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.”

Ethanol Part 2: Widening the Dead Zone?

  • Farmer Laura Krouse says the ethanol boom has been great for corn farmers, who she says are finally getting a fair price for their corn. But she says she's worried that there's not enough being done fast enough to reduce the dead zone in the Gulf of Mexico. (Photo by Rebecca Williams)

Scientists are predicting the Dead Zone in the Gulf of Mexico will reach its largest size ever this summer. Fish and shrimp can’t survive in the Dead Zone. It’s believed to be mainly caused by fertilizer washed from farm fields across the nation. Rebecca Williams reports some scientists say demand for ethanol made from corn could make the Dead Zone even bigger:

Scientists are predicting the dead zone in the Gulf of Mexico will reach its largest size ever this summer. Fish and shrimp can’t survive in the dead zone. It’s believed to be mainly caused by fertilizer washed from farm fields across the nation. Rebecca Williams reports some scientists say demand for ethanol made from corn could make the dead zone even bigger:


(Sound of tractor raking hay)


“It’s the perfect Iowa day, you know?”


Laura Krouse is tearing apart a bale of hay to mulch her tomatoes.
She’s a thousand miles from the Gulf of Mexico. But she points out,
what happens on farms here ends up affecting life way down South:


“This watershed I live in drains 25% of Iowa. And we’re one of the
richest farming states in the nation – of course we have something to
do with it.”


By “it,” Krouse means the dead zone. All or parts of 31 farm states
drain into the Mississippi River, which empties into the Gulf.
Scientists point to nitrogen fertilizer used on farm fields as the main
cause of the dead zone. All that nitrogen causes an enormous algae
bloom. When the algae dies it drops to the ocean floor. Bacteria eat
the algae and they rob the water of oxygen.


This summer, the dead zone’s predicted to reach a record size. It could get as big as the state of New Jersey.


Laura Krouse has been trying to cut back her own role in the dead zone.
Five years ago, she added something to her farm that’s rare around here.
Krouse cut some of the tile lines that drain water from her farm, and
replaced part of her farmland with a prairie wetland. She says that
made her neighbors nervous:


“We just don’t see people taking land out of production in Iowa very
frequently.”


Wetlands like this one remove nitrogen from the water that flows from
farm fields.


It’s one of the things a government task force on the dead zone
recommended to cut nitrogen loading into the Gulf.


But instead of a big push to restore wetlands, the economic landscape
is changing in the other direction. Demand for ethanol has led to
historically high corn prices. And that’s encouraging farmers to grow
more corn. A USDA report says farmers have planted 14 million more
acres of corn this year than last year. It’s the most corn planted in
the U.S. in more than 50 years.


Laura Krouse says this is not good for the Gulf of Mexico:


“I’m concerned about all the extra corn because it requires nitrogen to
produce that corn and no matter how careful we are and no matter how
expensive it is which causes us to be more and more careful with
application, nitrogen as a molecule just wants to get away. It is
leaky.”


When it rains, nitrogen runs quickly from farm fields and gets into
creeks and rivers. The federal government’s task force on the dead zone has been trying to
tackle all this.


Don Scavia led a group of scientists advising the task force under the
Clinton Administration. The Bush Administration convened a new science
panel to review the original science panel’s work. Don Scavia says
since then, there’s been very little progress in shrinking the dead
zone, or what scientists call an area of hypoxia:


“In fact what we’ve seen in the last year is just the opposite with
this push towards corn-based ethanol production. Even acres that were
set aside into conservation are coming back out into production, into
corn, and the increased nitrogen load to the Gulf this year and the projected record
hypoxia is probably caused by this increased corn production.”


Scavia says if the dead zone keeps increasing, the Gulf shrimping
industry could collapse.


Ironically, the new science panel appointed by the Bush White House is
calling for even bigger cuts in nitrogen than the first panel appointed
by the Clinton Administration. They want to reduce nitrogen from farm
fields and other sources by 40 to 45 percent.


Don Parrish is with the American Farm Bureau. He says those reductions
are too much:


“Those are going to be really difficult and they could cause
significant economic dislocation at a time when I think we need to be
thinking about the products that agriculture produces, and those are
important.”


