The whistling tree frog (''Litoria verreauxii''), or Verreaux's tree frog, is a species of frog found in Australia. It has been divided into two subspecies, the nominate Verreaux's tree frog (''L. v. verreauxii'') and the Verreaux's alpine tree frog (''L. v. alpina''). The alpine tree frog is restricted to the southern alps of
''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. Both reach a maximum size of about .

Conservation status
''Litoria verreauxii verreauxii'' is widespread and common across eastern Australia. ''L. v. alpina'', though, has a very restricted range and has suffered significant declines population; it is currently listed as endangered.Evolution

Description
''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.
''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. Both reach a maximum size of about .
Ecology and behaviour
Verreaux's 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 thebreeding

It is kept as a pet; in Australia and New Zealand, this animal may be kept in captivity with the appropriate permit.References
