Port Germein’s Mangrove Wildlife

1 Aug

Port Germein’s Mangrove Wildlife

Dear Reader:

 The grey butcherbird is perched on a dead branch on the edge of the mangrove swamp. The powerful bird will use this position to dive on prey in the undergrowth snatching up insects, small reptiles and the nestlings of other birds. Large prey will be jammed in the fork of a branch then eaten; which provides a hint as to how butcher birds acquired their name.

It is sunset and the light is glorious as it defines the mangrove channels against the pale sand. I am on the northern side of Port Germein where a substantial stand of mangroves merges with the shallow beach. Small schools of fish are heading along these waterways towards the ocean as the tide recedes and an odd crab scuttles across the channel.

 

Lovely light

 

 

As I climb back into the 4WD I can hear the calls of several different kinds of honeyeaters in the nearby scrub. With the windows open I drive slowly along the rutted trail until one of the little birds appears in the upper branches of the bushes. Several frames later I have captured a passable image of a spiny cheeked honeyeater calling to its mate. Often shooting from the vehicle is easier as the wildlife seems more accepting of its presence than that of a large two legged creature stalking through the bush.

The next morning I walk in the opposite direction to explore a channel that runs parallel to the shore on the southern perimeter of the township with a spectacular view of the Flinders ranges in the background. There are mangroves and samphire right to the edge of the creek which ends in a dilapidated road bridge that once serviced a crossing into town. A white faced heron is sitting on the weathered planks eyeing the water below for small fish while swallows are nesting under the main span.

As I make my way alongside the waterway I notice silken sheet like webs, carpeting the ground between many of the bushes. Some are still glistening from the morning dew. They are used by lattice webbed spiders as a kind of horizontal trap that acts like a sticky labyrinth.

With my mangrove walk completed, I head back into town for a bite at the local cafe. But Port Germein has on last wildlife moment to offer in the form of a wattlebird feeding on some late blooming eucalyptus flowers near the caravan park.

Footnote

4WD is useful in this area and the walking on the southern edge of town is quite strenuous. The northern reach of mangroves would be suitable for a family or seniors’ excursion.

Apex Park….. A noisy walk on an autumn evening

Apex Park….. A noisy walk on an autumn evening

 Dear Reader:

I can hear the bird chirping deep in the reeds that surround the waterway. Pointing the long lens towards the sound I scan the thick tangle of bulrushes; nothing! Then I catch the slightest movement deeper in, closer to the water. Success, I squeeze the shutter release and smile inwardly. Reed warblers are hard to see at the best of times and this is only the second image I have captured. Reviewing it on the screen I notice that the bird has its beak open. ‘Yes’, my reed warbler is warbling.

I am walking around a lovely little wetland called Apex Park, just off Sir Donald Bradman Drive near the airport. Having grabbed a bite to eat at the Ikea store, along with a few items for my studio, I have parked in alongside the little pond and am taking a slow walk around the tracks and boardwalks that surround it.

 

General view

 

Viewing platform

My next stop is a viewing platform close to a long dead tree that seems to be providing a good vantage point for a cormorant and several resting swallows. As I steady the camera a young willie wagtail lands on a skeletal branch and starts to sing. It seems to be a day for birdsong; nice theme for a series of images.

Geese

And the world of bird acoustics does not seem to be letting up. A pair of geese cruise across the water honking as they paddle and the musk lorikeets high in a eucalypt by the water’s edge are making ‘one hell of a racket’.

 

Galahs

 

When I get back to my starting point I sit alongside the pond and enjoy a moments silence, and it is a moment for right on cue a pair of galahs start to squabble over a nesting hole.

Additional information

This is quite a short walk with no steep gradients. There are toilets, a playground, benches and shelter in the vicinity.

Port Gawler

Port Gawler

Dear Reader:

The road from highway one to Port Gawler has a rural feel about it. There are crops and glasshouses, sheep and horses. At the same time the flowering gums punctuate the grassy verge attracting a range of parrots.

a

Curious horses

 

Several kilometres pass and I notice the terrain start to change. Pasture gives way to low coastal scrub and tidal channels appear alongside the road. The bird life changes too. Herons, ibises, sandpipers and plovers replace the woodland and urban species I have been observing.

b

Galah

 

Finally the scrub gives way to mangroves and the dense ticket of maritime trees stretch all the way to the nearby ocean. I can hear singing honeyeaters foraging in the foliage and a plethora of insects buzz between the tangled trunks and muddy substrate.

Great egret

 

The road is now unsealed and it ends at an old ruined wharf where weathered jetty poles protrude from the water. A little pied cormorant perches on one of them surveying its hunting zone while drying its wings in the sun.

