The river that knew

If I want a quiet morning on the Hawkesbury, my best bet is a paddle up Mooney Mooney Creek.  It’s a jet ski free zone, and that’s a very fine thing. In maybe ten jaunts on various reaches of Mooney Mooney, I’ve seen a handful of kayaks, a few fishermen and one very slow moving yacht.  Unlike Cowan Creek or Patonga, there’s no sandy beaches for frisking about on, and the oysterfarms can be navigational hazard at low tide. But if you prefer hanging out with eagles and herons to spending time with humans in charge of powerboats, Mooney Mooney Creek’s the go.

There are really three Mooney Mooneys, for my purposes anyway.  There’s the upper reaches, a pleasant morning’s paddle if you throw in tranquil tributary Flood Creek, lined with casuarinas and decorated with the blue and green streaks of kingfishers hunting (more on the scenes and ecosystems there in a future post).  The put-in for that trip is where the switchbacking Pacific Highway crosses the river, though if you paddle upstream you pass under the highest bridge in Australia, a symphony in soaring concrete.

Or you can go downstream, towards Lemon Tree Bay and maybe on a low-ish tide, see, on every bend and mudflat herons feasting, and if you’re lucky, spot a wedge-tailed eagle soaring overhead.

Up there in the headwaters, you’ll often see other kayakers – there are sometimes guided tours to the area – and occasionally people camping, rather naughtily, by the side of the river.  The Great North Walk, that links Sydney and Newcastle, via most of the lovely places along the way including Berowra (of course), flanks the upper reaches of the river and once or twice I’ve heard voices of hikers walking along the track or crossing the suspension bridge that spans the top of Piles Creek.

But I’d prefer to be paddling than driving and I’m a little bit lazy, so I usually put in my boat in closer to home, at Deerubbin, where the freeway crosses the Hawkesbury.  From there I paddle under the freeway and past Spectacle Island, stopping off to check out the Mooney Mooney spoonbill colony, and then upstream.  Once you get past Snake Island and Sailor’s Chest Point, there’s not much sign of human activity, apart from oyster poles.

But there’s plenty going on, even without too many of us humans around.  Last week’s outing was particularly rich in feathery encounters.  A masked lapwing family enjoying a day out by the water by the Mooney Mooney public wharf.

And further up the creek, the predictable but still wonderful sight of a pair of young sea eagles perched amongst the mangroves in the shallow waters of Fox Bay.

The young ones seem to be easier to get close to.  A bit curious and a bit clueless, perhaps, about strange legless creatures that float downstream with the tide.

Even in the peace and quiet, there’s a feeling that all the inhabitants of Mooney Mooney Creek know about us.  They know we’re there – mostly out of sight, maybe, but not entirely out of mind.  The freeway passes just behind the ridge much of the way up the valley. You see it as you pass Snake Island, the trucks and cars  appear briefly, lifted above the rocky escarpment.  Sometimes, further up the creek,  the wind shifts and you can hear the sound of the traffic.

I recently found out that the freeway’s original route went right through my tranquil paddling territory – along Pile Creek, to cross the river south of where the Pacific Highway runs.  Right through kingfisher country.

But someone in the National Parks and Wildlife Service in the late 60s or 70s stood up to the road builders and just said “No”.  No, you can’t build a bloody great big road right through the (then recently established) Brisbane Water National Park.  We’re not having it.  In the words of the surprisingly fascinating “OzRoads” website

This new route had a more expensive bridge and steeper grades than the preferred route but there was nothing the DMR could do about it.

And it’s not often you hear freeway builders say that.  I’d love to  know the full story of who in Parks fought the good fight with the Roads folk.  Everytime I paddle up Mooney Mooney Creek now, I’ll be thinking about them and saying a little thank you.

Meet the Royals

Spoonbill looking back good portrait 2 wideTo be honest, I’m a republican more than a monarchist, but over the weekend I met one set of royals I have some time for: Royal Spoonbills.  They carry off the ceremonial garb beautifully without raiding the public purse for grog or helicopter rides, and their landed estates are mostly mud, swamps and reed beds, as opposed to, say 20 million acres of Britain’s finest arable land.

Royal Spoonbills are not uncommon birds – their conservation status is secure across much of Australia, and they can be found not just in rivers and coastal mudflats but  also in temporary inland waterways during times of flood, wading through shallow water, feeling for fish, crustaceans and aquatic insects with their vibration-detecting spoon-shaped beaks. They’ve also made it to New Zealand, where their numbers seem to be increasing.

