Even the MN "study" points out that almost no scientific work has been done on the impact of lead on upland birds.
Short memories, I guess . . . The eagle was used as a "poster bird" (along with waterfowl, obviously) during the push for nontox for waterfowl. Well, since then, eagles are absolutely THRIVING. Their recovery is one of the great successes in modern wildlife management. It would seem that if the lead we continue to use in the uplands were a real problem, then we would not have seen eagle numbers grow as they have.
Also, how about wild turkeys? They do about as much pecking around on the ground as any game bird. Again, they are thriving to such an extent that they now exist, in good numbers, in places where they disappeared (or perhaps had never been?) long ago. If lead were a serious issue, wouldn't it have impacted them?
And apparently the authors of that resolution haven't noticed that lead prices are dropping.
Some people, acting in the guise of "conservationists", are far too eager to shoot hunters in the foot. With steel.
