Examine the graph below.
Research indicates that goshawk predation is much less effective when prey species, like wood pigeons, are in large flocks. This is true because
A)large flocks are just temporary aggregations of several small flocks.
B)large prey flocks may be able to better provide advance warning of predators.
C)predatory birds are generally afraid of large prey flocks and will not attack birds in them.
D)small flocks are more likely to have parasites that change behaviors, making the prey more susceptible to predation.

Quizplus · Accepted Answer

Research has shown that prey species in large flocks are less vulnerable to goshawk predation because they are more likely to be able to provide advance warning of approaching predators. In addition, large flocks may also make it more difficult for predators to lock onto a single target, reducing the likelihood of successful attacks. The other options are not supported by research or evidence.
