What is a group of swans called?

a "flock" or a "herd" of swans. Swans are social birds, and they often form large groups during their migrations. During non-migratory times, however, swans tend to stay with a mate or in smaller family groups. In a flock or herd of swans, males are generally larger and more aggressive than females, but both sexes are highly territorial. Swans are also known for their synchronized swimming and vocalization, which they use to communicate with each other. Overall, a group of swans is a majestic and fascinating sight, particularly when they are flying in formation or floating gracefully on a calm body of water.
