With more than 7600 breeding pairs in the continental United States alone, the
American Bald Eagle has made a remarkable comeback. A new proposal to remove the
bird from the Endangered Species list is expected soon. But that means removing a
powerful safety net that can affect future research, monitoring and habitat protection.
The Great Lakes Radio Consortium’s Sally Eisele reports:


In the history of the Endangered Species Act, only a dozen or so of the more than 1200
plants and animals listed as threatened or endangered have actually recovered. The eagle
may be the latest to join that little group.


(Young birder: “I see a big birdie…”)


This is a pretty unlikely spot for an eagle — a manmade wetland by a landfill in a busy
airport flight path on the outskirts of Detroit. But state wildlife biologist Joe Robison
shows this young visitor the bulky nest across the marsh where two adult birds are
teaching their gangly fledglings to fly.


“Something just landed in the tree out there. Oh. That’s the other juvenile. This is the
first time I’ve seen them flying this year. They look like they’re flying good though.”


These birds are among more than 400 pairs in Michigan monitored by state and federal
wildlife officials. The eagles are banded, the nests are watched and when a bird dies it
ends up in the freezer of wildlife pathologist Tom Cooley.


(sound of Cooley opening the freezer)


“Lots and lots of ’em. You can see that one was a road kill along I-75…”


Right now, Cooley’s freezer is brim full of dead birds stacked like frozen Thanksgiving
turkeys in plastic bags. Road kill has become the leading cause of death among eagles
he examines, but Cooley says they still investigate suspicious looking deaths for the
heavy metals and pesticides—like DDT—which once caused the eagles’ demise.


“Birds that kind of send up a red flag to us are adult birds that are in poor condition and
you don’t see a reason why they could be in poor condition. Those are the ones that we
especially look at for pesticide analysis because there are still the organochlorines out
there. The DDTs are still picked up by eagles or still contained in eagles. Those
pesticides can cause real problems for them and actually kill them.”


Cooley sends tissue samples to another state lab for analysis. But the testing is
expensive. And with the eagle on the way to recovery, it’s not as urgent. Right now, he
says all the samples he sends are being archived—shelved basically. That means the
testing won’t be done until the money is available.


“I never like archiving anything if I can help it. You’re probably not missing anything
but that kind of data is always nice to have if you can get it right away and look at it right
away.”


The question is, if it’s hard to get funding for monitoring and testing now—while the bird
is still on the Endangered Species List—what happens when it’s taken off the list? The
reality, say state and federal wildlife experts, is that budget priorities change as a species
recovers. Ray Rustem heads Michigan’s non-game wildlife program.


“There’s not enough money for every species. So you try to take a species to a level
where you feel comfortable with and you take money and apply it to another species to
try to recover.”


The federal Endangered Species Act requires the Fish and Wildlife Service to monitor
what it terms a delisted species for five years. After that, responsibility largely shifts to
the states. That concerns groups like the National Wildlife Federation. Attorney John
Kostyak questions whether states can really afford to protect fragile species and their
habitat over the long term.


“That’s going to be an issue with any delisting. A tough question that we’re going to
always be asking is: all right assume you go forward with delisting—how are you going
to be sure the species doesn’t turn right around and go back toward extinction again?”


With some species, that means habitat management. With others, like the recovering
gray wolf, it means public education—teaching people not to kill them. With the eagle, it
means ensuring that the birds are not threatened by the pesticides, heavy metals and
newer chemicals that contaminate the fish the eagles eat. Because of the bird’s
importance as an indicator species, Fish and Wildlife biologists are hopeful banding and
testing programs will continue after delisting. But it will likely mean finding new ways
to pay for them.

A new study finds the economic impact of birders is significant. Bird watchers spend billions of
dollars across the nation. The Great Lakes Radio Consortium’s Lester Graham reports:


Bird watching might not be the first thing that comes to mind when you think about dollars spent
on outdoor recreational activities. But, because so many people birdwatch – 46-million – the
economic impact is substantial.


According to a first-of-its-kind report by the U.S. Fish and Wildlife Service, in 2001 bird
watchers spent 32-billion dollars on gear such as binoculars, travel, food and big-ticket items such
as canoes, cabins and off-road vehicles – all to watch birds. The government says that generates
85-billion dollars in overall economic output.


