观察细节
Two adults, three young; rounded heads, smoothly curved intersection of superior edge of upper mandible with foreheads, posterior intersection of mandibles with face containing an angle that created a fairly vertical "drop", one adult with a small yellow spot in black loral region of bill, and reddish/pinkish bills with little to no black at intersection with face on the young birds excluded alternative swans. Marginal photos taken at a long distance included to bolster documentation. If you can enlarge the photos, the yellow spot is barely visible on the bird on the left in the group shot and a little easier to see in the close-up of the lone bird.
