Green Tree Frog (Litoria caerulea)


A large species and possibly the most well known native frog found throughout the Sydney region. Green Tree Frogs often inhabit mailboxes, meter boxes, bathrooms and toilet blocks in the warmer months of the year, characterised by their large eyes and ‘friendly’ smile. The upper surface is dark olive to bright green in colour and may have a scattering of white spots across the back and sides.

Large toe discs and a yellowish to white underbelly allows for easy identification.
Calling often occurs in summer immediately after rain from hollow branches nearby water bodies or drainpipes and is quite loud due to the echoing surrounds.

Unfortunately, populations of the Green Tree Frog have declined noticeably in many suburbs throughout Ku-ring-gai and may have completely disappeared. Historical records exist from St Ives, Gordon and Turramurra, but it is now thought to be locally extinct. This may be due to the filling in of old ditches and temporary ponds as well as the removal of old material and shelters (habitat) from backyards.
