This Saturday’s night walk was very well attended (17 people) and provided lots to see, especially in terms of fluorescent wildlife. We started off the walk with a rousing solo vocal performance from one of my resident orange-thighed tree frogs, with distant vocal back-up from numerous nursery frogs and one or two robust whistling frogs.

As we started our walk around Lennox Crescent the glow worms formed an unmistakeable series of “fairy lights” along one of the exposed earth banks beside the road.

Brilliantly coloured fluorescent lichens were the most common organisms visible with our UV torches, with an amazing diversity of colours shapes and patterns on trees, logs and even mailboxes!

Along the track to Witts Lookout we also saw some great examples of the sinouus blue fluorescing supplejack vines.

For the first time we also found two different animals exhibiting fluorescence: a small snail and a worm (not photographed).

The normal array of small nocturnal spiders, crickets, millepedes and moths were also seen. I also had a fleeting glimpse of what was probably a bandicoot hopping across the track as we returned along the Witts lookout track.

There seems to be a consistent difference in fluorescent and luminous flora between the H-Track and Witts Lookout track. Witts track had very few logs covered with the fluorescent liverwort (Bazzania vitatta) although it is very common on the much of the Lennox Crescent and back sides of the H-Track. Also there seem to be fewer luminous mushrooms. One of the group pointed out that the micro-climate on the H-track is more sheltered and humid compared to the Witt’s lookout track, which follows an somewhat exposed ridgeline that slopes steeply down to the coast. This seems a very plausible explanation. A few of us finished the night’s walk by going down the start of the H-track in order to see the large log that consistently puts on a gorgeous fluorescent display. It did not disappoint us!

It was wet and cold but good weather for frogs and snails

The inclement weather probably accounted for the fact that Juanita and I were on our own last Saturday night and even we decided to take a shortened walk via Lennox Cr to McClelland’s lookout. However, the rain certainly didn’t discourage two groups of nocturnal animals that love moist weather. The robust whistling frog (Austrochaperina robusta) was calling continuously all around Lennox Cr.

This small frog is seldom seen (I have never seen one!) but is one of the most familiar nighttime sounds around Paluma whenever the weather is wet. We got within half a meter of several calling individuals but they were very well hidden. Another common frog around Paluma that is very noisy but highly secretive is the southern ornate nursery frog (Cophixalus ornatus). It too could be heard during the walk but much less frequently and as usual we did not see one (although I did spot one once in my garden last year). Have a listen to the calls below and see if they sound familiar.

Although it was not calling on Saturday night we did spot our resident yellow-thighed tree frog hanging out near our concrete wash-tub pond at home at the end of the walk.

The other group of animals that reliably comes out at night, especially when it’s wet, is land snails. Australia has a very rich diversity of endemic land snails ranging from ones with full-sized shells to semi-slugs with a very small vestigial shell that they cannot retreat into and is normally covered by a layer of tissue. We saw two snail species and my best guess is that they were both locally endemic snails named after our village!

Using UV torches has become de rigueur on our night walks and while we did not come across any of the striking fluorescent blue liverworts that we often see on the H-Track, a couple of trees had strikingly fluorescent lichens. Juanita took several pictures and then returned on Sunday morning to get comparative daytime shots of the same patches. The difference is amazing.

We will have another night walk in around 2 months time and would love some company if you are up in Paluma and feel like a night-time stroll. We always seem to find something interesting!

This is a reminder that the next Paluma After Dark walk will be this Saturday, August 27th. We will meet at 6:30pm at Potters Park opposite 27 Lennox Cr. It could be a bit chilly and there is a small chance of rain, so bring a jacket/raincoat as well as a torch. I will have spare UV torches for anyone who is interested in looking for fluorescent liverworts or lichen. Hopefully, we will see some bandicoots and pademelons along the track.

The recent “Paluma After Dark” night walk took place last Saturday night at Don Battersby’s place on Hussey Road. The walk was well attended, with 7 locals and 5 visitors. A quick tour of Don’s property revealed a few interesting fluorescing lichens and plants and several tiny prowling wolf spiders whose eyeshine seemed disproportionately bright for their tiny size.

Once into the forest behind Don’s block we were given a full tour of the track to Ethel Creek and back via Hussey Road.

Using the various UV torches on hand, we saw several glowing supplejack vines, many brilliant red tree seedlings and several spiders, including the common jungle huntsman. Several mossy logs also had a sprinkling of fluorescent bryophytes similar to ones we have previously found on the H-Track.A couple of us also heard and caught a fleeting glimpse of a native rat, but not enough to identify the species.

On the way back to Don’s, walking along Hussey road with heavy feet and flagging attention, Juanita spotted some eyeshine in a tree beside the road. Closer inspection showed it to be a sugar glider (Petaurus breviceps). Although about 5m up and partly obscured by branches it was nevertheless easy to make out the facial markings and skin folds between fore and rear legs that provide for fairly positive identification. It was a great ending to the evening and is the first arboreal mammal that many of us have seen in Paluma. As an added bonus, one of several leaf-tailed geckos (Saltuarius cornutus) living in Don’s shed came out to bid us goodbye as we prepared to leave. Below are pictures (not taken that night) that illustrate these last two species.

Many thanks to Don, for his enthusiasm and stamina in leading this walk.

Our next walk will be in August and will be advertised on the web.

The next scheduled Paluma After Dark evening walk will be this Saturday evening at 6:30pm. This time we will be exploring Don Battersby’s property and nearby forest for animals that he has seen around there over the last decade or more.

We will meet at 6:30pm at Don’s place just around the first bend of Hussey Road on the left. Bring a head torch and UV light if you have them – and warm clothes!

The UV lights have proven useful in highlighting some highly flourescent mosses, liverworts and other seedlings, but they are also known to pick up scorpions. I can testify that this is the case for at least one scorpion species that was spotted during my recent trip with Tony and Julie Bligh across the Simpson Desert. Paluma also has at least on species of scorpion so we might see one of these on the prowl this Saturday
