Because it's too far to walk.
Tell It Well
Ask for Science, Answer With Distance
The question appears to ask why birds migrate to warmer regions during winter. The answer shifts attention from why they go south to why they fly instead of traveling on foot. Ask the setup with genuine curiosity, as though expecting a lesson about seasons or migration. Pause long enough for that scientific expectation to form. Then give the answer as a completely practical observation. The literal response works because it is obvious, true enough, and unrelated to the explanation listeners anticipated.
