Life After a Forest Fire

  • Biologist find signs of regeneration shortly after a forest fire. (Photo courtesy of Stephanie Hemphill)

Forest fires capture a lot of attention and concern. Loggers worry about lost resources. People who hike and camp in the forest worry they’ll see nothing but ugly, blackened vistas for years to come. But a big fire this summer in the northwoods gives people a chance to see just how fast the forest can recover. Even as the fire still burns, foresters see signs of life.

Forest fires capture a lot of attention and concern. Loggers worry about lost resources.
People who hike and camp in the forest worry they’ll see nothing but ugly, blackened vistas for years
to come. But a big fire this summer in the northwoods gives people a chance to see just
how fast the forest can recover. Even as the fire still burns, foresters see signs of life.
The GLRC’s Stephanie Hemphill reports:


The Cavity Lake fire started in mid-July this summer. It turned out to be the fire people have been
worrying about for seven years. In 1999, huge straight-line winds knocked down millions
of trees. They toppled into an impassable tangle of drying fuel in and near the Boundary
Waters Canoe Area Wilderness in northeastern Minnesota. Locals call it “the
blowdown.”


The Cavity Lake fire gobbled up the blown-down trees. It roared across lakes,
threatening homes and resorts.


(Sound of boat motor)


Two forest service workers hop in a small boat to document the fire and its aftermath. In
places, the fire seems to have consumed everything, down to the soil, but these two are
looking for life.


Black, powdery ash covers the ground. Burned snags, limbless trees the color of
charcoal, stand against the sky. But even here, biologist Lissa Grover can find signs of
life.


“If you look around, you can see the 20-foot tall trees that took off after the blowdown,
and a lot of them still have cones on the top, and those cones are open now, and the seeds
will fall from them into the bare soil and germinate.”


In fact, some seeds, such as Jack Pine, wait for fire to open:


“There’s a seed bank in the soil, just waiting for a disturbance like this. There’s one plant
called Bicknell’s geranium that sprouts after fire, produces flowers the second year, sets
seed. Those seeds will stay in the soil until the next fire, even if it’s 200 years from now.”


And some plants aren’t waiting for the next generation. Grasses are already pushing
green shoots through the blackened dirt.


(Sound of motor)


Our next stop is a big island. After the 1999 blowdown in northeastern Minnesota, the
Forest Service purposely burned some areas near homes and resorts. The idea was to
reduce the amount of fuel available for wildfires. Crews set this island on fire four years
ago.


Wilderness ranger Tim McKenzie says that intentional burn saved the island, and the
resorts, from the Cavity Lake fire:


“It was traveling pretty good distances and spotting on these islands. As soon as it hit
here it just lay down.”


The blowdown fuel was already burned, and the young trees were too small and green to
keep the fire going.


Animals here are also adapted to fires. Bears, wolves and moose can walk away from a
fire. Birds can fly away or take refuge in the water.


Grover does worry about the young eagles, still in their nests and unable to fly.


“The trees are still there, the nest is still there, the adult eagles are still here, but it’s
unlikely that the juveniles in the nest survived the fire.”


But a few minutes later, we hear a sound that gladdens Grover’s heart: a young eagle
screaming for food.


(Sound of eagle)


At least one young eagle survived the Cavity Lake fire.


This land has been swept repeatedly by fires. They start, grow, move, and burn out in a
patchwork pattern. A fire last year burned until it ran into an area that had burned thirty
years ago. And here, in a thirty-year-old burn, is a picture-perfect Boundary Waters
portage.


(Sound of walking)


Young balsams scent the air with their clean, northwoods smell. Young birches lean
across the path. The moss is soft underfoot. The air is moist, and the mosquitoes are
buzzing.


Tim McKenzie fought that fire, thirty years ago. He says whenever fire burns, it’s nature
at work:


“People are used to seeing a snapshot in time. But the landscape that they’re used to
seeing became that landscape because of this process.”


And canoe outfitters here are busy planning routes that will show that landscape changing.

The Costs of Eagle Poaching

Eagles have long been treasured as a national symbol, but the bird is also prized by poachers. Pow-wow dancers, New Age shamans, and European trophy collectors are paying top dollar on the black market for eagle parts. The Great Lakes Radio Consortium’s Brian Bull reports:


Eagle heads, feet, wings, and feathers are prized for costumes, artwork, and ceremonies. Some collectors are paying roughly a thousand dollars for a golden or bald eagle carcass.


Mary Jane Lavin is a special agent with the U.S. Fish and Wildlife Service. She says the birds are protected by the Bald and Golden Eagle Protection Act. Violators can land up to a year in jail and
pay a $100,000 penalty.


