觀察細節

Swans had a straight black (culmen) bill with no yellow, and pinkish line. Angle of base of bill straight. Eye not distinct from bill. Larger than the tundra swans they were mixed in with. Back appeared more "bulbous", less flat than Tundras. Apparently a group of similar size has been seen at the same location in recent days. Seen from cemetery, looking east, down at Pit River. See photo.
