The pesticide DDT almost wiped
out the double-crested cormorant.
Now, the bird is thriving, and it’s
blamed for devouring fish in lakes,
rivers, and fish farms in many parts
of the country. Karen Kelly reports

with this unpopular bird:

(sound of clanking and birds)

Mike Smith eases a boat into the shallow water just off Little Murphy Island. It’s a tiny patch of sand and trees in the middle of the St. Lawrence River. It straddles the New York border with Canada.

Smith is a wildlife technician with New York’s department of environmental conservation. He specializes in cormorant management. That means he knocks down nests, breaks eggs, and – very occasionally – shoots them.

Before he even jumps off the boat, he starts counting the birds that are poking out of nests in the treetops.

“I see a few. I’m looking at their nests. We tried to have a zero percent successful reproduction rate.”

Smith counts maybe ten nests. They started with 150 or so in the spring.

There are tens of thousands of these birds. They spend their summers in the north. And in the winter, they go south where they raid fish farms.

Biologists estimate each bird eats a pound of fish a day. That can make a dent in the local fish population. The birds also strip trees of their leaves to create nests. And their guano ends up killing the trees’ root systems. That ends up driving out other animals that need vegetation.

Some people feel the birds should be eradicated. One group of anglers was even arrested for killing hundreds of them on Lake Ontario.

There are others, like the group Cormorant Defenders International. They feel they should be protected.

It’s up to biologists like Jim Farquhar of New York’s Department of Environmental Conservation to find the balance between human needs and cormorants.

Farquhar: “We have needs too, as people.”

Karen: “And we’re competing with them.”

Farquhar: “And we’re competing with them in some cases. Hopefully, if we can inject good science, we make good decisions as a result.”

The biologists’ biggest effort has been on Lake Ontario. They’ve been destroying nests there — and killing some adults – for ten years. Farquhar says they’re finally seeing results.

They’ve reduced the cormorant population on the lake by about two-thirds, and the fishing’s improved.

Now, the biologists are trying to have the same success on the St. Lawrence River. But they’ve only seen a 13% decrease in the number of cormorant nests and they’ve been doing it for four years.

Part of the challenge is that most of the birds live on Canadian soil where management is left to the landowner.

Local anglers like Steve Sharland of Ogdensburg, New York, are frustrated with the slow progress.

“They should eliminate them. They’re not a Northern New York bird and what they’re doing to our fisheries is a sin.”

That’s a common misconception. Actually, the cormorant is native to the region but few people have seen them in such large numbers.

Sharland says some people are so frustrated, they’ve been shooting the birds illegally. But Jim Farquhar believes those are isolated incidents.

“Mike just mentioned that we’ve got some black-crowned night herons nesting out here. It’s another species we’re concerned about, and one we’ve been trying to actively protect from the cormorants. So that’s a good sign.”

A good sign. But it’s another species trying to live on this small patch of land. And the biologists’ balancing act has become even more delicate.

A Battle Over the Treatment of Livestock

  • The treatment of laying hens is one part of the issue getting a lot of attention in Ohio. (Photo source: LEAPTOUY at Wikimedia Commons)

Recently, six states have changed their laws to require
better conditions for farm animals. But there’s a battle

Recently, six states have changed their laws to require
better conditions for farm animals. But there’s a battle
brewing in one state that’s putting a new spin on the debate.
Julie Grant reports:

The Humane Society of the United States says it’s shameful
the way animals are treated on many American farms. Paul
Shapiro says veal calves, pregnant pigs, and egg-laying
hens are all kept in cages so small – it’s cruel.

“Hundreds of millions of egg-laying hens in the nation are
confined in tiny battery cages that are so restrictive the birds
are unable even to spread their wings.”

Shapiro says some farms house millions of hens, all
squished into tiny cages, and none of them get the chance to
nest, or act in any way like natural chickens. The Humane
Society has spent millions of dollars pushing for change in
California and other states.

But when the Humane Society hit Ohio with its campaign,
the state Farm Bureau Federation pushed back.

