An Early Bird Not So Lucky When She Swipes Left!

Jan and I are leaving in two weeks to head back to Northern Territory for a few months and have been expecting that this would mean we would miss the mating rituals of the Victoria’s Rifle Bird (Ptiloris victoriae) …..yet again.

But we got lucky on Friday when we came back from shopping in Ingham and barely had time to sit down before a different call from a male VRB made us check out the feed tray and tree fern post out on the verandah.

And there he was, getting right into it … a very early bird by the entries in bird books which list the VRB breeding season as September to January, obviously with male competition for female partners pretty much done and dusted before our usual return to Paluma in late October.

We got lucky, but Mr Riflebird wasn’t so lucky, despite a very intense performance on top of the tree fern.

He started calling with wings upswept while facing the bushes off the verandah where VRBs, Honeyeaters, Catbirds and Satin Bowerbirds queue for the fruit buffet.

Still photos unfortunately don’t show the movements that go with each pose … with wings up, he kept in constant up and down motion by bending his legs while at the same time opening and closing his beak to get the bright yellow gape into the display.

Things were looking good when a female landed on the tree fern just below him and looked up, at which point he dropped his left wing and played some peek-a-boo by hiding his head behind the right wing.

Then the day’s ration of watermelon caught her attention and she dropped to the food tray. While he kept on with his performance she looked up, looked right but eventually swiped left, preferring watermelon to his advances.

He was so intensely focused and hormonal that he paid no attention to me moving around on the verandah to get better camera angles. Light was fading and I had to crank up the ISO to 3000 to get a workable shutter speed.

This morning I went looking for more information about VRB courting and couldn’t find much…except what would seem to be the seminal document on this subject written by Harry Frith and William Cooper and published in Emu, the journal of Birds Australia, now published by CSIRO.

Great abstract online at:- https://www.tandfonline.com/doi/abs/10.1071/MU9960102, but if you want to read the whole article online it’ll cost you 50 bucks American… if you want to download that whole issue of Emu that’ll cost you $230 AUD. Universities usually have deals that get their people open access to academic publications but my university contacts couldn’t get free access via JCU or Monash. The hegemony of the ‘big boys’ in academic publishing is a very vexed issue, even for those working in the academy. For the rest of us, bad luck.

But back to the joyful experience of watching this display of unbridled avian lust. In wings-up display, we get to see mauve feathers at the base of the wings and a mauve streak running back from the eye alongside the blue spangled cap. Wow, I said!

What we didn’t get to hear was what Frith and Cooper describe as “a vigorous alternate wing clap display that all but embraces the female with rapidly alternating wing extensions and synchronous jerking of the stiffly rigid head and neck between them at a progressively rapid tempo until copulation.”

Clearly once she swiped left that wasn’t going to happen!

Here’s hoping we get to see a few more displays before we disappear towards the north west for a few months.

Talking with other villagers today the question was asked about the apparently unseasonal courting behaviour … is this just a precocious individual bird or is this another sign of the “new normal” as we see more unseasonal animal behaviour and plant flowering and fruiting?

Love to hear what unusual biological phenomena others are seeing??

Footnote: For those unfamiliar with the phrase “swiping left” Dictionary.com offers this definition: (On the online dating app Tinder) indicates that one finds someone attractive (or unattractive) by moving one’s finger to the right (or left) across an image of them on a touch screen. “I swiped right, but sadly for me, she swiped left”.

Courtship Display and Mating of Victoria’s Riflebird (Ptiloris victoriae) with Notes on the Courtship Displays of Congeneric Species

Clifford B. Frith & William T. Cooper

“The courtship display and mating of Victoria’s Riflebird (Ptiloris victoriae) are described from numerous hours of direct observations and 117 minutes of videotape. Courtship display is typically performed on the apex of a vertical dead tree trunk stump and consists of three discrete components: Calling with the associated exposure of a bright mouth, a circular wings and gape display and a vigorous alternate wing clap display that all but embraces the female with rapidly alternating wing extensions and synchronous jerking of the stiffly rigid head and neck between them at a progressively rapid tempo until copulation. Subjective observations indicate that in immature, female- and sub-adult male-plumaged males the advertisement call is inferior in power and the courtship displays lacking in synchronisation and coordination of postures and movements. Victoria’s Riflebird courtship is compared with that of congeneric riflebirds and with other sexually dimorphic polygynous birds of paradise and similarities discussed. Contrary to previous views, the courtship display of Victoria’s Riflebird involves a progressive series of specific postures and movements increasing in tempo and leading to copulation. Some of its courtship behaviour is similar to that of other genera in the Paradisaeinae”.

