Common loons threatened by declining water clarity

The Common Loon, an icon of the northern wilderness, is under threat from climate change due to reduced water clarity, according to a new study. The study followed up an earlier paper that showed substantial reproductive decline in the author's study area in northern Wisconsin.

Piper, in collaboration with Max Gline and Kevin Rose from Rensselaer Polytechnic Institute, reports several important findings. Over the past 25 years, there has been a consistent decline in water clarity. During the same period, body weights of adult males, adult females, and chicks have also declined.

"Few animals on Earth are at once so beloved and so poorly understood as Common Loons," Piper said."This partnership between a loon behaviorist and lake ecologists who collect satellite data on water clarity has given us a unique and powerful window onto foraging efficiency and the loon population as a whole that might help us conserve the species."