Keith Stimpert is spokesman for the Ohio Farm Bureau. He
says there’s a reason cages are a certain size for hens,
calves, and pigs: the animals’ safety.

“You can expand space, but you’re going to increase
aspects of fighting or cannibalistic behavior, or the chance
for that sow to fall down while she’s pregnant.”

Stimpert says the Humane Society doesn’t understand
livestock.

So instead of negotiating with the Humane Society, the Ohio
Farm Bureau is proposing something new: a state board to
oversee the care of livestock.

“I think we, in this case, can get to a better resolution on
animal care by organizing this board.”

The board would include family farmers, veterinarians, a
food safety expert, and a member of a local chapter of the
Humane Society, among others.

Voters will probably be asked in November to decide
whether to change the state constitution to create this board.

But the Humane Society’s Paul Shapiro says the board will
be stacked by the Farm Bureau. He calls it a power grab by
big agriculture.

“Keep in mind that these are people who have opposed,
tooth and nail, any form of agricultural regulation for years,
and now, all of a sudden, in just a few weeks, they’ve gotten
religion and feel grave urgency to enshrine in the state’ s
constitution their own favored system of oversight.”

Shapiro says this board will only protect the status quo. And
that’s not good for the animals.

Egg producer Mark Whipple runs a small farm in Clinton,
Ohio. He’s got about 1,500 hens. We caught up with him
delivering eggs at a local health food store.

He says his hens are free range.

“There ain’t no cages, really. They go in the box, lay their
egg, and go out and run around with the rest of ‘em, go eat,
drink, I don’t know, just be free.”

Whipple says he was never inclined to cage the hens.

You might expect him to side with the Humane Society on
this debate. But he doesn’t trust them to make decisions for
farmers.

“I don’t know that they really know where their food comes
from – other than they go to the grocery store or they go to
the refrigerator. Unfortunately, that’s a lot the mentality of
the world right now, so far removed from the farm at all,
knowing about livestock.”

Whipple says there are good producers and bad producers
out there – just like any business. He would rather see a
board like the one proposed by the farm bureau than a
mandate on cage sizes from a Washington DC-based
lobbying group.

But the Humane Society says the board proposed by the
Farm Bureau won’t make things better. If it’s approved by
voters this November, the Society plans to place its own
initiative on animal treatment on the ballot next year.

Meanwhile, other farm states are considering the Ohio Farm
Bureau’s approach and might soon have their own advisory
boards on how to treat animals.

Building Penguin Beach Homes

  • The penguins' natural shelter (their own dung) is being removed from the landscape for fertilizer. So, conservationists are supplying penguins with artificial homes in which to nest. (Photo by Frank Olivier)

Along with lions and elephants, Southern Africa is home to a species of penguin. But the African penguin population is dwindling – and scientists are trying to turn things around for the bird. Ann Dornfeld reports:

Transcript

Along with lions and elephants, Southern Africa is home to a species of penguin. But the African penguin population is dwindling – and scientists are trying to turn things around for the bird. Ann Dornfeld reports:

Dyer Island sits just off the coast of the Western Cape of South Africa. It’s tiny, and pretty much consists of two things. Rocks. And birds.

Along with Cape cormorants, Hartlaub’s gulls and swift terns, Dyer Island is the nesting ground for hundreds of African penguins. Although they’re half the size of the Emperor penguins from that movie you might have seen, the species act a lot alike – waddling, awkwardly hopping, and squawking at each other over territory disputes. But today, these African penguins aren’t doing much of anything. That’s not them you hear. They’re mostly just standing still, trying to catch a breeze in the 90-degree heat.

“If you have a look here, you get an idea of just the heat stress of the birds. See this bird over here who’s just sort of standing, gasping, that’s an indication of heat stress.”

Lauren Waller monitors the penguin colony for Cape Nature. That’s the provincial conservation department. Waller says penguins used to find protection from the heat by burrowing into centuries’ worth of bird guano. That allowed them to keep cool, and lay their eggs out of predators’ reach. But in the 19th and 20th centuries, people dug out the guano between the rocks along the Southern Africa coast and sold it as fertilizer.

