Watching this site I am generally impressed with the mostly level headed responses to most of what comes up. The point of this topic is to ponder and ask how and where people get their factually based information and ideas?

I try to offer up advice or perspectives based on a fair amount of experience, when my experience is limited compared to those weighing in that obviously have more I try to learn, not talk. I especially am interested in those who qualify their perspective based on telling how and why they know what they know, that means way more when the expertise was based on extensive exposures to something.

On another site there was quite a debate going on about wyoming wanting to ban lead shot (banned just about everywhere else). Basically I was seeing some of the lamest ideas about lead not being harmful to animals, especially birds you could imagine.

I am a pure gun loving nut, I've competed in a vast array of shooting sports that necessitate specialty high quality firearms. My wife is a bird specialty veterinarian with extensive commercial experience, this has exposed me to an incredible degree of knowledge (more than I ever wanted to know) about birds and what can hurt them.

Lead is the bane of birds, if a pet bird has a cage with lead paint it will get sick. If the bird eats something like just chewing on a lead glass decorative frame and gets just a few tiny pieces in it's gizzard it will be severely ill in a day and dead in a few if nothing is done. The clinical signs of lead toxicity are so specific and easy to spot with experience that my wife can more often than not make the call before running conclusive lab work like x-rays which show the little specks of lead like little black spots in the gizzard.

Jeanne has had clients who have had their ponds destroyed for ducks and geese by shooting skeet or trap over the pond. On a migrant population where waterfowl is passing through you will not notice the effects. One or two #8 shot will cause neurological signs like staggering when walking or not flying right. This is a death sentence for a wild bird who will be picked off by a predator.

I was using a tree out back off the deck as a backstop for pellet rifle shooting and there was a fair amount of flattened pellets at the base of the tree. We had a bird feeder up in that tree and our turkey population came through in the afternoon and gobbled up any grain on the ground. I didn't even think of the pellets, but my wife asked me if I was shooting pellets anywhere that the turkeys could get them. I asked why and she said she had seen about half a dozen turkeys in the flock of 80 or so that were acting wobbly in a way that looked like lead toxicity.

I fessed up and told her where I was shooting, we went and looked and sure enough there were pellets on the ground where the turkeys would eat them. Birds will eat all kinds of rocks and whatnot to help their gizzards grind up what they eat, the gizzard keeps a constant high level of lead in their system because the lead is soft and gets quickly ground up against rocks and released in their system.

So while I have seen plenty to know that concerns for wildlife and lead shot are not exaggerated in the least I wanted to share my experiences with just how bad it really is thinking that the information coming from a fellow shooter and enthusiast means more than from questionable or anti gun sources. One further credential as far as my wife is concerned is that she is not a liberally based anti hunting or shooting type at all. She has testified at three senate hearings and numerous county and state issues against PETA and other pro animal rights activists trying to get animal legislations against industry and private citizens rights to have or use animals.

I was branded a liberal anti gun person because of my factually based perspective on the realities of the issue. People who enjoy any sport or hobby such as hunting have a responsibility to act as stewards of their environment and wildlife.

People scare me that form an opinion like lead shot bans being a conspiracy to take our guns without being able to differentiate valid environmental concerns against poorly based "beliefs". Those people have zero ability to differentiate fact from rhetorical lines on anything.

I try to use bullets that go through ground squirrels in one of the places I shoot because eagles snap them up as soon as they are shot. It's actually pretty interesting, seagulls eat the guts and leave the bodies for the eagles. A .17 HMR doesn't leave much behind. :D I shoot deer for meat and generally use a head shot.

Read it on the internet :D

I am curious about:
wyoming wanting to ban lead shot (banned just about everywhere else).

I thought it was federally banned for waterfowl - or are you talking about upland birds?
 
There was some big controversy on the GB forum where they were all up in arms about Wyoming or Montana succumbing and going to a lead shot ban. It may be there is a federal ban on federal land, but it was my understanding the shot ban was state by state with only a few that had not followed suit. You had states that paved the way and others following suit. It's because the danger to birds is real.

