The Canadian Lakes Loon Survey was initiated in Ontario in 1981, and expanded nationally in 1989.
Human disturbance and development are ongoing threats to loons. Canadian Lakes Loon surveyors report many activities that are detrimental to loons including: disturbance of nesting sites (as a result of boats, canoes/kayaks, personal watercraft, and water level changes); entanglement in discarded debris (fishing lines and domestic garbage); nest predation due to attracting and support of nest predators (raccoons, skunks, and gulls); and displacement of loons through habitat loss. Reproductive success data from the Canadian Lakes Loon Survey clearly show that the number of chicks that each pair produces each year is declining over time.
Loon reproductive success is a sensitive indicator of the overall health of a lake, while signs of trouble from animals lower down on the food chain may be more subtle. Adult Common Loons typically return to the same lake year after year, so breeding pairs and their chicks feed almost exclusively on their nesting lake. Thus, declines in reproductive success on a particular lake are likely due to problems on that lake, and not from elsewhere (e.g., on wintering grounds or while migrating north in the spring). We know these things because of Bird Studies Canada’s Canadian Lakes Loon Survey (CLLS). CLLS participants have monitored Common Loon reproductive success each year since the early 1980s in Ontario, and nationally since the early 1990s. Participants also collected information on the number of breeding pairs on particular lakes, and what influences their reproductive success. Fortunately, Common Loons are easy to identify and fun to watch throughout the summer, making CLLS participation both easy and popular.

In addition, a report published by the National Audubon Society in the United States in 2014 indicates that loon recovery is threatened by climate change. You can read a summary of the report in the Ottawa Citizen article: “Climate change will disrupt hundreds of North American birds, study says“, published September 9, 2014.
Taking part in the Canadian Lakes Loon Survey (CLLS) is an excellent way to enjoy watching loons over the summer while contributing to loon research and conservation. To track loon chick survival through CLLS, you need to be at a lake in an area where loons breed at least three times over the summer:
– in June to watch for pairs of loons occupying the lake
– in July to look for newly-hatched chicks
– in August to record the number of chicks that have survived the summer
Each participant is provided with a survey kit and detailed instructions that explain the survey protocol.
All participants receive a paper kit by mail in mid-May (up to mid summer for late registrants), that can be submitted by mail or online by 15 September.
The CLLS is a project of Bird Studies Canada (BSC), a non-government, not-for-profit organization. Participants are asked to join as members of BSC. A tax-receiptable membership fee of $35.00 helps to offset the costs of the survey, and includes all membership benefits such as quarterly issues of BSC’s publication, BirdWatch Canada.

McGregor Lake loon count coordinator
Ms Hania Grabowski is the current McGregor Lake Loon count coordinator. If you’d like to participate in the annual loon count, which takes place usually twice during the summer, in June and August, please get in touch with Hania via firstname.lastname@example.org.
Results of McGregor Lake’s Loon Watch July 2020
On July 18, 2020, a sunny and warm Saturday, the first count of McGregor Lake’s Loon Watch was held.
A count earlier in the spring wasn’t held due to Covid concerns, however, with this July count and another later in August we will have sufficient information to report our annual findings to Birds Studies Canada Canadian Lakes Loon Survey as we have for several years.
The count included eight (8) Adult Loons and one (1) baby loon. This single young had first been sighted on July 8th near Île Cornu and had already significantly increased in size. Sightings were otherwise of single loons, scattered around the lake in areas such as Île Bankhead, Baie McCarthy, Baie Gunville, Baie Zurenski and Millionaires Bay.
After the Loon Watch, we enjoyed a wonderful “Looney Regatta” in the middle of the big bay, celebrated with lots of laughter and comradery by participants in five vessels.
Of course, the loons must had known we are counting because the very next morning one volunteer reported a ‘loon party’ of 6!
Thanks to all participants and in particular to our coordinator Hania Grabowski.
