The Green-and-Black Fruiteater (Pipreola riefferii) is one of the emblematic species of the Andean cloud forest. Nicolas Mamani-Cabana, who worked as a field assistant on our research for three years, led the analysis and writing of this new paper published in Ornitologia Neotropical. Using radio tracking data that he helped collect, he analyzed the home range size and habitat associations of the species at our Peruvian field sites. The is the first study on movements and space use for the species. The paper is Open Access and published in Spanish.
