My South Aussie Garden

15 Jun

Dear Reader

The people of Adelaide have the luxury of a glorious Mediterranean climate; cool and wet in the winter, mild to warm during autumn and spring and hot and dry in the summer. Such benign weather combined with the city’s ideal location between hills and coast provide excellent conditions for gardening throughout the year. Viewed from the hills, the city looks like a green patchwork of tiny gardens, expansive parks and tree lined boulevards. In general, South Australians take great pride in their gardens creating personal spaces that provide a sanctuary in a modern urban setting as well attracting local wildlife into the city.

My own garden, like that of many Adelaideans, is a combination of native shrubs, trees, lawn and exotic flowering plants, all carefully chosen to give colour throughout the year and attract both birds, insects and the occasional reptile. Small areas of lawn and strategically placed rocks provide variations in terrain while outdoor seating and water features add aesthetics plus an all important source of moisture in the summer months.

A couple of sizeable eucalypts dominate the back of the garden. The smaller of the two has large yellow flowers that blossom in the spring and tends to attract a wide variety of parrots, especially rainbow lorikeets. The larger tree has smaller, white flowers that seem to be at their best around Christmas. The  snowy blossoms are a favourite food for several different  species of honeyeaters including the largest of all; the wattle bird whose raucous cry sound remarkably like wakeup…wakeup.

Several different species of lizards are quite common around the garden. Marbled geckos live amongst the brickwork and a variety of slender skinks including sliders and cenotus scurry under the leaf litter and rocks. Occasionally a blue tongue or shingleback makes an appearance during the summer months.

Spiders and insects are found in a myriad of micro-niches throughout the garden. Flower spiders hunt amongst the blossoms, red backs live in the dark recesses of garden sheds while various beetles, wasps and mantids (to mention just few groups) forage amongst the diverse shrubs and grasses.

AD Leaf curling spider

This is a merely a brief introduction to my garden. In some of my future posts I hope to share much more detailed stories and observations about the animals and plants that   I encounter each day in my own garden and others that I might visit around the state.

Misty Morning Rats

9 Jun

 This year, the first few days of winter have been a little cloudy with a light mist over the city in the early hours. It is the kind of weather that encourages a cup of coffee, at the Par 3 Cafe by the Torrens Weir, before my weekend bike ride around the river trail. But the cool quiet mornings do have one distinct advantage. Some of the more reclusive creatures that inhabit the river banks seem a little less wary and easier to find; most notably…The Australia water rat…one of my favourite species.

As you can imagine, misty mornings, shy wildlife and carrying a camera on a bike does present a few challenges. My digital SLR and long lens are too heavy and the low light conditions push the compact super zoom that I can comfortably wear on my hip, to its absolute limits. Consequently, please excuse a couple of the rather grainy images that I have included later in this post. However, the mere fact that I was able to capture these pictures encourages me to share them and their story with you.

Over the many years that I have walked or cycled around our permanent creeks and wetlands I have only caught the occasional glance of Australian water rats. The tell tale ‘V’ shaped wake that they leave and their low profile in the water make them unmistakable. Unfortunately, after a brief appearance they invariably dive or disappear into the tangle of reeds and grasses on the water’s edge. It is also quite easy to confuse them with common rats, which swim well and often live close to waterways. Unlike their terrestrial cousins, water rats are a little more robust have a slightly blunter face with a heavier covering of whiskers. Their back feet are also webbed and they have a white tip to the tail.

Back to my tale of coffee and misty mornings; last Saturday I had cycled from home to the weir and was peddling along the track that runs south above the river when I noticed a classic ‘V’ shaped wake in the water. I quickly dismounted, whipped off my helmet and gloves and pulled out my camera. The water rat swam upstream diving periodically and I was able to walk slowly along the trail watching it for around 5 minutes. Eventually it disappeared into the undergrowth near the bank but not before another one paddled close by affording me a rather unique photo opportunity. However, as I mentioned at the start of this piece, the light conditions were far from perfect and my target animals were the best part of a 100 metres away. A lot of frames and little Photoshop produced the two images you can see here.

