How bird migration evolved


Just as many Michiganders fly south in the winter, a new study found that is also what the birds decided to do. It was previously thought that tropical birds made their way north to find breeding grounds. Now a new study has revealed that northern birds first began to travel south for the winter, perhaps to find food. Eventually some even lost their urge to migrate back to the north and just remained in the tropics year-round.

Scientists have developed a new method to reveal the ancestral ranges of New World birds, and discovered that bird migration in the Americas evolved in species that resided in North America. Their work also offers evidence that many tropical bird species descended from migratory ancestors that lost migration. So the birds that fly north each spring are just returning home.
