A group of swans is referred to as a bevvy, according to the Northern Prairie Wildlife Research Center of the United States Geological Center. If in flight, they may also be referred to as a wedge of swans.
A cob is the name for a male swan, and a pen is the name for a female swan. Cygnets are the name for young swans. Swans typically partner for life and defend one another. They frequently hold boisterous celebrations after the couple successfully repels an invader, according to How Stuff Works.
A parliament of owls, a murder of crows, a wake of buzzards, a charm of finches, a host of sparrows, and a mustering of storks are examples of other group names for common birds.
