Birds of REGUA

REGUA’s altitudinal range and variety of habitats gives rise to a huge diversity of birds. There are now 485 species of birds that have been confirmed at REGUA – more than at any other site in the Atlantic Forest and probably a greater number of species than at any site in Brazil outside of the Amazon region.