But I’ve only seen them on two occasions in my weekly outings on the Hawkesbury, at the same time – early morning an hour or two after low tide- and in the same spot, in the mangroves near the shambling boatyards in Mooney Mooney.  It’s place with a splendid outlook but it won’t be appearing on the front cover of Vogue’s Marina and Oysterfarm magazine.  Unless they’re doing a special spread on “2017’s best retro refits for your partially sunken houseboat”

The perpetually roar from the freeway, the piles of maritime junk and even the unchained dog wandering round the quayside didn’t seem to bother the herons, the pelicans or the spoonbills.  The tidal mudflats fringing Mooney Mooney and the nature reserve at Spectacle Island  across the way must make for good pickings, and the stands of mangroves by the boatyard a safe place to nest, over the water.

I’m pretty sure this is a regular hang-out for them.  Spoonbills living near the coast are sedentary and often use the same nests from year to year.  My failure to spot them over the intervening period is, I suspect, more to do with cluelessness about the best tide time to catch them, rather than a sign they wander around a lot.

Like darters, they breed in colonies with other waterbirds.  The first time I saw this group (or to use the proper collective noun, bowl) of spoonbills, in September last year, they were in the company of another wader I’ve rarely seen on the Hawkesbury, an egret. And this time, as well as the ubiquitous white-faced herons feeding en-masse on the mud flats at dawn and then later in the shallows, there were a flock of the much maligned white ibises – or “bin chickens” as urban Australian call them disparagingly – hunting in amongst the mangroves down the way.

Pelicans shouting at each other crop small

Apparently this is a male pelican (in breeding colours) chatting up a likely female!

I read that juvenile spoon bills have even been spotted grooming other species of waterbirds.  Shortsighted?  Or just very very friendly?

This time there was no sign of the spoonbills’ breeding plumage, a 20cm long crest of feathers on the back of the necks of both males and female (although the crest on female, like their legs and beak, is apparently shorter than the males’).  October to April is said to be the breeding season, so I must have caught them, last time, just before they paired up and started thinking about the next generation.  It’s probably lucky I didn’t catch them any later in the year, since it seems they’re very sensitive to disturbance when they’re on the nest.

Birds do seem to be more chilled around a photographer gliding along in a canoe than someone stumbling in the undergrowth with a camera.  It is pleasing to have this observation, made on the water over the past three years, confirmed by a recent paper, entertainingly called “Up the Creek with a Paddle”.  According to its authors, Hayley Glover, Patrick-Jean Guay and Michael Weston, the FID (flight-initiation-disturbance) distance of royal spoonbills is 23 metres if you are in a canoe, versus 55 metres if you’re on foot.  Mind you, driving up to birds in your car is also scientifically vindicated way of getting (slightly) closer to them before they make a break for it, but unless you want your SUV bobbing in the water next to the Mooney Mooney houseboat, perhaps not such a good idea in this instance.

Guay, Glover and Weston, having presumably spent quite some time running loudly (with a tape measure) through the reeds towards a range of species and then ramming them (carefully and scientifically) with canoes, recommend a “set back” from waterbirds for boaties of about 90 metres*. Which is a long way, even if you have a good zoom on your camera.  But I think, at least for the next few months, I’ll give the spoonbills a wide berth and let them raise their babies in peace.

Perhaps not a beautiful bird but certainly eye catching!

Two sad islands, three whistling kites

It’s 7 o’clock on a midwinter Sunday morning.  It’s five degrees C.  And I’m about to go canoeing.

The thought that I may be slightly mad has passed through my mind.  A key motivation for hauling myself out of bed before sunrise was to try to get a better look at the whistling kite that hurtled past me into the distance last time I put the kayak in at Mooney Mooney.  And as I’m standing in my innovative Milan-style long-johns and wetsuit combination, what do I spy, perched in a dead tree right above the car park, but a whistling kite, defrosting in the first light.  Tempting get that pic and hightail it back to bed.

But no, Bar Island is calling me.  I’m heading back to the spot where I first decided, on a boatie camping trip just up the river at Back Beaches, that my mental health demanded the purchase of a cheap canoe.  And halfway across the river, when the first rays of the morning sun hit me, I feel truly blessed.

