Movement in amphibians provides evidence on migration, dispersal, homing activity, activity area, and site selection for reproduction, among others. So, research focused on animal movement is necessary in order to get to know and understand the species’ ecology. However, monitoring amphibians has always been a challenge, especially if the effectiveness of the tracking mode depends not only on the environment and habit but also on the morphology of the individuals. This also affects how the tracking device is attached to the individual.  Our goal in this study was to propose a less invasive attachment methodology for the spool-and-line method using Phyllomedusa burmeisteri as a model. We used our methodology on 15 individuals in the laboratory and in the field.  We noticed normal behavior of the individuals, and perceived that the device did not affect the motion of the individuals in the two study areas. We observed them for some time after their release and they managed to move around on the ground as well as to climb trees and branches. We propose the use of this technique for species with similar morphology and movement behavior.
