Counting hawks with and without bands on their legs is

• direct observation

How is a clumped population distribution beneficial for prey animals?

• Being a member of a larger group provides protection for each individual from predators.

• Prey animals rely on each other to acquire food.

• Prey animals live in small family groups to raise young.

• Clumped population distributions ensure that at least one member of the population knows how to identify the seasonal migration route.
