Habitat and Ecology [top]

Habitat and Ecology:	This is an arboreal, canopy-dwelling forest and forest-edge species. It occurs in a number of habitat types from savannahs and other open habitats to both dry and moist forests. It can be found in disturbed habitats, animals may even be found within human dwellings. It can live within second growth forest and plantations. This species breeds at the beginning of the rainy season, with males calling at night while floating in large temporary pools or intermittent streams. The floating egg clutches are laid in the water where the tadpoles also develop.
Systems:	Terrestrial; Freshwater