Mud life

 

I spend the next few minutes exploring the edge of the mangrove swamp watching for mangrove crabs and small molluscs that live around the strange root like protrusions that emerge from mud throughout the forest. They are called pneumatophores and help the trees breathe in the sticky anaerobic mud.

The temperature starts to climb and I decide it’s time to head back home while a solitary nankeen kestrel hovers over this fascinating tidal wetland watching me drive back to the highway.

 Additional notes

This is an easy drive and walk which is suitable for families and seniors. However there are no nearby public facilities.

It is also a conservation park with restrictions regarding pets, fires and other activities…check online.

Naturally Bonython Park

Naturally Bonython Park

Dear Reader

There are two rainbow lorikeets perched halfway up a red gum. They are exploring a potential nesting hole. First one bird pokes its head in then the other. Their house hunting is accompanied by much squawking, head bobbing and an occasional nip at each other. Just when they seem to have decided that this is the right site, a magpie lands on the branch just above them and both parrots take flight.

Rainbow lorikeets at nesting hole

 

I am in Bonython Park by the Torrens River; downstream from the weir and opposite the Coca Cola factory on Port Road. Below me cycle and walking trails surround the waterway and a small causeway and larger train bridge cut across the river. The park abuts the holding paddocks for the police greys by the old jail and includes wide expanses of green space, a shallow paddling lake, kiosk and children’s playgrounds.

2-bonyth-red

Bonython Park Kiosk

 

 

From the recreational area I walk down to the pathway then head back upstream towards the train-bridge and city. The river bank is cloaked in tall reed beds and I can hear numerous small birds moving and calling in the jungle of stalks and leaves. There are several grassy areas that are free from the reeds and they provide opportune places to sit and observe the river’s wildlife.

3-bonyth-red

Purple swamp hen

 

Coots, moorhens and purple swamp hens are common along this stretch of water. The coots and moorhens tend to be in the water paddling close to the cover of the reeds. The swamp hens are more often seen in amongst the tangle of plants by the bank where they use their elongated feet to walk gingerly on the fallen reeds that form a mat on the water’s surface.

Downstream view from railway bridge

 

The view from the bridge to the ford provides a good oversight of the river and eucalyptus trees that line the banks. However, the bridge is also a perfect shelter for a number of different animals. Over the years I have watched water rats foraging here and even a fox that was taking shelter during a rain storm. Today it is an eastern water skink that makes an appearance as it forages amongst the old wooden foundations of a pathway that runs under the bridge.

5-bonyth-red

Downstream from the bridge there are several islets made from debris that has floated down the river during recent floods. Several pelicans have claimed this territory as a resting place and are squabbling over squatters’ rights. They duel with their beaks, neither giving way, while disturbing a group of black cormorants that are using the same area.

6-bonyth-red

Pelican agro

 

I am almost back to where I started when I find one last target for my camera. Two swallows are perching on a papyrus stem where they are making forays over the water to hawk insects. Swallows are not the easiest birds to photograph as they are incessantly on the move but this pair has cooperated even though they are still at the extreme range of my equipment.

Modbury’s Three Bridge Walk

1 Aug

Modbury’s Three Bridge Walk

 Dear Reader:

There are ibises along the banks of the pond and high in a river gum. One pair seems to be concentrating on a particularly dense area in the crown of the tree. I look more closely through the telephoto lens. It is a nest, barely discernible amongst branches. Closer inspection reveals a pair of chicks nestled against one of the parents while the other has left in search.

1

Ibis nest camouflaged in gum tree

 

I am walking along the pathway that runs from Montague Road to McIntyre Road behind the little complex of shops that includes Katmandu, Bunnings and Subway; just a few hundred metres before TTP. It is best to park next to the creek appropriately behind the outdoor shop then walked over a small traffic bridge to Victoria road. After a hundred metres, head left over the footbridge that crosses Dry Creek past a large pond where the ibises gather.

Walking and cycling track along Dry Creek

 

Leaving the ibises to their domestic duties I follow the creek using a small track along the bank. Alternatively a new concrete path traverses the same route. There are waterfowl along the creek which is flowing quite fast after heavy winter rains. In a slightly calmer stretch where a curve in the creek creates a sheltered pool a pair of black ducks, recognisable only by their upturned tails, are feeding on the bottom.

Along the secluded detour

 

After a couple of hundred meters I come to the third bridge which crosses the creek and bends back to the car park and lunch. However, alongside the bridge there is another rough dirt track that leads into the scrub emerging at a lovely secluded section of the creek. As I follow this trail I come across a variety of smaller birds including some New Holland honeyeaters that are perched in the reeds and a flock of musk lorikeets squawking high in a huge red gum near the trail junction.

I back track to the bridge, cross it, turn left following the main watercourse and stop to photograph a small waterfall that has developed in the creek. From here the track branches left running alongside a steep banked gully with very little water in it. Back at the car park I can get some lunch, shop for outdoor gear or find some hardware to occupy the remainder of the day.

