The only controversy is the effect on the population, it isn’t really a controversy more of different studies show different things. The death rate varies from 1.9% to 44% from lead in studies. Most studies are somewhere in between those numbers. The argument is you have the anti-lead crowd touting the 44% study and the pro-lead group touting the 1.9%. As in all things it would be reasonable to assume they are both wrong and the truth is somewhere in the middle. So you have to ask your self how many deaths are too much 5%, 10%, 40%? To take action. My personal threshold is pretty low. why not do something if even a small amount is affected? Although I don’t subscribe to the same level of conspiracy as MT fudging research does exist. I don’t believe it is widespread though. The problem is when lay people only quote the numbers or research that proves their point and ignore the rest. Both sides do it...it was done by both in this whole thread. The problem with that is it creates a mistrust of research or a mistrust in the argument. T |

For the record I also think climate change is real but not caused by man. The fluctuations in temperature have been going on since the earth was formed, billions of years before mankind existed on the earth. Now, does our burning and tilling affect it? Well of course it doesn't help but our affect on the earth is probably more localized and maybe giving ourselves credit (or condemnation) for all the extra CO2 in the atmosphere (if the amount is actually abnormal) is thinking too mighty of ourselves. I used the word conspiracy to describe how I see people react to any debate with automatic blame to anyone who is trying to collect data and form an opinion. Much money has been wasted on these studies but much has also been spent well. My late friend who was a professional archaeologist told me many stories about the things he was accused of doing or not getting done. It sounds very difficult to make everyone happy when working in the scientific community, especially when the money to do the work comes from the taxpayers. |

In my loon nesting situation, last winter some eagles built a nest about a hundred yards from my loon nesting raft and the loons didn't come back this summer. On the lake I live on their are three eagles nests (all new last winter I think) and in my surveys this year found no loon chicks that make it to adulthood. Just like wolves vs. moose, we have eagles vs. loons. |

quote DeterminedOrange: "Speaking of eagles. They did a great job making a comeback over the last 30 years, too good in fact. Since eagles really are the only threat besides man to larger loons, they do have an effect on the population. A individual on a local lake in my area witnessed a loon kill a baby duck,than a short time later a eagle killed a baby loon. Probably what is much harder on Loons is egg eaters like sea gulls,otters etc. Snapping turtles are tough on little ones. It is a tough world out there. Yes habitat and disturbance by humans lead the decline. I think loons came back significantly with the end of DDT and dieldrin(sp) also. |

Conspiracy? The word has a negative connotation but when hundreds of millions of dollars, for example, is spent on grants to "study" global warming the results are rather predictable are they not particularly when little or no resources are allocated to study the opposing possibility i.e. that climate change may be a natural phenomena and to be expected wether man is present on the planet or absent entirely. And of course one can glean the pages of history where science has gotten it 180 degrees wrong. If there is a conspiracy it lies not in people doubting the veracity of scientific claims but rather within the realm of science itself. There is a precious few power brokers who decide who is worthy to have papers published and who is worthy to receive grants. This scenario tempers open and objective scientific research as to run contrary to the agenda (political correctness) is to put ones future success in doubt. And in fact it may lead to the destruction of ones career if objections are raised strenuously enough. As someone who aspired to be a scientist (my folks thought I had a "problem" as I spent all my time peering into a microscope) this pains me as I believe that truth, reality and clarity of thought should lead the way. But when science is pressured to arrive at preconceived results due to political agendas you cannot blame folk for being skeptical and that rightly so. |

Pinetree |
Sometimes as we see on this forum,some individuals will call people dishonest to get to their own desired outcome. You can question any study(and should) and examine it and that is what a good scientist does. Look at the varialbles involved. Many states and the Federal Government have done their own studies including Minnesota DNR staff on this issue. |

