IUCN Status
Least Concern
The black-necked swan is the largest waterfowl in southern South America.
They are one of the fastest fliers of the eight swan species, often reaching speeds of 50 miles per hour.
Grace in Water, Awkward on Land
These birds spend most of their time in the water. They are excellent swimmers, but are awkward walkers on land. Their bill has special jagged edge that helps them tear through tough or slippery vegetation.
Cob, Pen, and Cygnet
The male is referred to as the cob, the female as the pen, and the young are called cygnets. They are aggressive and very protective birds.
Status
Common and widespread; not globally threatened. Habitat loss, including draining of many marsh and wetland areas, continues to be the largest threat to this species.
