About the Maps
Note: Range is depicted for the New World only; some species occur in the Old World as well. Range at sea is not shown. The scale of the maps may cause narrow coastal ranges or ranges on small islands not to appear. Vagrant occurrences are not depicted. For migratory birds, some individuals occur outside of the passage migrant range depicted.
