It's hard to believe that a bird that weighs only as much as a penny can fly 1,200 miles without stopping, but that’s what hummingbirds do each fall and spring. They winter in Mexico and Central America. Some even fly across the Gulf of Mexico, all open water. A trip that can take 18 to 24 hours. And, no, they don’t ride on the backs of geese. They don’t flock either, they are solo travelers.
