Dry Creek by the Junction

31 May

Dry Creek by the Junction

Dear Reader:

Yes, an ant is an ant, but in Australia some ants are just that little bit more! Inch ants or bulldog ants live up to their name and reputation. Solitary hunters that still live in communal nests they have a fearsome bite and relentless disposition. This one is hunting late on a cool autumn afternoon scouring a eucalypt trunk for prey. I watch carefully as it systematically probes under the bark for any hapless invertebrate that is sheltering or hibernating. Seeing a bulldog ant at this time of year seems strange, perhaps a late burst of warm weather woke the colony up. The vagaries of nature are always fascinating.

I am exploring the section of Dry Creek which flows between the intersection of Grand Junction Road and Nelson Road through to Walkley’s Road. It can be accessed behind ‘The Junction’ shopping centre. The creek twist and turns along this part of its length and is bordered by walking and bike trails. There are some deep pools, a ford and a small footbridge which all facilitate wildlife viewing and photography. Throw in a nice bakery at the shopping area and you have the makings of a perfect walk.

The little footbridge which spans the river is an ideal place to watch for wildlife. It is high on the banks and provides a good vantage point for peering into the treetops. Today it is the surface of the water that catches my attention. The tell-tale V shaped ripples of a water rat swimming across the creek are an unexpected bonus on my walk. I have rarely seen the elusive little rodents in Dry Creek and to know that they are present is quite a treat. Water rats or rakalis are a native species with a broad head, webbed feet and a white tip to the tail. They feed on aquatic insects, yabbies, molluscs, frogs and small fish.

Further along the path there is a break in the bushes and trees that envelop the sides of the creek and I can get good access to the water’s edge.  A little pied cormorant is sitting on a log directing its gaze into a long pool before continuing to hunt amongst the reeds along the water’s edge. On my walk back I see the same bird with its wings outstretched drying them between forays into the creek to hunt. Cormorants do not have waterproofing oils to protect their plumage like some waterbirds and therefore must continually dry out their feathers.

Near one of the fords there are some massive river red gums shading the creek bed and I can hear the raucous screech of lorikeets in the highest branches. A quick look through the telephoto lens helps me to identify them as musk lorikeets. These social little birds seem to have found something to feed on in the canopy. There are no blossoms on the trees so I can only assume that it is some form of insect life.

My walk has been most rewarding as I have encountered a wide range of animals from aquatic mammals and predatory insects through to brightly coloured parrots in the treetops. Only the bakery to go and I can mark today down as more than a little successful.

Additional notes

This is an easy walk which is quite suitable for families and seniors with food outlets, parking and other facilities nearby.

Cape Jervis as a wildlife destination

2 May

Cape Jervis

Dear Reader: 

Cape Jervis is a rugged promontory at the southern tip of the Fleurieu Peninsula overlooking Backstair’s Passage. It lies about 110 kms south of Adelaide along South Road. The little township is a fishing community with a lighthouse and the terminal for the Kangaroo Island ferry. The location was named by Matthew Flinders after John Jervis; a seaman who rose to the rank ‘Lord of the Admiralty’.

The drive into Cape Jervis passes by open farmland and patches of scrub where there are often kangaroos grazing sometimes alongside sheep. Crows, magpies, rosellas and many smaller bird species including wrens live in the natural vegetation along with a variety of insects and reptiles.  Occasionally wedge tailed eagles are seen circling on thermals searching for prey.

The shoreline is strewn with pebbles and jagged outcrops of rock creating numerous rock pools. This intertidal zone is the habitat of numerous invertebrate species such as; crabs, anemones, sea snails, limpets and shrimps. Wading birds including oystercatchers, plovers and herons feed in this zone as well as gulls. Cormorants can often be seen drying their wings on the rocks.

Below the water the rocky shoreline is dominated by brown algae and silver drummer, sea sweep, kelp fish, morwong and parrot fish are just a few of the many fish species that live in the shallow margin close to shore.

Further notes and comments:

  • Snorkelling along the foreshore requires care as the rocks are sharp and entry to the water can be difficult. There is also a strong rip current running parallel to the shoreline so stay in shallow water.
  • A pathway runs from the lighthouse to the beach front
  • There are snacks for sale and public toilets at the terminal
  • A variety of fish can be caught in this area from the shore and boats
  • There is a public boat ramp
  • Charter fishing excursions can be arranged from Cape Jervis
  • The lookout on the left hand side entering the town provides sweeping views of Backstairs Passage and Kangaroo Island
  • Southern right whales and dolphins are sometimes spotted in Backstairs Passage
  • The Heysen Trail walk that goes all the way to the Flinders ranges begins here
