Facts about this animal
A large swan, but somewhat smaller than the mute and the trumpeter swan. It has a total length of 140-160 cm and a wingspan of 205-235cm. The average weight of males of the nominate subspecies is 10.8 kg, of females 8.1 kg. Whistling (C. c. columbianus), Bewick’s (C. c. bewickii), and Jankowski’s (C. c. jankowskii) swans are clearly smaller.
The female lays 3 to 6 white eggs, in a very large nest near water. The eggs are incubated typically for 31-32 days, in the smaller subspecies 29-32 days, exclusively by the female.
Did you know?
that whooper swans form pair bonds when they are three or four years old? The pair stays together throughout the year, moving together in migratory populations. Whoopers are assumed to mate for life, but some individuals do switch mates over their lifetimes.