It may have been Montana, it was a low population state where they take great pride in less government "control".

My main point was that it is ignorantly informed people that can't seem to understand the process of getting fact based information with which to form their opinions. These people refused to accept that lead can be bad for birds.

California was one of the first states to go to non lead shot, I was able to get lead shot in Louisiana way beyond where I could in California.

I agree that hunters have a responsibility to the environment and the animals that sustain themselves from it.

but to answer your question, I get my info from the DNR here in Minnesota. they specifically ban the use of lead shot when hunting water fowl, as it is harmful to them and the environment.
 
There is no doubt that lead is a harmful substance & the absorbtion on lead is cumulative. This is the reason lead has been removed from gasoline & most paints, & is the reason for laws banning the use of lead in food contact products & childrens toys.
Birds are fragile creatures & are effected more so by harmful substances than mammals- the reason miners used canarys as gas monitors.
The cumulative effect of lead shot in waterways is bad for the environment, however I believe the detrimental effect on waterfowl in most cases is overstated.
My 30 years experience & knowledge of lead, its usage & safe handling comes with being the former CEO & owner of a plastics manufacturing company.I employed several industrial chemists that I worked alongside in developing new formulations for industry & the use of heavy metals such as lead, cadnium & barium were all closely monitored.
 
ignorantly informed people that can't seem to understand the process of getting fact based information with which to form their opinions.

Well, that goes both ways, doesn't it? I do not believe lead BULLETS present an issue to wildlife or people, and think the "science" that led to the California lead bullet ban is sketchy science at best, down right deceitful at worst.

The logic that condors are ingesting lead bullets found in gut piles does not ring true, since the vast majority of bullets pass completely through the animal - so there is no lead bullet in the gut pile to eat.

Lead shot in water is bad, and is exacerbated by the fact that ponds get shot over repeatedly. I do not think it is comparable to me walking through the forest and shooting a grouse - the chances of hundreds of shells being shot in that exact location is effectively zero.
 
I think there is some confusion here. The feds mandate that steel shot be used for all waterfowl hunting, regardless of state rules. But there was recently a proposal to mandate non-lead bullets for BIG GAME hunting near Jackson and Grand Teton park on Federal lands. The basis for that proposal is that an elk might get shot and the bullet winds up in the guts. The elk is then field dressed and the gut pile remains behind, where an eagle comes and devours the gut pile, thus ingesting said bullet and triggering an environmental disaster.
 
It's only overstated if you think the fact that three or more #8 pellets is a sure death for a bird is a minor thing.

The numerous different scenarios I've had firsthand knowledge of as pertains to birds specifically is significantly different than manufacturing experts looking at toxic exposures to mainly humans.

Bird eats a #5 or #4 pellet or two, bird shows neurological signs within a few days, bird gets picked off by a predator that lives by recognizing another bird that's not acting right.

That's overstated? I think the EPA understates because it's harder to monitor and assess how wildlife is doing with things like this. The bird gets sick and eaten before any meaningful count can take place. Migratory birds eat pellets from one place and die in another.

We gave a couple we know a very tame pair of parrot type birds. They let them out to fly around the house and one got a little decorative lead glass frame and chewed a few little bitty pieces off. The bird started falling off it's perch to the bottom of the cage. When my wife asked had it gotten anything lead it was just the day before that they knew it had but didn't know to worry. The xrays showed a few pieces smaller than #8 shot. Fortuneately chelating agents and something else that encapsulates the lead can save a bird if caught quickly enough. That bird would have been dead in another day.

It's a bird's nature to eat stones and other hard objects so they have a tendency to eat pellets, when they do they are dead, it's that simple and there's no way to understate it. If we ate lead pellets it would pass through in a couple of days, a bird has them sit in their gizzard where they are constantly being ground up and in their system.