Encouraged, I returned the next day and sat quietly on the bank for the best part of an hour, hoping for a repeat performance. I did see one water rat for a brief moment but I could not focus rapidly enough to get a clear image. At this point, the coffee beckoned and I cycled back to the weir stopping a couple of times on the way to enjoy the winter’s early scattering of leaves on the river bank and watch a pair of silver gulls wading in the water cascading over the sluice gates.

Now that I know there are several water rats in the area I am determined to travel the same path on foot over the next few months with my DSLR to see if I can improve on these pictures. But for now I am thrilled to have seen the little animals foraging in the wild and to have captured a few simple images.

 

Until next time

South Coast Sealions

31 May

Dear Reader:
Last weekend I was walking along the rocky foreshore of the Deep Creek Conservation Park at the tip of the Fleurieu Peninsula around 90 kms from Adelaide. A few metres from the shore a rush of water and a speeding grey shape caught my attention. ‘Dolphins at play’ was my first thought but a closer look dispelled that idea. The twisting motion was suddenly more than a little familiar… sealions. A pair were frolicking or fishing close to the rocks on the inside of the powerful rip current that surges between KI and mainland. They were too fast for me to take a shot but my thoughts drifted back to my first encounter many years ago in this same stretch of water.

AACP1070291 edit

We were *spear-fishing along this same section of coast on a day that would have been better spent sleeping in. There was a stiff sea breeze and the visibility was around 2 meters at best. I was returning to the surface after scouring a rocky ledge near the bottom for zebra fish and just one hard kick of my fins from the next breath of air when a grey shape rocketed out of the gloom just below me.  In an instant my assailant turned to face me with breathtaking agility. Instinctively, I raised my spear gun, slipped off the safety and prepared to meet either a bronze whaler or white shark.

AADzebra 2 edit

Needless to say, my reflexes combined with the drag of the water meant that by the time the predator had reached me the gun was in no position to be of any use. The next moment I was face to face with my attacker. The large bull sealion came to a sudden halt, only inches from my facemask; its formidable set of teeth, bushy whiskers and baleful eyes providing an image that stays with me to this day. The sea lion performed a few more acrobatic turns as if to point out my ineptness in its watery home then disappeared back into the murky depths.

AAEsealion 8red

Australian sealions (Neophoca cinerea) are a threatened species that inhabit the temperate waters of Western Australia and South Australia. They grow to around 2.5 metres in length and weigh up to 300Kg; the males are larger than females. Sealions feed on fish, molluscs and crustaceans and in the past were persecuted by fishermen and hunted for blubber and meat. Unlike seals, sealions move comfortably on land using their flippers rather than dragging themselves. They have external ears; hence their family name Otariidae . Sealions breed on isolated beaches and rocky platforms often with rock pools close by where the pups can swim safely while being weaned. Their major predator is the great white shark.

AABsealion 5 edit

This was not my last encounter with these glorious South Australian mammals but it was my first and most memorable. In a later blog I will tell you about an exhilarating weekend on Kangaroo Island photographing sealions.

Rare Birds on the Beach

16 May

Dear Reader:
This week’s post is coming to you from Southport, a surf beach just south of Port Noarlunga but still sheltered by the reef (see Jan 21st post). I am sitting in a small cafe sipping a cup of coffee and reflecting on the last couple of hours spent wandering through the sand hills and along the beach.
I had driven to Southport in the early afternoon with the specific intention of walking along the tidal flats, where the Onkaparinga estuary drains into the sea, to photograph crabs and wading birds. However, I had not counted on such a high tide; the mudflats were covered and I could only access the walking trails that meander through the sand hills from beach on the seaward side.

A Southport Beach, estuary with bridge in the background red

I parked by the roadside and crossed the river on a small bridge below the cliff line and spent a few minutes watching anglers casting for bream and garfish. Nearby, a father and son paddled a sea kayak towards the ocean disturbing a small flock of black swans as they edged close to one of the steeper banks where the sandy slope of the dunes ran into the water.

