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 Great Blue Heron

Transcript

Some people say robins are the first sign of spring. But there’s another bird that makes a dramatic entry in northern states. The Great Blue Heron soars in to make a nest… and guard it:

On an island in the Upper Mississippi River, a stand of cottonwood trees is silhouetted against a gray sky. The bare branches are festooned with big nests, made of twigs and branches. Next to the nests, like sentinels at the castle gate, stand Great Blue Herons. These birds are four feet tall. More than a hundred of them are claiming their domain in these trees, just upriver from downtown Minneapolis. When one takes off and glides away, its six-foot wing span dwarfs the ducks and songbirds sharing the island.

It’s hard to tell the males from the females because they’re the same blue and gray. Birder Sharon Stiteler is leading me on a tour of this rookery.

“The males arrive first, and they work out who’s going to take which nest. Where you see one bird standing up, that is most likely a male. He’s hanging out there because the other males who are still waiting to attract a female could come by and steal sticks out of his nest to make his nest look better.”

On some nests, you can see females already sitting on pale blue eggs the size of small mangoes. But Stiteler says herons are not always good parents.

“If the chick falls out of the nest and lands on the ground, that chick is toast: the parents will not continue feeding it. And oftentimes you’ll see turkey vultures hanging out at rookeries, and they’re waiting for the young to fall and starve, and then they’ll have a whole bunch of food.”

But at least on this island, there won’t be many predators like coyotes or foxes.

These birds were once threatened by humans. Their cousins the egrets were hunted for their beautiful white feathers, and both suffered disastrous population loss until the pesticide DDT was banned.

Now you can see them in streams and lakes all over. They breed in Canada and the upper midwest. They spend their winters wherever they can find food. Herons literally stalk their prey.

“They have a lot of patience, and they just stare at one spot for long time, and then they jab down and grab the fish. Their beak is shaped like a pair of super-sharp chopsticks. Sometimes they catch a huge fish and they have to juggle it around, especially if they have it perpendicular with their beak, they have to jostle it around, and the fish is wiggling, and eventually they get it just right so it’s straight in line with the bill, and you can watch this huge thing slide down that long slender neck.”

Sharon Stiteler is a part-time naturalist with the National Park Service, and she writes a blog called bird-chick-dot-com.

Today the herons are pretty quiet. But Stiteler has a Blackberry loaded with their sounds, including the prehistoric squawk they make when they’re startled.

And Stiteler says it can sound really strange when the young are clattering for food.

After the young are raised — at least the ones that survive — the herons will stay here on the river, until it freezes over and they can’t fish anymore. Stiteler says the birds decamp all at once.

“One day we have Great Blue Herons, and the next day they’re gone, and they migrate at night.”

They tuck back their long necks when they fly, forming an S-shape and hiding their true length.

Stiteler says the recovery of Great Blue Herons, along with pelicans, eagles, and other birds near the top of the food chain is a sign of a healthier ecosystem.

Mapping Underground Rivers

  • DNR hydrologist Jeff Green consults a high-resolution topographic map to figure out which sinkhole is ahead of him. The trees and grass that grow up around the sinkhole form a buffer, allowing water to soak into the soil and filtering any pollutants before it reaches the aquifer.(Photo courtesy of Stephanie Hemphill)

Spring in the north is a time of melting snow and running water. It’s the best time of year for people who study underground water flows. Those underground rivers are important, especially where surface water easily drains into bedrock. It can quickly carry pollution long distances. Hydrologists try to map these underground rivers to help protect fragile ecosystems. As Stephanie Hemphill reports, the first step in making these maps is a process called dye tracing.

Spring in the north is a time of melting snow and running water. It’s the best time of year for people who study underground water flows. Those underground rivers are important, especially where surface water easily drains into bedrock. It can quickly carry pollution long distances. Hydrologists try to map these underground rivers to help protect fragile ecosystems. As Stephanie Hemphill reports, the first step in making these maps is a process called dye tracing.

When the snow is melting in the woods and fields, Jeff Green wants to know where it’s going.

“We’re going to hike back to two springs.”

Green is a hydrologist with the Minnesota Department of Natural Resources, and an expert in the limestone geology of Southeast Minnesota.

Green climbs a fence and splashes through a stream that’s flooding a pasture. The stream is bordered by a natural wall of limestone.

Melting snow seeps into the limestone. It runs down vertical cracks to bigger horizontal openings that look like miniature caves. Jeff Green calls these “conduits,” and some are three inches wide.

