There's been somewhat of a breakthrough by researchers at Cornell University's lab of ornithology who have a better idea of just how small songbirds migrate.   Scientists have known for over a century that waterfowl like geese and ducks tend to follow the same, narrow migration paths.    But after combing through years of crowd-sourcing data, scientists can now say the travel habits of tiny land-based birds follow less-defined flyways, and instead depend on wind patterns.  LaSorte says until now, the migration of small songbirds was mostly speculation.