The premise I have that science has been (and frankly has always been) corrupted by politics only takes some thoughtful analysis and some historical digging. For example when it was first presented that the earth might be round and not the center of the universe heresy was the charge leveled and if I am not mistaken that famous notable figure was put to death. There is a lot of water under the bridge and space and time does not allow further fleshing out on the subject but you understand my point. Heretofore I had always placed considerable weight with the scientific community as per their objectivity and ascribed to them the highest of motives. But they are only people after all and as I have been on the planet these 56 years I have come to understand that human nature is easily influenced regardless its aspirations towards nobility. Am I throwing the entire scientific community under the bus? Well yes and no. I admire the intellect and pursuit of knowledge.........on the other hand I despise the pressures which are brought to bear from outside of science to insure an arrival at a predetermined conclusion i.e. political correctness. Climate change is a perfect example of what I am talking about. There are BILLIONS of dollars promoting climate change from disparate and varied groups. The globalists want to see a redistribution of wealth (The Paris Climate accord was much about reparations from wealthy countries, particularly the U.S. to 3rd world countries) while here on the domestic front you have the Utopian Statists (Progressives) who see carbon credits as the method to control industry. Carbon credits BTW will hurt the very people the Progressives claim to care about (poor) as corporate costs will be passed down to the consumer but I digress.......Plus it will be fraught with crony capitalism as carbon credits could be "bought" for a price of course. Why we would want politicians, who generally have never run anything, in charge of corporations is terrifying and a certain "Road to Serfdom" (Fredrick Hayek) but I am getting off track. This concept of a rather smallish group of power brokers deciding (of course!) who gets grant money and whose work gets published in the scientific community was first introduced to me via Jim Tour. Mr Tour is widely considered one of the foremost chemists in the world and thus beyond the reach of punitive measures. It was revelatory when he stated that to go against the politically established narratives is to put ones career in jeopardy. Check him out, I find his personal statements quite fascinating and fair minded. So, far from attributing conspiracies to science being corrupted via political correctness I use logic and sound premise to arrive at conclusions. I believe it is in the Evolution / creation link where he briefly discusses punitive measures taken against others who don't follow the accepted and expected narratives. Jim Tour |

Here in Florida we are not supposed to eat large Kingfish for example because as a predator of smaller fish they keep ingesting small amounts of lead over a long period of time which accumulates in their fatty tissues. Loons winter in Mexico if I am not mistaken. Could they be eating large amounts of baitfish which have lead in them?? Maybe the source of the lead isn't fishing tackle at all? Just a thought........I like to keep an open and intellectually curious mind. What say you? |

Maybe I am remembering "Gulf of Mexico" as to the wintering grounds? In any event I believe it is possible it is possible to have a thriving free market economy which enables liberty and allows the citizenry "the pursuit of happiness" while still being responsible stewards of the environment. Clarity, however is key. And to achieve clarity knowledge must not be obscured. The problem we have IMO is there is so much disinformation and outright lying that folks don't know what to believe anymore. Whats true and whats not is very difficult to distinguish when duplicity becomes a means to an end. We see it in politics and we see it in environmental extremism as well. Most people want to do the right thing. If it can honestly be shown that lead sinkers and lead jigs are harming healthy populations of such a magnificent bird I would like to think most folks would be on board with a lead ban. Heres another question.........do the birds pass the sinkers? I swallowed a lead split shot once (idiot!) while ice fishing. I sort of freaked out and got myself to the hospital where they told me it would most likely pass. How does the lead remain in the birds? |

I would be curious to have the research from the pro lead side brought forth as well and let a debate ensue. If lead is having a major impact I am somewhat surprised that the law has not already been changed. It seems like it would take more more than just lobbying efforts that would prevent it........there were lobbying efforts to allow lead in house paint, auto fuel and waterfowl ammo but those failed. So I am not buying that evil greedy corporations are whats preventing a ban. Certainly they have a vested interest in business as usual but they are not "all powerful". So perhaps the research is inconclusive or lead deaths are shown to be so marginal as to be insignificant. Still it does get ones attention, or at least it should. |
||
DeterminedOrange |
Some don't believe data brought forth by researchers simply because everything is a conspiracy or they don't like the results. Some would say they have been seeing the same number of loons for 60 years in lakes where they fish with lead tackle. A valid observation but a very narrow scope. Lead tackle does kill loons, hard to debate that. Simple solution is to eliminate it but complex in that it has to be done in ways that don't make it impossible to have successful fishing. I'd say there should be a deadline set and allow the market to drive how it is accomplished in that time frame. |

