The Question: Swans are known to…
A Live in one place instead of migrate
B Never make sounds
C Mate for life
Mute swan pairs, like all swans, generally mate for life, and even grieve dead mates. Swan pairs share the same nest, remain monogamous, and share in the duties of raising cygnets.
Contrary to their name, mute swans make a variety of sounds although they are less noisy than other species of swans.
The correct answer is Mate for life.
