Whistling Tree-frog or Verreaux’s Tree-frog has two sub-species, Whistling Tree-frog (Litoria verreauxii verreauxii), which is widespread and common across eastern Australia, and Alpine Tree-frog (L. v. alpina), which has a very restricted range and has suffered massive declines; it is currently listed as critically endangered. Both reach a maximum size of 35mm.
Whistling Tree-frog (L. v. verreauxii) is light brown to red brown above, with an often indistinct, broad, darker patch starting between the eyes and continuing over the back. A dark band starting at the nostril runs across the eye and down to the shoulder, underlined by a white line starting at the mouth. The thighs and backs of the legs are red with small black spots, with some larger black spots present on the fronts of the thighs.
Alpine Tree-frog (L. v. alpina) is mostly green on the dorsal surface with two brown bands running parallel to each other down the back. These bands start at the eye and are separated by a narrow band of green. The thighs and backs of the legs are the same as above. The belly of both subspecies is white. <>Whistling Tree-frog inhabits swamps, dam impoundments, and creeks in woodland, farmland, forest and cleared land. Males call from pond-side vegetation or from the ground all year round, but calling intensifies during autumn and spring and after rain. As its name implies, this frog makes a whistling noise. The alpine tree frog inhabits alpine ponds and pools of creeks in moorland, alpine forest and partly cleared land. Males have a similar call as above and call from beside the breeding sites during spring and summer. Green coloured forms of L. v. verreauxii (see image) have been sited at Garuwanga near Nimmitabel.
Chytrid fungus is believed to be partly responsible for the decline of the alpine subspecies. (Wikipedia).