From us old old Timers I remember when the push was to get lead taken out of our gas(was that like mid 70's?),anyhow it was a huge political issue and some said lead wasn't doing any harm to the environment and vechiles engines would seize and blow up in short order. Well lead was taken out engines,result was engines lasting longer and much cleaner. I also remember changing spark plugs like every 6000 miles with lead fouling them. Now 60,000 to 100,000 miles on a set of spark plugs happens quite frequently. We can change if needed and sometimes to the better. |

" Lead is typically not soluble in water, however, the water in the BWCA is very soft and is slightly acidic (pH of approximately 5.5 depending on the lake). The article you mention says "Lead compounds are generally soluble in soft, slightly acidic water." So the is a chance that over time if the concentration of tackle is high enough that some lead could be present in the water. Likely not enough to affect us or the loons (unless they eat the tackle , as was previously mentioned). So while I don't know how much of a concern the contamination of lead tackle in the BWCA is currently, I believe that it is our responsibility to do everything we can to use the knowledge available to us to prevent it from becoming something that could have an impact on the ecosystem. They are around 5x more expensive per jig head, but to me its an investment worth making. Too each their own though... Plus: https://www.youtube.com/watch?v=2Adazf1kc64 :) |

inspector13 |
Yes, it says lead compounds are generally soluble in that type of water, compounds being the key word. Lead shot and sinkers are made of elemental lead, and very little else. Lead poisoning in the environment is due to wildlife ingesting the shot and sinkers, not because the water is contaminated with a high concentration of dissolved lead. If so we would be seeing advisories galore since fish would also be poisoned, and poisonous too. I assume the loons eat those things since they are the right size to help aid in digestion in their gizzard. So yes, do what you wish with regards to lead alternatives, but don’t fear the concentration of lead in the water. |

Sustainability? What does that mean? I gave always been suspicious of the term as it is the pet vernacular of the extreme environmental movement. Pinetree makes an excellent point about leaded gas. However, I will point out that in the end the robust debate concluded that unleaded gas would be superior for the very reasons you have pointed out and it was implemented in spite of the forces arrayed against. And that is why I like debate which is not politically correct but strives to achieve clarity and truth. Is lead a threat to healthy loon populations? Is it a threat to watersheds? Or is it much ado about nothing? I honestly can admit that I don't know. |

As far as lead split shot and jig heads, it will likely take a law to get rid of that too. Hopefully technology and new materials will be in place to make the transition smoother and be more accepted. It doesn't seem like there could be much concentration of tackle on the bottom and most places there isn't. However, some areas do get quite a buildup, I have a road next to the lake I live on and in the spring I can take a canoe over every night and pull 6 -10 lines with bobbers, weights and jig heads attached to stumps and logs in the water. One day this spring I got 25! Of course this only lasts until the crappies are done spawning but the tackle left behind is substantial and builds up over the years. As far as the differences in the mortality studies, I wonder if it is related to the concentration of the birds? In New England they are in larger groups feeding in the ocean and it may be more likely to find the bodies, especially with the abundance of large beaches. In MN the loons are scattered in often remote lakes, usually with a thousand acres or so of water per pair. Just a thought. |

