Loons, Lines, and Lead

Author: J.K. Ulrich, Bird TLC Volunteer

Alaskans with and without feathers enjoy fishing beneath the midnight sun, but the tackle human anglers use often proves fatal for birds, especially loons. These iconic waterfowl “are extremely susceptible to lead toxicity due to their feeding behavior," says Bird TLC veterinarian Dr. Karen Higgs. Loons can mistake sinkers for fish, or for the small pebbles they swallow to help digest their food. Just one sinker can kill a loon. Accidental ingestion of lead fishing tackle causes up to half of all adult loon deaths.

Although Bird TLC has treated several birds with lead poisoning, most victims don’t show symptoms until it is too late. The best way to keep lead out of birds is to keep it out of tackle boxes. Loons, Lines, and Lead, an Anchorage-based conservation initiative, recommends two simple steps anglers can take to help preserve Alaska’s ecosystems:

1. Switch to non-toxic tackle made from materials like steel, glass, tungsten, and tin.

2. Properly dispose of used monofilament so it will not entangle and harm wildlife.

Bird TLC is proud to partner with this effort. Learn more about loons, lead, and responsible fishing in this month’s issue of Senior Voice Alaska.