“And now what you’ve got if you have a look around the island is just – it’s rock, and the penguins can’t burrow into that. And so it now forces them to breed on the surface.”

When penguins make their nests out in the open, kelp gulls can snatch their eggs and chicks. And because penguins breed during African summers, the heat can be overwhelming. Parents often leave the nest just to cool off at sea, and their eggs or chicks die. It will take decades for the guano to build back up.

Scientists are trying to help the penguins out. They’re building nests for them. Waller says Dyer Island is the main testing ground.

“The nests are made out of fiberglass mold and they sort of mimic natural burrows that the bird would make in the ground. They’re kind of like a really small igloo shape, and big enough that you can fit two adult birds inside and their chicks as well.”

The nests are covered with rocks to prevent a greenhouse effect inside the igloos. Waller says they’re experimenting with different materials and nest arrays to see whether the penguins prefer their igloos in a cul-de-sac pattern, or a secluded ocean view. Some nests never catch on, but others have become prime real estate.

“Here you can see we have a colony of 15 nests, and already nine of them are occupied and it’s not their peak breeding yet. So this specific colony is looking really, really good.”

We peek inside one of the plastic igloos where a mother is guarding two fuzzy brown chicks.

“She’s turning her head from side to side.”

“Yeah, it’s a kind of aggressive, stay-away kind of behavior. But if you look behind her you can see the little heads sticking out!”

Waller says as successful as the artificial nests have been, commercial overfishing of sardines and anchovies also affects chick survival. At one well-protected nest a few yards away, she finds an abandoned egg and a dead chick. She says it may be that the parents couldn’t find enough fish.

“It is hard. Knowing their numbers are just going down every year. And you become quite desperate to do something so that these birds don’t have these breeding failures.”

The South African government has banned fishing around one island with penguin colonies to see whether it makes a difference in the birds’ survival rates. Waller says she’s hopeful that now is the turning point for African penguins.

Water Pollution Feminizing Fish

  • Chemicals in the water are mixing up fish's gender (Photo courtesy of US Fish and Wildlife Service)

Scientists already know estrogen from things like ‘The Pill’ is getting into the water and causing reproductive problems for fish. Male fish are picking up female attributes.

Scientists already know estrogen from things like ‘The Pill’ is getting into the water and causing reproductive problems for fish. Male fish are picking up female attributes. Some males are even growing eggs. Now a study finds there are other chemicals getting into water that might be messing with fish gender even more. Rebecca Williams reports:

This study’s found a group of chemicals that block the male hormone testosterone is getting into rivers.

Charles Tyler is the lead author of the paper in the journal Environmental Health Perspectives.

He says they don’t know exactly where these chemicals are coming from, but some medicines and pesticides can block testosterone. So, add that to the estrogen…

“And so it’s very likely they’re going to have interactive and additive effects, if you like, to induce a double whammy on the poor fish.”

Tyler says they don’t know if what’s happening in fish is also happening in people.

Human male fertility has been declining. But there might be other chemicals contributing to the problem.

And besides, there’s a difference. Fish can’t get away from these testosterone blocking chemicals or the estrogen in the water – they live and swim in them. So Tyler says they’re getting a much higher dose.

Osprey Nest Near Fish Hatchery

Ospreys are birds of prey that eat fish. Todd Melby tells us
about a pair of osprey that tried to nest near a fish hatchery:

The osprey is a raptor that scoops fish out of rivers and lakes.

So when a pair of osprey decided to mate near a DNR fish hatchery south of
Minneapolis, biologists were delighted and worried.

Ospreys rarely nest so far south. So that was good news. What worried biologists was
whether the birds would eat the fish. Biologists decided these fish were too small.

Another worry was the ospreys’ choice of a nesting site. In this case, the birds picked an
electrical power pole.

Lisa Gelvin-Innvaer is with the Minnesota DNR.

