Trumpeter Swan
Cygnus buccinator
Species of Conservation Concern
Family:
Anatidae (ducks, geese, swans) in the order Anseriformes
Description:
An all-white swan with a wingspan of nearly 8 feet. They fly with their extraordinarily long necks outstretched. Distinguished from tundra swan by its straight upper bill and the broad base of the bill against the eye, making the eye appear as part of the bill from a distance. Voice is a low trumpetlike sound; that of the young is higher and more nasal.
Size:
Length: 60 inches (tip of bill to tip of tail).

Trumpeter Swans Flying Over Water
It’s rare to see these large native geese in our state, though hopefully they will become more common in the future.

Habitat and conservation:
Formerly a common migrant statewide and summer resident in northern Missouri. Currently, individuals and family groups winter in Missouri, foraging in shallow water. Some birds may be from the wild population of the Nebraska Sandhills, but most are from captive breeding programs. If you see trumpeter swans with neck collars, use your binoculars to see the color and numbers of the collar, and report them to the Missouri Department of Conservation.
Foods:
Trumpeter swans forage in shallow water on aquatic vegetation, roots, seeds, and insects.
Distribution in Missouri:
Statewide.
Status:
Rare winter resident at marshes, lakes, and rivers; formerly a common migrant statewide and summer resident in northern Missouri. A Species of Conservation Concern, it is considered critically imperiled in our state.
Life cycle:
Trumpeter swans breed usually in freshwater habitats with dense emergent vegetation, as in inland waters and ponds. Nests are constructed of emergent vegetation and feathers, on the ground surrounded with water. Four to 6 eggs are laid; these are incubated for 33–37 days, and the young fledge in 91–119. Breeding in Missouri is extremely rare but may become more common in the future.
Human connections:
There are only about 5,000 trumpeter swans in the Midwest, and they are considered extirpated from our state. Hunters who shoot trumpeter swans risk thousands of dollars in fines and possible jail. If you’re hunting snow geese, make sure you can distinguish between them and trumpeter swans!
Ecosystem connections:
Swans, geese, and other aquatic grazers are important components of wetland, pond, and lake ecosystems, pruning the steadily growing vegetation and insect populations. In turn, these birds, especially their vulnerable eggs and young, provide food for carnivores.

About Birds in Missouri
About 350 species of birds are likely to be seen in Missouri, though nearly 400 have been recorded within our borders. Most people know a bird when they see one — it has feathers, wings, and a bill. Birds are warm-blooded, and most species can fly. Many migrate hundreds or thousands of miles. Birds lay hard-shelled eggs (often in a nest), and the parents care for the young. Many communicate with songs and calls.
