When I saw these two species in Michigan a long time ago, I remember beak shape being the best way to tell the difference. Based on that I think both of these are Trumpeter Swans with the long, straight bills.

Based on what I am looking at in Sibley's, my guess is that they are first summer tundra swans. Their backs are pretty white compared to their heads and necks, and they seem on the smaller side when compared to the ducks. But then again, this is just a guess!--Lauren HydeKeenesburg, WeldOn Apr 17, 2021, at 2:25 PM, 'The Nunn Guy' via Colorado Birds <cobirds@googlegroups.com> wrote:HI All - Saw two swans at Loloff reservoir today at noon.
