Although the bird-voiced treefrog is often found high in the trees, it can also sometimes be seen in lower vegetation, tree stumps, tree crevices, or occasionally on the ground (2) (3) (6). This species uses its limbs to wipe a layer of mucous over its head and body, which helps to prevent water loss when the frog is on high, exposed perches (3).
The bird-voiced treefrog is usually active at night (5) (6). Its diet consists of tree-dwelling invertebrates such as ants, beetles and their larvae, moths, caterpillars, leafhoppers and some spiders (3) (5) (6) (8), and it is likely to hunt by perching on vegetation and ambushing passing prey (6).
Around a month before the breeding season begins, male bird-voiced treefrogs start calling from the trees or from other woody vegetation over water (2) (3) (5) (6). This chorusing usually starts around dusk (2) (3) (6), but also sometimes takes place during the day (6). The male bird-voiced treefrog is territorial and will confront any other males that come too near to its perch. When it detects an intruder, the male gives a short, trilling chirp to warn it off, and if the intruder does not leave a fight may ensue (3).
The breeding season of the bird-voiced treefrog usually begins around March or April in the south of the species’ range and around May in the north (2) (3) (5), and it can last until September (3) (5). Mating begins with a female bird-voiced treefrog approaching a calling male and touching him. The male then grasps the female and the pair descends from the tree to the water below, with the female carrying the male. At the water’s surface, the female begins laying her eggs (2) (3) (6).
The female bird-voiced treefrog typically produces around 400 to 800 eggs per clutch (2) (6), with each clutch being laid in small clumps of up to 15 eggs each (3) (5). The eggs sink to the bottom or stick to vegetation in the water (2) (3) (5) (6). It is likely that the females of this species lay more than one clutch of eggs during the breeding season (2) (3). The bird-voiced treefrog’s eggs hatch after just 40 hours and the tadpoles take about a month to metamorphose into adults (2) (3) (5) (6). Newly metamorphosed bird-voiced treefrogs measure just over a centimetre in length (3) (5).
The bird-voiced treefrog is likely to reach maturity after one or two years (5), and females of this species have been known to live for up to four years (2). Potential predators of the adult bird-voiced treefrog may include birds, small mammals and snakes, but this amphibian’s camouflaging colouration, together with its habit of remaining hidden high in the trees, is likely to help protect it against predation (5) (6).
