Comments:
From Table A.4, maximum counts of breeding Western grebes from surveys conducted during nesting season from 1970 to 1990 and 1991 to 2011 without breaking those down into years or other details (sourced from Wilson, A. and Smith, P.A. 2013. Distribution and population status of Western Grebes in Canada. Unpublished report for the Canadian Wildlife Service). The 30 from 1991 to 2011 are non-breeding adults.

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. Between 1991 and 2011, no grebes were observed there (Wilson and Smith 2013).
