Recipe For Energy Saving Unravelled In Migratory Birds

Thursday, May 15, 2008 - 09:14 in Physics & Chemistry

Pointed wings, together with carrying less weight per wing area and avoidance of high winds and atmospheric turbulence, save a bird lots of energy during migration. This is shown for the first time in free-flying wild birds. Researchers state that climate change might have a critical impact on small migrants' energy budgets if it causes higher winds and atmospheric instability as predicted.
