Migrating birds will not take off into a storm. But, they can’t always know what lies before them. One of the gravest dangers before a flight of night migrants is the sudden storm. Not wanting to fly into the eye of a storm, the birds simply let-down or what we know of: a “fallout”.
While the migration of geese is conspicuous, the flight of many other birds takes place largely unseen, because many birds travel by night. Periodically, however, we get a glimpse into just how big those numbers are when a sudden storm or low overcast forces the birds down. Bird-watchers refer to these events as "fallout".