A Walk in the Botanic Gardens

17 Jun

Dear Reader:

Australian magpies are fascinating birds, gregarious and intelligent with rather an aggressive streak during the nesting season. This one seems a little out of tune to the seasons, it’s not really the time to be constructing a nest at the beginning of winter but here it is collecting material for just that purpose.

Botanical gardens are wonderful places to observe wildlife especially in the winter months when some animals’ natural habitats can be bereft of food while others will have moved on to the proverbial ‘ greener pastures’. The incredible variety of plants in the gardens ensures that something is always flowering or fruiting which in turn leads to a food web that supports a range of wildlife from birds and mammals to insects and spiders.

 

1 2

Photographer at work

 

Our Botanical Gardens also draws in another species; the nature photographer (Homo sapiens cameralis) and they often migrate great distances to enjoy our wildlife. The gentleman in the picture was a visitor from Asia who was keen to photograph Australian native plants and we had an interesting conversation about the unique ecosystems that he might visit in South Australia.

 

1 4 1

The lake near the kiosk and restaurant

 

My excursions often include a place to eat and have a break and there are several in the Botanic Gardens. On this occasion I simply sat by the quaint little lake and enjoyed a light snack from the kiosk but more elaborate and substantial meals are available from Cafe Fibonacci and the Botanic Gardens Restaurant. The gardens also house a museum of economic botany, Victorian era palm house, the bicentennial conservatory and many other specialised areas.

 

1 4 2

Eastern rosella

 

Walking around the lake is always a pleasure and in the warmer months giant carp feed near the banks and freshwater turtles are commonly seen basking on the surface. Today, there are several cormorants drying their wings and a lone rosella foraging for seeds amongst the bare limbs of a tree that sits on a small island in the lake.

Maned ducks feeding near the creek

 

From the lake I head east towards the Bicentennial Conservatory crossing over a small creek where a pair of maned ducks and a crested pigeon are foraging in the lush grass that borders the waterway.

Self portrait in glass

 

My last encounter is with another one of those hominid species that frequent the gardens. Indeed, it is my own reflection as I pause to photograph the fascinating glass sculpture entitled ‘Cascade’ by Australian artist Sergio Redegalli,  which dominates the southern end of the conservatory.

Barker Inlet and Greenfields Wetlands …a road trip

23 Feb

Barker Inlet and Greenfields Wetlands ….a road trip

Dear Reader:

As I cruise along the highway between Port Adelaide and Salisbury a succession of lagoons, ponds and wetlands flash past my windscreen. Over the last couple of decades this once industrial wasteland has become a haven for wildlife and an integral part of the system converting run off into clean water that flows back into the ocean.

1Torrens Island power station

Torrens island power station looms behind the wetlands

 

There are several parking bays along the way that provide vantage points and access to walking paths into the wetlands. In rather an anomalous environmental scene the first one that I explore has the Torrens Island Power Station as a backdrop. And, a family of maned ducks are sheltering amongst the reeds in the foreground.

2

Maned ducks

 

I drive another couple of kilometres to a large siding where two 4WD vehicles with council logos on them are parked by a path into the wetlands. A small group of volunteers are working on clearing weeds, counting bird species and making other environmental observations about the health of the ecosystem.

3

Those who care

 

Leaving the voluntary workers to their work I find the next promising entrance and park my car. A sign indicates that we have moved into the Greenfields Wetlands. The track leads to an old bridge then follows an embankment along the edge of a small lake. The twittering of wrens provides a constant sound track as I scan for water fowl and reptiles along the edge of the reeds. There are coots, swamp hens and Pacific black ducks as well as turtles and water skinks along this section of wetland but it is a glorious little blue wren draws the attention of my long lens.

4 2

Male superb blue wren

 

The watercourse ends in a sluice gate that regulates water flow between the ponds and on one side I can see the swirl and splash of large fish feeding in the shallows. They are carp, an unwelcome guest in any ecosystem and their eradication is probably another task for the council and other environmental protection agencies that watch over these important resources.

5

Carp feeding in the shallows

 

My final stop, just before the salt pans is particularly fruitful as there is a mixed population of black swans, herons and spoonbills feeding in a shallow lagoon. It is always interesting to observe these quite diverse species with their individual feeding styles and uniquely evolved body parts. Their beaks, legs and feet have developed unique characteristics over time for feeding in the same area but utilising different food sources and therefore not competing.

6

A mixed group of waterbirds

 

And, as is so often the case, my thoughts also turn to food. The Watershed Cafe, just over the bridge, is opportunely positioned on another part of the Greenfields system near Mawson Lakes. Sitting on the edge of a reed fringed lake it is the perfect place for coffee and cake at the end of my wetlands drive.
