Cygnus olor

Length: 50-59 in Weight: 12-30 lbs

Identification:

Distinguished from other swans by a vivid orange bill. A large white bird with black feet and a black mask. Often swims with its neck in an S-shape and its wings slightly raised, giving the back a frilled appearance.

MUSW

Distribution: 

Not native to the United States, but wild populations are now established throughout the continent, particularly along the Atlantic Coast and Great Lakes. Captive birds are commonly seen in parks.

Cool Facts:

Mute swans are viewed in many cultures as a symbol of love, and are the classic swan featured in many ballets, fairy tales, and even the classic story of The Ugly Duckling.

Though many people would consider Mute Swans to be a beautiful addition to any pond, their aggressive nature frequently causes problems for native species, and they can even be a danger to humans who get too close.

Fresh Off the (Science) Press:

Exotic Mute Swans can potentially impact native waterfowl by depleting food resources (Mute Swans can eat up to 8 pounds of aquatic vegetation a day!), or through their aggressively territorial behavior (Gayet et al. 2014). However, Mute Swans do not always have detectable negative impacts on the ponds they call home (Gayet et al. 2016), and many members of the general public are opposed to active swan management (particularly of the lethal variety) due to their cultural value (Jager et al. 2016). All these factors make Mute Swan management an ongoing challenge.
