Characters of color and morphometry in many groups of organisms vary with the geographic location of its population, resulting in intraspecific phenotypic variability. Although there are many known cases of intraspecific geographic variation, especially in acoustic characters in amazonian birds, there are few studies on the subject and much is speculated about the determinants of same. Starting addition, we tested whether there is variation in color and morphometry in three species of Amazonian birds: Gymnopithys salvini, Willisornis poecilinotus (Thamnophilidae) and Lepidothrix coronata (Pipridae) along the Purus-Madeira interfluve. We then test whether adaptive or stochastic mechanisms are associated with the organization of phenotypic pa...