“They like high areas. Places that have room for them to put their nest. Transmission
poles often provide that.”

Biologists decided that was a bad idea, so they’ve built a tall nesting platform near the
power pole.

“We’re hopeful with the new nesting platform, that they’ll come back and attempt to nest
again.”

Bugs Getting Confused by Asphalt

Transcript

Bugs are getting confused by the
reflections from manmade structures.
Rebecca Williams reports on a new study:

If you’ve ever noticed swarms of insects hovering over your car, there’s a
good chance they’re mistaking it for water.


Smooth, dark surfaces like cars and asphalt reflect polarized light. That’s
what bugs see – and that tricks insects such as dragonflies.


Bruce Robertson is an author of the study in the journal Frontiers in Ecology
and the Environment.


“Asphalt actually reflects polarized light more strongly than water and so it
looks more like water than water! And so these organisms are thinking
they’re finding a place to breed and hunt and lay eggs and mate when in fact
they’re finding a place that’s very dangerous.”


Robertson says these bugs swarm over buildings and roads in huge numbers,
and can die of exhaustion.


But he says it might be possible to stop tricking the bugs. Things like
adding white curtains to dark windows or adding a little bit of gravel to
asphalt to make the surfaces reflect less polarized light.

Lead Poisoning and California Condors

It’s been decades, but there are now more California Condors in the wild than there
are in captivity. That’s thanks to two condor chicks who recently left their nests in
the Grand Canyon. As Sadie Babits reports, biologists are thrilled, but one of the
problems that caused the decline in condors still exists:


At the World Center for Birds of Prey in Boise, Idaho, there’s a wood fence that
protects the California Condors that live behind it.

“Just lately in order to minimize the exposure of our adult breeding pairs to humans,
we’ve built this security fence or actually it’s a visual barrier, we call it.”

That’s Bill Heinrich. He overseas the California Condor Recovery program at the
Center.

There is this one small break in the fence – a part that hasn’t been built yet. And
behind some chain link, I can see some very large birds…

Sadie: “Is that a Condor right there??”

Bill: “Yeah… you can see an adult condor standing, a pair of them on a perch.”

Sadie: “Ooohhhh!”

Bill: “You can kind of get an idea of just how big they really are.

Sadie: “They’re huge!”

Bill: “They weigh anywhere from 18-25 pounds and have close to a 10 foot wingspan.”

In the early 1980s the California Condors almost went the way of the Dodo –
extinct. Only 22 of these birds remained in the wild.

The big birds were killed by hunters. They died from lead poisoning after eating
animals killed with lead bullets. And their own genetic makeup didn’t help much
either.

These birds, shall we say, have a low sex drive. Rather than produce chicks every
year and gamble that they’ll survive, condors lay one egg every other year. That
hasn’t worked so well.

So biologists thought they’d help. They started capturing the endangered condors to
begin a captive breeding program. In 1987, the last wild bird was caught.

Bill Heinrich recalls there was plenty of controversy over that decision.

“People thought well you should let them go extinct with dignity or you can try to
breed them in captivity but you might fail and then you would have lost them in the
wild that much quicker.”

But the move saved the birds from being killed by hunters or from eventual lead
poisoning.

And, the breeding program, well, let’s just say the numbers speak for themselves.
Down to 22 birds in 1987, today there are now 327 California Condors. And more
than half of those birds are back in the wild.

Bill Heinrich says next spring some of these condors will be released some where
around the Grand Canyon in Arizona.

That’s where the birds will once again be exposed to one of the factors that lead to
their decline. It’s not hunters these days. The birds are protected by the Endangered
Species Act. But lead poisoning. Condors feed on gut piles and carcasses left by
hunters. If a hunter uses lead bullets, the bullet will explode sending tiny fragments
of lead through the meat. It’s enough to make a condor sick. Heinrich says lead
poisoning remains the single biggest threat to the birds.

“You know if hadn’t been for the lead issue coming up, I would have thought, I
didn’t have any reservations about it being successful until the lead problem cropped
up.”

