Searching for Quokkas at Canning dam…

I am currently behind on my posts – so this is actually from January!

I decided to continue my hunt for mainland Quokka’s (Setonix brachyurus) in the greater Perth region. Despite what most people are aware of – they don’t only live on Rottnest Island where they are easy to find, they can also be found on the mainland, but are much rarer and cryptic. I have looked in the Canning dam area before as I found a paper and it listed
Midgegoroo National Park as one of the trapping sites where they had caught animals. My brother was down from Port Hedland and he was keen to join me as well for a late night spotlight.

We started off looking for herps in the Canning Dam proper – parking near the gate and walking up the road looking for eyeshine. It took some time walking around before we found our first Barking gecko (Underwoodisaurus milii).

We then headed further down towards Albany Hwy to my Quokka spot – I was pleased to have company as it’s an isolated spot. On the way we found a freshly road-killed Carpet python (Morelia spilota) – such a shame. There must be a few around as this is the second dead specimen I have found and my friend Jimmy found one on a previous trip.

We drove down a gravel track and parked as close as to the location as we could. I have had information from a scientist that Quokka’s are found in West facing streams in riparian vegetation – which means it’s tough to get through. We spotted a couple of kangaroos in the distance and heard the yipping of a fox but didn’t see any Quokka – strike 2!

We found some scat that I can’t say is 100% Quokka but the size seems right and it was cubic and slightly flattened.

We also found some diggings and then scat which I believe is feral pig.

An interesting night in the correct habitat for Quokka’s but I think if any were around they would have disappeared as we came crashing through the thick scrub! Another observation was this cricket that I am hoping to get a proper ID on iNaturalist – currently thought to be one of the Raspy cricket family (Gryllacrididae).

We had a good night – perhaps a hint of a Quokka but I need to keep looking for a confirmed sighting and photo!

Herping at Canning Dam

My naturalist buddy Jimmy and I planned to come out herping just before Christmas on the really hot 38°C day.  Hot days mean warm nights and this can mean the herps are more active into the evening.  It was also moonless so we hoped that would help us see more.

We headed up to Canning Dam – our primary target Southern Death Adder – Jimmy has been looking for them for a number of years with no luck as they are really hard to find.  They tend to sit in leaf litter motionless just waiting for an unlucky prey item to come past – the warm nights can bring them onto the road to be found.  Jimmy had checked it out the night before with no luck but had found a roadkilled one a couple of weeks before – so we know we are in the right spot.

We brought our bikes as the Water Corporation block off access at night – this allowed us to cover plenty of ground.

Our first wildlife was an inquisitive Tawny Frogmouth that checked us out.

We then found our first of what was to be many – Barking Gecko.  They get their name from their behaviour when threatened – they arch their backss and bark quite loudly.  They have real character and are beautifully marked.

Barking Gecko

Just across the road from the Barking Gecko, Jimmy spotted another gecko – which after a closer inspection was a Clawless Gecko – Australia’s smallest species.  This one was only 4-5cms long and beautifully coloured.

{edit  Jan 2018 – I have since had it identified by Ryan Ellis a WA Museum research assistant – that this is a Speckled stone gecko (Diplodactylus lateroides) – recently described in 2013 in this paper – Thanks Ryan!}

We found plenty more Barking Gecko but they weren’t that obliging for photos!  They are the biggest geckos that I have seen.

We looked carefully on a granite outcrop where Jimmy had seen a good sized Carpet Python the night before – sadly not there tonight.  Our night was snakeless – shame…

We did hear a few White-striped Freetail Bats – they are audible with the human ear and often heard.

Towards the end of out travels we crossed over the river that comes from the dam and there were plenty of frogs – Motorbike, Slender Tree and probably a Moaning Frog.

All in all a great night with two new geckos for me but a distinct lack of snakes – well we will just have to do another trip!

On the way home I took some shots of a roadkilled 2D rabbit and bobtail.

Snakes on a ….

My brother sent me an email this week that I thought was worth sharing..

I have titled it Snakes on a plane server!

Our servers at work have been a little temperamental recently.

Ron thinks he’s found the problem.

python

From my little bit of research it is a Stimson’s Python.

So Ron and I carefully used a broom and a bucket to catch him and released him into the bush-land next door.

It was actually a south-western carpet python (Morelia spilota imbricata) and its a pretty strange spot for one to be in industrial Welshpool.  Hopefully it has a good life.. and turns from its life of criminal server damage!
