It has been postulated that a special part of migratory birds' brains contain a magnetic material which keeps track of the bird's alignment with the magnetic field of the Earth.
They fly.
humming birds migrate the same way the other birds do. Like when it is cold in north they fly south and when it is cold in the south they fly north.
To answer this question we need to know south or north of what.
love birds miograte down south, if you know what i mean ;]
Cause in the North it can get really cold and birds don't mostly survive in the cold so they fly south were it's warmer or hotter.
By banding the bird's leg with round metal tags, scientists have learned the migratory patterns of most species of birds. There are numbers on the tags so the scientists know where they started their journey and other scientists record these tag numbers in the south and vice versa when the birds fly north.
It depends entirely upon the species but MOST migratory northern hemisphere birds migrate south, and MOST migratory southern hemisphere birds migrate north. But that is a huge over-simplification.
Birds that migrate generally do so on a North-South axis. Many birds that live on the Asian continent migrate throughout Asia. It would be unlikely, or "accidental," for birds from, for example, North America, to migrate to Asia.
When birds fly south for winter each year, this is known as "migration." The birds fly south to live in a warmer climate, and in the spring they fly north again when the weather changes.
