Comments:

From Table A.2, maximum counts of breeding Western grebes from surveys mostly conducted during nesting season from June and July from 1991 to 2011 (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 Unpublished report for the Canadian Wildlife Service). No break out of data per year or other details.

Survey Citation:
Erickson, M. E. 2010. Persistence and abundance of the western grebe in Alberta. Dissertation. University of Alberta. Edmonton, Alberta, Canada. Same lakes and abundance estimated were checked against Erickson, M. E., C. Found-Jackson, and M. S. Boyce. 2017. Habitat associations with counts of declining western grebes in Alberta, Canada. Avian Conservation and Ecology. 12(1):12. Appendix to Erickson et al 2014 is unavailable but presumed to be the same list of lakes and abundance estimates.

Comments:

From Table B.1 and Table C.1, survey method and date for 2008 field season, and latest abundance estimate from 2008, which is the same as maximum abundance estimate. Source of maximum abundance estimate is from the 2008 field data. However, Table B.1 says data is obtained from the Alberta Sustainable Resource Development (ASRD) so this is a little bit confusing. Either way, very small count.
