Molts. — Young swans apparently have partial molt succeeding juvenal plumage dur- ing or after first winter, and complete molt in succeeding autumn, after which or during the following season most of them probably assume white plumage of adults, though per- haps not fully mature and in some cases showing some grayish feathers; adults have complete post-nuptial molt beginning in late July or in August, when flight-feathers and tail are shed; probably the Trumpeter molts as do other swans. Field Marks. — Adult like Whistling Swan but much larger; probably indis- tinguishable from it in the field, except close at hand, when black unmarked bill can be plainly seen; lack of knob at base of upper mandible distinguishes Trumpeter from or- dinary park swans (Cygnus olor Gmelin). Young in spring: Has the body grayish-brown or brownish-gray, while young of Whistling Swan has body dirty white.
