There are few things as aggravating as getting stuck in a traffic jam. But for some drivers crossing a busy bridge from the U.S. to Canada there’s aggravation on top of aggravation. Joyce Kryszak reports that’s because a plan to build an additional bridge is being blocked by concern for a bird and a little fish that it eats.

Every year, millions of people cross the mighty Niagara River on the Peace Bridge that connects Buffalo, New York to Canada. And many of them sit for hours in a traffic jam. The border crossing and passport checks slow things down. But there are just not enough lanes for all the traffic.

Ice delivery man Tim Holliday is one of those who is fed up with hours and hours of bridge delays.

“Like, I gotta go to the duty-free here, and when I’m coming out of here I have to go through customs and they always ask, what were you doing in Canada?” said Holliday. “I’m just sick of the hassles, you know?”

Transportation officials say a new bridge is needed. The traffic problems will only get worse. Because of increased trade, about eleven million additional travelers are expected to be using the Peace Bridge over the next decade.

And that’s a headache for Ron Rienas. He manages the busy international bridge crossing. He says building a new bridge would help with the traffic delays and help with national security.

“This is a border improvement project designed to address redundancy issues, security issues, traffic flow, all of those things, maintenance issues…all of those are impacted by not being able to proceed with the project,” said Rienas.

A second bridge has been designed. It’s a cable-stayed bridge with towers as high as the Washington monument.

Brian Higgins is Congressman for the area. He’s pushing for federal approval of the impressive cable design. He says the region needs an iconic symbol of progress.

“We are in the eleventh hour of a project that’s been going on for fifteen years. We need additional capacity at the Peace Bridge to promote the efficient, predictable flow of commerce between the United States and Canada – we need an iconic bridge, a signature bridge,” said Higgins.

But that signature bridge is exactly the kind of design that is dangerous to many birds.

And the Niagara River is a virtual highway for nearly three hundred kinds of birds. The cables can be invisible to the birds and they can fly into them and die.

Among those birds is the Common Tern. It’s an endgangered species.

Terry Yonker knows these and other birds better than most.

“We probably documented somewhere in the range of half a million birds, and there’s a common tern right there.”

Yonker is a scientist and a former Ornithological Society president. He wrote an environmental study that recommended against the bridge’s cable design because it could kill hundreds of different kinds of birds, including the endangered tern.

Yonker says even if it avoided hitting the cables by flying over the bridge, the tern would be stressed by such a tall bridge design. That’s because it has to make eight trips over the bridge each day to feed its young. But he says it probably wouldn’t make that many trips if the new bridge is any higher than the Peace Bridge.

“You raise that structure and they’ll have to spend a lot of energy doing that. They’ll maybe make five or six trips a day and that means one or two chicks are going to get less food out there,” said Yonker.

The other concern is a food source for the tern.

Fishery experts say the enormous piers would change water currents, eventually killing off the Emerald Shiner. That’s the tiny fish the endangered bird feeds on.

So a new design is being recommended: A lower bridge with smaller piers to protect the tern and the emerald shiner.

Federal and state agencies are working to find a way to mitigate the threat to the birds and fish by altering the plans for the new bridge. But environmental experts say you can’t mitigate extinction.

Environmentalists and some biologists say the common tern is more than an endangered bird. They say it’s a warning, about what happens when sound science is ignored for the sake of progress.

But, try explaining that to the people stuck in traffic for hours because a second bridge is being blocked to save a small bird and a little fish.

Across the Great Lakes region the recovery of the cormorant is booming. But some anglers and resort owners think the cormorants are eating too many of the fish that people like to eat. In some areas, wildlife managers have resorted to killing cormorants on popular fishing lakes. In one case, critics say there’s not enough evidence to justify the killing. The Great Lakes Radio Consortium’s Stephanie Hemphill reports:


Larry Jacobson is the third generation in his family to run the Hiawatha Beach Resort on Leech Lake, about two hundred miles north of Minneapolis. Three years ago, on fishing opener weekend, all of his twenty-one cabins were full. This year, he had no guests. Jacobson says the word has spread that fishing is down on Leech Lake. He blames the cormorants. The birds nest on a small island in the south end of the lake. Eight years ago, there were fifty nests; last year, there were two thousand five hundred.


“The cormorants eat about a pound fish a day. The way the population was just exploding out there, you could see writing was on the wall, that this was really going to make dramatic impact.”


Jacobson says his guests are still catching big walleye, but the smaller, pan-sized walleye are getting hard to find.


There are several reasons why the walleye population might be down, but Jacobson and other business owners blame it on the cormorants, and they’ve asked the Department of Natural Resources to do something about the birds.


“Leech needs to be maintained as high quality fishery. There’s such an economic impact to the area from walleyes, that if you don’t maintain it that way, everyone’s going to be suffering.”

Resource officials are responding to the resort owners’ concerns. The Leech Lake Band of Ojibwe owns the island. John Ringle is wildlife manager for the tribe.


“Okay we’re headed right at Little Pelican Island right now.”


Little Pelican Island is about three acres of sand and scruffy shrubs. Hundreds of cormorants cover the shore. Ringle says they fish out here in the open waters of Leech Lake.


“They’re omnivorous so they’re eating all sorts of different varieties of fish. Right now they’re probably eating large numbers of perch.”


Ringle is working with state and federal agencies to reduce the number of cormorants nesting here, eating fish, and crowding out other birds, such as the endangered common tern.


Normally, cormorants are a federally protected bird, just like eagles. That’s because they were almost wiped out by the insecticide DDT before it was banned in 1973. But a new rule allows resource officials to harass and even kill cormorants where they’re damaging other wildlife.


This summer, workers are sitting in hunting blinds on Little Pelican Island, shooting cormorants. They use air rifles to make as little noise as possible, so the other cormorants aren’t spooked away.


So far, they’ve killed more than two thousand birds. They plan to leave about five hundred nesting pairs alive. Ringle says nobody’s happy about shooting cormorants, but he says he thinks it’s necessary.


RINGLE: “My philosophy is that as mankind utilizes the resource, we have to manage them, we’re not in finite supply.”


HEMPHILL: “Do you think we know enough to manage them?”


RINGLE: “Not really. I think the public is demanding action prior to any conclusive study being conducted.”


And that’s a big problem for Francie Cuthbert. She’s a professor and cormorant researcher at the University of Minnesota. Cuthbert says the agencies that want to cut down the cormorant population skipped an important part of the management process: finding out what’s actually happening on Leech Lake.


“They’re really being driven by complaints from citizens and resort owners who are concerned about local economics, and who just don’t like the birds; they’re afraid of the numbers. If we responded to all natural resources conflicts this way, we’d be in a state of chaos.”


Cuthbert says even with the cormorants’ dramatic comeback since the days of DDT, there still aren’t as many as there were a hundred years ago. She says rather than kill cormorants, wildlife officials should try to boost the number of fish.


The state of Minnesota is working on that. It’s stocking Leech Lake with walleye for the first time this year. Conservation officials are studying some of the birds they killed to find out what they’re eating. And the state is also limiting what size of walleye anglers can catch so the fish can recover.


That makes resort owners like Larry Jacobson nervous, because he says a lot of anglers don’t like the limits. But at least he’s glad someone’s doing something.


“The fishery is a business, there’s no question about that. If you want to sustain our economy in this area, you’ve got to manage the lake.”


Workers will continue shooting cormorants occasionally through the summer. And the control effort could continue. Experts say it’ll take several years for the fish to recover enough to draw anglers back to the lake.
