The weather forecast was indicating a promising herping night was coming up – a really hot day with a possibility of some humidity/storm in the evening. Jimmy wasn’t able to make this trip but I decided to go it alone to Canning Dam as it seemed like a good evening to maybe find a Death adder (Acanthophis antarcticus)! Their common name is the Common death adder but they are anything but – sometimes found in the valleys around the Canning dam area, they are a stealth predator.
I got out quite late after helping to get the kids to sleep and drove very slowly along McNess Drive looking for anything on the road – ever hopeful for herps! I parked up near the southern service entrance and walked through the gate. See here for my previous visit and map below. It looks like the picnic area is closed for refurbishment and its closed of an evening anyway.
It was pretty quiet and I was a little unnerved being on my own but wanted to make the best of a good night. It wasn’t far along the path that I came across this roadkilled snake – it is a Carpet python (Morelia spilota ssp. imbricata) – I needed help with the ID but the wonderful community on iNat were able to help – I thought it was a dugite at first – see here. Seems a shame as its a service road without public access so the staff should know better.
I then quickly saw my first gecko of the evening – a Barking gecko (Underwoodisaurus milii) but it didn’t pose for a photo. I had a few that were pretty skittish and this was the first two that I got an average photo of. They are beautifully marked and if provoked can put on quite a bluff show & vocalised hence their common name.

I saw a few more geckos and then headed back. I had another spot I wanted to try tonight that was close to the dam. I had read a paper where they had trapped mainland Quokka (Setonix brachyurus) which is one of my most wanted species. Unknown to most people about half of all quokkas live on Rottnest, the rest live in relative obscurity.

I headed a little way south and located the access track to the site. At this stage I won’t divulge anymore about the location. I drove in a little ways but was not comfortable as noone knew exactly where I was and it was an isolated spot. I had a quick spotlight from inside the car and will be back at some point with a buddy to explore more carefully. The habitat looked good with low wetland shrubs but it will be a challenge to spot any animals.
So all in all a nice evening to be out but with only 2 species of reptile and one of them dead. 🙂
