I`ve heard that some birds are capable of prolonged flight and spend many
days in the air.  I can believe this of birds like albatrosses that are adapted
to gliding.  But I`ve heard also that some swallows will spend months in the
air without landing.  This sounds a little far fetched to me.

Could anyone confirm or refute these stories and point me at a good, short
review of the subject?
