Did you know that a Black Swan was a symbol of what was impossible? In medieval times a Unicorn had more credibility than a Black Swan! Australian Swans, whether black or white are one of our most loved water birds. Swans are found across Australia and live in wetlands where they use their long elegant neck to reach deep into the water to feed on algae. With a wingspan measuring over 2 metres, swans live a nomadic life, migrating seasonally in response to the climate.