There’s no question corn for ethanol is at the top of that list right
now. Ethanol’s popular. It’s making farmers richer. It’s making the
chemical companies that supply nitrogen richer. The government task
force has to figure out how to cut back on all the nitrogen that’s
needed to grow all the corn… that’s needed for billions of gallons of
ethanol.

Farmers Respond to Peer Pressure

  • Farming is big business in America's heartland. Many farmers say they want to be left alone to run their farms the way they always have - and they don't want government regulators or researchers dictating to them. (Photo by Rebecca Williams)

Farm pollution is the biggest water contamination problem in the
nation. But government agencies often struggle with getting farmers to
use less polluting farming methods. Many farmers say they don’t want
outsiders telling them what to do. Rebecca Williams reports one
grassroots project is trying to encourage farmers to change, by relying

Farm pollution is the biggest water contamination problem in the
nation. But government agencies often struggle with getting farmers to
use less polluting farming methods. Many farmers say they don’t want
outsiders telling them what to do. Rebecca Williams reports one
grassroots project is trying to encourage farmers to change, by relying
on peer pressure:


(Sound of birds and buzzing insects)


The corn around here is way over knee high, and there’s a whole lot of
it. This is Iowa, after all. So, pretty much everyone farms corn and
soybeans.


But there isn’t as much farming happening today. Dozens of farmers are
hanging out by a creek that meanders through farmland. They’re
checking out the day’s catch.


(Sound of splashing around in bucket)


“Now there’s one really bright-colored southern red belly in here, kind
of the prettiest fish we’ve got in this stretch.”


Biologist Dan Kirby just used an electroshocker. It stuns the fish and
they float to the top of the water. Now that he can see them, he can
get an idea of how many fish there are and how big they are. The
farmers are watching closely.


(Farmer:) “That’s a real good sign to see them that big, at this
point?”


(Kirby:) “Yeah, especially the southern red belly – they do classify
them a little bit different, they consider them to be a sensitive
species, so it’s a good thing to have them there at that adult size,
for sure.”


That’s better news than they might’ve been expecting. This creek
running along many of the farmers’ fields is in trouble. It’s on
Iowa’s impaired waters list. In this case, that means the fish and
other aquatic life in the creek are not doing as well as they should
be.


“In some of these streams we have had some rough times. Chronic issues
where fish were not even getting to size they could catch them or else
were just plain absent.”


Dan Kirby says farm pollution such as excess fertilizer and soil
erosion from farm fields can harm fish and other stream life. That’s
the kind of thing that put this creek on the government’s watch list
three years ago.


One of the farmers, Jeff Pape, remembers hearing about that. For him it was a big
red flag:


“We knew there was an impaired waterway and it was running through some
of the land I rent and obviously I don’t want that to shine on me… I
didn’t want the DNR – not that they would or have the time to do
it, but I didn’t want them to come in and say hey, you will be doing
this, or you will be doing that.”


Pape says the fear of being dictated to by the government was a strong
motivator for him and a few of his neighbors. In late 2004, Pape
formed a watershed council with nine of his farming neighbors.


Now there are nearly 50 farmers in the group. Pape says there are some ground
rules: No finger pointing. And everyone gets equal say:


“That’s nice with this group – nobody’s telling them they have to do
anything – they do what they want when they want and that’s it. You
know, they don’t do any more than they want to.”


Pape says he’s proud of what he and his neighbors have gotten done.
They’re installing grass strips along ditches and creeks to filter
water rushing off fields. They’re putting in fences to keep cattle
from tearing up stream beds and banks. They’re being more careful
about how much fertilizer they apply.


Maybe most importantly, they’ve gotten a lot of their neighbors to join
them. Jeff Pape says cash incentives help – farmers are paid for the
conservation projects they do. It’s not as much money as some of the
government’s conservation programs, but it keeps the government out of
their hair.


Pape says this program works because there’s an even stronger
motivation:


“That guy’s looking over your fence – he sees you ain’t got a waterway
and you’re thinking about it, so that peer pressure thing does make a
difference too. You know everybody’s watching each other in this
watershed – not pointing fingers at nobody but everybody’s watching
each other and that keeps people on their toes – they want things to
look right, too.”


