Distribution Maps

About the maps:




Distribution maps are based on the predicted occupancy at roughly 130,000 grid points using data from eBird and associations with land cover and other key environmental variables. Brighter areas indicate a higher probability of occurrence.


For species with very small ranges or associated with wetlands, we generated maps using the frequency of each species reported on eBird checklists, which provide coarser data and summarized occupancy within 20 sq km blocks.

Western Forest 



Mexican Pine-Oak Forest


Boreal Forest