Every year, biologists have to test the birds for lead poisoning. They’ve been working
with the Arizona Game and Fish Department to hand out free non-lead bullets to
hunters in the area. Last year, not a single condor died from lead poisoning. This
year, biologists have had to treat six birds, all of which are expected to make a full
recovery.

In California, the state has banned lead ammunition because of the lead poisoning
concern. But hunters don’t think lead bullets are a real problem, and they really
don’t want to pay for different kinds of bullets because that is a lot more expensive.

City Chickens and Urban Eggs

Maybe it’s easy to imagine chickens
cooing and clucking on American farms, but
how about in big-city backyards? Well,
keeping chickens is legal in the nation’s
three largest cities, but in one of them,
chicken-lovers nearly lost that right.
Shawn Allee tells how some urban
chicken-keepers were nearly caught off guard,
and how they plan to keep their chickens in
the coop:

No one’s sure how many chickens are in Chicago’s backyards. But honestly, few people
thought about it until last year.

That’s when one woman showed up at a city hearing.

“Hi. My name is Edie Cavanaugh, and I’ve lived in Chicago, since 1968.”

Cavanaugh told aldermen she’d caught messy, noisy chickens clucking around her
neighborhood.

She was stunned the city wouldn’t round them up.

“I was told chickens are permitted as pets in Chicago, and I said that’s impossible,
this is a city.”

Cavanaugh’s story ruffled plenty of feathers.

You see, even some aldermen didn’t know that keeping chickens as pets or for eggs in
Chicago is okay.

“I was riding down the street, and I seen a rooster. I was like, ‘What is this?’”

For a month, it seemed Chicago’s city council would ban chicken-keeping.

People who already had chickens worried their birds were destined for the stew pot.

But Chicago aldermen kept chicken-raising legal.

Chicago’s pro-chicken contingent saw the fight as a wake-up call. Some figured, if they
wanted to keep birds, they’d better police themselves.

“So, welcome everybody for coming to the first-ever Chicago backyard Chicken
workshop.”

Martha Boyd is starting seminars about urban chickens.

She’s part of the Angelic Organics Learning Center, a group that promotes urban
agriculture.

Boyd is confident city-people can raise more of their own food if they’re neighborly
about it.

“So the idea of the backyard chicken workshop is so we can have this thing grow
without creating more problems and potentially, then, having the backlash to the
backyard chickens.”

For this first seminar, Boyd invited chicken-raising veterans to a church basement.

One is Tom Rosenfeld.

His advice to urban chicken lovers? Talk to your neighbors. And, hey, if they cringe, get
creative.

“It also helps to bribe them, because if they think they’re going to get some eggs out
of the deal or they think they’re kids come over and pet them or whatever, then of
course they’ll be a little more understanding when one day you leave the door open
and there’re chickens running around the yard or other issues.”

Rosenfeld says those ‘other issues’ arise pretty quickly. In fact, just a few hours after
chickens eat.

“A lot about chicken keeping is about poop because they do it a lot. They do it in
surprisingly large quantities at a time.”

Rosenfeld says you can literally get ankle deep in the stuff if you’re not vigilant.

But bribery helps here, too. Rosenfeld says chicken poop makes excellent garden
compost.

“Our neighbors love it. They’ll come by with a bucket and that’s their way of
participating.”

Rosenfeld says the last issue that ticks off neighbors is noise.

There’s no such thing as a chicken muzzle, but there’s still a solution – and there’s no
bribe necessary.

You see, male chickens are the noisy bunch, so if you just want eggs…

“You don’t need a rooster. It’s a sad reality as a male chicken keeper to realize that
roosters aren’t necessary. They’re only necessary if you want chicks.”

Rosenfeld says urban chicken-raising could catch on where it’s legal – if people keep a lid
on noise and smells.

As for places where it’s not legal?

You might want to change the law at city hall – just don’t try to bribe your alderman with
fresh eggs.