More Winter Bird Watching at Paluma…..

Birdwatchers at Paluma continue to be delighted by the hive of activity amongst the local birdlife during these fine, sunny winter days. Here’s a further selection of birds seen and out and about in the village over recent days by Peter and Jan Cooke.

Seeking the Bridled Honeyeater !!

Honeyeaters are probably the most seen and most numerous birds in the Paluma village. Lewin’s Honeyeater, Macleay’s Honeyeater and the White-Cheeked Honeyeater are commonly seen. The Yellow Spotted Honeyeater is here also, but it is difficult to distinguish from the look-alike Lewin’s, other than by call. Paluma is also said to be at the southern edge of the range for the Bridled Honeyeater (Bolemoreus frenatus).

Wikipedia says the Bridled Honeyeater is a North Queensland endemic with a range that extends from the Bloomfield-Mt Amos area, south to Mt Spec. Its favoured habitat is subtropical or tropical moist upland forests and subtropical or tropical rainforests, usually above 300 metres. But in winter, it descends to lower forests including mangroves, and can sometimes be seen in more open habitats. It’s said to be mostly solitary and elusive, but when trees are fruiting or flowering they may gather in large, quarrelsome flocks.

Over the past four years of bird watching, Jan and I have seen the Bridled Honeyeater only twice, and not in down-town Paluma. Our observations have been recorded at Paluma Dam and out on Don Battersby’s little rainforest patch on his Hussey Road acreage block. The photographs below were taken at Don’s place in February 2017.

So, although Bridled Honeyeaters are unlikely to be here in winter, it’s surprising we haven’t seen them over four successive wet seasons in and around the village.

We’re wondering what observations others can share about this interesting bird with its bi-coloured beak, bright blue eyes and distinctive white eye markings. Have you seen the Bridled Honeyeater at Paluma?

Rainforest Biodiversity: 5 Easy Species Part 9- Vines & Climbers

By Jamie Oliver

Vines (as well as woody lianas) are a common and defining feature of tropical rainforests. Because they rely on rapid overgrowth of other plants for support, they are most frequently found in disturbed areas where there is ample light for rapid growth.

Vines and climbers share a growth form but (like animals that swim or fly) belong to many different and unrelated groups. They use a variety of methods to grow up from the forest floor and into the light near the canopy without having to invest in growing their own heavy and rigid trunks. Some climbers use thorns that catch on to adjacent leaves and branches, others use tendrils to clasp or twine around other plants, and others use modified roots to cling on to tree trunks.

1. Climbing Pandan (Freycinetia excelsa)

The climbing pandan is a very common leafy climber found growing up trees in the rainforest and is easy to see along Paluma walking tracks. It is related to the large Pandanus palm-like trees seen in open forests along the coast. Leaves are narrow and pointed with fine teeth along the margin near the base. Some stems can also be found growing along the ground near the base of their host tree.

Fruit are rarely seen but are red to orange elongate clusters of seeds. Flowers are surrounded by orange leaf-like bracts.

A second species of Freycinetia (F. scandens) also occurs around Paluma. It can be distinguished by its much broader leaves, which have a more uniform length.

2. Pothos or Candle Vine (Pothos longipes)

Pothos is another very common climbing plant found growing up tree trunks along the village tracks. The distinctive leaves provide the inspiration for its other common name – candle vine. The leaves have a constriction near the apex, with the remaining apical leaf portion shaped a bit like a flame. No other climber has this leaf shape. Pothos are another very common climbing plant found growing up tree trunks along the village tracks.

The leaves get progressively bigger as plant grows and change from upright and pressed against the tree trunk to long pendulous and downward-pointing. Larger stems can also be found growing along the ground near the bases of trees.

3. Yellow Lawyer Cane (Calamus moti)

This is one of a group of climbing palms variously referred to as Lawyer Vine, Wait-a-while, or rattan. They are most frequently found in forest openings and gaps caused by fallen trees or cyclones.

Several species of lawyer vine or wait-awhile can be found around Paluma. The most readily identified is the Yellow Lawyer Cane with its distinctive, robust, yellowish spines arranged in diagonal spiral rows along the cane stems below the leaves. The canes are often noticeably thicker than in other species.

The other common species along the tracks is the Hairy Mary (Calamus australis), which has finer brown spines and a frond with broader leaflets.

