Recovery: Saving Loons from Lead Fishing Tackle

Loons face many hazards. Here's one we can easily address: lead fishing tackle.

A night silence settled over Big Island Pond in southern New Hampshire when we lost the whippoorwills. But about 20 years ago common loons (“common” only north of the contiguous states) showed up for the first time in even my grandparents’ memory.

The territorial song of the males — wild, discordant yodeling — starts at one end of our island and is answered at the other. Then contact calls — soft owl-like hoots and wails like the whistles of distant freight trains. By day tremolos as the heavy, black-and-white-checkered birds descend in swift flight, hitting the water and skidding sideways like ditching aircraft.

In May 2009 I watched a loon haul onto our beach. It couldn’t hold up its head. It quivered. Its ruby eyes grew dull. Three hours later it was dead. A neurotoxin had destroyed cells in its liver, kidneys, eyes and brain. That neurotoxin was lead. A lead sinker as small as a split shot will do that.

Loons face hazards we can’t do much about. The contiguous states are on the southern fringe of their range, and global warming may drive them north. Mercury mobilized by acid rain and from fossil fuels poisons them. Boat traffic and shoreline development destroys nests and discourages nesting. On the Great Lakes — especially Lake Erie where nesting has been eliminated — thousands of migrating loons die each year, victims of alien species unleashed by humans. It works like this: zebra and quagga mussels from eastern Europe concentrate naturally occurring botulism bacteria, among the planet’s most lethal toxins. Round gobies from the Black and Caspian Sea regions eat the mussels. Loons eat the gobies.

Lead fishing tackle, however, is a hazard we can do something about. Non-toxic metals including steel, bismuth, copper and tin are cheap and readily available. Tungsten is relatively expensive but weighs more than lead. Non-toxics hold up better than lead, don’t snag as easily, keep tackle boxes cleaner and are safe for humans. Now there are even ceramic and natural rock sinkers. I shudder to recall all the times I bit shut sinkers and picked lead flecks from my teeth.

Outside the Great Lakes lead tackle is the leading cause of adult-loon mortality. In New Hampshire, for example, 48 percent of dead adult birds turned in to the Loon Preservation Committee were poisoned by lead. The committee and its partners rope off nesting sites, erect buoys and warning signs, deploy nesting rafts, rescue injured and stranded loons, host seminars, and work with dam owners to maintain suitable water levels. But prior to this year’s strict lead-tackle ban six full seasons of nesting-raft management were negated by just 38 pieces of ingested lead.

The only states with lead-tackle regulations are New Hampshire, Maine, Massachusetts, Vermont, New York and Washington. Many others, including Minnesota which has slightly more than half of all lower-48 loons, rely only on education.

“We’ve been educating about this problem since the early 1980s,” declares Loon Preservation Committee director Harry Vogel, “and the only point at which we saw a measurable decrease in lead mortality was when the legislature restricted sale and use. Education by itself doesn’t work because lead tackle remains widely available.” New Hampshire’s ban, strengthened in 2016, outlaws use and sale of lead sinkers and jigs weighing an ounce or less.

A law that looked to be as good as New Hampshire’s went into effect this year in Maine. But after hearings the legislature inserted an exemption for painted jigs in the mistaken notion that paint somehow prevents pebble-filled gizzards from grinding up lead. “We were dumfounded,” says a leading wildlife veterinarian, Dr. Mark Pokras of Tufts Cummings School of Veterinary Medicine, “That’s a huge loophole.”

“Why not a national ban,” I asked Vogel?

“Unfortunately, lead is widely viewed as a loon problem,” he said. “It’s a wildlife problem; more than two dozen species are poisoned by lead tackle. Most states don’t have loons, so there’s no enthusiasm for tackling this on a national level.”

There was plenty of enthusiasm, however, for shouting down a 2010 petition by environmental groups for a national ban on lead tackle and ammo under the Toxic Substances Control Act. The Recreational Fishing Alliance (funded largely by the tackle industry) called the petition “anti-fishing, anti-fisherman, doomsday protectionism in the name of loons and loony extremists.”

In February 2016 the U.S. House passed the “Sportsmen’s Heritage and Recreational Enhancement Act” that would bar EPA and even the Departments of Interior and Agriculture from regulating lead ammo and tackle.

Lead regulation isn’t even happening on most National Park units. In March 2009 the Park Service announced that it would ban lead tackle and ammo by the end of 2010. But a trade group called the American Sportfishing Association (ASA) and the gun lobby caterwauled. So the service backed off, applying the ammo ban only to its employees and requiring contracted concessionaires to restock with non-toxic tackle once they’d sold off their lead.

“National Parks such as Yellowstone and Glacier have long banned lead in most fishing activities, but sadly, these restrictions are not yet widespread,” remarks the Park Service’s chief of biological resources, Elaine Leslie. “There’s plenty of peer-reviewed science and evidence indicating the hazardous impacts of lead to a healthy environment — both in terrestrial and aquatic systems.”

Virtually all fishing organizations and publications that object to non-toxics receive and recycle such ASA fiction as “alternatives materials to lead can cost anglers up to 20 times what current tackle costs.” (The EPA reports that a switch to non-toxic tackle costs the average angler an additional 31 cents per year.)

Six years ago nature photographers Daniel and Ginger Poleschook received death threats when they led a campaign to ban lead tackle in Washington State. ASA opposition derailed effective regulation. So lead is illegal only on Washington lakes where loons are known to nest. But loons ingest lead on the other lakes; and about as many are poisoned there as on nesting lakes.

