Dear Canadian Lakes Loon Survey Participant and Supporter

I’m delighted to share with you an exciting new study that uses 38 years of CLLS data from over 1500 lakes to help explain why Common Loons are producing fewer chicks: Drivers of declines in Common Loon (Gavia immer) productivity in Ontario, Canada. The paper is available in full until the end of July at https://www.‌sciencedirect.‌com/‌science/‌article/‌pii/‌S0048969720332447. Please feel free to have a look.

The study found that declines in the number of loon chicks in Ontario over the past four decades likely result from a complex interplay between damage from acid rain, mercury in fish, and climate change. Similar reasoning may also apply to declines in Common Loon productivity elsewhere across Canada (see our nation-wide study published in 2013 at

Thank you to all our present and past participants who have made this possible! We are also excited to let you know that more research based on your hard-earned CLLS data is coming soon. Please watch for updates this fall and early next winter.

If you are interested in sharing this research with your lake association, please contact me for our blog links as well as social media friendly text and graphics.

Finally, please visit our new website and volunteer portal at . Here we share important information regarding Common Loons as well as the registration links to join the program. 

Stay safe and well.

The HLPOA acknowledge the lands and waters on which we meet, are the traditional homelands of the First Nation, Métis and Inuit peoples. Our beautiful lakes are fed from the north and flow to the south. We therefore acknowledge the Algonquin and Mississauga peoples as well as the governance of the Williams Treaties. We wish to express gratitude to Mother Earth, the resources we are using, and honour all Indigenous people who have been and continue to live on these lands.