Bearing in mind my favourite quote from Antonio Gramsci (“pessimism of the intellect, optimism of the will”), I started out my jaunt by heading across to Olga Bay. Last time I was there, a magnificent white bellied sea eagle swooped through the golden afternoon sunshine and snatched a fish from the briny right in front of the boat.

Unfortunately, convinced that the Hawkesbury was going to sweep me out to sea, at the time I had my head down, as I blasted my way across the river.  The David Attenborough moment passed while I was fumbling around in the dank reaches of the canoe for my much abused camera.

Needless to say, the sea eagle didn’t do a repeat performance, though that Australian darter that I pursued heartlessly from perch to desperate perch up the Wyong River last weekend had an unpleasant surprise on that therapeutic holiday to a little hire cottage on Milson’s Passage that the doctor ordered.

Bar Island greeted me with the green flash of (what I think was) a sacred kingfisher watching from the mangroves as I clambered awkwardly (camera-less, of course) over the slippery rocks to the shore.

To be honest, I found it a gloomy place, weighed down by history and hemmed in by trees.  They’re important trees – casuarina glauca for the glossy black cockatoos and red ash which, according to the informative signs, feeds the copper jewel butterfly.  Perhaps I’ve been living with a Scotsman too long.  I have started to share his culture’s love of denuded landscapes and the sweeping views created by sheep, deer and industrialisation. We’ve dubbed the accompanying fear of excessive greenery “wood psychosis”.  There was a bit of wood psychosis going on in Bar Island this weekend.

And then there’s visible colonial history of the place.  St John’s Church was built on Bar Island in the 1870s, and the grave stones of some of the sixty or so European settlers who are known to have been buried there remain, along with reminders of the troubled history of the Hawkesbury as a brutal contact zone.  “A difficult time” as the plaque commemorated Sarah “Granny” Lewis carefully puts it.

The best spot to be on Bar Island on a chilly winter morning was, not coincidentally, the wooden seat near the midden on the northern tip of the island.  The midden’s metres deep, accrued over thousands of years of shared oyster eating by Darug, Darkinjung and Guringai people, whose country meets here.

And not far away, the resident kite and her nest, were also basking in sunlight.  RB has been working here, on and off, for three years, and the nest has been there for at least that long, renovated and extended each season.  The kite wasn’t moving, despite the clumsy paddling and clicking camera.  It’s her island now, and she knows it.

I thought I was smart, timing my trip upstream with a rising tide.  I wasn’t feeling quite so clever heading downriver again as I tried to take a racing line across an sharp S bend, with the current and the tide battling it out all round me.

First I ploughed exceedingly slowly, on that perfectly still day, through a stretch of strange standing waves.  And then I found myself swirling through a sequence of weird vortices, that churned up silt and the occasional jelly blubber.  I read Lisa-ann Gershwin’s Stung! On Jellyfish Blooms and the Future of the Oceans a while ago.  She concludes, to put it bluntly, that we should enjoy fish while they last, as the jellyfish, floating around in the oceans since the pre-Cambrian, are on their way back with a vengeance, thanks to acidified, over-fertilised and over-fished oceans (not to mention climate change).

Since then I see every jellyfish as a portent of doom.  Given this slightly apocalyptic worldview, after about an hour and a half trying to escape this turbid hellhole (okay, it was about ten minutes) I began to worry that one of those whirlpools were going to suck me down into the bowels of the river, just the icefloes in this extremely spooky youtube find.

Needless to say, I survived The Whirlpool of Death.  In marked contrast to many of the people who went to live at Peat Island, which I paddled past on the last leg of my route home. Built to detox alcoholics early in the twentieth century, the site was used for over ninety years mainly as an asylum for people with mental illnesses or learning difficulties.  From all reports it was a horrifying place where inmates were caged, neglected and sexually abused.

The last residents, treated somewhat less brutally than those who came before, left in 2010, and the site is now padlocked and empty, awaiting redevelopment into a 250 berth marina and suite of five storey apartment blocks.  Because there’s nothing that says “high density living” and “brownfield site” like a place with national parks on all four sides.

I spotted one last whistling kite – in fact, a whistling kite actually whistling – in the Norfolk Pines on the island.   And in the distance, somewhere out of view, the elusive sea eagles, honking away like a pair of castrati ducks.  I know it’s sentimental in the light of these grim tales of the river, but I hope the birds are still there when the jet skiiers come to stay.