This column, though, is about recovery. And incredibly, with all they face, loons are recovering in the lower 48. While state lead bans are few and sometimes less than adequate, they’ve helped. Buoys, ropes, warning signs and nesting rafts play a big part. New Hampshire, for instance, has gone from fewer than 100 loon pairs in 1976 to 296; Vermont from 17 pairs in 1984 to 117; Massachusetts from no loons in 1975 to 43 pairs.

The Maine-based Biodiversity Research Institute has been netting loon chicks from healthy populations and moving them to depleted habitat where they’re placed in floating, predator-proof hacking pens stocked with live shiners they catch on their own. Over the last three years the institute has moved 17 chicks from northern Minnesota to barren lakes in the southern part of the state. Lakes in southeast Massachusetts got seven birds from upstate New York in 2015, this year four from New York and five from Maine.

With all the restoration effort and the cheap, superior tackle alternatives it’s nonsensical for states or federal agencies to allow lead. “Non-toxic tackle is a no-brainer,” says Pokras. “I don’t understand this opposition from the sportfishing community.”

But when I checked in with the sportfishing community that ASA claims to speak for I encountered only support for non-toxics. Pradco, among the world’s largest tackle manufactures, proudly reported that it had “pretty much eliminated lead.” Pradco and the Bass Pro Shops sell lots of tungsten because, as they explained, it performs better than lead and anglers demand it. L.L.Bean, long noted for environmental responsibility, sells little lead but, apparently buying into the Maine legislature’s superstition that paint protects fish-eating birds, still carries painted lead jigs. In 2015 it discontinued lead sinkers two ounces or less even though the 2016 law permits sale of sinkers over an ounce. Orvis sounded offended that I’d even asked about lead, explaining that it hasn’t sold the poison in years.

Maybe the Park Service’s Elaine Leslie says it best: “The United States is far behind many countries on addressing the lead issue. It is nearly 2017, and it’s time that we, the entire conservation community — which includes hunters and anglers — step up and do the right thing … There are no excuses for our inactions.

    I don’t understand the ASA’s reactions to switching to non-toxic sinkers and jigs for fishing. Lead in paint has been recognized as a major source of poisoning in children. Let’s also try to remember that Flint, MI isn’t having a water crisis because of non-toxic metal; it’s having a problem because of lead water pipes. If this travesty was allowed to occur then I guess it’s easy to see why the ASA and fishermen don’t recognize lead as a problem. Apparently, they don’t know or care about the environmental issues and consequences of using lead. Hey, non-toxic ammo, fishing sinkers, and fishing jigs kill just as well as lead ones, so why not switch? The simple answer is that there is no good reason for not switching. I would have suggested that education is a good way to get this message across, but some people are stubborn and don’t like having somebody telling them what to do, even if it is the right thing to do for the wildlife, the environment, or for their own families.

    This is a tragic consequence of our government’s lack of action regarding environmental concerns. We ARE way behind most developed nations on these issues, and it’s shocking and devastating to our environment, wild life and our children.

    Time to put profit behind people and all living things and make significant changes in the years to come. Thank you for this important article, and check out our website at healestate.com and see what we’re doing to contribute to a safer, healthier and more sustainable world.

  3. Mark Donner says:

    Psychopaths who call themselves “hunters” or”sportsmen” are just death merchants, murderers and scum.

  4. elizabeth clemmey says:

    Is there any movement to illuminate these lead products. not just for the loons but for the the improvement and health of our waterways in general?

  5. Diane Stoecken says:

    Let’s restore instead of destroy. Ban lead-based fishing tackle.

  6. Sharon Moore says:

    The way corporate industries treat our natural habitats is downright unAmerican. True love of our country includes its magnificent lands and waters and their wildlife. I suspect that we, as a nation, are so out of touch with the natural world that too few of us care about it. We need a movement to reverse that trend! (And closer supervision of the BLM, as well.)

  7. James Kenny says:

    Great article, even if this Ted Williams “detests” baseball. Loons are probably my favorite aquatic bird and I always associate them with days and evenings spent around lakes in Maine when I was a kid. Of course, it makes sense to eliminate lead from fishing tackle and I’m just as baffled by the opposition to the use of tungsten or other substitutes. It just might be a reflexive reactionary take that opposes any “environmentalist” suggestions, as if showing environmental concerns were to threaten the rights of fishermen and hunters. But keep the opposition to the use of lead sinkers going: this, too, will change.

  8. John Korstad, PhD says:

    I appreciate this well-informed and needed post! 🙂

  9. Mary Baker Dittma says:

    Step up and do the right thing … this should be the slogan for 2017. America should be leading other countries, not behind intros issue. Lead is dangerous, lets do something about it ……….. Remove it!
    Save the Loons! It is our job to protect and save the planet and all the animals on it.

  10. C. T. says:

    Why can’t we just say lead is toxic to HUMANS [in the water and elsewhere] and let THAT be the end to lead use in hunting/fishing? Then wouldn’t ALL creatures be safer from lead?

  11. Daviod Hochtritt says:

    Loons on my lake- make the summers a thing of beauty.

  12. Alice Henneberg says:

    If I had only one wish it would be to enhance the compassion and understanding of humans toward the animals in the natural world.

  13. michele prokop says:

    My question is: what should one do with OLD lead weights? Throwing them in the garbage will not stop the lead from leaching from landfills. Sooooo….How does one dispose of lead weights safely?

  14. Barbara Harris says:

    These are very special animals,as all of life is. Please stop hurting them and their right to health and freedom from harm!
    There is no time to waste. Thank you kindly