Lavin says a better way to get eagle parts is through a federal repository program. The program sends out carcasses and parts from eagles that have died in the wilderness or in zoos.


“The demand is greater than the supply, and there is a waiting list but we’re doing our best to make sure that we can provide those things, that were acquired and died naturally so that
people don’t have to feel that they need to go out and shoot eagles.”


Special permits for possessing and gathering feathers can also be given to those with government-issued Certificates of Indian Birth.

Cormorant-Killing Policy Ruffles Feathers

  • Cormorant populations have risen exponentially from their previously dismal numbers. (Photo courtesy of the NOAA)

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.

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.

States Ready for Wolf Delisting?

The U.S. Fish and Wildlife Service wants to remove the eastern population
of the gray wolf from the Endangered Species List and turn over wolf management
to state control. But not everyone thinks the states are up for it. The Great Lakes Radio
Consortium’s Katherine Glover has the story:


(sound of wolves howling)


The image of the wolf has always had a powerful effect on people. Wolves seem dangerous,
mysterious, romantic. They are a symbol of the untamed wilderness. Before Europeans came
to America, wolves roamed freely on every part of the continent. In 1630, the colony of
Massachussetts Bay started paying bounties to settlers for killing wolves. Over the next
300 years, wolf killing spread across the country, until all that was left was a few small
pockets of surviving wolf packs.


When the Endangered Species Act passed in 1973, the only wolves left to protect in the
Midwest were in Northern Minnesota. By some estimates, there were as few as 350 of them.


Today, Minnesota has a healthy wolf population of around 2400 animals, and smaller populations
are growing in Wisconsin and Michigan. Becaue of this success, the U.S. Fish and Wildlife Service
has proposed removing the animals from the Endangered Species List. This would mean wolves would
no longer be federally protected – it would be up to the states.


(sound of gate opening)


Peggy Callagan works with captive wolves at the Wildlife Science Center in Minnesota. She’s the
Center’s co-founder and executive director. She and her staff research ways to minimize
conflicts between wolves and people. Callahan is looking forward to seeing the wolf taken off
the Endangered Species List.


“It’s a good thing for the Endangered Species Act, to take a wolf off or an eagle off or a
peregrine off when it has recovered. The act was not established to provide a permanent
hiding place. It was established to protect a species until such time that they could be
managed in a different way.”


Wisconsin and Michigan have wolves because young born in Minnesota have migrated east to start
their own packs. Callahan says how Minnesota manages its wolves will affect wolf numbers in the
Midwest. And she isn’t crazy about Minnesota’s current wolf management plan, which has different
rules for different parts of the state.


“Now, there’s a boundary; there’s a boundary called a wolf zone, and there’s a boundary that’s
called the ag zone. And nobody likes it. We went backward.”


In Northeastern Minnesota, where the majority of wolves are, landowners can only kill wolves
if they can demonstrate an immediate threat to pets or livestock. In the rest of the state, where
there is more agriculture and more people, the rules are more lenient. On their own property,
landowners can kill any wolf they feel is a danger, without having to prove anything to the state.


The Sierra Club is opposed to taking the wolf off the Endangered Species list, largely because
of Minnesota’s management plan. Ginny Yinling is the chair of the Wolf Task Force of the Sierra
Club in Minnesota.


“They’ve pretty much given carte blanche to landowners, or their agents, to kill wolves
pretty much at any time in the southern and western two thirds of the state; they don’t even
have to have an excuse, if a wolf’s on their property they can kill it. Instead of this being
what should have been a victory in terms of wolf recovery and the success of the Endangered
Species Act, instead we’re afraid it’s going to turn into something of a disaster.”


Yinling is also concerned with the protection of wolf habitat, such as den sites, rendezvous
sites, and migration corridors.


“The current management plan protects none of those areas; it leaves it entirely up to the
discretion of the land managers.”


But wildlife managers say these are not critical for a large wolf population
like Minnesota’s. Mike DonCarlos is the wildlife program manager for the Minnesota
Department of Natural Resources.


“As you look at the range of species that are threatened by habitat change, ironically the wolf
in Minnesota is not one of them. As long as there’s a prey base that continues, wolves should
do just fine. The key is mortality rates and availability of food.”


In Wisconsin and Michigan, where there are fewer wolves, state laws will continue to protect
wolf habitat. Peggy Callahan says she has faith that the wolves will be fine, even if the
Minnesota state plan is not perfect. But at the Sierra Club, Ginny Yinling says they have
plans to challenge wolf delisting in court.

Eagle Soaring Off Endangered Species List

The American Bald Eagle is expected to come off the endangered species list soon.

