Anurans that congregate to breed alongside streams are good models to answer questions about homing decisions. Specifically, they allow us to document if individuals prefer to return to their original calling site and chorus when there are closer alternative choruses from which they can call and mate. We performed a capture-recapture experiment alongside a stream with Espadarana prosoblepon (Centrolenidae) in the Central Andes of Colombia. We translocated 27 males from their original calling site and chorus to sites located either between two equidistant choruses (original and alternative choruses) or within an alternative chorus. Eighteen translocated males returned to their original calling site and chorus, three males moved or stayed in alternative choruses, and six males were never recaptured. We recorded mating in males that exhibit homing as well in those that moved toward alternative choruses. Given that homing is costly and risky for individuals, and Espadarana prosoblepon males can mate whether they call from their original chorus or from an alternative chorus, our results suggest that homing motivation is in part influenced by benefits associated with a familiar environment.