Other farmers here agree that a farmer-to-farmer project is going to be
much more effective than anything government regulators or researchers
say.


John Rodecap is with Iowa State University Extension Service. He’s
been helping these farmers clean up the creek. He says it’s remarkable
that more than half of the farmers in this 23,000-acre watershed have
signed on.


“The trials that they do, they talk about it at their coffee shop, they
talk about it over the fence… If the trial’s done 50, 60, 100 miles
away, that’s not good enough. They want to know how it’s gonna work on
my farm.”


Rodecap says if you see your neighbor making a change first, you’re
going to feel a little more comfortable giving it a try yourself. And
knowing your neighbor’s watching you over the fence… that’s a powerful
incentive all its own.

Armadillos Migrating North

Armadillos are moving out of Southern states and are pushing into the
Midwest in record numbers. Adam Allington reports:


Prior to the 1900s, armadillos were hemmed in by large rivers and open
prairie grasslands that weren’t suitable habitat. Now, all that’s changed.
Humans have cultivated the kind of woodlands and thickets that armadillos
need for cover.


Lynn Robbins is a biology professor at Missouri State University:


We’re getting a lot more records in central Illinois, we’re getting more records up into
Nebraska, we’ve found them now moving up into Indiana… have no records so far in
Iowa, I would not be surprised if somebody called and said ‘yes, they’re here.'”


Robbins says warmer winters and lower average snowfall are one hypothesis
for the expanding armadillo range. They are also prolific breeders and have
no natural predators.

Corporate Campuses Go Green

  • While new factories take up a lot of land, some corporations, such as GM, are setting aside acres for wildlife on corporate campuses. (Photo by Dustin Dwyer)

About a quarter of all private property in the
U.S. is owned by corporations. In the past, many
companies have gone to great expense to maintain
their property with manicured landscaping and green
lawns. Now, as environmental issues are becoming an
important focus in the business world, more
corporations are turning their land into wildlife
habitats. As Gretchen Millich reports,

About a quarter of all private property in the
US is owned by corporations. In the past, many
companies have gone to great expense to maintain
their property with manicured landscaping and green
lawns. Now, as environmental issues are becoming an
important focus in the business world, more
corporations are turning their land into wildlife
habitats. As Gretchen Millich reports,
they are finding it’s good for the environment and
it’s good for business:


Setting aside land for wildlife is becoming a big trend among
corporations in the US. For example, near its plant in Muscatine, Iowa,
the Monsanto Company set aside a 500-acre sand prairie. It’s home to
some rare species, including the Illinois mud turtle. Just outside of
New York City, Exxon Mobil is protecting 750 acres as a habitat for
birds like wild turkeys and wood ducks.


Bob Johnson is president of the Wildlife Habitat Council.
The council brings together businesses and environmental groups to
conserve and restore natural areas. His group has helped set up
hundreds of wildlife preserves at corporate facilities:


“Most of our members are not recognized as being very green and I think
that is really changing now because many companies are trying to find
ways of being a lot more conscientious about materials and energy. But
the real bottom line is habitat. Habitat is the greatest factor in the
control of the decline of species on the planet and I think companies
are realizing this is important for them to do.”


Johnson says there are lots of advantages to being green in the world of
business. Studies show that employees are happier and more productive
when they work for a business that shares their values. Also, it’s much
less expensive to maintain a wildlife habitat than to fertilize and mow
several acres of grass.


Bridget Burnell works at a new General Motors assembly plant near Lansing, Michigan.
Burnell is an environmental engineer. She oversees 75 acres on the factory grounds
that’s been set aside as wildlife habitat:


“What we’re walking up to right now is the first major wetland that you
come across. This is what all the employees can see as they are
driving along the main road east of the plant.”


It’s an unlikely spot for a wildlife refuge: on one side a sprawling
automobile factory, on the other, the intersection of two major
highways. It’s noisy, but still somehow serene.


