Cygnus atratus

 

 

General Information

The black swan belongs to the class of birds. It is found in Tasmania, New Zealand, and Australia. It has a flattened bill that is crimson in color and has a pinkish tip. The black swan is one of the smallest swans, but it is about four feet in length and weighs 9-11 pounds. It has two white areas: a ring surrounding its bill and an area on the tips of its wings. Long pointed wings with water -repellent feathers are very important to the black swan. It also has short legs with webbed feet. Males are usually larger and longer necked. The female usually lays 4-6 whitish eggs, which both parents keep warm. Eggs must be warmed 30-35 days before they hatch.

Interesting Facts

The black swan is the emblem of Western Australia. Before swans and swan eggs were protected, their eggs were used as a chocolate malt in Australia. This swan needs 40-50 yards for flight takeoff and can fly up to 1000 feet in the sky. The black swan does have a very musical voice, but it doesn't carry very far.

 

Niche / Habitat

The black swan lives on shores and in lakes. It can also live on land for periods of time. The black swan belongs to the freshwater biome. It eats grasses, underwater plants, and small fish.

 

 

 

Adaptations

Some adaptations the black swan has involve its neck, feet, and beak. The neck of the swan allows it to reach up to three feet underwater. Its feet allow it to live both in water and on land. Eating plants is very important to the black swan. Its special beak allows it to break and pull plants from the ground. Migration can vary depending on where the swan lives.

Environmental Change

 

There are a few environmental changes that have harmed the black swan. At Lake Ellesmere, New Zealand, some 60,000-80,000 swans were badly affected by a storm in 1968. The black swan has also been attacked by aspergillosis fumigatus, a fungi disease affecting the respiratory system. In the 1800's, farmers were hunting for the black swan's meat, and when their population decreased, they became protected in Australia.
