BirdPhotos.com has just addded interactive Species Range Maps for over 3000 species. Our data comes from Infonatura, and represents mostly North, Central and South American birds. Photos in the gallery have a 'Range Map' link at the top, and you can see maps for species not represented in the Gallery by clicking on "See Complete List" at the top of most albums. Or by using Checklists or the new "Search All Species" option on the search page.
Recently we have tried to describe with text splits that have occured in existing range maps, as seen here.
Also included are Range Maps from BirdLife International, the most important bird conservation organization. They are provided for endangered species at the bottom of the photo page.
