JPR: embedded within large SNGO flock. It was a great study bird; had to eliminate vagrant possibilities and land on rare. Distant enough and unique enough plumage type to require careful study before determining species. Pinkish/orangish bill with dark contour line (especially near the cheek; somewhat recalling formative Tundra/Trumpeter Swan). No internal patterning to the bill. Uniform brownish body plumage. Touch of a flank line, near the rear of the bird. Legs somewhat orangish. Digi-scoped record screen grabs from a video.
