- Hello and welcome to "In Wisconsin."

I'm Patty Loew.

This week, losing your voice could mean losing your job.

- I was really concerned that I wouldn't be able to teach anymore.

- See how a University of Wisconsin clinic gives hope to those struggling to be heard.

And feel the heat, as we take you inside a raging fire.

It's the stage firefighters fear most.

And from fire to ice.

Black ice.

- At this time of the year, we will get a lot of inquiries.

- It's so crystal clear that you can see fish beneath the surface.

And a preview of the new special called "Our Birds."

Next on "In Wisconsin."

- Major funding for "In Wisconsin" is provided by: the people of Alliant Energy, who bring safe, reliable, and environmentally friendly energy to keep homes, neighborhoods and life in Wisconsin running smoothly.

Alliant Energy, we're on for you.

And Animal Dentistry and Oral Surgery Specialists of Milwaukee, Oshkosh and Minneapolis.

A veterinary team working with pet owners and family veterinarians, providing care for oral disease and dental problems of small companion animals.

- We begin this week with something most of us take for granted.

Our voice.

For many professionals like me, losing your voice or coping with hoarseness is more than an inconvenience.

It can result in the loss of income, or even a career.

And you may be surprised to learn just how many people suffer from vocal problems.

There's a highly specialized clinic at UW Hospital that works with patients ranging from singers to everyday folks in Madison.

- Sarah Grodey is a teacher who works one-on-one.

She travels to the homes of special needs children like Ryan Schumaker.

It's a job that hinges on her ability to speak and sing.

♪ The wheels on the bus go 'round an 'round ♪ - I work with kids with a variety of needs, and I have to use my voice a lot.

- Grodey struggled since high school with hoarseness, at times completely losing her voice.

So far, she's undergone two vocal cord surgeries in order to continue working in the jobs that she loves.

- A couple of years ago, I was really concerned that I wouldn't be able to teach anymore.

My voice had really given out.

I was discouraged that I was going to have another surgery, and that may mean limited use of my voice.

- Then she heard of a clinic at University Hospital called The Voice and Swallow Clinic.

Among its services, is a form of physical therapy for the voice.

Clinic director Susan Tevo says voice problems like Grodey's are quite common.

- We know that 29% of the population will have a voice disorder at least once in their lifetime.

- After a physician ruled out disease like cancer, which requires surgery, a speech pathologist began voice therapy.

- When I first started in voice therapy, I didn't know what they were doing.

Different sounds, up and down.

It was like to use my vocal cords in a different way.

- Grodey's problem stemmed from allergies.

Another common health condition that causes hoarseness is acid reflux.

But many people simply talk in a way that irritates the vocal cords.

- His debut novel takes place in Minor Universe 31... - Anne Strainchamps is one of the voices heard on the Public Radio program, "To The Best Of Our Knowledge."

- My voice developed what I call a gravely sound.

It's hard to hear your voice sound ugly, or have the engineers say to you, "Can you project anymore?"

And you have to say, "No, (chuckling) I can't!"

- So, when someone is talking really deep like this and they're creating a lot of stress and tension here, that's going to be more likely to cause a problem with their voice.

- So, one of the things they had me do is hum, like this.

(hums from high to low tone) And pay attention to where I feel vibration.

They said when you can feel your teeth vibrate, stop.

That's my natural range.

If you said, where is your voice coming from?

It's not coming from here, it's all up here.

All of a sudden, that graveling sound was gone.

It was amazing.

- Close your mouth a little bit and go, mm mm mm.

- One of the high-tech tools used to diagnose voice problems is called stroboscopy.

Sarah Blakeslee is a speech pathologist at the clinic.

- Stroboscopy is a microphone that picks up the pitch of the patient's voice, and then synchronizes the strobe light to blink at just the right speed, so it makes it looks like the vocal cords are moving in slow motion, so you can get a little bit of a sense of how well the tissue is vibrating.

Sort of see how the vocal cords are closing.

See if there's any gaps anywhere.

See if they're vibrating symmetrically.

(humming along with piano notes) - 16-year-old Alyssa Yokum completely lost her voice after a cold.

Yokum was a singer and was in a hurry to get back on the stage.

- I like doing show choir and musicals and stuff.

So, it's really important to me.

- One-third come in after they get a cold.

- What happens is they get stuck in sort of this inappropriate pattern of muscle tension where you kind of get used to talking in this back, scratchy voice.

Then the cold goes away, and your muscles are kind of stuck in this pattern.

- If you've broken your leg, and you still run on it, you use other muscles to adapt, then you would have to learn how to use your leg the normal way again.

Same thing with a cold.

- ♪ on the bus goes... ♪ - From teachers to broadcasters, to the many non-professionals who struggle with their voice, the UW's Voice and Swallow Clinic offers hope.

- Voice therapy, it makes me really emotional, has helped me be confident and comfortable with my voice.

And I just don't have those problems anymore.

- The UW Voice and Swallow Clinic is one of the largest and oldest voice clinics in the country.