A few thoughts......Did you consider the Jim Tour link? Here you have what is largely considered one of the top chemists in his field telling his students at a major university to not voice their doubts about controversial subjects such as evolution if they value their careers. This punishment of those who question such topics as Global Climate change (changed from Global Warming because the earth isn't following computer projections) is well documented. The intolerance is stunning. When you suggest the entire world believes something which the "right" (you single out evangelical christians) shows the intolerance and political correctness of which I speak. I am assuming you speak of "Climate Change"? Do you understand that "the entire world" does not subscribe to climate change as a goal of saving the planet but rather a way to redistribute wealth, more specifically the United States wealth. Of course "the rest of the world" wants the U.S. to sign on to the Paris Climate Accord which would transfer tens of billions of American dollars to other countries on the premise that we are at fault. Do you now understand the nexus between politics and science? There are plenty of scientists who do not subscribe to man caused climate change. But how would you know their opinions? There are tens of billions of dollars in play to establish the narrative. Those who question the veracity of the science are punished or destroyed. The goal is what has been the motivation of man since the beginning.........power and control. Convince the populace of their imminent demise and only through prompt and noble action can the calamity be prevented. Paint those who hold their hand up and say "um, exscuse me" as "bad people" who are ignorant (flat earthers). FWIW.......being a person of faith and a person of science is not mutually exclusive. Just ask Mr Tour or the vast myriad of Scientists and inventors throughout history which have relied on the "Spirit of Reality" (Holy Spirit) to guide them with their work. |

hawnjigs@yahoo.com Keith is a great person and has everything I need. In the 70's the larger population of loons across the BWCA was obvious to me. It was a big deal to see an eagle. Now we see eagles every day on every lake. Possums and coyotes are moving north. Many things have changed. I read that some loon wintering grounds have changed. |

quote mastertangler: " Loons winter in Mexico if I am not mistaken. " The Common Loon winters in the coastal waters of the US. From tracking devices attached to MN/WI loons they tend to migrate to the Atlantic or Gulf coast. Below is link to neat tracking site (they make this migration in a couple days). I haven't look at this in a while, I see most of the birds from this study have perished. USGS loon migration There has been other mortality issues from botulism due to Lake Michigan water quality. One of the more concerning events from some reports is loons not completing their migration and spending the winter or summer in other areas like Tennessee. This could just be some previously undocumented behavior but could be due to disturbances in habitat or health issues. Just a note for those who don't know, one of the most interesting loon features is their ability to eat freshwater fish half the year and salt water fish the other half. They can do this because of a special gland to remove and excrete the salt out near their eye. Amazing birds. |

Back to Loons and lead.........Hey at least I got something right ;-) Has anyone ever had a Loon hit their lure? I did some 20 years ago again at Isle Royale. I was throwing a small curly tail on a jig head and got a strike. I set the hook and the hook bent out straight. While i was eyeballing the bent hook a loon popped up right where I got the strike. Pretty sure it was the loon since I hadn't had a bite all day. Never had it happen again that I know of. |

Back to lead, as mutz said I think the biggest issues are cost and availability. It is getting easier but still if you want to go lead free you really have to search for quality replacements. It is slowly happening on it’s own as some of the tackle alternatives are more dense than lead allowing you to make heavier smaller lures. In many cases this allows a superior presentation. But still the cost is higher so the average angler will not switch in their own. I am of the opinion that even a small amount of loons dying is worth taking action but do need to point out that the New England study referenced in the OP is widely considered an outlier in the research and not the standard results. I did not do an exhaustive search but Minnesota and other states studies show the loon lead poisoning rate from tackle to account from 1.9% to 6.5% of all loon deaths while the New England study showed lead poisoning from fishing tackle at 44%. To my knowledge the New England study has never been reproduced (If I am wrong please point it out—this is interesting to me). To any one with a research background that means this is not reliable. It may be true, but there is also a good chance it is not...I will also point out that the original OP further skewed the results or report, probably unintentionally but none the less it is an example of using research and combining numbers to further prove a point by reporting the loon death rate was 49%— some of the lead poisoning were non-tackle reasons. If you read the original research they clearly make the distinction. If the show the OP listened to did not make this distinction then I’d question their motives and be careful believing what they say. I know I am contradicting my own stance, but it bothers me to when all the research is not presented...I personally think there is enough to take action without exaggerating results and creating mistrust. After all that I still think we need to move towards lead free I know I am personally looking for alternatives to my current gear. Over time I am concerned the numbers will go up and more lead is being deposited each year or what if the NE study isn’t an outlier. I want to do my part before that. T |