In determining who was actually a birdwatcher, the report did not count people visiting zoos or
those who just noticed birds while visiting the beach. To be considered a birdwatcher in the
economic report, only people who took a trip for the purpose of watching birds or those who
closely observe or try to identify birds around their house were counted.

Interview: Feathered Friends Return

It’s no wonder the International Migratory Bird Day is held in the month of May. This is the time
when trees in the Great Lakes states leaf out and provide a welcome habitat to birds returning
from their southern dwelling spots. The Great Lakes Radio Consortium’s Jim Blum decided to
venture beyond the backyard to see who’s back:


Blum: Take a stroll into a forest and you may notice that trees have greened out this month.
There are thick canopies overhead that weren’t there just a week or two ago. Naturalist Dan Best
says, that times out very nicely for returning migratory birds.


Best: That’s right. A few warm days and the leaves just explode out of the buds. And we have
full leaf-out already. May is just an amazing month. You still have the wildflowers, lots of
wildflowers. And well, Jim, what do you hear?


Blum: Well, certainly a parade of birds that I didn’t hear a month ago. The nuthatches and the
chickadees are still here, but who’s joined them?


Best: Lots and lots of birds. New arrivals here. We have thrushes and warblers and vireos and
tanagers, flycatchers – a tremendous variety of birds that have come to us from their wintering
areas in Latin America. That is South America, Central America, the Caribbean nations. These
birds have made their way, many of them traveling at night, using amazing means of navigation.
They’re using celestial navigation, that is, using the stars. They’re using perhaps the earth’s
magnetism, sensitivity to polarized light, a variety of different means to make their way
thousands of miles over land and ocean to return here to our forests to nest.


Blum: Why May, why now, why so many?


Best: Well, let’s take a walk over to some of these leaves, and no matter what kind of tree you’re
looking at here, what do you notice on these leaves?


Blum: Well, it seems as if several of them have little chew marks or holes.


Best: That’s right, holes. And no sooner does a leaf out, then the salad bar is served for
hundreds of different kinds of caterpillars, whether they be butterflies or especially moths. Their
hatching of these eggs of these caterpillars is synchronized with this leaf-out.


Blum: So, apparently there are many visitors to this buffet, but who, what, and where?


Best: Well, ok. Let’s listen here. (bird chirps) Hear that over there? That’s a hooded warbler.
(bird chirps again) Yeah, there it goes. Now that one will tend to stay low. Oh, the male might
go up a little higher to sing to announce its territory, but generally it’s gonna forge in this shrub
layer in the lower part of the forest.


Blum: (another bird chirps) Now what was that?


Best: Well, I can hear a nice warble up there. That’s the rose-breasted grosbeak. They all
spend most of their time in the understory – that’s about halfway up in this mature forest we’re in.
And then listening a little higher above us, I can hear that nice hoarse, robin-like song of the
scarlet tanager. And I’m even picking up the cerulian warbler, and a little bit of the hoarser vireo
sound, as well as the yellow-throated vireo, and those birds like to stay high up in the canopy.


Blum: So in order for this forest restaurant, if you will, to accommodate so many different
customers, it needs different stories.


Best: That’s right. These birds are here because of the big insect menu that the forest has to
offer. And they’re not fighting for the same seat at the same table because they’re distributed in
these different levels of the forest.


Blum: So if you’re talking about a canopy, an understory, and a shrub layer, you’re indicating a
mature forest.


Best: That’s right. That’s a characteristic of a mature and old growth forest is it has these defined
layers. This kind of habitat, these large tracts of mature forests are getting harder to come by, as
the large trees are logged out, or even worse, these remaining forest tracts are continually
fragmented into smaller parcels, which are less suitable for this big diversity of forest-nesting
birds.


Blum: Now, Dan, I’ve seen the bird books. These birds are extremely colorful. Any tips on the
best chance of actually seeing them?


Best: Well, bring your binoculars into the forest with you. And don’t charge up to every song
that you hear. Just slow down, take it nice and easy. Look where you hear a song. Watch for that
little movement of leaves. Spot that movement. Raise your binoculars and you’ll eventually see
them. You’ll get to see these different kinds of birds.


