March 30, 2015 – Black-necked Swan (Cygnus melancoryphus)
Requested by: taylorrbranham
These large swans are found in saltwater and freshwater areas of southern South America, sometimes reaching the Antarctic Peninsula and surrounding islands. They eat aquatic vegetation and occasionally insects and fish eggs, using their long necks to graze on the bottom of ponds. Usually very social, they become aggressive during the breeding season, protecting their nests in monogamous pairs. Females incubate the eggs and both parents care for the chicks for up to a year. They can reach speeds of 50 miles (80 km) an hour during long-distance migrations.
