Causes of Common Loon Mortality

Number: 1994-02

 

WHEREAS, there are human-induced causes of mortality and other sub-lethal effects for the common loon (Gavia immer), including, but not limited to oil spills, shoreline development, acidification of lakes, entrapment in commercial gill and trap nets, lead poisoning, and other human-induced causes of loon mortality and morbidity; and

WHEREAS, there are many natural causes of loon mortality such as botulism and predators; and

WHEREAS, there has been considerable discussion recently on the issue of lead-induced loon mortality; and

WHEREAS, regulations are being pursued which will impose restrictions on the use of lead for fishing tackle;

NOW THEREFORE, BE IT RESOLVED, that the National Wildlife Federation, gathered at its annual meeting assembled March 4-6, 1994 in Austin, Texas, recommends a complete investigation by the U.S. Fish and Wildlife Service that will identify the causes of loon mortality and sub-lethal effects from human-induced factors and natural factors; and

BE IT FURTHER RESOLVED that appropriate agencies and native organizations be requested to address these human-induced impacts on loons.
