Rain this past week has been coming down in bucket loads and frogs have been calling along all the creeks in the Jarrah forest. An area I often go to, has a creek running over a flat sheet of granite with rocks scattered over it. There seemed to be at least two frogs under every large rock, many with eggs. I could hear other species, but all the frogs I found under the rocks were Quacking Frogs (Crinia georgiana).
For a single species, there seems to be so much variation in just an area of 10 metres. Normally you can tell the species by it's red or gold eyelids and red groin, but some didn't even have that.
