Handful of times I have come across Red-breasted Mergansers in Banff National Park, as they make their way north to their breeding territory. As this migration season, I normally come across one Red-breasted Merganser, but in 2020 there were 7. In the fall they migrate in larger groups, up to thousands at time. Unfortunately we don’t get to see them in the fall. In the thousands would be quite the site.
