Why do birds migrate?

Ilyaperminov 7 февр. 2022 г., 17:25:01

If all birds were to stay in the same tropical regions year - round food would become scarce and breeding would be less successful.

But as food sources are regenerating in the north each spring, millions of birds to those areas, to take advantage of abundance.