B Kayaking below the cliffs red

As I traversed the final set of dunes above the beach I felt the afternoon sea breeze on my face and caught the muffled crash of waves breaking on the shore. Several surfers were enjoying a choppy break and more adventurous anglers were wading into the white water to cast for salmon. I headed down to the sand to find one of the trail entrances to the dunes that open onto the beach. As I trudged through the soft sand I noticed a group of diminutive shore birds racing between the foamy lines of waves curving up the beach. At first glance they appeared to be similar in appearance but a more critical look through the telephoto revealed a mixture of species and sexes.

D Mixed group of waders foraging between waves red

One particular pair stood out amongst the others. I held my breath, refocussed and squeezed off a series of shots, dropped to one knee to better incorporate the water into the background and fired again. I was photographing a pair of hooded plovers, an endangered species that nests on open beaches and a bird that I had only glimpsed at a distance along the Coorong’s extensive beaches further south. As I captured the last image, the wind picked up and the little flock of waders lifted as one and flew further down the beach.

E Hooded Plovers red

A sat for a few minutes, smiling inwardly as I reviewed the images then continued down to the trail entrance. As I climbed back up into the dunes I reflected on the extraordinary beauty and diversity of this stretch of coastline, a mere 20 Kms from the city centre. Walking through the dunes was like entering another world made up of: low scrub, wiry grasses and a thick layer of undergrowth fashioned from the skeletal remains of branches and tree trunks. I walked slowly and paused frequently observing a variety of insects, several lizard species and an assortment of birds including: honeyeaters, magpies and crested pigeons.

C View of the beach from the dunes in the afternoon light red

But today it was the ocean that called and as the light started to fade I took another track down to the shoreline and worked my way back to the section of beach where I had encountered the plovers. Sadly, the plovers were long gone but a little group of red capped dotterels remained, bedding down for the night in the footprints that I had left in the sand when I walked this way just an hour ago.

F Red Capped Dotterels bedding down for the night red

My coffee is finished now and it is time to drive home and share this afternoon with you.

And yes, dear reader, I missed the tide but somehow I think it might have been for the better.

Adelaide’s Parkland Rosellas

4 May

Dear Reader Adelaide’s CBD is surrounded by parklands. They are a place for workers to enjoy during a lunch break or cyclists and joggers to traverse on the daily commute. They set the tone for the city and also provide a natural backdrop to the everyday business of the state’s vibrant capital. They were conceived by the city’s founder and first governor Colonel Light and are still treasured and protected by those who live in the city and inner suburbs.

AA bike linear park

The ecology of the parklands like the commerce of the city has its own rules and hierarchy. magpies and miner birds aggressively mark out and defend their territories, brushtail possums enjoy the nightlife and screeching rainbow lorikeets seem to know everyone’s business.

AB Noisy Miner feeding on a banksia bloom

One of my favourite animals in this urban ecosystem is the elegant and colourful eastern rosella. They are found throughout the Adelaide and Mount Lofty region and seem to have a preference for open woodland where they can find suitable nesting holes, preferably in old growth trees. There has been a pair raising their young in a white cedar in front of my home this year and when I go for an evening walk I can hear the young ones deep in the tree calling to the adults.

AC Male and Female Adelaide Rosellas feeding

Male and female eastern rosellas feeding

Adelaide rosellas are around 35 cms in length with females being slightly smaller with a faintly orange cast to their plumage and less defined markings. They create a nest up to a metre deep within a tree hollow. Both parents feed the young. Rosellas are mainly seed eaters and feed mainly on the ground.

AD Adelaide Rosella on parkland fencepost feeding on wild grain heads

For me, one of the attractions of rosellas is their is its truly unique South Australian connection.  Indeed one particular type, the Adelaide rosella,  only occurs within a few dozen kilometres of the city. It is actually a hybrid of the yellow rosella which inhabits the Murray River valley and the crimson rosella which is more prevalent in the south east of the state.

AE Social interaction between Adelaide Rosellas above nesting hole

If you walk through the parklands during the spring and summer months it is not difficult to observe these colourful rosellas exhibiting a full range of behaviours from feeding to nesting and mating.

