Birds of Brazil (click maps to enlarge)
Maps of bird diversity include the total species richness, species endemic to Brazil, globally small-ranged species, and threatened species as defined by the IUCN. Species considered small-ranged are those with a geographic range size smaller than the global median (i.e., the 50% of species with the smallest ranges). Maps are derived from digital distribution maps for all the world’s birds in BirdLife International and NatureServe (2014).
All maps have been generated at a spatial resolution of 10×10km and use the Eckert IV equal-area projection. Maps represent native, extant species only. Tables of the species included are available for download here. Biodiversity maps for Brazil were first published in the article below.