All species have palm-like leaves and spines growing from a sheath that covers the stem (cane). They also all have tendrils with vicious hooks emerging from the leaf bases. These tendrils hook on to adjacent trees which provide the support needed to climb up to the forest canopy. In older plants the lower part of the cane loses its leaves and spines and becomes a tangle of smooth flexible canes winding along the ground and up into the trees. In this form they clearly reveal rattan cane – the material that is widely used to make cane furniture.

4. White Supple Jack (Ripogonum album)

While this common vine has large bright green leaves, it is most easily identified by the leafless matt-green stems with irregular curved green spines that wind their way through the foliage at eye-level. The stems can be up to 3cm in diameter.

They are more common in areas that have been opened up to the light by a tree fall or along the margins of the rainforest around the village where there is ample light. There are some good examples of this vine along Lennox Crescent opposite the Paluma Pottery, and around the edge of the adjacent car park. Ripogonum has small white flowers and globular red fruit.

5. Atherton Raspberry (Rubus probus)

This rambling climber favours open areas and can be found in rainforest openings and at the start of the H-track on Whalley Crescent. There is another patch on the other side of the H-Track near the old fenced-off miner’s test pit and viewpoint over the adjacent creek. It usually grows no more than a few metres high and tends to lean over adjacent plants rather than growing up tree trunks towards the canopy.

R. probus has compound ovate leaves with 5-9 leaflets and the stems have widely-spaced fine thorns that are exceedingly sharp. The fruit looks like a small commercial raspberry.

There are 3 other species of native raspberry which can occur around Paluma and one of these (R. queenslandicus) is very similar, with slightly narrower and more pointed leaves. Based on leaf width, most of the raspberry patches around the village appear to be R. probus, but it’s possible that some are R. queenslandicus. To be perfectly safe when casually encountering a raspberry around Paluma you can have a bet each way and refer to it as Rubus probus/queenslandica. The fruit of both species is edible

Winter Bird Watching at Paluma

Whilst it might be winter and a little chilly at Paluma, it hasn’t deterred the local birdlife from getting out and about amongst the village gardens and adjacent rainforest. Paluma is always a great place to do a spot of bird watching. These fine, sunny winter days are ideal for a stroll in the village and the opportunities abound to catch a glimpse of some locally common species. Peter and Jan Cooke have done just that, recently sighting the following birds in their own garden and throughout the village.

Crimson Rosella tucking into the nectar-laden grevillea flower spikes at No. 56 Mt Spec Road. This stunning flower is Grevillea Moonlight, a hybrid of G. banksii and G. whiteana.

Another feasting Crimson Rosella, this time enjoying the powder-puff flowers of a red Calliandra.

This Eastern Spinebill was up at dawn to enjoy the flowers of Grevillea Firesprite.

Recently a pair of Grey Fantails have been cruising up and down Mt Spec Road….perching momentarily and then demonstrating great aerial acrobatics to take insects in flight.

Rainforest Tree of the Month, June 2020 – Flindersia species

A recent discussion with friends about a very large tree in their garden which was to have a limb lopped off, has prompted me to feature the species Flindersia as Rainforest Tree of the Month. The limb of the tree in question hung dangerously over the roof of their house. My friends understood this tree to be Australian Teak, Flindersia australis, but I questioned this as it did not quite match the characteristics of Flindersia australis.

The seed capsule collected from my friends’ tree, was still green and had a bumpy surface rather than the characteristic spiny surfaced, five valved seed capsules of the Flindersia australis. Nor did the leaflets of the compound leaves, being slightly curved, match the elliptic shape of those of Flindersia australis. The distribution of this tree is in rainforest from near Proserpine to northern NSW, at altitudes up to 750 metres. So, I feel that more likely candidates for my friends’ tree would be Flindersia acuminata, Flindersia brayleana, Flindersia bourjotiana or Flindersia pimenteliana, all of which are endemic to Paluma.

There are seventeen species of Flindersia world-wide; growing in New Caledonia, New Guinea, Malesia and Australia. Fifteen species are endemic to Australia. The species is named after Matthew Flinders (1774-1814), the renowned navigator and cartographer who led the voyage of ‘The Investigator’ on which the British botanist, Robert Brown, collected many Australian plants. Flindersias are members of the Rutaceae family.

Flindersia australis, also known as Teak, Australian Teak and Crows Ash,can grow to a height of 40 metres on rich, volcanic rainforest soil. It is somewhat smaller elsewhere. Sprays of tiny white flowers appear from August to February with the spiny seed capsules forming from March to January. Unlike most other Flindersia species, these segments do not separate into individual portions. The 35-50mm seeds are flattish and winged at the apex. The timber is in demand for general building, flooring and fencing. It has a high oil content and is readily flammable.

