Recipe For Energy Saving Unravelled In Migratory Birds
ScienceDaily (May 13, 2008) — Pointed wings together with carrying
less weight per wing area and avoidance of high winds and atmospheric  
turbulence save a bird loads of energy during migration. This has been  
shown for the first time in free-flying wild birds by researchers at
Princeton University, the University of Montana, and the German Max
Planck Institute for Ornithology. They state that climate change might  
have a critical impact on small migrants' energy budgets if it causes  
higher winds and atmospheric instability as predicted.
