What are the advantages and disadvantages of flocking?

Flocking offers several advantages, such as improved safety and efficiency through collective movement, which can enhance foraging and predator avoidance among animals. It also fosters social interactions and strengthens group cohesion. However, disadvantages include the potential for increased competition for resources and susceptibility to disease spread within dense groups. Additionally, flocking can make individuals more conspicuous to predators, potentially increasing their risk of being targeted.