They see on average 600 patients a month from far away as India, Iceland, and England.

The help patients get at the clinic can sometimes prevent the need for surgery.

In any emergency, quick communication is key.

For firefighters, it could be a matter of life and death.

To understand that firsthand, we take you into the heart of a raging, smoke-filled fire.

This week, videographer Will Salzman continues his occasional series, "Unseen Places," to put you on the front lines as firefighters train in the Town of Springfield.

(fire crackling) - Take a look.

- Baptism by fire.

Tasting the heat.

Taking the shine off.

It's known by many names, but technically, it's called a controlled training burn.

It's a rite of passage that firefighters all over the world experience as part of their training.

It's this environment, the heat, the smoke, the chaos that helps train firefighters to prevent the most dangerous stage of a fire's life.

If unchecked, the temperature of a room on fire surpasses 1,200 degrees.

When this happens, everything, even the carbon monoxide in the very air itself, ignites.

It's the stage firefighters fear most.

It's called flashover.

- It's going to flash!

Hit it.

- The morning of the training burn begins with the briefing, where Assistant Chief Gary Gillitzer passes on details of the day's activities.

- This, we've got a burn event today; this, we've got to burn today.

- Once at the location of the planned burn, crews position the equipment.

A supply of water is established.

Hoses are run.

And the house is carefully prepared for the burn.

Before the fire is lit, everyone tours the structure one last time.

Exits and escape routes are pointed out.

- Okay, bedroom, bedroom.

There'll be no burns upstairs.

This is what is up here.

Okay?

- Now it is time for the firefighters to don their air packs.

It's called packing up.

The last step before entering the house is a buddy check.

Each firefighter has to be checked to ensure that no bare skin is exposed.

Finally, it's time.

Everyone is ready.

The fire has been lit.

And, the first attack team makes entry.

Now, we've all seen fires in movies, flames leaping and dancing in a perfectly clear room.

This is the reality.

It's incredibly hot.

It's dark.

And it's nearly impossible to see.

It is for this reason that thermal imaging cameras were created.

Not only do these tools show firefighters exactly where the fire is, they help them locate victims in a fraction of the time that it used to take.

In many ways, fire is a living thing.

It eats, grows, reproduces and breathes.

- It's puffing out of the back room.

It's coming and going.

Coming and going.

- A lot of time is spent during these burns, not only to learn to cope with the brutal environment, but studying how a fire behaves.

- You switch off.

Get out and switch out.

Get behind the line.

- Finally, when a fire has grown too hot for firefighters to safely attack it directly, Chief Aaron Harris calls for a technique called a blitz attack.

- Go at this from the original door... original door.

You're gonna have to knock the fire back out of the way.

Blue 20 10.

Now, now.

Blitz when you can.

- Many lessons are learned during these training burns, both technical and personal.

No one really knows how to attack a fire until they have done it.

No one really knows what they can face until they felt the heat.

It's only through intensive and realistic training that firefighters learn to control not only fire, but also their fears.

- A blitz attack is really an offensive attack.

You're going after it to knock it back to get inside.

We did it.

- We take you to fire to ice.

Black ice.

From blizzards to ice storms, old man winter zeroed in on Wisconsin this year.

And through it all, we discovered something unique.

A lake polished into a brilliant gem by strange weather patterns.

As part of our Quest environmental reporting project, we explore the phenomenon known as black ice with John Magnuson, UW emeritus professor of zoology and limnology in Madison.

♪ ♪ - So many people have noticed that the ice is so clear on Lake Mendota this year.

But, it's not usually crystal clear when you get out on walk on Mendota, but it is this year.

We often call this crystalline ice, which you can see here, black ice.

The ice isn't black.

It's like a windowpane.

It's transparent, so people see all sorts of things.

At this time of year, we'll get a lot of inquiries, like, "I saw this under the ice, what's wrong?"

"I saw this under the ice."

"Or, I found my anchor."

♪ ♪ Well, why do we have clear ice this winter when typically, we don't?

We had a little bit of rain, and a January thaw, and then a little bit of snow that was on top melted and got rained on and then that froze a new layer on top of the ice.

Again, it was ice rather than frozen slush that was forming.

♪ ♪ The word ice in Greek is crystal.

And it's spelled a little differently, but crystal.

You tend to think of glass crystal or something that's crystal clear.

Now, these bubbles happen to be from oxygen bubbles from photosynthesis of this algae before it broke loose on the bottom.

♪ ♪ Well in fact, the lake as you just discovered is active under there in the wintertime.

Lots of processes; lots of life going on.

So, when we study the lakes, we study them year-round.

♪ ♪ - That report was generated by our graphic artist, Jen Hadley, who discovered the black ice phenomenon while out skating with her daughter Sophie.

The report you just saw is part of a much larger multimedia partnership with the Wisconsin Educational Communications Board, Wisconsin Public Radio and PBS stations across the country.

The purpose is to highlight environmental reporting, spark discussion and inform.

