Juvenile Magnificent Frigatebird

Magnificent frigatebirds are birds of the open ocean. Although their nests are on coastal areas, these birds are in flight for a majority of the time. Often they fly long distances over open water far from land. Their wings are so large that flying is nearly effortless. They take advantage of updrafts and can glide for long distances without beating their wings. They use their long, forked tails for maneuvering. They are one of the only birds with the ability to ride out a hurricane's strong winds.

Frigatebirds never land on water, and always take their food items in flight. They spend days and nights on the wing, with an average ground speed of 10 km/h (6.2 mph), covering up to 223 km (139 mi) before landing.

(The only other bird known to spend days and nights on the wing is the common swift).