The American Bald Eagle is expected to come off the endangered species
list soon. Once a victim of hunting and pollution, the eagles are
rebounding, but scientists say monitoring must continue, for the sake
of the eagles and the sake of the environment. The Great Lakes Radio
Consortium’s Bob Kelleher reports:


If you’re looking at all, it’s hard to miss the bald eagles here. The
majestic birds glide overhead, or silently perch on a waterfront tree.
Their nests – made of branches – fill the treetops – sometimes ten feet
across, close to the lakes of Northern Minnesota’s Voyageurs National
Park.


Twenty years ago you might have been hard pressed to spot America’s
national symbol. Park Biologist Lee Grim says, it was obvious that
eagles were struggling.


“We saw how some of these birds were ill, and sick, and they had avian
pox and things. Something was keeping them from being healthy.”


An eagle found here in 1989 had the highest blood concentration ever
found of contaminants like the chemical PCB.


“So, we wanted to know why is that up here in Northern Minnesota, in
the middle of a beautiful, you know, almost wilderness area.”


It’s still a mystery how industrial chemicals like PCB’s get here, but
we do know what’s hurt the bald eagles in the past. The insecticide
DDT made bird eggs fragile – more likely to break under an eagles
weight than hatch. And Grim says DDT was all over the place. It was
sprayed on the region’s forests to kill insects like the spruce
budworm.


“DDT is pretty much everywhere, it has been, you know. And it’s a
pretty long lived chemical.”


At the top of the food chain, chemicals like DDT accumulate in the
eagle’s bodies. Sick eagles can indicate a poisoned environment. To
test the environment, you test the eagles.


(snd of climbing)


A naturalist is scaling 90-feet up one of the park’s White Pine trees
to the huge nest at the top. The parent eagles circle overhead –
noisily upset. There’s a pair of hatchlings – fuzzy, beaky, and
surprisingly big 8-week old bald eagles. They have bright yellow feet,
with shiny black, and what will become very dangerous talons. Soon,
one’s squirming in an orange bag, and lowered into the hands of
graduate students Faith Wiley and Katie Parmentier.


(snd of students talking about baby eagle)


In minutes, the young female is back up; short a few feathers for
mercury testing; and a little blood for other chemical tests. There’s
a pair of metal bands riveted around her ankles.


Bill Bowerman is an environmental toxicologist from Clemson University.
His testing proves that chemicals like DDT and PCB’s are slowly going
away, but chemicals were only part of the problems for bald eagles.
Man was another problem. It took decades to get people to stop
shooting eagles; or to catch them accidentally in beaver traps, but
it’s better now.


“It’s evident, when I go out to landowners that have eagle nests on
their property, that they know how to manage their eagles; how to keep
people away; and how to protect that eagle during that critical nesting
period.”


It’s believed there were once half a million bald eagles in North
America. As people spread, by the 1950’s, bald eagles nearly vanished.
In the lower 48 states, the last few hung on in places like the Great
Lakes.


In Voyageurs Park, bald eagle numbers have jumped from seven nesting
pairs in 1973, to 28 pairs today. There are more than 7-thousand
breeding pairs nation wide, but there are always new threats. One of
the nation’s first victim’s to West Nile disease was the bald eagle in
New York area zoos. Bowerman says several pair are missing now in
Michigan, and there are always new chemicals. Traces of poly
brominated flame retardants are doubling in the Great Lakes basin every
3 to 5 years. Bowerman says the chemical industry needs strict
monitoring.


“As long as we maintain our vigilance about the environmental toxicants
that are being created each year, we should be having the eagles
protected.”


Bowerman supports de-listing, but doesn’t want the birds in the
predicament they were twenty years ago. An official announcement of
the bald eagle’s de-listing is expected later this year.

Biologist Fosters Bald Eagle’s Return

In the 1960’s, the bald eagle was in trouble. There were only about 4
hundred birds living in the U-S And in some states, pollution had wiped
them out altogether. But the bald eagle has made an impressive comeback.
The U-S Fish and Wildlife Service recently announced plans to remove it from
the endangered species list. As the Great Lakes Radio Consortium’s Karen
Kelly reports, it’s good news for the scientists who fought to save this
bird:

Bald Eagle Birth for All to See

Most people surf the web for things like stock prices, chat rooms and
pornography. But a bird enthusiast in upstate New York is hoping to
catch their attention another way. He’s using a website to share the
birth of baby eagles with the rest of the world. The Great Lakes Radio
Consortium’s Karen Kelly reports.

Bald Eagle Reproduction

Bald eagles living near Lake Superior aren’t reproducing as frequentlyas those who nest on inland lakes. A new study blames the lack of foodrather than contaminated fish…and one of the study’s authors says policymakers should take note. The Great Lakes Radio Consortium’s ChuckQuirmbach has more:
