Orange-thighed Tree Frogs
Confined to tropical Northern Queensland rainforests, between Cooktown and Townsville, Orange-thighed Tree Frogs (Litoria xanthomera) live in the upper-canopy and descend to the ground only to breed. Emerging only after heavy rains, these beautiful tree frogs can be conveniently observed only four or five nights of the year.
Courting rituals are very noisy and may be heard for hundreds of metres through dense rainforest. Only males vocalize and it would seem to be the smaller males that out-compete for the affections of the females through their higher frequency, more energy-efficient and sustained serenading.
