Life habit:

Swan keeps a rare "lifelong companion system". When wintering in the south, both feeding and resting are paired. When the female swan lays eggs, the male swan is watching. When encountering enemy harm, it flapped its wings to meet the enemy and bravely struggled with each other. They not only help each other during the breeding season, but also pair in pairs at ordinary times. If one of them dies, the other one can indeed "celebrate the festival" and live alone for life.
