The Cairns Aquarium-A Pleasant Way to Spend a Wet Sunday

The best new attraction in Cairns is the Cairns Aquarium. This wonderful tourist attraction is located near the Cairns Esplanade and features three floors of well-designed and maintained exhibits that are bound to entertain and amaze all visitors. Local reef fish and freshwater fish are featured in fantastic settings.

In addition to the fish there are a number reptiles, amphibians and insects on display. There are a few 'touch and feel" areas where people can become familiar with a number of different kinds of reef and tropical biota.

A wonderful restaurant adds to the enjoyment of the place with tasty, well-presented food.

Surely with the Cairns Botanic Gardens, the Cairns Aquarium are the two top tourist attractions on the mainland.

A few hightlights.

They Did It Right On Our Doorstep

This needs little explanation. But this is what we saw first thing this morning.

Now where did he go?

New Kids On The Block

The other day I was sure that we had a new pair of cassowaries on the site. Today it was confirmed.
When we got out of the car, these two greeted us.
It's a small male, probably quite young as indicated by the short wattles and the bub is young too. It's still in the "squeaking" stage and depends on Dad for food. It is much smaller than the three young of the year from the usual pair that occupy this territory. And, by the way, this morning Mom and Dad were doing it right on our front doorstep as you will see in a future blog. (But you never have a camera when you need it.)
This pair were intent on picking up the palm seeds for a couple of species growing on our property. The seeds themselves did not seem to have much flesh on them but the birds ate all they could.

We felt that this male knew our place and perhaps was one of the young birds fathered by our resident male. What will happen when these new birds meet up with the residents can only be imagined. The resident male seems much larger than this one and the bub is completely dependent on him. The residents will attempt to drive this young male from the territory.

Recent logging on Black Mtn Road may have driven these birds from their regular haunts and they have ended up within the territory of the resident male and female.
Good luck little guy. And you will have to have eyes on the back of your head to survive in this world.

New Book!

Another new book authored by a local has just appeared.

Local naturalist and tour guide leader Jun Matsui has written a comprehensive guide to the birds of the Cairns and Tablelands region of Queensland Australia. The text is in Japanese and caters to the needs of Japanese visitors who come to the Australian tropics for bird watching.

The book contains hundreds of photos taken by the author, They are all in poses that assure identification. Non-Japanese speaking locals will be able to use the book because each caption is in English. In addition, there are sections in the book in English. Chapters in the beginning include external morphology and a bird list. The bird sequence is arranged taxonomically with a colour thumb guide provided on the margins. There are maps, places of interest and things to do. A comprehensive index in both Japanese and English.
Thew book can be obtained from the author at $A60.00: 松井淳

But wait, there's more!! Phil Gregory tells me that an English translation is in the offing and should be available by the end of the year.

Nice Cricket, Awful Name

Pseudotrigonidium australis (Chopard), adult male in typical pose

This little cricket was described by Lucien Chopard, a legendary French entomologist in 1955 as Tremellia australis. Fair enough. The name is simple and easy to remember. But in 1999 a Russian entomologist taxonomically massaged the tribe resulting in a lot of splitting. Tremellia was redefined and T. australis did not fit the new concept of Tremellia. So it was transferred to the larger genus Pseudotrigonidium. Further he established subgenera within Pseudotrigonidium, but apparently left the sole Australian example, T. australis, and a couple of other species from Borneo, in neither of the two allotted subgenera. So it becomes Pseudotrigonidium australis (Chopard)- the Kuranda Tree Runner.

In dealing with this taxon for the Guide to Australian Crickets to be published by CSIRO, we had to try and discover what the species really looked like. The type was an old specimen, tattered and discoloured and without precise locality date. Otte and Alexander in their monograph collected some specimens from near Kuranda.

As luck would have it, the species was discovered literally in my own backyard. The living crickets look nothing like the type nor the preserved specimen collected by Otte and Alexander in 1960.
 When viewed closely, the crickets are very colourful with brown and yellow markings seemingly aiding in camouflage.
Even the head is distinctive with stripes and light-coloured patches. In life the eyes have a greenish tinge.
 Pseudotrigonidium australis (Chopard), adult male in typical pose
The crickets have a very distinctive posture. They always are directed downwards, legs askew.They have extremely long antennae and excellent eyesight. The antennae are in constant motion. When disturbed they dart downwards but in a spiral fashion to attempt to confuse the predator. Since they cannot fly, the utilise both their colour pattern as the first line of defence followed by their extremely fast movements.

Males sing from tree trunks after dark. This continues through most of the night into the pre-dawn hours if the weather is warm and not too wet. Adults and nymphs can be found on the same tree trunk. It is interesting that not all trees are inhabited by the crickets. If there is a pattern, the desired trees have furrowed bark and have some growth of lichens. Also the diameter of the tree does not fit a pattern. Trees of 8-9 cm can have crickets as well as those 10 times that diameter. Females supposedly lay their eggs in the cracks in the bark. These crickets occur from the Daintree south to the Kuranda Ranges. We have not found them in the Atherton Tablelands.

End of the Line

It's that time of year when some of the big Golden Orb Weavers are in their last days. They neglect their webs and do not eat very much. Males are not found and females descend to the ground to lay their eggs. In addition, Black Butcherbirds seek them out and pull them from their webs. During previous weeks, the spiders seem to avoid being picked off by the birds. Perhaps, the untidy webs are a giveaway for the spiders late in the lives of the orb weavers.

They are beautiful spiders when you see them up close. And they can see you. They are quick to dart to the we's edge when you approach.

Cassowary Update

The three youngsters are still growing and they still continue their characteristic peeping. This becomes more enthusiastic when the food source is is to their liking.

But the end is neigh. The chicks are just about the right size for their lives to make the next change. That occurs when Pops decides enough is enough and he drives them away. This seems sad because the chicks do not seem to understand what is going on with their father. He was protective and attendant yesterday but today he is antagonistic. Actually this behaviour may be initiated by the female when she comes into season.

 Nice garden bird, eh?

Some colours beginning to appear and the wattles are developing
