Swan with black bill, straight neck, white body. Used scope to view it from the tower (and, earlier, from the 1st gravel lot). Can rule out Trumpeter Swan based on characteristics of head and bill. The heads on these birds were rounded, not angular. The eyes on these birds were more distinct & separated from facial skin, not blended or swallowed up by the black facial pattern. Where the forehead meets the bill, the pattern is more U-shaped, not V-shaped when viewing the bird head on. I was not able to detect yellow in the lores but visibility was challenging. After sweeping my scope across the lake to look for other birds, I could not relocate the swans. I did not see them in flight.
