if anyone is still wondering what crazy bird would fly across the atlantic, I found a map of common bird flyways.

there are studies showing that the migratory birds are passing the flu from one spot on their migratory patterns to other spots farther along in their migration (china to siberia). what interests me most is the large area of Alaska where the east asia flyway and the mississippi flyway cross.
