Bird responses to climate change are just beginning, but a lot is already
there to see. See my earlier reply to Dennis about tanagers. Also, below is
a link to my blog post about southern species expanding north. This also
includes the Audubon projection maps, which are pretty accurate and already
happening for many non-migratory species.

There are also species declining in the south (especially in deserts).
It seems that, so far, many non-migratory species and short-distance
migrants are shifting ranges quickly, especially if they are flexible wrt
food sources and not dependent on a single food source (e.g. oaks, which
aren't really migrating). Many long-distance migrants, however, don't seem
to be really changing their behavior that much. They are perhaps quite
hard-wired.