Blum: That’s naturalist Dan Best. Some of us live in one story houses and some in high-rise
buildings. It’s a good idea when bird-watching to remember that birds also have their own
preferred level. For the Great Lakes Radio Consortium, I’m Jim Blum.

Interview: Red-Winged Blackbirds Heralds of Spring

Many people in the (Midwest/Great Lakes region) are told to watch for the Robin as a sign that
Spring has come. But that bird may not be the best indicator, even after this especially cold
winter. The Great Lakes Radio Consortium’s Jim Blum decided to venture out beyond his
backyard to find a better sign:


Blum: You might think of a robin or a bluebird as harbingers of spring but that may not be
correct. I’m Jim Blum with naturalist Dan Best, we’re at the edge of a marsh on a soggy
afternoon.


Best: Well Jim, it’s true that the greater numbers of bluebirds and robins arrive back in these
parts in March, but bluebirds and robins – they’re frequent enough in winter to ruin their
reputations as the heralds of spring.


Blum: Well, I’m thinking you have another bird in mind.


Best: Well, yeah, I was thinking of the blackbirds actually. The grackles and red-winged
blackbirds. They usually hit town in February.


Blum: I’ve always associated red-winged black birds with cattails. Aren’t they birds of the
wetlands?


Best: Well, yes. Marshes are their traditional habitat and remain their preferred habitat. They
weave a basket-like nest among the stems of the cattails, the rushes or other tall plants at the
waters edge. And while marshes are their favorite still, they’ve branched out.


Blum: You mean they’re starting to use other habitats?


Best: Why yes, as you know Jim, in a trend that unfortunately continues today marshes and other
shallow water wetlands – as they have been for decades – have been drained or filled for
agriculture and building.


Blum: Which would explain why so many of our rare and endangered plants and animals are
wetland species.


Best: Yes, indeed. However, as many forms of wetland wildlife have declined with the loss of
their habitat, red wing black birds, apparently more adaptable, have made a successful transition
into upland habitats, such as meadows and grassy interstate margins, hay fields, clover, alfalfa
fields.


Blum: Well there’s no wonder why there’s so many of them. I can recall those huge flocks that
we saw in the fall strung out across the sky almost like a plume of smoke.


(sound of huge flocks of birds)


Best: Yeah, and every night for several weeks they gather by the hundreds to roost in trees near
somebody’s house.


(red-wing blackbird song)


Blum: Well, red-wing blackbirds at almost any time of the year are pretty noisy birds. Their
song, if you can call it that, certainly doesn’t rival the cardinal or any other songbird for that
matter.


Best: No, you’re right about that, Jim. Can’t argue that point.


Blum: What does the bird look like? Can you describe it?


Best: Well, as the name implies they’re overall black. The males, they have a yellowish wing
bar and they also have a red shoulder patch or epaulet that they display while they are
establishing their territory or engaging in courtship.


Blum: What about the females?


Best: Well, they’re different looking. They actually look like big sparrows. That is, they’re
kind of a dark brown and very streaky.


Blum: Describe this display that the male is putting on.


Best: Well, they find a prominent perch and then from here they fan out their wings and tail
feathers and let out a real boisterous kon-kor-eeeee.


Blum: So this is to establish territory and they’ll keep doing this even before the females have
arrived?


(walking in grass)


Best: That’s right. They’re staking their claim but once the once the girls arrive well then this
display really kicks into high gear.


Blum: What’s the best way to see the antics of the red wing?


Best: Well, since these birds are pretty common, chances are you’re not going to have to go too
far from home. A little patch of cattails or reeds alongside the road. I mean, invariably they’ll be
perched on a wire or on a tree nearby will be a male red-wing displaying.


Blum: While other birds get more poetic respect, I have a sense you feel this bird is special.


Best: Well, yeah, as spring proceeds we’ll see more musical songsters come our way, but
doggone it, you know, when I hear that quirky song of the red-winged blackbird in late winter
when there is still snow on the ground, to me, that’s one of the first sure signs of spring.


Blum: That’s naturalist Dan Best. I’m Jim Blum for the Great Lakes Radio Consortium. Let’s
check out that cattail stand, do you think we’re going to get one?