Not dismissive mastertangler, just letting you know how much the figures vary.

indeed price is a major obstacle. But in the last 10 years tackle manufactures have been using other metals to achieve a better product and fisherman have generally embraced using top of the line hooks and metals along with the higher price. As per trusting wildlife biologists........frankly, and it pains me to say this, i don't. I grew up wanting to be one. But I have seen political correctness and anti hunting / anti fishing as well as extreme environmentalism corrupt not only government but also science and that includes biologists. They have arrived at some "scientific conclusions" which are preposterous here is Florida and run contrary to truth and common sense. It used to be that outdoorsman, hunters and fisherman, wanted to be wildlife biologists. Not as much anymore but rather the opposite.........folk opposed to hunting and fishing and on board with the extreme environment movement. Thats what the Universities are churning out these days. |

If science was allowed to be separated from politics it would be great, but in this day and age, everyone tweaks "scientific evidence" to fit their agenda.

At Isle Royale this past summer I got to talk with three graduates out of what ever University is in Madison. One was working on her masters in Wildlife Biology, one had a degree in economics and one had a masters degree in a field I have forgotten. All 3 fully embraced Progressive causes without question. They showed no intellectual curiosity to the many points I brought up and were quite frankly completely unaware of anything but what was the mantra of the left. We spoke at length for at least an hour. The wildlife biologist used recent pollen samples to promote her belief of global warming. In her eyes that was proof positive because it sounded very scientific (couldn't be attributed to say perhaps an increase in agriculture but I digress). She was completely unaware of scientists falsifying data (Climategate), that the computer projections are so off as to make a language change from "global warming" to "climate change", that the oft quoted "99% of scientist agree" is a hoax (100 scientist polled if they earth was in a warming trend and left off if it was man caused) and that the famed Hockey stick graph is bad math. She was unaware of anything which ran contrary to the narrative. It bothered me that she was not intellectually curious and in fact intolerant of any perspective which didn't go along with what she embraced. Is that proof as to what is coming out of our Universities. No not really, but it is not so far off base as to make one wretch either. |

I would give 5 years notice to allow industry time to adapt. The upheaval would not be so drastic and I suspect that the loons effected is not a great percentage. But responsible stewards we should be and as Kerry has pointed out other materials are available howbeit they are somewhat more expensive. Are waterfowl hunters still using lead shot? Now that might be very expensive to shoot non-lead. Every shot you took would be like dollar bills flying through the air...... |

More recently (5-10 yrs??) they said that 25-50% of dead Loons had lead in their system, which is quite a variation. So using their figures, isn't it possible that the Loons with lead in their body died of the same cause as those that did not?? Another interesting situation is the ingesting of lead shot killing Ducks, Geese, and Loons theory. I don't know how many of you have driven through the city of Virginia, about 50 miles from Ely. If you do, drive by Mesabi Community College and notice the pond across from it, which is loaded with lead shot due to a trap club being located on the other side. Be very careful, as you will have to drive through many HUGE ducks and geese that wander freely between the lawn of the college and cross the road to the pond. With all the lead in that pond, there should be nothing but duck and goose bodies all over the place, but never heard any reports of that. |

