Most birds migrate in the winter or fall because it is too cold for them. If they did not migrate, they could freeze! When birds migrate they fly and fly until they reach a place that is not so cold.
like any animals or birds if the lemming did not migrate then it would probably freeze to death unless the weather was extremely hot or cold in some cases which is very rare if all the summer or winter has been the opposite weather
they would die
we would die
You would die
you would blow up
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.
what would happen if the 8th amendment didn't exist
we have freedom
you die
?
Nothing would happen. You either believe in them or you don't!
It'd die.
