Warmer winters = more birds

22 02 2009

National Audubon has released a report saying that almost 60% of 305 species that overwinter in North America have shown a significant shift northwards in their use of wintering sites.  This seems to show a fairly direct correlation to long-term winter temperature increases. Have a look at the report (here) Must say that I wish this winter could have been a little warmer!!!!
