Black Swan

Appearance:
The black swan has dark body plumage with white feather tips on its wings. The bill is a deep orange-red with a white band near the tip. This species has bright red eyes.

Size:
Length: 3.5-4.5 feet
Wingspan: 5-6.5 feet
Weight: 13-20 pounds

Behavior:
Black swans are the least territorial of the swan species. Though they usually have their own territory, they will flock when food becomes scarce. Black swans feed at dusk and fly at night, calling to each other to ensure they remain together. Their first line of defense against potential predators are their large wings, which they flap loudly to scare away other animals.

Reproduction:
Breeding season for black swans takes place from May to September annually. Individuals will find a mate and remain monogamous for life. The mated pair will build a nest in which five to six eggs are laid. The incubation period for these eggs is 35-48 days. After hatching, black swans reach sexual maturity between one to three years of age.

Habitat/Range:
Mated pairs establish territories of wetlands, ranging from fresh to salt water, throughout Australia. They prefer regions where aquatic plants are plentiful.

Diet:
Black swans primarily eat aquatic plants and algae. They sometimes come on land to forage for grasses.
