A new mystery has been discovered in the migratory behavior of birds! Many songbirds travel long distances during their annual migrations, and it makes sense for them to do everything they can to conserve their energy during these journeys. Researchers have guessed that, for this reason, they might pick an altitude with favorable winds and stick with it rather than climbing and descending repeatedly, but there has been little data to back this up.
