CALL OF THE LOON
"STOP USING LEAD, PLEASE!" It would be hard to imagine a northern Wisconsin lake without them. Their haunting calls and timid nature make them an icon for almost any lake. Loons are one of the most enchanting birds in Wiscsonsin and it's no surprise that they capture so mcuh attention. The loon is an important symbol of our state and a high public interest in loons had lead to increased conservation efforts. Loons are considered one of the most primitive birds on earth because they have not changed from their current form for the last one million years. There are only five species of loons in the world, with the common loon being the only breed to reside in the lower 48 states. These birds call Wisconsin lakes home from April until they depart in late August or September for warmer climates of the Atlantic Coast and Gulf of Mexico.
Loons are a very particular bird and not just any lake will do when selecting a nesting site. Lakes that are 50 acres or smaller (slow, no wake lakes) are most often chosen, with most loons needing at least a 10 acre lake for room to take off. Loons, like those that visit North Sand Lake, will chose one of the bays for nesting.
Loons, like many other water birds, do not have teeth and have to swallow their food whole. Lead is a TOXIC METAL that attacks the nervous system and reproductive systems of loons and other water birds. A poisoned bird will exhibit signs of being disoriented, skinny or lethargic. Loons that ingest lead often die within 2-3 weeks. In addition to direct ingestion,loons can suffer from leading poisoning after eating fish that have ingested lead. A study done by the Minnesota DNR discovered though individual fishermen lose only small amounts of tackle on each fishing trip, it does add up to a large amount of lead being left behind in lakes. It is estimated that more than 1 ton of lead was deposited in 5 Minnesotat lakes during the summer of 2004. In addition, research since 1987 on loons from 6 New England states has shown 44% of dead and dying adult loons had lead poisoning, with virtually all cases pointing to lead tackle as the culprit. Another 15-year study in Michigan revealed that lead poisoning, primarily from lead jigs, was the number one cause of loon death at 24% of overall mortality. Here in Wisconsin the DNR Health Program reports an even higher rate of 30% dead loons submitted having lost their lives from lead poisoning. Stopping the deadly effects of lead poisoning for some of Wisconsin's most treasured feathered friends is surprisingly simple. First, anglers can stop using lead sinkers, jigs, split shot and other fishing equipment that is made from lead. There are a number of lead-free alternatives that are not very costly, which include steel, tin, tungsten, bismuth, pewter, ceramic, densified plastic and glass materials. Second, when disposing of your lead tackle, do it properly. Do not throw lead tackle away in a lake or trash can. Instead, take it to your local household hazardous waste collection site or scrap metal collector. Third, SPREAD THE WORD! Contact your local bait and tackle dealers and encourage them to stock lead-free tackle. Let your fishing friends know about the negative impact that lead tackle has on not only loons, but on the entire lake ecosystem. Loons are an icon of northern Wisconsin and deserve a safe home on our treasured lakes. With the help of Wisconsin's anglers, lake owners and citizens, the loon will remain on Wisconsin lakes for years to come. Article written by Katie Boseo, UW-Stevens Point-undergraduate student.
