Data from: Subspecies-level distribution maps for birds of the amazon basin and adjacent areas

Available distribution datasets used to assess the range extantion of
biological species are often at a species-level taxonomy. Because
different taxonomy biases, many bird subspecies from the Neotropical
region may deserve full species status. We provide range polygons
for 3,990 subspecies of birds, representing 2,043 species from 65
families. All taxa are from the Amazon region, which includes the entire
Amazon basin, the east slope of tropical Andes, French Guiana, Suriname,
Guyana, south Venezuela (Bolivar and Amazonas departments), parts of the
Brazilian Cerrado, and the Araguaia-Tocantins basin. These new maps of
Amazonian bird subspecies distributions will improve and refine analyses
on biodiversity studies (e.g. macroecology, evolution, conservation), and
facilitate biogeographic, ecological, evolutionary, and conservation
research on birds in the most biologically diverse region in the world.
