Habitat and Ecology

This species inhabits primary humid montane forest with high abundance of arboreal ferns, bromeliads and other epiphytes. Potentially flooded flat surfaces are almost inexistent but there are some small streams. Rhinella tacana is a nocturnal species that can be found active on leaves of bushes or on the trunk of trees from 1–4 m height. It climbs vertical trunks covered by moss. The adult female presents convoluted oviducts and small white ova. The call, tadpole and reproductive mode are unknown. Other anuran species that occur in the area are Atelopus tricolor, Ameerega boliviana, Hyalinobatrachium bergeri, Hyloscirtus armatus, Hypsiboas balzani, Pristimantis danae and P. madidi (Padial et al., 2006).
