Description
The trumpeter swan is the largest extant species of waterfowl. Adults usually measure 138165 cm (4 ft 6 in5 ft 5 in) long, though large males can exceed 180 cm (71 in) in total length.[2][4][5][6] The weight of adult birds is typically 713.6 kg (1530 lb). Possible due to seasonal variation based on food access and variability due to age, average weights in males have been reported to range from 10.9 to 12.7 kg (24 to 28 lb) and from 9.4 to 10.3 kg (21 to 23 lb) in females.[2][7][8][9] It is one of the heaviest living birds or animals capable of flight. Alongside the mute swan (Cygnus olor), Dalmatian pelican (Pelecanus crispus) and Andean condor (Vultur gryphus), it is one of the handful to scale in excess of 10 kg (22 lb) between the sexes and one survey of wintering trumpeters found it averaged second only to the condor in mean mass.[10][11] The trumpeter swan's wingspan ranges from 185 to 250 cm (6 ft 1 in to 8 ft 2 in), with the wing chord measuring 6068 cm (2427 in).[2][4][5][12] The largest known male trumpeter attained a length of 183 cm (6 ft 0 in), a wingspan of 3.1 m (10 ft 2 in) and a weight of 17.2 kg (38 lb). It is the second heaviest wild waterfowl ever found, as one mute swan was found to weigh a massive 23 kg (51 lb), but it has been stated that was unclear whether this swan was still capable of flight due to its bulk.[13]
The adult trumpeter swan is all white in plumage. As with a whooper swan, this species has upright posture and generally swims with a straight neck. 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, measuring 10.512 cm (4.14.7 in), is up to twice the length of a Canada Goose's (Branta canadensis) bill and is the largest of any waterfowl. The legs are gray-pink in color, though in some birds can appear yellowish gray to even black. The tarsus measures 10.512 cm (4.14.7 in). The cygnets (juveniles) are grey in appearance, becoming white after the first year.
The mute swan, introduced to North America, is scarcely smaller. However, it can easily be distinguished by its orange bill and different physical structure (particularly the neck, which is always curved down as opposed to straight in the Trumpeter). The mute swan is often found year-around in developed areas near human habitation in North America, whereas Trumpeters are usually only found in pristine wetlands with minimal human disturbance, especially while breeding.[2] The tundra swan (C. columbianus) more closely resembles the Trumpeter, but is significantly smaller. The neck of a male Trumpeter may be twice as long as the neck of a tundra swan.[2] The tundra swan can be further distinguished by its yellow lores. However, some trumpeter swans have yellow lores; many of these individuals appear to be leucistic and have paler legs than typical Trumpeters.[14] Distinguishing tundra and trumpeter swans from a distance (when size is harder to gauge) can be challenging without direct comparison but it is possible thanks to the trumpeter's obviously longer neck (the great length of which is apparent even when the swan is not standing or swimming upright) and larger, wedge-shaped bill as compared to the tundra swan.

What a beautiful pair. The gentle wave around the leading swan, and the soft ripples with reflections are all so very soothing and peaceful to the mind Elizabeth. Great capture. L/F
