Seasonal bird migrations could be cited as an example of?
A. Clumped Dispersion- They are situated in large numbers in a concentrated part of their habitat. Migrating birds are usually in groups, and tend to stay that way. Even though there could be millions of acres of their habitat for them to spread out in, they'll never be evenly (uniformly) disbursed. They stay close together for safety, food and mating reasons.