“You can imagine a pipe that big — water would move very fast, like we’re seeing. So these conduits are what we’re dye tracing.”

Green has traipsed out to this pasture to put what he calls a “bug” in a spring. The ‘bug’ is a small mesh bag about the size of a cellphone, packed with charcoal. The charcoal will capture a dye that he’ll pour into melting snow in a sinkhole a few miles away. He’ll do this in several different spots.

By tracing the paths of different colors of dye, he’ll learn the sources of the water that feeds each spring. That will help him make what he calls a springshed map.

We slog across a corn field that’s dotted with small groves of trees. They’re growing around miniature canyons, about 20 feet deep. Here, you can see how this honeycombed water highway works, and this is where Jeff Green will pour the first dye.

“This is a place where there was a conduit, an opening in the limestone.”

Green climbs down carefully into the crevasse.

“Listen! … All right!”

He’s found some running water.

“Water’s running right here. I don’t know where it’s going but it’s going someplace. So I’m going to try pouring dye here.”

He pours a cup or so of a bright red fluorescent dye into the snow.

Green marks the spot with a GPS unit. This is a place where surface water and groundwater meet.

“That snow-melt is surface water, it’s going into this sinkhole and it’s becoming groundwater as you’re listening to it.”

That means what happens here on the land directly affects the quality of the groundwater.

“In this case, it’s pretty good, you’ve got conservation tillage, lots of corn stalks left to keep the soil from eroding, and then you’ve got grass, permanent cover, around the sinkholes. So this is actually really good.”

There are wonderful trout streams around here. The map Green is making will help protect those streams by pinpointing the source of the water that feeds them.

In a day or two, Green will check the “bugs” he put in the springs, and find out exactly where the dye from this sinkhole went.

He usually finds water traveling one-to-three miles underground before it surfaces.

When the springshed map is finished, he’ll share it with local governments, farmers, and people who want to protect the water in this landscape.

Keeping It Close to Home

People concerned about energy are
getting more and more interested
in producing their own. Stephanie
Hemphill reports on an effort to
harvest the wind, and other natural
resources, to power a community:

(sound of climbing)

Three students are getting ready to climb a TV tower on Moose
Mountain on the north shore of Lake Superior. They’ll put up three
anemometers – little cups that spin in the wind and measure how fast
it’s blowing.

As they deploy their climbing equipment, their professor, Mike
Mageau, keeps asking if they have enough safety gear. He seems a
little anxious.

“Two of them are mountain climbers. So they seem to think this will
be no big deal.” (laughs)

Mageau teaches at the University of Minnesota Duluth. He’s been
measuring the wind on the high ridge that runs along the Lake
Superior shoreline.

“If you look at the statewide wind maps, they don’t give us credit for
having any wind along the North Shore of Lake Superior. But Grand
Portage was interested in wind, and they did some monitoring and we
helped them. This was years ago.”

That’s the Grand Portage Band of Ojibway Indians. Mageau got a
grant to install monitoring equipment up and down Lake Superior
shoreline.

“And we found 15 to 20 mile-an-hour average wind speeds at the
sites.”

That’s about the same as the best wind sites in Iowa, where huge
wind farms spread across the landscape.

Mageau doesn’t advocate a big wind farm here. Instead, the idea is
to put up one windmill for each community along the shore. One big
turbine could supply roughly half the electricity each town uses.

He knows some people are nervous about this. The North Shore of
Lake Superior is beautiful, and no one wants to ruin the scenery. It’s
also an important route for migrating birds. There’s concern that
birds could fly into the spinning blades. A separate group of
researchers is studying the migration routes.

“Are they flying close to the lake, along the peaks, just inland or
lakeside of the peak, where are they flying? So hopefully when we
pick a wind site we’ll stay away from the birds.”

If a wind tower is ever built here, the power would go to the town of
Grand Marais Minnesota, 20 miles north. And it would fit in with other
projects local folks are working on, to become more energy self-
sufficient.

Buck Benson owns the local hardware store. He says he and his
friends, George and Lonnie, hatched the idea while they were fishing.

“We were grumbling about all this stuff, ‘what can we really do.’ And,
when we came back home, George kept prodding us, ‘you know what
we talked about,’ so we formed a little group. And I think we’ve done
good work since we started this organization.”

The group has been researching various ideas about how to produce
energy locally. One team is pursuing that windmill idea we heard
about. Another project is a little closer to being built: they want to
burn the wood chips from a local sawmill in a central heating system
for the town.

