Migration

Operation Migration is helping restore the whooping-crane population by an unusual strategy: using human pilots in ultralight planes to lead the cranes on their annual migration.


There are only two migratory wild flocks, one with about 200 birds and one with about 20. They are flying from Canada to Texas and from Wisconsin to Florida, respectively. (You don't think that cranes are Republicans, do you?)
