How Healthy is the Loon Population in Northern Wisconsin?

The sample of lakes we cover is now large enough that we can make year-to-year comparisons and learn about long-term population trends. The loon population of northern Wisconsin has been stable during the early 21st century. In the past decade, though, the rate of chick production per territory has fallen. Furthermore, the number of territories in use in our study area among the 200 or so lakes that we cover has also fallen slightly. It is far too soon to panic about these trends, which might well be temporary declines, but we are remaining vigilant. In the back of our minds is the recent scientific report predicting that loons will disappear altogether from northern Wisconsin by 2080.
