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.”

Lessons From a Skyscraper

America’s tallest skyscraper. Soon,
the Willis Tower will start an environmental

You might have heard the Sears Tower
in Chicago is now called the Willis
Tower. But there’s more changing for
America’s tallest skyscraper. Soon,
the Willis Tower will start an environmental
facelift that could cut eighty-percent
of its energy use. You might wonder:
what could a homeowner learn from what
the Willis Tower is doing? Shawn Allee thought it wouldn’t hurt to ask,
and went on a tour for the answer:

One of the co-owners of the Willis Tower is John Huston. He says there’s plenty for
people to learn from the tower’s green rehab plans. To start – we’re at the base of the
tower, and we’re craning our necks up.

“We’re facing north. We’re looking at a hundred and ten floors, so that’s 16
thousand windows in total.”

Huston says those windows are the old single-paned kind common in 1974 – back
when the Willis Tower was finished. In the summer, the windows let heat in, and
during the winter, they let heat escape. And that black metal you see in photos? It
does the same thing.

Huston: “The building is clad in aluminum if you went outside in the winter, you
certainly wouldn’t want to wear an aluminum ski jacket.”

Allee: “You’d freeze.”

Huston: “Exactly.”

So, Huston says the first thing they’re gonna do at the Willis Tower is what he calls
“tighten the building’s envelope.” It means insulating the building from the outer
walls and replacing the windows – all sixteen thousand of ’em.

“It’s an incredible job. That’s what we have to change in order to conserve the 80%
of energy that we anticipate doing.”

Huston says energy consultants pretty much give homeowners the same energy
advice. He says, the nice thing is, once you do that it’s easier to figure out what’s
next.

“Watch your step.”

Huston takes me into the guts of the Willis Tower. This is where it’s heated and
cooled. He says since the building’s gonna waste less energy, he won’t need such
powerful equipment.

Huston: “A lot of what’s in here will disappear or shrink.”

Allee: “So what is this?”

Huston: “This is an electric boiler. It provides hot water to heat the building. Each
one of these consumes enough electricity to heat and light a town of 6,000 people.
We have eight of these throughout the building. It’s not just the boilers. in this
section behind us, you have all the pumps that move hot water throughout the
building. Each one of those pumps is hooked to an electric motor, and 50% of them
can be eliminated.”

Huston says the take-away here is that once a building requires less energy to heat
and cool it, the other savings can kind of cascade from that.

But there’s another lesson homeowners can learn from the Willis Tower’s green
rehab.

The architecture firm that planned this project is called Smith and Gill. Gordan
Gill tells me, their work was made easier by the fact the Willis Tower owners keep
records of their power use.

“When you’re designing something new, you’re predicting the performance of
something. Here, you can actually test it, since you have records of how much
energy was spent, how much energy was used – you know where you stand, exactly.
And so now, you can do mock-ups and tests and things like that.”

Gill says that’s a good reason for homeowners to hold onto their power and heating
bills, too. He says if you’re confident in your actual costs and likely savings, you’re
more likely to follow through with your rehab project.

“And that’s important because you’re avoiding the obsolescence of these buildings,
and I think that’s true from everything like Willis to people’s houses.”

Fcc to Reduce Bird Kills?

Scientists have found that millions of birds are killed each year when they crash into communication towers. Now officials at the Federal Communications Commission are thinking about making companies change the way they build the towers. Mark Brush has more:


The explosion of cell phones has meant an explosion of new communication towers, but when these towers are built using guy wires, and use traditional lighting systems, they can end up really hurting bird populations.


Steve Holmer is with the American Bird Conservancy. He says the steady red lights on these towers can confuse birds that use stars to migrate at night.


“The birds are actually attracted to these towers, kind of like a moth to the flame, and will actually circle around them and strike the towers, or strike the guide wires, or actually just keep circling until they exhaust themselves.”


Holmer says that simply replacing these lights with white strobe lights would help a lot.


The FCC will be seeking public comments on whether or not they should require that new communication towers be bird friendly.

Conservation groups want the FCC to be more careful about allowing the
building of communications towers. The groups say the fate of millions
of migratory birds may be at stake. The Great Lakes Radio Consortium’s
Chuck Quirmbach reports:


A lawsuit recently re-filed in federal court charges the Federal
Communications Commission with failing to comply with several
environmental laws in its licensing of communications towers.


David Fischer of the American Bird Conservancy says the FCC rarely
considers the potential effect of towers on birds.


“On birds that have been known for many years now to fly in or around
or otherwise impact towers and either injure themselves or die.”


The lawsuit specifically involves towers along the Gulf Coast… which
is on the migration route of many birds that spend summers in the
Midwest. But the Bird Conservancy says the case may set an example for
tower projects all over the U.S.