Flindersia pimenteliana is also known as Maple Silkwood, Rose Silkwood and Mountain Silkwood. This majestic tree grows to 30 metres high and may be buttressed. It occurs from Mt Finnegan near Cooktown to Paluma and also is found in New Guinea. The leaves, like other Flindersias, are compound but the leaflets taper to a narrow point. The flowers are similar in size to the inflorescence of the other Flindersia species but are red to purple. They appear from November to March and are difficult to see high in the canopy. The fruiting capsule, 55 – 115 mm long, is green to brown with five spiny valves. These split and release about 20 flat, winged seeds about 45-50mm long, from July to December.

Sulphur-crested cockatoos eat the seeds.

The timber of this tree was once used to make barrels and very decorative cabinet timber. Although young plants grow readily, they are not an economic tree to grow in plantations due to their spreading structure. Leaf material has been found to be active against some tumours.

There are several fine examples of Flindersia pimenteliana to be seen around the village. The easiest to find is in the stand of trees in the area between the tree ferns and the road cutting opposite the Rainforest Inn, (the kitchen end near the entrance to the motel units). Some still attached, green seed capsules hang just above eye level. Other trees can be seen at the end of Smith Crescent, at Number 20 and at the fence-line between Numbers 15 and 17 Mount Spec Road.

Flindersia schottiana is another tree which could possibly be found in the Paluma area as its distribution range is from Cape York to Port Macquarie at altitudes up to 1300 metres. This tree is also known as Silver Ash, Bumpy Ash, Floppy-leaf Ash and Cudgerie. A majestic tree, growing to 45 metres, it is rarely buttressed. The trunk features large bumps where old branches have been detached, hence its common name, Bumpy Ash. The tree has compound leaves with 7 to 9 leaflets, 50 to 260mm long. The upper-side of the leaves is mildly hairy with dense, fine hairs on the under-side. The tiny white or cream flowers are fragrant, appearing from August to December and in May. The five-valved fruit capsules are spiny, 80-130mm and release about 30 flat winged seeds from December to April. Flindersia schottiana is a pioneer tree, often found in regrowth areas and rainforest margins.

Flindersia acuminata, also known as Silver Maple, Silver Silkwood, White Silkwood and Ice-wood, occurs at altitudes up to 1200 metres in rainforests between the Windsor Tableland and Paluma. The tree can grow to a height of 40 metres and may be buttressed. The elliptic leaflets of the compound leaves are from 50 to 150 mm long, slightly curved, and tapering to a point. Fragrant white or cream flowers grow in terminal or axillary panicles from November to January. They are tiny, with five petals and are only about 3 mm in size. The fruit capsules, appearing from June to March are green to brown, 90 to 150 mm long and have five spiny valves which split to release flat, papery winged seeds, 65 to 80 mm.

Flindersia bourjotiana, also known as Queensland Silver Ash, Silver Ash and White Ash. The distribution of this tree is in rainforests from McIvor River near Cooktown to the Paluma Range at altitudes up to 1200 metres. The tree grows to about 35 metres and may be buttressed. The leaves are compound, with 3 to 9 elliptic leaflets, from 50 to 190 mm long. The underside of leaves can be slightly hairy. The tiny, (5-9mm), fragrant flowers can be white, cream or green and grow in terminal or axillary panicles, or sprays. Flowering occurs between April and January. Fruit capsules can be up to 150 mm long with five spiny valves which split to release several flat, winged seeds, 30-70 mm long. Sulphur-crested cockatoos and giant white-tailed rats eat the seeds.

Flindersia brayleana, is also known as Queensland Maple, Maple Silkwood and Red Beech. A tree growing to 35 metres, its distribution is from the Windsor Table-land to Mount Halifax near Townsville, at altitudes up to 1150 metres. The compound leaves have slightly curved leaflets, tending toward an ovate/elliptic shape and ranging from 60 to 210 mm in length. Tiny fragrant white flowers with five petals 3mm in size grow in terminal or axillary panicles from November to January. They are difficult to see high in the canopy. The fruit capsules, are 60 to 100 mm long, and have bumps rather than spines on the surface. They split into five valves, or segments, and release several winged seeds. Flindersia brayleana was once a common tree in rich, red, volcanic soils on the Table-land and on Mount Spec however, high demand for its exceptionally beautiful pink timber has caused it to become scarce. During World War 2, the timber was sought for use in aircraft production, such as in the manufacture of propellers and for ply-wood used in the Mosquito bomber aircraft. The timber was also used in rifle stocks and for beautiful decorated stocks in sporting rifles and shotguns. Boxes, barrels and window frames were also made from this timber. The timber can cause dermatitis.