A Treatment for Bleeding Fish Disease?

A common treatment in fish hatcheries may slow – or even stop –

the spread of an invasive virus that’s killing fish across the Great Lakes.

Jonathan Brown has more:

It’s called Viral Hemorrhagic Septicemia. Humans can’t catch it, but it
causes internal bleeding in fish.

The virus is hurting the region’s multi-billion-dollar sport fishing industry.

Now, researchers are finding that adding iodine – a common practice in fish
hatcheries – could prevent the virus from spreading.

Steve LePan is a biologist for the state of New York. He says a study at
Cornell University found Walleye eggs treated with an iodine solution were
not infected with VHS.

“We can’t say for sure that it’s exclusively the iodine that kills it. There may
be other things we do to the eggs that also affect the virus, as well.”

Those ‘other’ treatments include bathing Walleye eggs in Tannic Acid for a
few minutes before incubation.

LePan says there’s still a lot to learn about VHS, but he’s cautiously
optimistic that hatcheries can breed fish uninfected by the disease.

Nature’s Little Architects

Some of the world’s most intricate
architecture is not always constructed by
humans. Sometimes the most skilled architectural
wonders are designed by nature. Gretchen Cuda reports on an exhibit that celebrates
birds’ nests:

Judith McMillan didn’t find her inspiration in tree branches. She found it in the
basement of the museum where she works. She was rummaging through drawers
there when she came across a hundred-year-old collection of bird nests.

“This Museum must have 10 cabinets full of bird’s nests.”

She was fascinated and immediately knew she had a new subject for her art.

McMillan is a photographer who has been volunteering at the Cleveland Museum of
Natural history for 20 years. In her latest exhibit, titled “Nesting”, she captures some
of natures most inspiring, and often overlooked architecture – the nests of birds.

(sound of exhibit crowd)

“I was looking for nests that were different from each other so that you could see that
these birds were little architects. And there were so many different kinds of materials
used – and then the eggs could be so different. Some with little tiny speckles, some
with different colors some with little calligraphic streaks around them, so it was that
variety that I wanted to capture.”

All the photographs are in black and white – because she really wanted people to
concentrate on the architecture without being seduced by the color. She’s fascinated
by the way different birds chose very specific materials to work with – everything
from marsh reeds, grape vine, or little knotty twigs – like this one.

“This is a vermillion flycatcher – it’s almost like it’s made of pick up sticks in the way
their pushed together.”

And to emphasize the diversity of structures birds can create she shows me an
Orioles nest that’s five inches deep and formerly hung like a basket from a tree.

“I actually had to shine a flashlight down in it when I was taking the photograph in
order to get the eggs to show up.”

Most of the nests and eggs were collected around the turn of the 20th century by
amateur naturalists who never thought twice about disturbing the natural wildlife.

But the practice eventually fell out of fashion as people became more
environmentally conscious and large nest and egg collections were often turned over
to museums – explains Andy Jones the museum’s ornithologist.

“People whose grandfathers were dealing with eggs as a hobby, well their
grandfathers are passing away and so they contact their local university or natural
history museum, and say, ‘hey do you want these?’”

Those specimens were originally collected just because they were pretty. These
days, they’re still beautiful, but they also serve a scientific purpose. Scientists can
look at things such as the thickness of the shells, or the type and number of birds
found in a specific location and tell a lot about the birds. They can see where birds
used to live and how far their territories reached. They can even tell if a bird that’s
extinct now once lived in an area.

Judith McMillan hopes her photographs will not only show how beautiful the birds’
handiwork was, but will also inspire people to do something about saving the birds
that are still here.

“I didn’t understand until I started using a camera myself how you can isolate
something and make people look at it differently–And I hope through my
photographs I’m getting people to take a fresh look at things. It’s hard to have an
appreciation of nature unless you really look at it and start to really care about it.”

Recent surveys have found that many songbirds are disappearing. If people don’t
start caring, those photographs and drawers full of nests might become the only
reminders of many more species that go extinct.
