CROSSLAKE, Minn. (AP) — A researcher attempting to know what’s inflicting a decline in Wisconsin’s loon inhabitants is increasing his undertaking into Minnesota.
Minnesota Pubic Radio reported Wednesday that Walter Piper, a biology professor at Chapman College in California, has partnered with the Nationwide Loon Middle to increase his analysis into Crow Wing County in north-central Minnesota. Final summer time Piper’s workforce hooked up identification bands to about 80 loons across the Whitefish Chain of Lakes north of Brainerd. The workforce plans to revisit these territories this summer time to search out out if the birds survived.
Piper has already decided that Wisconsin’s loon inhabitants has decreased by about 22% within the final 25 years. Chicks are also smaller and younger loons’ survival fee is decrease.