Bettongs revisited

Following up on a comment from Michael Drew on the Eucalyptus grandis Tree of the Month article, I am reprinting an article from the August 2017 issue of Turkey Talk on the Bettong and its role in the health of Eucalyptus forests.

To remove any ambiguity regarding the identity of our local truffle-eater, the northern bettong (Bettongia tropica), I altered title of the original article from Potoroo to Bettong. Potoroos, close relatives of the Bettong, are only found in the SE Australia & Tasmania.

Of course it’s possible that the Republic of Hussey Road has its own endemic but undescribed species of Potoroo (Potorous husseyensis ??)

Jamie

[Bettongs] of Hussey Road are more than cute critters.

‘Truffles’ conjures up the ‘black gold’ now being produced in WA, Vic, NSW and Tas. However, there are also native truffles, mostly found under litter, which are eaten by small marsupials. These truffles are the fruit bodies of fungi which have probably evolved to fruit underground due to drying climatic conditions in Australia over 35myo. They are vitally important in a 3 way association -tree- truffle-marsupial.

More is becoming known about the importance of mycorrhiza in the soil in which fungi mycelia are attached to tree roots. It is a symbiotic relationship where the fungus receives sugars from the tree and the tree gets chemicals such as phosphorus from the fungus. Since the 1980s studies have shown a third component in the system that is the marsupials. To survive it needs small marsupials such as potaroos and bettongs to dig up the truffles and eat them.

Truffles contain a mass of spores and tissues with a distinctive smell to attract animals and also provide them with food. Spores pass through the animal and can be dispersed to a new location

Since many of our small animals such as potaroos and bettongs are endangered species, it is vital that this relationship is better known. Eucalypts are one of our native plants which are very reliant on truffles. It has been estimated that they and many other native trees derive up to 75% of their metabolic needs from this type of ectomycorrhizal association. If these marsupials disappear, one vital component in the ecosystem will be lost.

Other ectomycorrhizal fungi may occur in an ecosystem as well so it doesn’t mean the whole system will collapse. But in Australia there are many ecosystems which are less healthy and resistant than before.

Rainforest Biodiversity: 5 easy species Part 8 – Orchids

by Jamie Oliver

Orchids are the most diverse of all the flowering plant families with around 25,000 species world-wide and around 1,600 in Australia. They can be terrestrial or grow on rocks (lithophytic), or on other plants such as trees (epiphytic), or on rotten logs. While some have large, showy flowers, many can be small, inconspicuous plants with tiny delicate flowers of various hues.

While there are several orchids that can be found around the Paluma village and surrounding tracks, their scientific names are currently in a state of flux, with 4 of the ‘5 easy species’ listed here having had their names changed by one group of scientists, but contested by another! Here we will use the names published by the Atlas of Living Australia, but if you use the very good online key to Tropical Rainforest Orchids, you will need to be aware of the alternative scientific name given after the “=” sign).

Remember that it is illegal to collect any orchids from the wild. Several species have suffered from serious decline due to unscrupulous collectors.

1. Christmas Orchid (Calanthe australasica)

This is one of the most common and easily recognized species around Paluma. It is a terrestrial orchid with large pleated leaves. As its name suggests, it flowers around Christmas time (October – February) with a rather showy mass of white flowers on one or more stems. Under the shady canopy of the closed rainforest these orchid plants occur at irregular intervals, but in more open areas on the edge of the forest they can spread to form substantial patches. There are good examples of this orchid along all the village tracks.

2. Slender Cane Orchid (Dendrobium adae = Thelychiton adae)

This is the most common of the epiphytic orchids that can be seen on the upper trunks and limbs of trees along the village tracks. You can also find it at ground level on the limbs of recently fallen trees or on large rock outcrops. It can be identified from the cluster of distinctive pencil-thin, often grooved canes with a few (max. 6) leaves near the tip. It can also be found on rocks. The white to pale yellow flowers are small (around the size of a 5 or 10 cent coin) and appear from July to October. There are several good examples of this orchid along the H-Track and in several open areas around the village. This species is restricted to high altitude rainforests and sheltered areas of wet forests from above 700 m from Paluma to the Tablelands.