Birds, turtles, muskrats, and frogs all live here undisturbed. A great
blue heron is flying over the wetland and in the distance, we see three
whitetail deer. Burnell says on nice days, teams of employees come here
to take care of the grounds and sometimes they work with community
groups:


“We’ve had about 20 events this year that we’ve had different community
organizations out here. Some of it’s directly related to educational
type things, like learning about the wetlands and the prairie
and different types of habitat. Others are specific to a particular
project, maybe wood duck boxes or song bird boxes, that type of thing.”


This factory is the only automotive plant to receive certification from
the US Green Building Council for Environmental Design and Construction.
GM saves about a million dollars a year in energy costs and more than 4
million gallons of water. And although there’s no direct cost savings on
a wildlife habitat, GM is finding that preserving natural areas can
improve the company’s image in the community, and also with its
customers and investors.


Bob Johnson of the Wildlife Habitat Council says these wildlife projects
are attractive to green investors, who choose stocks based on how a
company deals with the environment. He says some investors believe that
environmental responsibility is a reflection of how a business is
managed. And a lot of that information is available on the Internet:


“The individual on the street can do that today. They can evaluate this
kind of information and make judgments. So I think people are looking
for ways of distinguishing where they are placing their resources.”


Johnson says since corporations are the largest group of landholders,
they’re in a good position to slow down the fragmentation of wildlife
habitat. He says corporate leaders are discovering that with a little
effort, they can win friends and gain a competitive advantage.

Windmills Generate Jobs and Power

U.S. demand for clean energy is growing fast. In fact, wind energy developers are ordering so many windmills, they’re running into a supply problem. Windmill manufacturers overseas have been shipping their products to the booming U.S. market. That’s already created some jobs, and now there are plans to build factories to produce windmills here. It’s all happening in spite of inconsistent federal support. Stephanie Hemphill reports:

U.S. demand for clean energy is growing fast. In fact, wind energy developers are ordering so many windmills, they’re running into a supply problem. Windmill manufacturers overseas have been shipping their products to the booming U.S. market. That’s already created some jobs, and now there are plans to build factories to produce windmills here. It’s all happening in spite of inconsistent federal support. Stephanie Hemphill reports:


At the Duluth Port Terminal, the BBC India is tied up to the dock. Two giant cranes slowly lower a silvery propeller onto a waiting truck. The blade is half as long as a football field. The extended bed of the eighteen-wheeler isn’t long enough to hold the entire length. A padded steel structure cradles the narrow end above the ground. There are 66 blades on the ship, three blades for each of twenty-two towers.


“The three blades will bolt into a hub, and then the hub attaches to the nacelle, the generator package, that’s the actual turbine, and the nacelle sits on top of the tower.”


Andrew Holdrup is the port captain for the shipping company. He was here in Duluth a year and a half ago, when the port handled its first ever shipment of windmills.


Holdrup says the demand for windmills is huge in the U.S.


“We have four ships; all they do is run from Denmark to Houston with Siemens windmills. We discharge them in Houston, the ship sails back empty to go pick up the next lot. Multiply that by all the other ports, and all the other windmill manufacturers, and it’s a huge business.”


It’s great business for Duluth’s port. Unloading the windmills requires iron workers to cut the steel where the pieces have been welded to the ship, and crane operators, and longshoremen. And truckers are staying in town waiting to pick up their loads. They’ll haul the windmills to wind farms being built in Mower County, Minnesota, and Oliver County, North Dakota. The port has also handled equipment for wind farms in Manitoba.


The boom in wind was primed in the early 1990s, when Congress set up a production tax credit for wind power. It allows a 1.9 cent-per-kilowatt-hour tax credit over ten years, for electricity produced by wind.


But the tax credit only runs for two years at a time. Ron Johnson is in charge of marketing for the Duluth Port Authority. He says that on-again, off-again approach has made it hard for businesses involved in wind energy to plan and grow.


“It’s kind of start up again, stop, start up again, stop. If you’re a trucking company with these specialized trailers, you don’t want to go out and buy fifty more of them if there’s a chance your whole fleet’s going to sit until Congress decides what to do.”


Johnson says there’s a lot of support in Congress for the tax credits, and he expects them to be renewed.


Steve Stengel works for FPL Energy, the company building the wind farms where these windmills are headed.


“It is part of the business, we understand that. And it does cause kind of starts & stops, if you will.”


