Description

This is a compilation of previously-documented and newly-discovered records of the western grebe in Alberta through 2016. The report greatly expands the number of lakes known to be occupied during the breeding season to 318, from a previous estimate of 80. The report suggests that western grebes are more abundant and widespread in Alberta than previously thought, and that the current status of "threatened" may require re-evaluation.
