A diverse array of animals use a multidimensional acoustic space as primary source communication, especially in habitats where other signals are limited. However, complex habitats, species must contend with co-occurring to send their message backdrop ambient noise. This is exacerbated closely related that occur sympatry, and we do not know how learn vocalization have repertoires partition space. In this study, studied four group birds, the drongos, tropical evergreen forest South Asia. We made field vocal recordings well estimated song perch heights from December 2018-April 2019. Using ordination methods like PCA LDA, find wide overlap sympatric drongos. We, however, drongos segregate vertically. hypothesize owing ability mimic species, which increases signal breadth. To space, potentially vocalize different heights. Our study broadens our understanding vocally birds may
