Pigeons May Smell Their Way Home
A new paper provides evidence that the information pigeons use as a map is in fact available in the atmosphere: odors and winds allow them to find their way home.
The results are now published in Biogeosciences, an open access journal of the European Geosciences Union (EGU).
