I decided to use the date of 1990 as a cut-off date. The Americas have a rich and varied avifauna. “It’s not just these highly threatened birds that we’re afraid are going to go on the endangered species list,” he said. Our mission is to build a global community around the freedom and beauty of birds in the wild as ambassadors for the natural ecosystems that they depend upon. However this pales in comparison to South America, which has more birds than any other continent, with an amazing 3389 species recorded here! I decided to find out.