KerryG is absolutely correct in that lead poisoning is a major cause of adult loon mortality. In chick through adolescent years there is predator losses to eagles, muskies, snapping turtles etc. and during nesting eggs can be lost to raccoons, skunks, gulls etc.. The exact percentage of deaths can be argued but I tend to believe wildlife biologists are publishing correct numbers from the data they are paid to collect. Lead shot for waterfowl hunting was eliminated many years ago and has probably helped. However, much of this hunting happens in ponds, swamps and small back bays, places loons don't frequent often. Loons typically hunt for fish in deeper water as diving is their specialty. Lead shot is a problem. Loons have a gizzard and need small pebbles to digest food, they get these from the lake bottoms and just scoop them up not telling the difference between stones and the lead. These bits of lead remain in the gizzard for a long period of time and gives the perfect chance to get in the blood stream and kill them. Geese and ducks are much more prolific in reproduction and losses to lead poisoning do not affect the population as greatly or at least allow them to rebound faster. Loons can easily ingest a 12" fish and are designed to handle spiny structures, taking down a jig head is no problem for that digestive system. Their gizzards use acids to help dissolve food and quickly eliminate the steel hooks leaving the lead to be more slowly dissolved. A while back their was a program where tackle dealers would exchange non lead tackle for the old lead stuff you bring in. I found a report of an unscrupulous tackle shop reselling the lead tackle after collecting it after being paid for the non lead stuff they gave away in trade. To combat this I took all my lead tackle and melted it down before giving it to a friend who reloads ammo. In general, why wouldn't we eliminate lead for small tackle and do what we can to help the loon population. |

quote DeterminedOrange: Good question. Aside from cost- if it were neutral, I can't think of a reason not too. Sure sinkers and splitshots have to be larger- but big deal. The only thing I can see it impacting would be jig heads and needing to use a larger jig. |

My next point has to deal with eagles. They are so prevalent now and love to eat baby loons. My parent's lake has a pair of loons that nest every year in their bay. This was the first year in EIGHT years that an eagle didn't get the chick. They don't kill the chick after it's hatched either, they let it fatten up for a few weeks first. Makes me kind of hate eagles. Sorry America. |

quote AndySG: "It is hard for me to believe a loon would eat a jig head. After all, they have a hook attached to them, right? If a loon were dumb enough to eat one, it would likely choke them to death rather than poison them. Also, 80% of a loon's diet is small fish. Maybe the fish are full of jig heads, but I doubt it. Since loons also forage for crustaceans and insect larvae, its likely they are picking up some lead shot. After all it has been used for centuries by waterfowl hunters and the wet lands are full of it.Totally agree |

quote arctic: "Masterangler, The use of the term "Climate Change" is a way better, and more accurate, description than "Global Warming", because a warming climate changes multiple elements of the climate, including rain and snowfall, wind patterns, length of growing seasons, etc. Yes I agree that the scientific method cannot prove or disprove the existence of a supreme being. Rather I only need look around at the very creation for it clearly declares the existence of a designer. To conclude that what is visible occurred via happenstance is fantasy land. What say you about the computer projections being way off? Much of the clamor concerning the theory of climate change was predicated on the computer models. IMO that is why the haste to secure power is so forceful. It is why they continually say "the debate is over". As time goes on and the climate does not behave as per scientific and computer models the theory will be disproven. Since when has science ever said "the debate is over"? Doesn't sound like something a scientist would say. As per the change from Global Warming to Climate Change.........you may accurately point out the advantages of a more precise terminology but I still disagree why the change was made. If the earth was warming as per the computer models then I believe Global Warming would still be in play. It simply sounds more ominous. The language was changed IMO so no matter if it is hot or cold, flood or drought, then it can be blamed on mankind. And if the populations can be convinced of imminent demise then they will empower governments and cede all power to a select few. It is the biggest con in the history of mankind with lots of disparate interest groups with varying motives frantically pushing it. Are you aware that the originator of global warming, Berkeley professor Rodger Reville, largely recanted his own work and was shocked that such a political movement was developed via his work. He suggested far more study. Of course the powers that be largely smeared him saying that he was old and feeble of mind (the destruction of the naysayers). We can however agree that less gunk in the air is a good thing. I am all for pollution controls for a cleaner healthier environment. What I am not for is giving politicians complete control over our industry and markets via carbon credits. Such a move would certainly result in poverty and misery..........We can all meet in the rice paddies if the population gives the masterminds (utopian statist) control. It is the "Road to Serfdom" (an excellent read BTW). |

The Scientific Method can help us understand the impact of 7 billion people on the climate of the Earth--- but cannot prove, disprove, or characterize any of the gods that mankind has invented over the many millennia. |
