A Hot Semaphore Sunday

4 Mar

A Hot Semaphore Sunday

Dear Reader:

As I walk along the Semaphore jetty I can see several anglers working the shallows for silver whiting. Further along, another fisherman is jigging for squid. His bucket is half full of small baitfish and an opportunistic silver gull is sitting on the railing eying the contents as breakfast. The angler is unaware of his feathery adversary and a few minutes later the gull grabs a fish and heads off down the jetty.

Semaphore is one of Adelaide’s original coastal suburbs and the jetty has been part of Adelaide’s beach scene for well over 100 years. It was originally used to moor pilot and customs craft. A coastal pathway follows the beachfront behind the dunes allowing visitors partial access to this protected area of sensitive coastal vegetation. The Esplanade, near the start of the jetty, is dominated by the iconic Palais Restaurant and Function Centre which was built in 1922. This Semaphore landmark has served as a bathing pavilion, dance hall, surf life saving club and kiosk before renovations in the 1990s.

Closer to the shore a young Pacific gull sits on a lighting fixture watching the antics of its smaller cousins and keeping a watchful eye on the ocean ready to patrol the shoreline in search of its next meal.

It is getting warm by the time I walk off jetty on to the beach where I have left some snorkelling gear with a family who are enjoying the solitude of an early morning dip. The water is clear and there is little tidal movement as I enter from the beach. I follow the jetty poles out to sea as they provide shelter and food for a diverse collection of marine animals. It is not long before I notice a large blue swimming crab foraging near the bottom. We play a game of tag around the pole as the aggressive crustacean uses its powerful pincers to keep me at a distance.

Half an hour in the water is enough to cool me off and I still want to walk along the pathway to search for birds and reptiles in the dunes before it gets too hot. Most of the bird life has sought shelter from the sun but I do encounter one singing honeyeater amongst the grasses that bind the loose sand of the dunes. Along one of the trails to the beach, a sleepy lizard emerges from under a coastal acacia bush to eye me suspiciously before disappearing amongst the ground cover.

Over the next half hour I stroll down couple more paths and sit quietly amongst some of the coastal scrub watching for tell tale signs of animal life. Numerous doves peck amongst the ground covers and a group of wattle birds squabble noisily in one of the larger shrubs. However, as midday approaches the sun and heat has obviously taken its toll on both me and the wildlife and it is time for a cold drink and lunch. Needless to say, the Palais adequately provides both and as I look across the dunes from my table by the window, enjoying a delicate dessert, I reflect on how much I always enjoy my visits to Semaphore.

What more do I need to say

Port Germein ….A Long Walk Out to Sea…Field Notes

8 Mar

General description of location

Port Germein is a  small country town just north of Port Pirie which is  a major regional centre about 2½ hours from Adelaide

Lies near the top of Spencer Gulf and is in the shadow of the Southern Flinders Ranges.

Town has a pub with excellent food, a general store and campground

Small local population of around 250

A long jetty, once used to load grain clippers, it extends from the shore to over a mile out to sea and most of the beach is exposed at low tide

Good fishing, crabbing and general coastal wildlife walks

6 jetty and ranges red

View back to the ranges from the end of the jetty

Notes

Season:

Late summer

Weather:

Mild morning temperature around 18 ºC at 0900.

Forecast temperature 35°C later in the day

No wind and clear skies

5 blue bee red

While walking from the house where I am staying to the jetty I spot some blue bees, an Australian native species, feeding on a coastal bushes with small blue flowers

They tend to feed on blue and white blossoms

Note to self

Identify some of the coastal vegetation before next PT Germein post

I stroll along the jetty and notice a variety of small wading birds feeding on the sand/mud flats, some are searching out small pools of residual water

A young couple near the end of the jetty are crabbing and they have caught half a dozen Blue Swimmer Crabs which are common at this time of year

A group of Pied Cormorants and Common Terns are perching on some battered poles which remind us that the jetty was once longer

A family have used a tractor to tow out a small boat and launch it as the tide comes in

The view from the end of the jetty of the foreshore and Ranges is spectacular.

I return to the shore and walk along coastal path that weaves between low bushes and stretches of beach

There are honeyeaters and finches in the bushes and a Ring Necked Parrot preens itself on a branch

Near a rocky outcrop close to a garden I come across a Bearded Dragon sunning itself

There are also quite a few White Plumed Honey Eaters feeding on blossoms in Eucalypt trees that grow in gardens near the coastal walk

After sipping nectar some are hawking for insects.

A ten minute walk from the end of town, the coastal scrub and samphire give way to stands of mangrove and a whole new coastal ecology emerges

A White Faced Herons stalk small fish and crustacean in the shallow channels and a White Browed babbler fluffs up its feathers in one of the mangrove trees

These mangroves are part of a south Australian system that marks the southernmost extent of mangrove communities in the world

Small fish can be seen schooling in some of the deeper channels

This is a nursery area for many commercial species.

I head back to town for a schnitzel and a beer at the local pub and the promise of a drive to Telowie or Port Germein Gorge in the afternoon to look for rock wallabies and eagles.