(sound of buzzing)

The chips would come from Hedstrom Lumber mill. Howard
Hedstrom says the mill sells bark chipped off the trees. But he has to
haul it miles away to sell it.

“By the time you pay the freight, there’s not much left. And if it could
be used locally, why not use it locally and save all that transportation
cost.”

The city of Grand Marais has applied for a federal grant to pay for half
the cost of the boiler.

Communities across the country are looking to use what they’ve got
around them, instead of importing energy from a big coal or nuclear
plant miles away.

It helps keep money close to home, and it could be better for the
earth.

Cleaning Up the Car Wash

Transcript

Many business leaders are taking a serious look at their environmental impact. Companies from Ikea to Home Depot are following a science-based approach to sustainability called the Natural Step. Stephanie Hemphill visited one small business that’s rethinking its operations:

You probably wouldn’t think a car wash would be the kind of place that pays attention to the environment. But this one is.

It’s trying to become more sustainable — putting back what it takes away.

“What we’d like to do is, we’d like to be a closed system, a closed loop.”

Frank Nicoletti is the manager of this car wash in Duluth Minnesota.

“That’s the goal of the whole Natural Step is to be closed loop, meaning nothing goes in or out, and you just recycle the whole time. Of course, how feasible it is we don’t know. ”

Nicoletti is trained as a biologist. He’s the kind of guy who spends a lot of time watching the hawks as they migrate across the western tip of Lake Superior. It’s right across the street from the car wash.

His concern about nature is bubbling over into his business.

When a local non-profit group brought in Natural Step experts, Nicoletti and a dozen other business people signed up to learn how ecosystems work, and how they could operate their businesses more sustainably. They started looking over their operations from top to bottom to see how they could make them more earth-friendly.

One big change they’ve made at the car wash is switching to a biodegradable detergent. That’s not required by law, but it’s one of the principles of the Natural Step program — to reduce the use of man-made toxic substances.

“Everything that’s on line here is non-persistent so it breaks down in the environment.”

As cars move through the wash, the first flush of soapy water is captured in a pit the below the floor, and re-used.

The rest of the waste water is treated at the local sewage treatment plant, so grease and oil and other pollutants aren’t going into Lake Superior. Around the country, most car washes send their waste water to treatment plants, and Frank Nicoletti says it’s better for lakes and streams when people use a car wash instead of doing it on the driveway at home.

Here, the used oil from the lube operation is another part of that closed loop.

“We have two special boilers in our basement that actually recycles the oil and heats part of the building as well as heating all of the hot water.”

And the company recycles the cans and bottles they haul out of the cars they wash. They use the money from the recycled trash to give the people who work here a free lunch once a month.

“The amount of trash that comes out of these vehicles is unbelievable. We’re actually putting less trash in the garbage can now that we’re recycling, which is a great thing, and we’re also helping our guys out by giving them lunch once a month on these recycled cans.”

That’s another part of the Natural Step. It says a sustainable business will make sure its employees can meet their needs. And since they started recycling the trash from the cars, a lot of the workers are recycling at home now too.

Frank Nicoletti says he’d like to make the business fit in with nature even more — by rebuilding the roof.

“I’d love to make butterfly garden up there, and that will actually clean the air. Because the butterfly migration and the dragonfly migration through the lakeshore here is just huge. I mean, there are days when the dragonflies are going by, you can see a million — of different species.”

When they’ve finished a year’s worth of training and work, the car wash and the other businesses trying out the Natural Step approach will share their experiences with others in the community.

Frank Nicoletti says it’ll be like a pebble dropped in a pond. There’s no telling how far the ripples will go.

some non-profits are getting involved.

She recently visited a church that’s

thinking more about its impact on the

environment:

The folks at Gloria Dei Lutheran Church in Duluth Minnesota are studying
more than their Bible these days. They’ve been learning about how the
ideas in the Natural Step can make their church operate more sustainably.

One Saturday in the church basement, about a dozen people from churches
around the region are talking about what sustainability means.

Judy
Isaacson is from a small church in the country.

“It’s a growing understanding that we as individuals have to be responsible
for what we do, and then I think a big part is helping people understand
it’s not that difficult to live up to what our values are and what we see
happening.”

Isaacson says it’s easier to talk about the practical ways to be
sustainable than to expound on the theory. She’s been learning how to
encourage everyone in her church to get involved in making small changes.
Like using less electricity.

“We’re the newbies at our church; we’ve only been in the church six years.
And by having someone who’s been there forever change the light bulbs, it
was very easy because she had credibility within the congregation.”

