Comments:

Survey methods are generalized across the different grebe breeding lakes because they were not specified per lake but an aerial survey was initially conducted. Survey was at least once in 2014 or 2015 with no further detail on each lake. Grebe breeding pair totals per county and per lake is reported. Entered is the grebe breeding pair total per breeding lake X2 for an estimation of adults numbers. Average colony size for Logan County is entered but no nest numbers per breeding lake is reported.

Comments:

Larry Igl confirms that Western grebe (or Western and Clark's grebe) colonies were at this lake in the past. No years nor further details or whether grebes still breed there. Larry believes that there are probably more ND lakes than is listed here that support grebe colonies.
