It is found in tropical moist evergreen and deciduous forests, and coffee plantations with a natural canopy cover. It can be found in tree holes between two and four metres above ground level (Inger et al. 1984), and in the leaf-litter substrate. It may also be found in abandoned eucalyptus plantations close to forest. It presumably breeds by larval development, like other members of its genus, but it is not known whether or not it requires waterbodies for breeding.
Several individuals found on a building site, calling after late rain
Single Juvenile (8-10mm) found in leaf litter. Several days later one more mature specimen found. Both do not have visible spots.
This toad was found at about 10:00pm in a caliche tank (~50 ft long, ~20ft wide) surrounded by grassland. An explosive breeding event was occurring due to 2 inches of rain the night before. These toads formed a chorus, along with B. nebulifer, B. punctatus, and H. versicolor (with separate iNat observations). We saw 20-40 G. olivacea (many in amplexus), with similar sightings at nearby tanks (~.5 mile away). It was about 75° with ~10 mph wind.