The point I was making was that everyone gets information from different sources and many lock onto whatever they hear even if the source has a bias like trying to represent that there is no real threat to wildlife, it's just misinformation geared to deprive us from having guns. Never could any group of people be more wrong. The funny thing is that this is a group of people prone to having it wrong about a lot of things because this is the way they think and arrive at conclusions, not to mention that it's impossible for them to change their minds.

I wouldn't take the issue nearly as serious as I do if I didn't live with someone who repeatedly get examples of the problem in her face. If you are a hunter it's easy to side with those objecting to interferences to hunting the way you always have, and think a given situation is being overstated.

The problem I think is based on a group of people who are always under attack in some way shape or form, hunters.
We are always going to side with the side that will let us hunt, as your wife is always going to side with whatever is best for her interests, it is human nature.
The science is sketchy at best, they are going to pick the worst polluted place to get test cases it is fact. As we pick the least polluted places to counter. We are going to believe the source that supports our case.

I don't think it is ignoring the facts as both sides have facts that prove the case.
If you hunt you will support the side that is in favor of hunting.
If you work at a bird rescue shelter you will not..

Really, this sucks,,considering we started shooting steel in Wyoming back in ohhh...... 1987

I was fortunate enough to be an engineer in the middle of a bunch of bug-and-bunny PhDs for four years. I did a lot of brain-picking during that time. Since then, I do a bit of monitoring of the results of studies by the biologists of the Texas Parks & Wildlife Commission. I've seen little evidence of any "agenda" other than objectivity in their efforts.

As far as this thread, let's keep shotgun lead shot separate from rifle bullets, okay? Two different deals, seems to me. (But feel free to start a thread with rifle bullets as the subject.)

As far as my own opinion, scattered-out shooting on upland birds doesn't compare in lead-shot hazard to the more concentrated waterfowl shooting. For one thing, natural processes tend to cover the shot--soil erosion, fallen leaves--and farming plows the shot beneath the surface.
 
I have from several pretty well educated and intelligent life sciences professionals that are prety big environmentalists that there is a HUGE difference between pure lead and any sort of alloy or mixed commercial product.

Pure lead, such as used in fishing tackle and shot, is EXTREMELY stable. Absorption rates following ingestion are minimal. The lead will simply pass. Lead will sit at the bottom of lakes for generations without oxidizing, showing signs of weathering, or such(one reason it is used in tackle). Most of the research in this area relates to disproving the theory that Rome fell in part due to lead contamination from pure lead pipes used in the aqueducts. The studies on this have shown it is not very likely at all. The lead poisoning happening from 1900+ was from industrial uses where the lead was not pure.

I don't know any of this information, but I trust the two unrelated people who told me it.

Does a bird who takes two pellets that hit a bone and ?splatter? internally die in 2-3 days from lead poisoning? Maybe, but is it likely to survive after being hit with steel shot? hell no. It is going to get an infection and die on its lonesome or get eaten by something else.

The thing that eats it will pass the lead without issue.

As a lifelong waterfowl hunter, I can say (based on real world observation) that the lead shot ban for waterfowl has resulted in many times the number of birds being wounded and unrecoverable after being shot with ineffective steel shot I would ever imagine could die of lead ingestion.

Also, the elimination of DDT based ag chemicals resulted in a noticeable resurgence of birds. No such effect was seen after steel shot usage was begun.

Banning lead from rifle projectiles used on big game seems like a solution looking for a problem.
 
As a botanist, I see many decisions informed by objective (as much as anyone can be purely "objective") scientific research. I don't think anyone is out to get hunters, at least from the research community. And I know that many wildlife biologists are hunters themselves, so to suggest that lead poisoning is a hoax or the ban on lead shot somehow drives some anti-hunter agenda just seems ludicrous to me. Why would any biologist that hunts, especially waterfowl hunts, want to contribute to such an agenda by falsifying data concerning lead contamination? I admit that I haven't seen raw data concerning lead contamination and waterfowl, but as a member of the science community, which is peer reviewed, meaning you can't get away with absurd claims as research is reviewed by literally thousands of peers, I just don't think that anyone would be trying to drive such an agenda of banning lead shot for no good reason and actually get away with it. And I don't see how "the science is sketchy." People may wound more birds with steel shot, and that is something that is or has been directly observable, but there is no way to directly observe something like "i think that lead shot wouldn't have contributed to as many dead birds as does the use of non-toxic shot." That is speculation.