The FCC says it doesn’t comment on pending litigation. The
conservation groups first brought their case three years ago.

Wind Turbines Stir Up Neighbors (Part 2)

Most people think renewable energy is a good idea. It’s better
than burning fossil fuel to create electricity. But “green energy”
alternatives
can be controversial. Windmill farms are springing up all across the
nation.
Some people think the windmills are eyesores. But others say windmill farms

Most people think renewable energy is a good idea. It’s better than burning fossil
fuel to create
electricity. But “green energy” alternatives can be controversial. Windmill farms
are springing
up all across the nation. Some people think the windmills are eyesores. But others
say windmill
farms can help preserve the agricultural landscape by supplementing the income of
farmers.
The Great Lakes Radio Consortium’s Linda Stephan reports:


For 30 years, Matt Mauer raised crops and livestock on his farm about 10 miles from
the Lake
Michigan shoreline. Today, he’s in his backyard looking at the land now farmed by
his daughter
and son-in-law. Standing there, he feels a crop they’re not harvesting.


“The good Lord makes it windy all the time for us, so let’s use it, you know.
Because I’m like
everybody else. When I get up in the morning, I want lights.”


Mauer’s hoping to put four wind turbines on his family’s farm near Ludington,
Michigan. That
would power about 24-hundred homes. Nearby, a renewable energy company’s working with
other farmers to build a hundred turbines in the area. Mauer says many of his
neighbors want in
on the deal because they think wind energy could help save their farms.


“It’s hard to make a living just farming right now. And I consider the wind one of
the crops that
we could harvest. It will help keep farmers on the land. Like if, in this place, if
we could get
seven–thousand dollars a year, six-thousand dollars a year for four of them, that’d
make it a hell
of a lot easier to keep the people here and farm.”


The state government’s backing similar projects. It’s training financial advisors
to show farmers
how they can turn a profit with windmills.


But not everyone likes the idea. Some people who live in the area around the
planned windmills
say they’re worried the towers would destroy the region’s charm. That’s linked to
property values
and to tourism. And they don’t like the size of the proposed windmills. Each one
would be four-
hundred feet tall. The blades would have a diameter nearly as long as a football
field.


It’s a story that’s heard in many places. Cape Cod, Massachusetts, the prairies of
Illinois, and
around the Great Lakes. For example, a Michigan couple who wanted large-scale
turbines on
their property ended up losing a court-battle against local government that opposed
the plan. And
two turbines already in place in Mackinaw City – between Lake Michigan and Lake
Huron –
have some unhappy neighbors as well.


Thomas and Virginia Alexander’s home is about 15-hundred feet away from the windmills.
They’re in their eighties and they both wear hearing aids… but even without them,
they say the
windmills are loud…


Tom Alexander: “There’s things about it we don’t appreciate, at times the noise –
not always –
depending upon the wind and the direction.
Virginia Alexander: “Yesterday. Very noisy yesterday. The wind was high and they,
you could
really hear them.”
Tom Alexander: “Just a continual swish, swish, swish, swish, swish.”


Windmill developers say the sound is no louder than normal speech. But this noise is
different. It
goes beyond the frequencies of normal speech. The sound can travel long distances
through both
the ground and the air. They keep Virginia Alexander awake some nights.


Tom and Virginia Alexander’s son Kelly lives next door with his family. He calls
himself a
windmill victim. He has this advice for others:


“Don’t let them go in your backyard. There are places they can go. You don’t just
put those in
somebody’s backyard. I don’t think it’s right.”


A lot of people agree with the Alexanders. Even wind energy boosters concede that
location is
key to successful projects. David Johnson heads up the program for the state of
Michigan that’s
encouraging farmers to allow windmills on their land. He says turbines should be
constructed
where there’s lots of wind and few neighbors. But he says when people say ‘no’ to
windmills,
they should consider the alternative.


“So, does that mean that you should build another big coal-fired plant? Is that the
preferable way
of doing it with the global warming impacts and the mercury pollution and so on that
go with
that? Is that the choice that the public wants to make?


States across the nation are struggling to find the right balance between clean
energy and the
beauty of an uncluttered landscape. Few regulations are in place right now. More
and more,
communities will be facing the decision of whether clean energy and keeping farmers
on the land
is worth the price of adding wind turbines to the scenery.

Migrating Birds Hurt by Communication Towers

Every year, more than 5 thousand new communications towers
are erected throughout the United States. They’re needed for cell
phones,
television and radio stations and 911 networks. But at this time of
year,
these towers become deadly obstacles. It’s estimated millions of
migrating birds are killed each year when they collide with towers in
their
flight path. As the Great Lakes Radio Consortium’s Karen Kelly reports,
there’s a growing consensus that something needs to be done:
