COSCOROBA SWAN

Scientific Name: Coscoroba coscoroba
Order
Anseriformes

Family
Anatidae

Habitat & Range
The coscoroba swan is native to South America and inhabits Chile, Argentina, Tierra del Fuego and the Falkland Islands. In the winter, they fly slightly north to Uruguay and Brazil. Their preferred habitat is a well-vegetated swamp or lagoon.

Identification
A corsocoba swan’s plumage is almost completely white, with the exception of the outermost tip of the wings, which have black feathers and are only visible when the wings are open. The beak, legs and feet are red. The average weight of an adult is 9 pounds and length ranges from 34 to 45 inches with a wingspan of about 62 inches.

Diet
Coscoroba swans are omnivorous, feeding primarily on various grasses and small water plants. They will occasionally consume a small fish or mussel.

Reproduction & Lifespan
While the female incubates the eggs, the male stands guard and aggressively protects the fledging from predators after hatching. Eggs measure approximately 75 mm and weigh an average of 170 grams.

The lifespan of a coscoroba swan is estimated at 20 years.
