The term used for a group of birds is a "flock." This collective noun is commonly used to describe birds that are flying together or feeding in the same area. Different species of birds might have additional specific terms; for instance, a group of crows is often referred to as a "murder," and a group of flamingos can be called a "flamboyance." Flocks can vary greatly in size and may serve various functions, including protection from predators, increased foraging efficiency, and more effective communication among birds. Flocking behavior is a fascinating aspect of avian social structures.
