Birds such as the arctic tern migrate to seek consistent food supplies and favorable temperatures as the seasons change. Migration is an evolutionary adaptation to seasonal resource availability and reproductive needs. It's observed across various animal groups, including mammals and fish.

Step-by-step explanation:

Birds like the arctic tern migrate for several key reasons, the most significant of which are to find food and to access warmer climates. The long journey from the Arctic to Antarctica ensures that these birds can enjoy a consistent supply of nourishment and suitable living conditions as seasons change.
