觀察細節
After re-evaluating the photos of these two birds, they appear to have some unique differences from nearby Tundra Swans. The base of the bill appears more pointed where it meets the eye and head has a comparable look like the Canvasback. The dingy feather colors of the TRUS tend to last longer than those of the TUSW. This species has been identified at this location for several days.
