It is a fascinating phenomenon that homing pigeons always find their way
home. A doctoral student in biology at the University of Zurich has now
carried out experiments proving that pigeons have a spatial map and
thus possess cognitive capabilities. In unknown territories, they
recognize where they are in relation to their loft and are able to
choose their targets themselves.

Birds Outpace Climate Change to Avoid Extinction
A new study has shed light on the potential of birds to survive in the face of climate change.
In the analysis, based on more than fifty years' detailed study of a
population of great tits near Oxford, UK, a team of scientists were able
to make predictions about how the birds could cope with a changing
climate in the future.
They found that for small, short-lived birds like the great tit,
evolution can work fast enough for genetic adaptation to keep pace with a
changing environment. However, even for such fast-evolving species, evolution on its own is not enough.
