Black Swan

Native to Australia and Tasmania, Black Swans are easily recognizable due to their jet black feathers lined with white and their bright red eyes and bills. Males are called cobs and are larger than females, which are called pens. A group of swans is called a bank or a wedge and baby swans are called cygnets. Black swans are monogamous and usually take a mate for life, but have also been known to sometimes mate in colonies. These swans are territorial (but the least territorial of all swan species) and usually stay in solitary pairs. Their nests can be large mounds up to 3 feet high and they can have anywhere from 4 to 12 eggs in a clutch. The eggs are laid one to two days apart from each other and then the incubation period is 35-48 days after the full clutch is laid, that way the eggs all hatch around the same time. Both the male and female swan incubate the eggs.
