Whooper swans owe their name to their multitude of calls. So you can hear a "gigigi" to welcome fellow species and a "ga" or "go" during resting periods. The sounds od every individual are unique. It is easy tell them apart looking at the beak of the white swan. While it has a reddish beak with black wax skin the whooper swan has a black beak with yellow skin.
