Comments:

This report was focused on Franklin's gull colonies but other waterbirds, such as western grebes, were counted as nesting in association with them. These are minimum counts of western grebes and not the target species so uncertain if this entry should be included.

Comments:

From Appendix D, data columns are historical high count, high count since 2000, and most recent count per colony name in these large lakes with multiple colonies. Since minimum count was not stated, I entered the minimum from these columns though it might not be the actual minimum across the span of years reported. Also, there is no detail on years that were excluded from surveying so range of survey years may be inaccurate. The highest count of 2020 is 82 from eBird (https://ebird.org/canada/checklist/S69534269). Threat described as changes in water level but doesn't specify if too high or too low.