Waterfall Gully’s Aquatic Skinks

27 Apr

In the driest state on the driest continent water is, as you can imagine, the most precious of commodities. To be entirely honest, Adelaide has a wonderful climate but in summer we can go for many weeks without a drop of rain. During this time the few spring fed creeks that flow down from hills become a refuge for a wide variety of wildlife.  

AA edit

Waterfall above the creek

Frogs, native fish, fresh water crustaceans, aquatic lizards and certain bird species all need this permanent source of water. The spectacular little falls that have carved out Waterfall Gully on the city’s eastern fringe feeds one of the few environments where water dependent wildlife can survive the harsh summer months. At the foot of the falls; a restaurant, walking trails, and car parking sit adjacent to the creek making it a wonderful place for hikers, casual visitors and naturalists alike. 

B edit

A spotted marsh frog amongst the reeds

 After a particularly dry start to autumn I decided to drive out to Waterfall Gully to assess how the wildlife was coping with the conditions. A friend told me that he used to see quite lot of water skinks in the area years ago. I had only caught the occasional glimpse of the little lizards while cycling around the Torrens Lake in the city or on the banks of the Murray. This seemed like the perfect time to try to get some better images of these fascinating little reptiles. 

AAA edit

The creek provides a secure environment for many creatures including snakes, lizards, frogs and fish

Water skinks, actually the eastern water skink (Eulamprus quoyii) grows to around 30cms in length. They hunt for small invertebrates in and around permanent water. These lizards are territorial and males and females look alike. Up to 9 well developed young are born in the summer. They are common prey for Kookaburras, snakes and feral cats. Like most skinks, eastern water skinks can drop their tail when grabbed as an escape strategy and often have shortened or partly re-grown tails.

E edit

 On my first trip I drove up the narrow road to Waterfall Gully and parked the car close to the creek below the falls. Within a few minutes I had spotted my first lizard. It was sitting on a flat rock in the middle of the creek and had a substantial part of its tail missing. Around one in ten of the skinks that I saw that afternoon were missing parts of their tails.

C edit

This little lizard got away but not without losing part of its tail

 As I walked towards the waterfall I noticed that the skinks were quite abundant throughout the creek and its banks. Some were tucked into the undergrowth while others were foraging amongst leaves and twigs that had accumulated between the rocks in the creek bed. I did not see any swimming though a few were partially immersed in water, apparently waiting for prey.

D edit

 I returned to Waterfall Gully several times over the next few weeks to watch the water skinks and try to capture some better images. On my last excursion I sat quietly by a section of creek for over half an hour watching the lizards, small birds and insects that lived there. The wildlife had survived the ‘big dry’ quite well it seemed.

Arkaroola’s Emus

19 Apr

Dear reader 

This last week has been quite exciting. Old friends visited from Texas and, as is our custom, we headed to one of the most remote areas of the state to indulge our passion for wildlife and wild places. My choice was Arkaroola a place that I had visited many years ago on an indigenous cultures study tour and an environment I was eager to experience again.  

Arkaroola is a world heritage listed site in the northern Flinders Ranges 600kms north of Adelaide. It is a landscape of harsh granite peaks and deep, enchanting gorges; a favourite haunt for off road drivers, bush walkers and naturalists. Despite its isolation, facilities at the visitor centre are first class providing accommodation, a restaurant, supplies and fuel.

C Dry creek bed near Arkaroola with Sturt Desert Pea in the foreground

The road from Wilpena in the southern part of the ranges to Arkaroola is largely unsealed and traverses an iconic selection of Australian arid zone bushland ranging from wide brown plains and grassland to forested scrub. The road is traversed by numerous ephemeral creeks some of which wind back into interesting rocky gorges. Each time I have driven this route the wildlife that I have encountered has been different; flocks of parrots and red kangaroos one year, sightings of a variety of lizards and raptors another. However, it was my last drive north that was most memorable.

B Driving to Arkaroola

The first section of the road from the classical little outback town of Blinman with its pub, art gallery and general store, was largely uneventful. A few wedge tailed eagles soared on thermals in the distance and a couple of small flocks of corellas and galahs screeched at us as they took flight from larger eucalypts in the dry creek beds. The only kangaroos were road kill victims.