3. Rock Orchid (Dendrobium speciosum = Thelychiton jonesii var. bancroftianum)

This is a well-known and widely distributed lithophytic and epiphytic orchid with large bulbous stems (pseudobulbs) topped by large leathery leaves. It is common in many Paluma gardens where it can form massive clumps. Large clumps of this orchid can be found on rocky outcrops in full sun along tracks around the Paluma Dam (Lake Paluma), but along tracks around Paluma village it forms smaller, less conspicuous clusters, usually high up on trees. Flowers mostly vary from white to creamy yellow and appear from September to November.

There is another species recorded from this area which looks nearly identical (Dendrobium jonesii = Thelychiton jonesii var. jonesii) and can only be distinguished by its slightly smaller flowers and earlier flowering period (September-November). Some taxonomists have lumped both into a single species, so it might be safer to call any of these orchids Dendrobium speciosum/jonesii and leave the final determination to be resolved by the experts!

4. Cupped Strand Orchid (Bulbophyllum newportii = Adelopetalum newportii)

This native north Queensland orchid is quite common but often overlooked due to its small size. It has a creeping rhizome that grows up trees or rocks and produces regularly-spaced, small, globular, green pseudobulbs (8-15 mm), each with a small, sturdy, green leaf up to 70mm. It produces bunches of up to 8 small (50mm), white to cream or greenish flowers from September to December.

In areas at the edge of clearings or on fallen trees it can be found near the ground but otherwise it is higher up in the forest canopy where the light is stronger. It can be found around many of the public areas in the village.

5. Buttercup Orchid (Dendrobium agrostophylla = Trachyrhizum agrostophylla)

This beautiful small epiphytic or lithophytic orchid can be found in open forest near the edges of rainforest or on tree branches overhanging open sunlit streams. In favourable conditions it can form dense patches.

It has slender cane-like stems that look a bit like Dendrobium adae (see above) but they are more spaced out along a creeping rhizome rather than occurring in bunches. It also produces leaves along a greater portion of the stem. The perfumed flowers are bright yellow, appearing from July to November.

Breakfast Bombing by Birds

Macleay’s Honeyeaters are pretty fearless little creatures.

As Jan Cooke stepped onto the deck today to enjoy a morning juice, suddenly she was ‘breakfast bombed’ by one of the cheeky Macleay’s Honeyeaters who pretty much dominate the fruit station. Such is life in downtown Paluma!

Thankfully the scrub turkeys aren’t as bold……..!

Jan Cooke with her very friendly Macleay’s Honeyeater. What’s for breakfast?

A Pied Piper for Paluma

Rain, Rats, and Cannibalism

The wet weather always brings birds and a few bush creatures to shelter and seek food on my back deck. For the last two mornings birds in greater numbers than usual have come in, ravenously emptying the food dish then sitting huddled together, wet and bedraggled along the railing. Even a brush turkey, much to my chagrin, joined the throng. Lord Victoria (the senior Rifle-bird) was first in, just on daylight clinging to the back door and screeching for attention. He was joined by a junior male and a female; a Catbird (who didn’t stay with the mob); two female Bower-birds; about a dozen Macleay’s honey-eaters, who fly into the kitchen if, in an unguarded moment, I leave the screen door open, and a mob of noisy Lorikeets who squabbled and jockeyed for position all morning.

A not so welcome guest was a huntsman spider, fortunately not a big one, who moved into my bathroom but the most unwelcome guests over the past three weeks were rats. Bush rats have invaded the laundry while White-tailed rats have patrolled the laundry and decks, creating havoc. An Antechinus made it to the kitchen and I dread the day when a White-tailed Rat discovers it can enter the house with no effort at all by using the dog-flap.

Every night for the past three weeks I have set mesh traps and almost every morning had a captive to take to the release site at the forest edge. First was a White-tailed rat who did considerable damage in the laundry before he was trapped. Then, for five days in succession I took Bush Rats to the release site. Next was a young White-tailed rat. There was a lull for two days then two bush-rats and an Antechinus went to the release spot. Yesterday, a very big White-tailed rat was captured – so big he totally filled and could not move within the trap. In another small trap two bush rats were caught. To my horror, one rat had begun eating the other. Is this cannibalism a symptom of stress? Is this behaviour rare?

A young rat probably a white-tailed rat) awaiting “transportation for stealing bread” !

Again, this morning I took a Bush Rat out to the release site. I wonder if any other residents are experiencing unusual numbers of visiting rats.

I am beginning to feel that I need a Pied Piper in Paluma.

Yellow-footed Antechinus – Antechinus flavipes;
