For the birders out there:
Be sure to check out the interactive maps on the Boreal Songbird Initiative:
Migration Maps
http://www.borealbirds.org/birdguide/mig_map_main.shtml
Cities (as in Towns not CITES):
http://www.borealbirds.org/birdguide/map_main.shtml
This is excellent as you can select an American city and the map shows the
birds that migrate from the Canadian boreal forest.