And folks can't think just in terms of birds. I'm no wildlife biologist (I stick with the plants), but amphibians are as, if not more, susceptible to contaminants as birds. Lately, I've been reading and hearing more and more about amphibian ranges declining, amphibian health issues, etc. It's best to view a marsh (or any environment) as a community. Lots of species rely on lots of other species to make things work.

I know alot about the Calif. ban!

It is a BS attempt at gun control by fabricating stories of condor ingestion of lead bullets. They have never been able to come up with a condor gizzard with a bullet in it, but they got the bill passed!

Hey it doesnt cover shotgun shells! Thats only for migratory birds.
It doesnt cover small game!
It doesnt even cover a logical area!
see link: http://www.dfg.ca.gov/wildlife/hunting/condor/docs/Ridley-TreeCondorPreservationAct.pdf

OK- lets use some logic. Is this likely to happen? a 30-06 bullet, (copper jacketed mind you) that stays in the guts of a deer (explain that to me first), that doesnt get eatin by a bear, mt. Lion, coyote, bobcat, fox, badger, ground squirrel, hawk, buzzard (Cousin to the Condor as they are both buzzards), raven, crow, owl, kestrel, eagle, (bald and golden) before a condor flies from its sheep feeding station (yes, they feed them sheep) to find some guts 100 mi. away?????

Get my point, it hasn't happened and statistically can't. And wait!!!! what about all the other birds that get to the gut pile first? Why arent they falling over dead all over the place??

Oh yea, the state and the Pita folks have spent over $35MM increasing the number of birds from 22 to 381! WOW that only cost $97,500 a bird! and they have only released 192 of the 381 back into the wild. http://en.wikipedia.org/wiki/California_Condor

As the article says they are still losing Condors to EAGLES and powerlines. See any lead there? :barf:

I'm definitely a "from the Horse's mouth" kind of guy. I absolutely hate hear-say and second-hand evidence. When I hear/read about a study, I try to track down the actual published paper, or original source.

That being said-
Ingested copper, and copper oxide (CuO), can be more toxic to many biological systems than lead. Companies (and government entities) and persons seeing copper bullets as the answer may have to face undesirable realizations in their future.

The only truly environmentally friendly projectiles are carbon crystals. Eventually, we may all have to shoot ...diamonds.
 
Nalgi,

We're talking about shotgun shot.

Franken,

Since you said it, I'd like to see the source or publication on copper being more toxic than lead. I'm not saying it isn't...not calling you a liar or anything. I just haven't heard that before. I'd just like to know what your source is.

Thanks
 
Ask anyone with an aquarium if its OK to drop a penny in the tank.Copper will even get rid of pesky snails.
For myself,what I truly believe:In terms of environmental agendas,"science" has corrupted itself.It has lost credibility.The Chicago Carbon Exchange has ceased trading.The mods would proibably disapprove of me taking that further.
Some areas in Wyoming permit lead shot for hunting upland birds,but any national wildlife refuge and some other designated areas are non toxic shot only.
I used to live in Aurora ,Ill.They have a street,Galena Street.I delivered papers on that street as a kid.With my hands I could pull ice cube size cubes of lead ore out of the ground.Clearly metalic lead .Why doesn't the EPA and all the anti lead freaks focus on saving Aurora,Illinois?Evacuate everyone,heck,why aren't they all dead? As a matter of fact,as a Boy Scout,I got my Birdwatching Merit Badge in Aurora ,Illinois near Galena Street.How come Aurora,Ilinois can have exposed veins of natural lead AND birds at the same time?
Barn Carpet.
