The Brazilian bird photography website, WikiAves, is an excellent example of how citizen science is adding to our knowledge of natural history. Bird photography has grown rapidly in Brazil in recent years. Photographers adding their photos to WikiAves enter the precise location of the record, building a highly accurate Brazilian distribution map for each species.

In the last few years, nine bird species have been photographed that are new to Rio de Janeiro (RJ) state, and these have now been added to the RJ state list (click on the link to view photos of the actual birds):
