Frank E. Rheindt, researcher in the department of biological sciences at the National University of Singapore, traveled to the Wallacea Islands on his own to watch birds. During that 2009 expedition, the scientist discovered new birds that he did not know about. Four years later, he left with his team to collect all the information and DNA samples in just six weeks. The results that are published this Thursday in the magazine Science show that, on the Wallacea Islands of Indonesia (Taliabu, Pegen and Togian), ten unique and until now unknown species fly over mountains of up to 1,400 meters that explorers of other centuries never reached.
