Are swallows migratory birds?

Swallow is a migratory bird. Every March, they fly from the south, as if they all flew back from the south overnight. Many swallows fly in the sky and stop on the wires. Then they will choose a family's house to build a nest, and then lay eggs, hatch eggs and raise young.

After a busy summer, the weather turned cold in late autumn, as if the swallows disappeared overnight, and they flew to the warm south for the winter.

Swallow's living habits:

Swallow is a migratory bird. Its life habit is to fly to the south in late autumn and fly back to the north in spring. Swallows are spiritual birds. No matter how far they fly, they can find their own homes and rebuild their nests. Generally, swallows breed in the north, and at least two nests of small swallows must be bred to fly alone.

Swallows spend the winter in the south, not in the south of China, but in Southeast Asia and Australia. One reason why they spend the winter in the south is that the winter in the north is too cold for swallows to bear the low temperature, while the winter in the south is warmer.

Suitable for the life of swallows. The other is because the swallow's food is insects, but there are few insects in the north in winter, and the food source is not enough, while there is plenty of food in the warm places in the south.
