Restore the Call - Washington

Partnered with the Washington Department of Fish and Game (King County), United States Forest Service (Colville District), Spokane Audubon, and Hancock Timber Resource Group, BRI is investigating Common Loon population trends throughout the state. Since beginning annual banding efforts in 1995, BRI has banded more than 90 Common Loons in Washington State.

Lead Investigator: Jim Paruk
Contributing BRI Staff: Lucas Savoy, Chris Persico

 

Project Overview

Project Overview

Our banding efforts allowed researchers to verify that many of the adult loons were dying due to fishing-related activities, such as ingestion of lead tackle, and entanglement in monofilament. Because of these findings, the Washington Department of Fish and Game excluded the use of lead tackle on 10 of the 11 breeding lakes Common Loons use in the state.
 

Overall Study Goals

  • Assist and lead in the capture and color-banding of Common Loons in both the western and eastern parts of the state
  • Collect tissue samples of Common Loons and analyze them for lead and mercury, two environmental toxins that adversely impact loon breeding success
  • Obtain geolocators previously deployed in earlier years to identify migration patterns and winter use areas
Study Goals for 2014

Study Goals for 2014

Research
  • Capture adults and chicks and evaluate their health by testing their tissues for potentially harmful environmental pollutants and contaminants, such as lead and mercury
  • Attempt to recapture loons that had geolocators deployed in previous years
  • Continue to catch and color-mark individuals throughout the state

Outreach

  • Develop outreach materials to assist agencies and others with loon conservation interests.