But he says it’s possible to work around the periodic breaks in the tax credit because it takes a long time to plan a wind project anyway.


“Permitting issues, land lease issues, transmission issues. We have to plan as if the tax credit is going to be there.”


In fact, wind is growing dramatically in spite of the iffy nature of federal support. Several states now require utilities to invest in renewable energy, or offer incentives for wind power development. And as the cost of fossil fuels goes up, the relative cost of wind goes down.


It all adds up to a lot of demand, and recently, tight supplies.


The American Wind Energy Association’s Susan Sloan says orders are already in place for 2008 and beyond.


“Because of this boom and bust cycle but also because of this new acceptance of wind, we are seeing a tighter supply, and we need to have the manufacturing capabilities catch up.”


And that’s what’s happening.


It took two weeks for the Siemens windmills to sail from Denmark to Duluth. Now the company is building a factory in Fort Madison, Iowa. Siemens says it will employ 250 people, and start producing in the first half of 2007.


And in Pipestone, Minnesota, Suzlon, a company based in India, is about to start producing three blades a day, and the nosecones to go with them. The company plans to manufacture the electronic controls, and eventually employ up to 300 people. Suzlon says it has orders for the next two to three years.

US demand for clean energy is growing so fast, supplies of generating systems are getting tight. Stephanie Hemphill reports on a challenge that could lead to more jobs in the US:


Overseas manufacturers of wind generating systems are shipping them here as fast as they can. Now, several companies are building wind generator factories in the US.


Siemens is building a plant in Iowa. Suzlon is about to start production in Minnesota. Plants in Texas produce blades and towers.


It’s all happening in spite of inconsistent federal support. A production tax credit is in place, but it expires every two years.


Ron Johnson is with the port of Duluth, which handles windmill imports. He says the on-again, off-again support makes it hard for companies to plan and grow.


“Well, the deadline’s coming at the end of next year, and people are planning their projects, so we’re all anxious to see what Congress does.”


The American Wind Energy Association says producers are installing enough wind power this year to power the entire state of Rhode Island.

Untapped Power in Offshore Wind Turbines?

  • Developers want to put wind turbines in offshore locations like Lake Ontario and off the coast of Massachusetts. (Photo by David Orsborne)

The U.S. Department of Energy wants 20 percent of the country’s
electricity supply to eventually come from wind power. Some of that
power could come from wind turbines located on the water. The
GLRC’s Chuck Quirmbach reports some power companies are hesitating:


Until recently, the strength of the wind on the water was mainly of
interest to the shipping industry, anglers, and to people who like
to sail.


(Sound of sail ruffling and folding)


Lee Konczak is folding up the sail on a small sailboat that he often
takes out into Lake Michigan. Konczak says he likes the serenity of
riding on the wind and the beautiful view from offshore. Even so, he
says he wouldn’t mind if the view included a few wind turbines:


“With energy certainly being at the top of the news practically on a
daily basis right now, and with limited resources, I think an
experimental kind of thing with wind turbines would be excellent.”


Some wind power companies are planning more than a small
experiment. An effort is underway to put up 140 wind turbines in Lake
Ontario and another developer wants a wind farm off the coast of
Massachusetts. The industry would like to develop more projects. It
says the US is behind some European countries when it comes to
going offshore for wind. Compared to the US, European countries are
short on fossil fuel supplies and they don’t have as much land. So
they began placing turbines offshore a few years ago.


John Dunlop is with the American Wind Energy Association. He says the land-based
wind turbines in the US and Canada are important but often trigger local
disputes over new overhead transmission lines. Dunlop says lake-based
wind turbines would avoid some political squabbles by being close to
many cities:


“We enjoy living next to water, so consequently our population centers
tend to be close to the water which means a lake-based installation
may be no more than 10-20 miles away from that load center. Now, to get
that energy, that electricity from that wind project back to the city
you do need to have underwater cabling, but that’s a fairly common
technology so that’s not a huge impediment or a huge cost.”


Several environmental groups are getting on board with the idea of
putting wind farms in waterways. Charlie Higley is with the Citizens’
Utility Board in Wisconsin. He says there are already many coal and
nuclear plants near the water:


“Both of those have huge environmental and economic costs
associated with them, so we’re supportive of the development of
wind, not only on land but we really think the time is now to
start looking at developing wind resources on Lake Michigan.”