Wisconsin Public Television, along with our partners, has developed a web site called "Quest Wisconsin."

Reporter Andy Soth shows us how it works.

We also wanted to tell you about another exciting project we've been working on.

♪ ♪ For more than two years, "In Wisconsin" reporter Jo Garrett and videographer Frank Boll have been working on a documentary special called "Our Birds."

It's an adventure that took them into every corner of our state and deep into Central America.

Jo joins us this week with a preview.

- Thanks, Patty.

"Our Birds" is a show that looks at the problems faced by what are called neotropical migrants.

Those are the birds like the Baltimore Oriole, that migrate from their wintering grounds in the southern hemisphere to their breeding grounds here in Wisconsin.

They face enormous challenges.

So, we wanted to examine the efforts of people in both hemispheres who are working so hard to save them.

People like Wisconsin conservationist Craig Thompson, who has an innovative approach to save the bird habitat in Costa Rica.

Thompson works as a regional land program supervisor... - Oh, my gosh!

It's a Swainson's thrush!

- ...for the Wisconsin Department of Natural Resources.

This is his beat: the Mississippi River side of the state.

- I got 'em.

- You've got 'em!

He knows birds and conservation.

And he's traveled the world in his time off putting the two together in a new way.

- We're calling it conservation birding trips.

So what we do is, we provide trips basically at cost.

So, we're offering bargain basement prices, but the catch is that every birder, every participant, that goes on these trips has to donate $500 per person to a non-profit conservation organization.

And of course, the primary emphasis of that is to save wintering habitat specifically for those birds that migrate from Wisconsin down to Latin America.

- Wintering habitat.

Home base, really, for these tiny birds for most of the year.

- It's the Philadelphia vireo.

- And different neotrops need different habitat.

Red-eyed vireos prefer living up in the canopy of the rain forest.

It's watery coastal mango forest for the Prothonotary warbler.

Weedy areas at the edges of agricultural fields for the Indigo bunting.

The Eastern phoebe likes to hang by rivers and the streams.

Places that are also valuable and vulnerable.

- The clock is ticking.

The population of Latin America is expected to increase by 100 to 360 million over the next 40 years.

That's a lot more people in a very finite land mass.

They need clothes.

They need food.

They need shelter.

And they're going to want all the things that we have in terms of lifestyle: televisions, washers, dryers, refrigerators.

The clock is ticking, and we really have a very limited window to try to protect these remaining big blocks of forest, so we can hang onto the birds that breed up in the States and then winter down here.

Every acre that we protect makes a big difference.

- We traveled to both Costa Rica and Panama to profile, not just Thompson's program, but also the work of scientists and conservationists in both those countries.

We captured some really fascinating information about Wisconsin businesses and non-profits who are sponsoring work down there.

- I understand these neotrops also face pressures here in our state, right?

- Oh, yeah, enormous obstacles, Patty.

It's a very tough situation for them.

One of the biggest problems that they face is the problem in migration of window collisions.

It's estimated that every year, up to a billion birds die from what are called window strikes.

It's a problem in Milwaukee, where Scott Deo, from the Wisconsin Humane Society is on the lookout for dead and injured birds, like a little Canada Warbler.

Is it dead or alive - Alive!

Fortunately, alive, which is wonderful.

- The little warbler Deo found is alive.

Deo bundles the bird into a simple paper bag.

It's dark and safe, and the bird won't injure herself if she flutters about and tries to fly.

And it's off to the Humane Society.

- Window collisions, we'll look for eye injuries head injuries, blood coming from the mouth.

You can see this eye is a little bit swollen.

It looks dehydrated, kind of droopy-eyed.

It's not open all of the way, like this one is.

I'm just testing to see how they bounce back into place.

If they are broken, they'll droop down, and they won't pop back into place like this one is doing.

He looks in good condition.

I'm not feeling any breaks in the wings.

- After assessment, it's time for a little re-hydration, and a warbler-sized amount of medicine.

- I'm just going to put it on the seam of the bill.

This helps with pain and swelling and inflammation.

- The same day as this rescue, Deo drove to Doctor's Park, north of Milwaukee, to band... - Okay, bud, be careful.

- ...and release four birds brought back to health after window strikes.

- Just roll him over there, Elizabeth, and let me get a leg.

Okay, there you go.

Be careful there, kiddo.

Don't you hit any windows.

Ah, success!

Wonderful!

Oh!

I hope they do well.

We gave them a send chance anyway.

There's 10,000 windows between here and where some of these guys want to be.

So, we're hoping that people will get involved, take action on their own homes and businesses to help these little guys make it.

- Just to let you know that little warbler did recover and was eventually released.

Turns out, she actually had a broken wishbone, which was healed up with care from the folks at the Wisconsin Humane Society.

And with any luck, she's on her wintering grounds in South America.

- I'm so glad that had a happy ending.

Jo, thank you so much.

I'm really looking forward to this report.

- Thanks, Patty.

"Our Birds" is scheduled to air on March 17th starting at 7:00 pm right here on Wisconsin Public Television.
