Lead is the metal of choice in ammunition and tackle because of its low melting point, its flexibility, and its low cost compared to alternative metals. In 2013, the US Geological Survey found that the weight of lead ammunition and tackle produced that year weighed about one-and-a-half times the weight of the Titanic.
According to wildlife ecologist Susan Haig, birds ingest lead in different ways. Common loons, for example, swallow lead sinkers and jigs, perhaps mistaking them for prey. Other birds eat lead pellets or fragments as grit to aid in digestion. Scavengers including condors and eagles often feed on carcasses of animals killed by hunters and subsequently ingest lead fragments. The impacts can range from lethargy and eating disorders to reproductive issues and even death.