Higley acknowledges some people may not like the look of wind
turbines if they’re installed within view of the shoreline. Other
supporters concede there also needs to be more study of wind speeds
over the water. They also say there needs to be a cheaper way to fix
turbines that break down in waters dozens of feet deep.


Walt Musial helps oversee offshore wind projects at the National Renewable Energy
Lab. He says getting to a turbine in water is no easy task:


“You can’t drive a truck, so you have to drive a boat, or perhaps a helicopter like they do
in Europe. These add costs as well, and so these methods of accessing turbines have to be
developed and minimized.”


Still, Musial says because the Energy Department’s long-term goal is
to promote more wind production, he predicts some of that wind power
will come from offshore. But for now, the uncertainties have many
power companies rooted in inland turbines.


Kim Zuhlke is with Alliant Energy. He says his firm prefers a place
like Iowa, where there are already 800 wind turbines and a
desire from public officials to have more:


“You couple the acceptance, the economic growth, existing
transmission, all of those things together make it a logical place
for us to go.”


Still, Zuhlke says offshore wind turbines in the U.S. may become
a reality. He says engineers have to perfect a turbine that provides a big
enough payback for the additional expense of putting something way out in
the water.

Home Renovation Turns Up Surprise for Science

Last summer, he learned that a family in his old neighborhood was renovating a farmhouse. It had belonged to Ralph Handsaker. When Handsaker died thirty years ago, the house was boarded up and left alone.


“… And when the family started renovating this old farmhouse for the great-great-grandson, John Handsaker, along with a number of old animal mounts and interesting things, there were these two large chests with about fifteen drawers each, that were totally filled with little sets of wild bird eggs.”


The smallest egg, from a hummingbird, was small enough to sit on top of a dime. The biggest was an ostrich egg almost six inches long. Some were creamy white, others were speckled, others streaked with color like a Jackson Pollack painting.


There were more than 3,600 eggs, representing more than 400 species of birds from all over the world. And they were in perfect condition.


“Each set of eggs was very neatly labeled with information about the day they were collected, who the collector was, and information about the habitat where the egg was collected. Some of these eggs went all the way back to 1875, and they were collected by over three hundred different people from all over the world.”


This is how nature-lovers expressed their passion in those days. They called themselves oologists. They kept their eggs in drawers lined with cedar sawdust to protect them from insects. They also kept meticulous records.


“So the scientific data was very high quality among these avid collectors. So even today, these provide very important nest records for birds that are now gone. Like in my home county of Story County, Iowa, there were Marble Godwits, King Rails, Prairie Chickens, and Bobwhite Quail, and those are all gone now.”


The birds disappeared as people turned prairies into farms. But Carrol Henderson says the records in the bird collection provide detailed information about where and when they nested.


“And another intriguing thing is that when these people blew out the eggs, there was still a lining of the egg white or albumen left inside the egg. And that still has the original DNA genetic material, so it actually would be possible for scientists to do DNA analysis of these eggs to take a look at how they may compare with birds nowadays.”


Henderson says these collectors didn’t think they were harming the birds. That’s because if their eggs disappear, most birds will lay another set. But competition for the eggs of rare birds was disastrous.


“One person in Philadelphia had a collection of over seven hundred Peregrine Falcon eggs. Another Peregrine egg collector went to the same cliff and collected all the eggs from the Peregrines every year for 29 consecutive years. And then finally the nest was abandoned. And he said it was abandoned due to encroaching civilization. That was where egg collecting really had something of a dark side.”


Eventually, attitudes began to change. In 1918, the federal government passed the Migratory Bird Treaty Act, to protect birds and eggs. But the government let three collectors keep on collecting. One of them was Ralph Handsaker. So his collection goes into the early 1950’s.


Carrol Henderson says there’s a lot to learn from these eggs. One of the best lessons is about human responsibility. Henderson says people these days enjoy nature differently than they did a hundred years ago. But we can still learn something from earlier methods.


“It’s like a little time machine: stepping back in time, seeing what was here, and then looking at what’s changed, and what does that mean for our own conservation efforts, how can we do a better job today to collect information and use that for our own conservation of wildlife species?”


