**Rare, though status obscured by released/”park” birds. Adult type (maybe SY/TY by bill color and bill knob size) mixed in with the Trumpeter Swan group in the field north of the checklist location along the highway; swan roughly the size of surrounding Trumpeter Swans, often holding its neck in a “S” curve, with a knobbed, pinkish orange, and black bill. The bird lacked bands on both of its legs, had at least a hallux on its left leg, and was generally as wary as the Trumpeter Swans it was with. These features along with its presence in a group of wintering Trumpeter Swans in combination with an apparent increase of Trumpeter Swans from the “Interior population” [closer to the “expected” range of Mute Swans in North America] (https://birds.outdoornebraska.gov/large-increase-in-number-of-wintering-trumpeter-swans-in-nebraska-2013-2023/) makes me think that natural vagrancy is a possibility for this individual versus the undoubtedly released individuals that show up somewhat regularly at lakes inside the Omaha city limits.
