Final answer:
Bird species that form large flocks exhibit a clumped dispersion pattern, which is a social behavior that offers various advantages such as increased foraging efficiency and protection.
Step-by-step explanation:
The dispersion pattern that describes the behavior of birds forming large flocks is clumped distribution. Unlike uniform distribution where individuals are evenly spaced, or random distribution where there is no predictable pattern, clumped distribution occurs when individuals are grouped together. This pattern is common in species that exhibit social behavior, such as birds flying in flocks or animals that move in herds. This type of arrangement may be advantageous for finding food, protection from predators, or for breeding purposes.
Many species of birds form large flocks, and this behavior is an example of clumped distribution. Clumped dispersion is characterized by individuals being clustered together in groups, which is seen in animals that live in social groups like birds that form flocks. This pattern allows for increased social interactions, protection from predators, and efficient foraging.
