Science answers question about crash

When US Airways Flight 1549 went down in the Hudson River, the culprit responsible for bringing the craft down were thought to be Canada Geese. Airports around the country have to deal with birds on runways but the question is whether the geese in this instance were resident birds or migrants. A report released today in the journal Frontiers in Ecology and the Environment shows the geese involved in the crash were, in fact, migrant birds. The technique used to determine this is pretty cool.
