Cygnus falconeri is an extinct, very large swan known from Middle Pleistocene-aged deposits from Malta and Sicily. Its dimensions are described as exceeding those of the living mute swan by one-third, [2] which would give a bill-to-tail length of about 190–210 cm (75–83 in) (based on 145–160 cm for C. olor [3]). By comparison to the bones ...

The legs are gray-pink ...
In comparison, swans that did not signal were only able to create a following 35% of the time. [10] In most cases, the whooper swan in the flock that makes the most movements (head bobs) is also the swan that initiates the flight of the flock – this initiator swan can be either male or female, but is more likely to be a parent than a cygnet.