For many Christians, the Natural Step fits right in with what they call
“creation care.” For them it means taking care of what God created.

The Natural Step publishes its principles on the internet, along with
inspiring examples of how it’s working in various places around the world.

In Duluth, a non-profit group brought the Natural Step to town. Experts
from Canada gave several day-long training sessions to about a dozen
businesses and organizations that committed to a year-long effort to put
the ideas to work.

Sue Anderson took part in the training. At the Saturday workshop in the
church basement, she mentions some of the things the church has done.

“The use of glasses and cups, reuseable items. We kind of got that going
through a lot of different committees, you know our neighborhood breakfast
and things like that.”

No more throw-away styrofoam cups. That fits in with one of the principles
of the Natural Step: don’t wreck the earth by building more landfills than
you absolutely have to.

Another principle is: use less fossil fuel, and other resources that have
to be mined from the earth.

When they replaced the roof at Gloria Dei, they added a lot of insulation.

David Carlson is pastor of Gloria Dei. This year he used Lent as a chance
to educate the congregation. He asked people to go on a “carbon diet” for
Lent.

“There’s usually a confession and forgiveness of not only the brokenness
that we have with God and between us and other people, but also the
separation that we have with creation. And this is one way that we can
participate in the healing of God’s creation.”

Carlson says a lot of church members are taking on projects. One man is
promoting the idea of ride-sharing to church.

“He is offering a free pillow-pack of fair trade coffee to anyone who comes
to him during coffee hour and says that they car-pooled that day. It’s
trying to remove barriers for people that may be in the way of taking
further steps. And they may be small. But they may make a difference.”

The biggest difference this group might make is offering their experience
to others. The non-profit group behind the Natural Step in Duluth is
documenting their progress and hoping others will join in.

Serving It Up Green

Some big corporations and some small businesses are taking a serious look at their impact on the environment. Some are using a science-based framework called the Natural Step to try to operate more sustainably. Stephanie Hemphill visited one, and has this report:

The Duluth Grill is a family restaurant. Tom Hanson is the owner here. He says things started changing for the restaurant when he decided he should be offering healthier foods. He says too many of us are gaining too much weight. So he changed the menu, and now he says people can still go out and have a good time without it all going to their waist.

“Whether it’s French fries or fruit or healthy home-made soups, people can be socially engaged eating out but you’re not necessarily sacrificing your eating habits or eating styles.”

His menu offers healthy ethnic meals, gluten-free foods, and teas that claim health benefits.

Once Hanson started thinking about the health and well-being of his customers, he started thinking about the other impacts of his business. He joined a group of about a dozen businesses recruited by a local non-profit to try out the Natural Step approach to sustainability. The Natural Step was developed in Sweden, but it’s being used all over the world.

Restaurant staffers attended training sessions on how ecosystems work, and on what it means to be sustainable.

Manager Jeff Petcoff shows off the new LED lights in the restaurant.


“They produce 12 watts of energy versus 320 watts from the regular light bulbs that we were using prior to this. It’s a little more intimate with dining at night, but we’ve had a positive reaction to that as well.”

The Natural Step program encourages reducing the use of fossil fuels and other resources that have to be mined from the earth. And it calls for not throwing as much garbage into the earth.


In the kitchen, workers separate the trash. There’s a bin for recyclables, one for trash, and one for food scraps. Petcoff says the food waste goes for compost.

“We’ve just made it very easy for our staff to be able to compost and recycle with the bins all over the restaurant.”

The Duluth Grill has reduced its weekly trash pickup, and saved a bunch of money in the process. Owner Tom Hanson says saving money is nice, but part of the Natural Step program calls for not degrading the earth, like by building landfills.

“We don’t live next door to landfill but somebody does, and once you become aware of it, I think, it becomes more compelling to do it.”

And the restaurant encourages its customers to get involved in helping each other. Next to the front door there’s a bin where people can dump their old magazines. A local youth center is recycling them to raise money.

And there’s a bookshelf where people can leave children’s books; it’s part of a community-wide literacy campaign.

One Natural Step principle is about people: a sustainable business operator makes sure the people who work there, and even the suppliers and customers, anyone who has contact with the business, can meet their needs without a big struggle.

Tom Hanson dreams of offering health coverage to all his staff — and maybe someday even child care.

“You could easily consider day care for your staff as being an expense that no small operator could afford. But when you make change little by little, that step could very well enter into our values, and once it becomes one of our values it becomes affordable.”

