Do the Birds migrate from East to west or North to West (from one country to another)?

Which is the Bird that could fly the farthest, non-stop?
Answers:
Yes, there are birds that migrate from Europe to North America and/or Canada. During the West Nile Virus scare, it was a huge concern that the migratory birds from Europe would bring the virus with them to non infected areas.
As far as birds that can fly the farthest non-stop, I can't say. There isn't a bird that I know of that can migrate non-stop without eating. Mainly the birds that cross the ocean are water birds who will stop to eat on their way. There are birds that will spend most of their lives in the air without landing such as the Albatross and the Swift.
