164 Ontario Birds December 2021 limited because of the relative paucity of Red-breasted Mergansers at large, coastal seabird colonies where most Great Black- backed Gull predatory activity have been documented.

ACKNOWLEDGEMENTS I thank the editorial team for their helpful comments that improved the manuscript. Also I thank Ron Pittaway for encouraging for me to submit a paper to this journal.