Many businesses are making these kinds of changes and you might not even be aware of it. But Tom Hanson would say if you’re not sure, ask. You might prompt someone else to do better.

Trout Used as the ‘Canary’ in a Stream

Suburban growth typically degrades
the quality of rivers and lakes. But
developers are finding ways to protect
water quality even as they build housing
developments and malls. Stephanie Hemphill
reports on a stream in a major metropolitan
area that still has trophy-sized native
trout in it – and how people are working
together to protect the trout:

A half dozen people in waders stand nearly waist-deep in a bend of
the Vermillion River. They’re getting ready to send electric shocks
through the water.

(sound of gas motor starting)

They’re looking for trout.

They’re stunning the fish so they can catch them in nets. When they
have about ten fish of all sizes in their bucket, they pull their boat to
the side to count and measure them.

“You can see on the one he’s pulling out right now, it’s a male, it’s got
that big hook jaw on the front. 532. These are millimeters; that’s
about 21 inches. ”

Brian Nerbonne is a trout habitat specialist with the Minnesota
Department of Natural Resources, and today he’s a happy man. He’s
collecting a healthy batch of trout on this river just thirty minutes from
downtown Minneapolis. He figures the big ones they’re finding are
about six years old.

“Fish grow really fast in the Vermillion: you saw when we were
shocking there’s a lot of a other fish, suckers, creek chubs, and things
like that they can eat, they grow a lot faster eating those other fish
than if they were just eating bugs.”

Biologists regard trout as a kind of canary in the coal mine. These
trout are healthy, and that’s a sign that this river is healthy for all
kinds of animals, including people.

As you walk along the stream, you can see schools and houses and
roads literally a stone’s throw from the river. Typically, development
like this threatens the trout, because it produces warm, dirty storm
water runoff.

Twenty years ago, a local sportsmen’s group asked the state to
designate parts of the Vermillion River as a trout stream. That would
mean local governments would have to do more to protect the water
quality, and not all of them were happy with the idea.

State planner Michele Hanson had the task of coaxing local officials
to get on board.

She did that by doing what the DNR is doing today – shocking the
river to show local officials there was something there worth
protecting.

“Once everyone believed us that it’s trout stream, then we went out
and met with every community along the river, of the section that we
were going to designate as trout stream, to tell them what it would
mean to them, what changes might happen.”

It would mean every town, every township and county that the river
flowed through would have to make some changes in the way they
developed.

Now, in some sections of the river, builders must leave a buffer to
protect the stream, as much as 150-feet wide.

Also, they need to avoid increasing the amount of runoff. Rainwater
that sheets off roads and driveways and rushes directly into the river
is too warm for the trout.

Builders are learning how to get the water to soak into the ground
instead. They can build narrower streets and shorter driveways.
They can build rain gardens and other landscaping that holds the
runoff long enough that it can soak in.

The state is also building structures in the river to provide better
hiding places and spawning grounds for the trout.

(sound of counting fish)

It’s all aimed at holding onto a rare treasure – a healthy trout stream in
a major metropolitan area.

At the Mississippi Market food co-op in St. Paul, there’s a brand-new
solar collector on the roof.

The electricity goes to a box attached to a lamppost in the parking lot.
A cord comes out of the box; at the other end of the cord is a normal
three-prong plug, and it’s plugged into the back end of a Prius.

“The battery is installed in the spare tire wheel hub.”

Chris Duffrin is taking me for a spin in the Prius.

“You just unplug the plug back here, and you enter the car just like
the rest of our cars — you use your key fob to scan in. That pops the
locks open.”

The key fob is programmed with your account information. It gets
you in the car, and tells the computer when you’re using the car and
when you bring it back. The key to the Prius is in the car.

“power up…”

The computer screen on the dashboard displays all kinds of
information, including data on the most recent trip.

“There’s the trip I just took to South Minneapolis for a meeting; we
went 18 miles round-trip; we got 94.8 miles per gallon. With our plug-
in we often get in the 90s, and at times we’re running over a hundred
miles per gallon.”

There’s still an engine in the front, and it kicks in when you accelerate
quickly. But the primary power is delivered by the battery. These
vehicles get about twice the mileage of a standard Prius.

Chris Duffrin is Executive Director of the nonprofit Neighborhood
Energy Connection. One of its projects is HourCar, a three-year-old
car sharing program.

“You can get some trips in this car where you are literally emitting no
carbon.”

It costs about $10,000 to add the battery, and the solar collectors cost
about $18,000.

