Rondônia/Acre Popular Tour - August

Nineteen days deep in the western Brazilian Amazon, chasing birds that exist nowhere else on Earth. This tour traces the Aripuanã-Machado interfluvium, one of the planet's richest cradles of recently described species, where birds predicted by biogeography were later found exactly where science said they would be. From Porto Velho and the transition forests of Humaitá to the deep terra firme of Pousada PiraAçu and the endemic-rich Amazon Roosevelt, we work toward specialties like the Predicted Antwren, Western Striolated Puffbird, Rondonia Bushbird, and Rio Madeira Stipplethroat. We finish among the bamboo stands around Rio Branco, in Acre, home to fifty-plus bamboo specialists found in few other places. With a checklist topping 770 species, this is hardcore Amazonian birding for those drawn to endemics, mystery, and the frontier edge of ornithology: humid, immersive, and deeply rewarding.
