Question

Why had the birds flown to the south?​

Answer 1

Birds fly south in the winter in search of alternate food sources, and even though their summer home might be nicer, they return home in the spring when their usual food stocks are replenished

Answer 2

Answer:

Conditions are different in Northern Hemisphere countries like the United States and Canada. During the long days of the northern summer, birds have more hours to feed their young on the abundant insect population. But as the days shorten during autumn and food supplies become scarce, some birds migrate south.