A Blinman the last outpost before a long bush drive

Around 50 kms north of the town we drove a little way up one of the creek beds clattering over the flat rock and sand in 4WD then parked in the shade of some taller gum trees for a bite to eat. Almost immediately, a male Eeu guiding his procession of chicks, emerged from behind some bushes where they had been feeding. As we approached he sauntered off up the creek with feathery rump swaying and his little family ‘in tow’.

EA Male emu with brood of young stripy chicks

Emus are the world’s third largest bird after the African ostrich and Australasian cassowary; they grow to a height of 2 metres and can weigh almost 40 kgs. Emus run at speeds over 60 kph. This bird had to be a male as only males incubate the eggs and care for the young.

A Emu bad hair day

This was the first of many encounters over the next few days. Perhaps the most unforgettable was just a few kilometres outside of Arkaroola. We were rounding a sharp bend in the road when a pair of emus suddenly appeared on the road hurtling towards us. The pair seemed oblivious to our presence and wholly engrossed in some kind of emu ‘high jinks’. They pushed and shoved at each other while still running, one falling sideways, rolling over then leaping into the air to continue the game. We skidded to a halt and watched them cavort privileged to see such a candid display of exuberant animal behaviour. After a minute or so they settled down and wandered up a rocky together slope feeding.

Our final emu encounter occurred near one of the few permanent waterholes in the region. Two large birds suddenly appeared from the scrub and ran alongside the vehicle for a couple of hundred metres then abruptly cut across us and headed for a stand of tall eucalypts. We pulled over and walked slowly down to the trees and watched them join up with another group and start drinking. In the soft evening light, the scene was really quite unforgettable and the Emus though aware of our presence, did not seem uncomfortable allowing us to capture some memorable images.

Mad March Possums

5 Apr

Dear reader

Each season in our southern state has its own natural highlights, For many March in Adelaide is a very special month; one where culture and wildlife seem to interconnect in rather unusual ways.

The city of Adelaide is separated from the outer suburbs by over 760 hectares of parklands. They consist of playing fields, open woodland, creeks and gardens. Most of the year, the parklands are frequented by joggers, cyclists and picnicking families. However, each March the serenity of the eastern parklands is replaced by the roar of V8 motors, the rhythms of international music and a surreal feast of various performing artists.

A Open woodland environment of the Adelaide parklands

Now, you would think that such an onslaught of humanity; its sounds, lights and smells would frighten the daylights out of the parklands’ resident wildlife. Admittedly, the local birds do seem a little more nervous and the resident bat population somewhat more erratic in their coming and goings. On the other hand, the possum population seems to relish the activity. Although they are not obvious to the casual observer, when the troubadours, drivers and musicians retire for the night these masters of the nocturnal world emerge to search for the spoils of the day.

Over the last few years I have enjoyed the city’s March festivities and often wandered down the east end to take in a concert, play or watch the ‘V8 Supercars’ burn up the track. This year, I decided to walk home after a late night performance and was more than surprised to see a couple of common brushtail possums foraging near an overflowing trash can. Normally solitary, these cat sizes marsupials seemed indifferent to each other as they sought out some apple and banana leftovers, a welcome change to their usual diet of leaves, buds and native fruits. I was aware that possum numbers had generally declined throughout the state due to habitat changes and predation by feral animals, most notably cats. I watched them for a while thinking to myself that if a little party food on the side bolstered their survival chances who was I to take the purist stand on natural diets for our indigenous species.

Unfortunately, I was not carrying a camera and decided to return the next evening at the unearthly hour of 4 am armed with my DSLR and long lens, in the hope of capturing a few shots. I was not disappointed. One particular animal that was sitting by the side of a trash can taking stock of the menu decided to climb up into a nearby tree as I approached. Staring defiantly at me as I adjusted the flash setting to suit the telephoto, it conveniently struck a number of typically possum-like poses then promptly disappeared into the upper branches once the modelling session had finished.

I crossed to the other side of the road and scanned some native pine trees with a high powered flashlight. The stand of trees was situated just inside the perimeter fence of the aptly named ‘Garden of Unearthly Delights’, one of the festivals most notorious attractions. I was hoping to flush out a ringtail possum, a smaller less frequently seen species. Unfortunately there were none to be found but I did manage to find a brushtail climbing the trunk of a large pine using its prehensile tail to hold on while testing the capability of a smaller branch to bear its weight.

