Many species of birds are behaviorally adapted to migrate from one area to another as the seasons change. Often, this migration involves the birds flying north toward the Arctic during the summer and returning south during the winter. These birds have most likely adapted their behavior of migration because it allows them to
a. burn excess energy during times when increased food is available
b. find food more easily during stressful environmental conditions
c. decrease the number of individuals killed by predatory birds.
d. increase their reproductive success by leaving offspring in many areas.
find food more easily during stressful environmental conditions

The correct answer to this question is b. find food more easily during stressful environmental conditions.
Birds that migrate have adapted their behavior of long-distance movement because it allows them to find food more easily during stressful environmental conditions. This is particularly true in the Arctic, where food availability is limited during the winter months. By migrating south during this time, the birds can find areas with more abundant food resources, increasing their chances of survival.
To arrive at this answer, it is important to understand the concept of migration and the reasons behind it. Migration is a strategic behavior exhibited by many bird species to cope with changes in environmental conditions, particularly those related to food availability. By understanding the ecological pressures and constraints faced by birds in different seasons and locations, we can deduce that the primary benefit of migration is the ability to find food more easily during stressful environmental conditions.
Another important concept to consider is the pattern of bird migration. Many bird species fly north toward the Arctic during the summer to take advantage of increased food availability in the form of insects, breeding opportunities, and longer daylight hours. They then migrate south during the winter when resources become scarce in the Arctic. This pattern suggests that finding food is a key motivating factor for bird migration.
To summarize, when answering this question, it is crucial to consider the ecological pressures and constraints faced by migratory birds, the pattern of bird migration, and the main benefits of this behavior. Based on this knowledge, the correct answer is b. find food more easily during stressful environmental conditions.
