The push is on to find more energy in
western states. And wildlife experts are trying
to figure out how some rare birds will react to
the increase in mining and gas exploration. Bob
Beck reports biologists studying sage grouse are
introducing new sounds into their research:

Gail Patricelli is a researcher from the University of California at Davis. She studies the
mating habits of birds. And she says the habits of the sage grouse are the most
interesting. The males gather each spring on their traditional mating grounds,
known as a lek.

“The males gather during the spring, puff up and strut around. The females come
down to the leks during their breeding season, to pick
a mate. So they basically comparision shop. You will see females move along the lek,
sometimes by themselves, sometimes with big groups of females. But then they pick who they are
gonna mate with, they mate with them, and then they leave. And that’s the end of their
relationship.”

Beck: “What’s odd about this, is this all sounds vaguely familiar.”

Patricelli: (laughs) “A lot of people say that, but humans are very different. It’s sort
of analogous to a singles bar where people are just going to hook up.”

Patricelli watches and listens to these birds at a mating ground in Wyoming. She’s
learning how males get the attention of females.

“They have some particularly cool behaviors where they produce a sound that
radiates from vocal sacks on their chests – which are very bizarre looking
structures. But the sound comes out of the vocal sack, so the male has to aim the
sound appropriately at the female in order to impress her to mate.

So it’s not just his ability to
have the biggest, loudest, flashiest signal, but also to actually aim it appropriately at the
female. He has to know how to put on a good show, but respond appropriately and
be sensitive to what the female is doing.”

But the search for more energy is bringing new gas drilling and big trucks closer to
sage grouse mating grounds. This is happening at the same time the birds’ numbers
are declining. Researchers’ fear is the noise from energy development is disrupting
the sage grouse’s ability to hear each other, which is critical.

(truck sounds)

To find out, Patricelli is introducing recordings of gas rigs and trucks into her
research. She wants to see if sage grouse can adapt to the noise.

“So, there’s things that a lot of animals do to deal with noise in the environment.
And sage grouse may or may not be able to do that. They are not the brightest
(laughs) birds in the world.”

Wildlife Biologist Stan Harter works for the Wyoming Game and Fish department.

He’s watching the research with interest. Biologists worry that the birds are leaving
their mating grounds, trying to get away from the noise. His fear is that if the birds
are relocating they might be putting themselves at risk.

“In my mind, the birds can maybe move over here and strut okay, but are they
getting good nesting conditions over there? Maybe not. Is there a way we can allow them to co-exist more friendly?”

Harter openly admits that the sage grouse has declined in the West to the point
where it could show up on the endangered species list. If that happens, it could shut
down major portions of the state’s important energy economy. Similar to how the
spotted owl shut down logging in the Northwest.

So, wildlife officials are trying to find ways to make the birds and energy
development co-exist. They’re hoping that Patricelli’s research will guide them, not
just in reducing the noise, but in developing a plan to protect the sage grouse
population into the future.

Harvesting the Wind (Part 1)

  • Wind turbines can be both a blessing for farmers, as a source of extra income... and annoying to the neighbors. (Photo by Lester Graham)

Wind farms of huge turbines are springing up along coastlines,
windy ridges and blustery farmland. Most of us see them from a distance.

Wind farms of huge turbines are springing up along coast lines, windy ridges and
blustery
farmland. Most of us see them from a distance. The Great Lakes Radio Consortium’s
Chris
Lehman recently visited some of them up close… and has the first of two reports on
wind energy…


If you can imagine the sight… there are 63 wind turbines scattered across the
prairie farmland,
their huge blades sweeping around, capturing energy from the wind. Each turbine is
213 feet
high. You can see them from miles around. But it isn’t until you stand directly
underneath the
80-foot long blades as they rotate in the wind that you begin to appreciate their size…


(sound of wind from underneath turbine)


“This is probably a typical day. They’re probably producing at about 30 percent of
what they are
rated at, and probably on average, for a year, this is what you’d expect.”


Christopher Moore is Director of Development for Navitas Energy. The Minnesota- based
company opened the Mendota Hills Wind Farm in northern Illinois just over a year ago.


Q: “What are some of the highest levels that you’ve reached?”


“Each turbine is capable of producing 800 kw, and there are times when we’ve had the
windfarm
working at about maximum.”


Moore says the Mendota Hills Wind Farm produces enough electricity to power about 15-
thousand homes per year. It’s the first wind farm in the state of Illinois.


Brian Lammers is a Project Manager for Navitas Energy. He says the location is
ideal since it’s
windy here nearly all year long…


“The wind here is more robust in the fall, winter and spring. So we have more
production during
those months than we do during June, July, August.”


Unfortunately, the summer months are the months that most often experience peak
demand for
electricity. Because of that, and because it takes so many windmills to generate
lower amounts of
power, it’s unlikely that current wind energy will completely replace fossil fuel
generated power.


(sound of turbines)


On the flat prairies of Illinois, the giant turbines are the tallest structures for
miles around. You
begin to wonder about things like lightning strikes…


“We might have experienced one or two last year. The turbines are protected from
lightning. The
entire wind farm is grounded, so if there is a strike typically it will just be
grounded down to the
ground grid. There’s typically no long-term damage associated with a lightning
strike. But as you
can imagine, they’re the tallest structures around so there are periodic lightning
strikes.”


Q “What about a tornado? This is tornado country…what would happen if one came
through
here?”


“I don’t know. These turbines are built to withstand everything but a direct strike
from a tornado,
so I think the same thing would happen to a wind turbine that would happen to any
large
structure if they were struck by a tornado. You’d probably have some significant
damage.”


(fade up sound inside turbine)


Inside the turbine, there’s a distinct hum as the blades whirl away at the top of
the hollow shaft.
It’s about ten feet across at the base, and a metal ladder allows anyone brave
enough to climb all
the way to the top.


Despite the hum of the turbine’s blades up close, the sound fades away just a few
dozen feet from
the tower. But noise isn’t much of a concern for this wind farm. It’s in the
middle of a soybean
field and there are no neighbors nearby.


Noise is just one of the aesthetic concerns for neighbors of wind farms. Appearance
is another.
The Mendota Hills turbines are coated with a special paint that appears white in
bright sunshine.
But when the sun’s not out, the turbines appear grey, and seem to blend in with the
cloud-covered
sky.


Dennis Cradduck has 19 of the turbines on his corn and soybean farm. He says the
wind farm
hasn’t been a problem. Of course, he’s getting paid by Navitas for allowing the
turbines on his
land. But he says the wind farm has led to an unexpected benefit: getting to meet
people from
across the country who pull off the highway for a closer look…


“We get people almost on a daily basis that drive by on the interstate and see them,
and stop and
want to look at them, and they’re amazed at them, and most—about 99 percent of them
have been
positive comments. In fact, one fellow from North Carolina stopped the other day
and said ‘I wish
we’d build more of these around the country because we need renewable energy.'”


The prospect of more renewable energy is appealing to most environmentalists. But
some worry
that wind farms can be deadly to birds. A study by the National Wind Coordinating
Committee
found that wind turbines kill an average of two birds per year.


Another concern is that windmills disrupt the scenery. But the only view around
here is farmland
as far as the eye can see. And on this brisk day, it isn’t just corn and soybeans
being harvested: it’s
the power of wind.