Best: Oh, I’ll betcha there’ll be one there.

Whoopers Make Spring Migration

A test flock of whooping cranes is winging its way north from Florida to Wisconsin this month.
That makes wildlife officials who are trying to restore the flock very happy. The Great Lakes
Radio Consortium’s Chuck Quirmbach reports:


The Whooping Crane Eastern Partnership is setting up the only migrating flock of whoopers in
the Eastern U.S. Almost two dozen birds are taking part and wildlife officials hope to teach
flying skills to another 20 crane chicks this summer.


Beth Goodman is whooping crane coordinator at the Wisconsin Department of Natural
Resources. She says the numbers show the experiment is on track.


“It underscores we set a goal that seems reasonable, and our goal is establishing 25 breeder pairs
and 125 migrating birds in the eastern migratory flock by the year 2020.”


The whooper was at its greatest danger of extinction sixty years ago when there were only 15
birds counted in the wild. The new flock already has exceeded that number. Goodman says one
of the tougher tasks this year will be raising enough private money to keep the project going
strong.

A new study in the journal Nature reveals that some birds can count. Researchers have found that
they’re able to identify and tally their eggs in order to improve their reproductive success. The
Great Lakes Consortium’s Sarah Hulett explains:


Bruce Lyon is a biologist at the University of California Santa Cruz. He made the discovery while
doing research on the reproductive behavior of American Coots. Coots are dark gray, duck-like
waterbirds that live in the northern U-S and southern Canada. They’re parasitic birds. That means
they lay some of their eggs in other coots’ nests – tricking the host birds into incubating eggs that
aren’t theirs.


But Lyon found that some females are able to recognize the foreign eggs by counting and ignoring
the imposters. Lyon says taking care of other birds’ eggs means a slimmer chance of their own
chicks surviving.


“There’s not enough food to go around, and if you end up raising somebody else’s chick, it
probably means you’ve lost one of your own.”


Lyon says a female coot will protect her babies by identifying eggs that aren’t her own, and burying
them or pushing them to the edge of the nest.

Enviros Push to Ban Wood Preservatives

Some environmental groups and labor unions are pushing for an end to using certain wood
preservatives in treated lumber. They’ve jointly filed a lawsuit in federal court to push the
Environmental Protection Agency to stop the use of the preservatives because they contain toxic
chemicals. The Great Lakes Radio Consortium’s Lester Graham reports:


The EPA acknowledges that some of the wood preservatives such as penta and creosote contain
chemicals that can cause cancer. But, the agency has long maintained that it cannot just ban the
wood preservatives used to treat lumber, utility poles and railroad ties. That’s because it says
there are no viable alternatives. Jay Feldman is with the environmental group “Beyond
Pesticides” which is one of the organizations suing the EPA. Feldman says the EPA position used to be true,
but not anymore:


“The alternatives are on line; they’re ready to go. It’s unnecessary for us to continue to dump
over a billion pounds of these wood preservatives into the environment on an annual basis.”


Feldman argues that recycled rubber, steel and plastic materials are available at about the same
cost. And he adds many power, telephone and cable lines can be put underground rather than on
creosote-treated utility poles. The Treated Wood Council indicates that its products are safe, but the industry is
beginning to offer different preservatives without the cancer-causing chemicals because of the
concerns.

Transcript

Some bird enthusiast clubs around the Midwest – Great Lakes Region are calling on their
members to put out extra bird feeders this winter. But as the Great Lakes Radio Consortium’s
Jonathan Ahl reports, the move might not be necessary:


Some of the clubs say birds are still suffering the effects of the West Nile Virus and need extra
food this winter to make sure they are healthy in the Spring. But not all scientists agree with that
claim. Barbara Frase is a biology professor at Bradley University in Peoria, Illinois. She says
there are only a few circumstances where birds need the extra food humans provide:


“In the winter, if there is a really long cold spell, then the birds are probably helped. The extra
food will help see them through that cold snap. Otherwise, it probably doesn’t add to their
survival ability.”


Frase says studies show birds that frequent bird feeders still get eighty percent of their food from
the wild. She says it is still a nice thing to help birds, but says the West Nile Virus is really not a
reason to put out an extra feeder this winter.