On the whole it was a successful night though I would dearly have liked to see a ringtail. Perhaps another night when sleep eludes me and the lure of the city’s indigenous nightlife beckons I’ll capture that image.

A Drive Along the Beach

20 Mar

Dear Reader

At the southern tip of the Fleurieu Peninsula the rocky cliffs and granite outcrops of Victor Harbor and Port Elliot subside into a long stretch of pristine sandy beaches. They are the product of aeons of erosion and define the area where Australia’s longest river, the Murray; meets the ocean. The beach is easily accessed from the old river port of Goolwa and the short 5 Km drive along its length is only possible in a  4WD vehicle, Even then, it is best to keep a close eye on the tide and have a little experience driving in soft, sandy conditions.

Four wheel drive entry to Goolwa Beach

Over the last few weeks I have made the trip several times to photograph and observe the wildlife that lives along the tidal zone and in the windswept dunes. Twice, I reached the river mouth and once I had to turn back as the high tide and churned up sand made the going a little too difficult for my SUV.

The surf breaks for several hundred metres out to sea along this beach and sometimes you can be lucky enough to see a dolphin or the dark outline of a whaler shark hunting for Australian salmon or mulloway in the waves. However, most of the time it is the caspian terns that dominate the open ocean as they dive for schools of baitfish or rest on the wet sand ready to set off and hunt again.

You've done something different with your hair

You’ve done something different with your hair

In the shallow surf break a dozen different species of waders can be seen each exploiting its own niche with its specialised beak and hunting style. Diminutive sanderlings and dotterels race along the sand in between the wave fronts gleaning tiny invertebrates and worms too small to see. Small groups of oystercatchers use their broadened beaks to dig out cockles and prise them open while avocets use their slightly upturned bills to catch tiny crustaceans and other invertebrates swimming in the shallow water. In fact, what at first glance appears to be an homogenous continuum of beach; is in reality, a collection of micro habitats or niches, each exploited by its own particular species of bird.

I hope you enjoyed this jaunt along the beach and stay tuned for more South Aussie  adventures.

Golf Course Birdies

9 Mar

Dear Reader

Adelaide has a diverse collection of golf courses. They wind along the coast, straddle the hills face and even overlook the heart of the city. Their well-watered fairways, native bushes and towering trees provide an attractive habitat for a wide variety of wildlife ranging from kangaroos and possums to waterfowl and colourful parrots.

Well watered fairways and a diverse collection of shrubs and trees provide an enticing array of niches for different bird species

This week’s story comes from one of the two inner city courses that stretch between the Torrens Lake and the fine old villas and tree-lined streets of North Adelaide. They are back to back public courses that are used by walkers, golfers and, of course, the occasional wildlife photographer.

My morning walk started around eight and my quarry was the various groups of cockatoos that I had noticed feeding on the fairways earlier in the week. Although the birds are up and about just after dawn the light is not really conducive to capturing quality images in the early hours. As I strolled past the clubhouse towards one of the greens near the end of the course I heard the unmistakeable chatter of galahs (rose-breasted cockatoos). A quick glance around the area and I discovered half a dozen birds in a nearby patch of rough using their powerful, curved beaks to dig out tubers and crack open fallen seeds.

After a few minutes I left the cockies to their morning meal and moved across the course to a stand of tall, pale Eucalypts. As I scanned the canopy for movement several of the feeding birds flew onto a branch and started to groom each other. This was an unusual behaviour that I had not previously observed in galahs though I am sure these gregarious parrots interact socially in many ways. Perhaps they were a nesting pair and an older offspring. The grooming continued for a few minutes then escalated into a good natured session of sparring with beaks and wings that looked remarkably like a wrestling match.

My final cockatoo encounter was with a small group of little corellas near the car parking area. They were using their powerful beaks and claws to break up pine cones and extract the seeds. The birds seemed oblivious to me as they worked away at their hard won meal and I was able to sit and watch them for some time.
