Trumpeter Swan

Image Description

The Trumpeter Swan is the largest  species of waterfowl. Adults usually measure 138–165 cm (54–65 in) long, though large males can range up to 180 cm (71 in) or more. The weight of adult birds is typically 7–13.6 kg (15–30 lb), with an average weight in males of 11.9 kg (26 lb) and 9.4 kg (21 lb) in females. The wingspan ranges from 185 to 250 cm (73 to 98 in), with the individual wing chords measuring 60–68 cm (24–27 in). The largest known male Trumpeter attained a length of 183 cm (72 in), a wingspan of 3.1 m (10 ft) and a weight of 17.2 kg (38 lb). The adult Trumpeter Swan is all white in plumage. As with a Whooper Swan, this species has upright posture and a straight neck at all times. The Trumpeter Swan has a large, wedge-shaped black bill that can, in some cases, be minimally lined with salmon-pink coloration around the mouth. The bill measures 10.5–12 cm (4.1–4.7 in) and is up to twice the length of a Canada Goose's bill. The legs are gray-pink in color, though in some birds can appear yellowish gray to even black.  The cygnets (juveniles) are grey in appearance, becoming white after the first year.