Carrol Henderson’s article about the Handsaker egg collection will appear in the October issue of Birders World magazine. The Handsaker family is planning to donate the collection to a major university.

Farmers Upset With Opportunistic Cranes

At this time of year, one of the nation’s most exotic
birds is nesting, and many wildlife lovers are rejoicing. Once
close to extinction, the Eastern population of sandhill cranes
has grown dramatically. In fact, their numbers are so big that
they’re becoming a problem in some places – and there’s talk of
starting a hunting season for cranes. The Great Lakes Radio
Consortium’s Sandy Hausman has the story:


(Sound of marsh and birds)


It’s a cool spring morning, just before dawn. Brandon Krueger is watching a stretch of marshland along a country road in Central Wisconsin. Krueger works for the International Crane Foundation. He’s taking part in the annual Midwest crane count. Celebrating its thirtieth year, thousands of volunteers have fanned out across parts of Wisconsin, Michigan, Minnesota, Illinois and Iowa to look and listen for sandhill cranes.


“It’s a great sound to hear when you’re waking up. This is usually the earliest that I ever get up during the year. It’s a real struggle, but it can be worth it – for some of the things that you hear and the opportunity to see cranes.”


(Sound of crane call)


Krueger hears a breeding pair a half a mile away – exchanging what’s known as a unison call. The birds are big – up to five feet tall. A hundred years ago they made easy targets for hunters. In the 1930’s, naturalist Aldo Leopold lamented the loss of cranes – nearly hunted to extinction in Wisconsin. He knew of only 25 breeding pairs of sandhills in the state. But the federal government made it illegal to hunt cranes, and the state started working to restore bird habitat. Today, crane lovers celebrate an impressive comeback.


“I’ve talked with our leading field ecologist and he’s estimated upwards of forty-thousand sandhill cranes in the Midwest area.”


This year’s crane count is still being tallied, but Krueger heard nine birds and saw three flying by.

In the county next door, Troy Bartz claims to see many more birds than that on a daily basis.


“I’ll come home and it’s nothing for me to see two, three-hundred cranes in a field in one crack.”


Bartz has been farming for 13 years – growing corn, soy beans and alfalfa on nearly a hundred acres near Nina Creek.


(Sound of plow)


“Plants started disappearing out of the field with crane tracks right next to them. They go right down the row and they pull the shoots out of the ground and eat the kernels off the roots. I lose thousands of plants every year.”


The International Crane Foundation says damage in Wisconsin alone could total $100 million, and for family farmers, a year’s profit could be lost.


Bartz: “On the small acreage that I’m tilling, you can’t lose thousands of plants and not have some kind of an impact. That’s hundreds and hundreds of bushels I’m losing.”


Hausman: “And what’s the cash value on that?”


Bartz: “I figure anywhere between two to three-thousand dollars minimum every year.”


Hausman: “So what do you think the answer is?”


Bartz: “Shoot ‘em.”


Hausman: “Really?”


Bartz: “Yeah!”


There is some talk of having a hunting season for cranes, but that would require approval from the U.S. Fish and Wildlife Service, and many critics say the eastern population of sandhills is too small to permit hunting. The Wisconsin Department of Natural Resources says there are alternatives for farmers – machines called banger guns that make explosive sounds every few minutes. Troy Bartz’ neighbor, Mel Johnson, tried that, but found the birds quickly got used to the noise.


“The DNR warden brought the guns out. He said the best way is to mix a few regular shells in with it, he said, because it won’t scare ‘em away, the guns. He’s been taking them out for years, and he said they won’t scare any wildlife away – them guns.”


They’ve also tried scarecrows and colored ribbons but they didn’t work either. Farmers have had success with a product called Kernel Guard – a pesticide that made corn seeds taste bad to cranes, but this year the manufacturer stopped making it because one of its active ingredients can be toxic. Crane advocates are now asking the EPA to allow use of another chemical that’s already sprayed on golf courses to repel geese, but approval is not expected this year.

So crane lovers are keeping their fingers crossed – hoping farmers won’t be breaking the law by shooting the birds.