“What we’re trying to do is demonstrate that, when those prices start
coming down, this is something people can do. And not just for
themselves, but if they share a car and share those costs, then this
can become a really efficient, clean way of traveling.”

Duffrin says at first, the people who joined HourCar were mostly
motivated by concerns about the environment. But now people want
to save money on gas. He says membership grew by 70% in the last
year. Still, it’s a tiny number: there are 650 members. They share 16
cars, parked at about a dozen locations around St. Paul and
Minneapolis.

The payment plans include a monthly fee and a charge per hour and
per mile.

HourCar is helping just a tiny handful of people reduce their carbon
footprint. But their individual choices are moving the whole society
toward better answers, according to J. Drake Hamilton. She’s a
climate change expert at Fresh Energy.

“When companies and policy makers see that people really want
better options out there — they want smarter ways to get to work, and
they want cleaner cars — that’s a time to step in and say, ‘Okay we’re
raising the bar, we’re keeping climate and people’s pocketbooks in
mind, and we’re making better choices available everywhere.'”

HourCar is installing another solar battery-charger at a light rail
station. Members say as mass transit options improve, more people
will be able to get along without their own car.

Red-headed woodpeckers used to
be just about everywhere east of the Rocky
Mountains. But these days the number of
red-headed woodpeckers is about half of
what it was fifty years ago. Stephanie
Hemphill reports volunteers
are working on a new project to get people
to help red-headed woodpeckers. They’re
encouraging landowners to let dead or dying
trees stand rather than cut them down:

You can’t miss Red-headed Woodpeckers. They have long beaks,
bright red heads and snowy white breasts. And if you go to the right
place, you can find a lot of them.

“Somebody told me that there was Red-headed Woodpeckers up
here, so I walked five minutes, and there was a Red-headed
Woodpecker, and it flew into a hole in a tree, and I says, ‘wow, this is
easy.’”

Lance Nelson first visited the Cedar Creek Ecosystem Science
Reserve about a year ago.

“And then I came up this year and found 8 nests. But the young
make a lot of chattering, so you can usually tell where the nest is.”

Today they’re not hammering on trees – the sound most of us
associate with woodpeckers – but they’re doing plenty of chattering.

This reserve in southern Minnesota looks a lot like how much of the
Midwest used to look.

There are clumps of big oak trees here, separated by open areas of
native grasses, shrubs and wildflowers. The biologists call it an oak
savannah.

And there are Red-headed Woodpeckers everywhere – about fifty of
them on this 500-acre patch of ground.

“There’s a red-headed, and he’s got a baby with him. God, they’re
beautiful. They are so beautiful.”

That’s Chet Meyers. After a career as a college professor, he’s now
in charge of an effort to make more places where Red-headed
Woodpeckers can build their nests and raise their young.

If they can figure out exactly what the woodpeckers like so much
about this place, maybe they can come close to reproducing the
same conditions other places.

Chet Meyers is marking every tree where the woodpeckers have
nested.

“See these two trees to the left, go to the right-most one, it forks, and
there’s a broken-off snag up there, looks like a ‘Y’. That’s where the
babies were sticking their head out a couple weeks ago. It was really
cute.”

Once the trees are marked, the group will catalog exact descriptions
of each tree. They’re hoping to come up with a profile of the perfect
home for Red-headed Woodpeckers.

“And we’re going to measure the diameter of the tree, how high the
nest cavity is, the species of the tree, is it alive or is it dead, so we
can get some data on what seems to be the preferred habitat.”

Once they’re pretty sure they know what the woodpeckers like, they’ll
reach out to land owners. They’ll to try to get them to leave dead and
dying trees standing.

That could work on old abandoned farms, where there are trees and
open spaces. Or in cemeteries. Or around golf courses.

“If our theory – see, this is all theory – if our theory is correct, the golf
course replicates an oak savannah and there should be birds there.
So, that’s what we’re hoping.”

And Meyers says helping woodpeckers means helping other wildlife
too.

“The woodpecker is called a primary nester, it digs the cavity. But
flying squirrels, mice, snakes, bluebirds, tree swallows – there are lots
of other animals that are secondary nesters. They can’t drill the hole.
But they live there. So what we’re trying to do is preserve the habitat
so the woodpeckers drill the hole and when they leave, something
else will come in and live in it.”

The researchers think if you have dead or dying tree, that could be a
home for a Red-headed Woodpecker. But usually homeowners are
worried the tree could fall and damage something, Meyers says you
can cut off the top and some of the bigger branches and leave the
rest of the tree standing. They think the red-headed woodpecker will
be just as happy.