Results of McGregor Lake’s Loon Watch August 2020
The second Loon Watch of 2020 was held on a warm and sunny August 22nd. The earlier forecasts had threatened rain for most of the week, so a warm sunny day was a real gift. The volunteers included: Bill and Liz Metz, Mary Carman and Bill Leslie, Amy Jane Lawes and Paul, Nadia and Mike Hall, John Freeth and Marilyn Albert, Sylvie Halde, Deborah Doherty and Allan, Jean Marc Pellerin, Russell Williams and your Loon Watch Coordinator, Hania Grabowski and Rick Mundell. Absent with best wishes were David and Pennie Younger and Sylvie Gravel and Denis Dessureault.
- 4 loons near Ile Coupland: one in the channel and three bordered by the road;
- 3 loons in Baie Courville area;
- 2 loons off the Metz swimming area, towards the Narrows;
- 2 loons near Baie Zurenski;
- 1 Loon on the north side of Bay Laurin; and,
- 1 loon near Ch. Vaillancourt.
A big thank you to all our dedicated volunteers! And a special thanks to all those participating in the Loon Watch by kayak, which provided lots of exercise, particularly for Sylvie Halde who participated by kayak despite a broken leg! Now that’s dedication!
Results of McGregor Lake’s Loon Watch 2019
The first Loon Count of 2019 took place on the morning of Saturday June 22, 2019.
All 10 zones of the lake (see map) were surveyed, with a total of seven (7) adult loons spotted, including two loon pairs, as follows:
- zone 4: 1 adult loon
- zone 5: 3 adult loons
- zone 7: 1 adult loon
- zone 9: 2 adult loons
Despite the tough spring conditions (spring flooding, high water levels, cold & wet spring), one nest was observed with two eggs in it! We’ll be keeping an eye out to see how those chicks fare in the coming months. The next Loon Count is currently scheduled for August 17. Stay tuned for more updates.
A great big thank you to our 15 volunteers who participated in the May 2019 Loon Count: Hania Grabowski & Rick Mundell (zone 1), Bill & Liz Metz (zone 2), Mary Carman & Bill Leslie (zone 3), David & Pennie Younger (zones 4 & 5), John Freeth & Marilyn Albert (zone 6), Sylvie Halde (zone 7), Deborah Doherty (zone 8), Sylvie Gravel & Denis Dessureault (zone 9), & Frank Charette (zone 10).
The second loon count took place on the misty morning of August 17, 2019. The Loon Watch participants had to dodge rain clouds as they conducted the second survey which resulted in sightings of 12 loons in total, including 11 adults and one teen loon. A very healthy population for McGregor lake!
Many thanks to our hard working participants: Amy Jane Lawes, Bill Metz & his sharp-eyed cousin, Mary Carman & Bill Leslie, Nadia & Mike Hall, John Freeth & Marilyn Albert, Sylvie Halde, Sylvie Gravel & Denis Dessureault, & Jean Marc & Ann Pellerin.
Results of McGregor Lake’s Loon Watch 2018
The first loon watch of 2018 was held on June 16, 2018. Six (6) adult loons were observed on McGregor Lake. At the second loon watch that was held on August 11, 2018, seven (7) adult loons were observed. Sadly, there were no loon chicks this year. This may be due to several factors, including: the May ice storm during the nesting period, the early and persistent hot weather, aggressive wave action too close to our shorelines or the presence of Canada Geese who are can be very territorial. Big thanks to our participants: Amy Lawes, Bill Metz, Mary Carman, Jean-Marc Pellerin, Hania Grabowski, and David Younger.
Results of McGregor Lake’s Loon Watch 2014
Loon watches were conducted on one morning in July and one morning in August 2014. In July, five (5) adults and two (2) chicks, were observed; and in August, eight (8) adults and the same two (2) chicks were observed. Participants in the surveys were Hania Grabowski and Rick Mundell, Mary Carman, Bill Metz, John Freeth and Marilyn Albert, Carol Bradley, Jean-Marc Pellerin and David Younger.
