Ep. 566 – Why are Scientists Banding Scaup, Canvasbacks, and Redheads on Pool 19?
Lesser scaup are one of several duck species in North America that have experienced long-term population declines, and despite decades of research, the exact cause of this decline remains unclear. Because of its profound importance as a spring stopover site for migrating scaup and other divers, Pool 19 on the Mississippi River has played a crucial role in numerous scientific studies. In this episode, PhD candidate Cheyenne Beach and field assistant extraordinaire Jack Johnson join Dr. Mike Brasher to explain why so many divers show up on Pool 19 each spring; what we hope to learn from long-term banding of scaup, canvasbacks, and redheads; and how an ongoing GPS tracking study is helping understand how the invasive faucet snail may affect scaup health and productivity.
