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.

Snake Island and Brisbane Water National Park

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.

A striated heron, one of the river side regulars, pretending to be a particularly striking bit of sandstone.

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.

Stingray Bay: lost and found

After years of denial, I have finally accepted that I’m a map hoarder.

Though my other half has long been known by the moniker “Map Man”, it’s me that whiles my evenings away at the Lands and Property Information’s map shop, and I’m the one who takes our topographic maps on most of their little outings on the water, snug inside their “Hercules” double zip-lock plastic bags.  There have been some unfortunate errors – we have a few maps of dull little patches of agricultural wasteland with a bit of barely navigable waterway in one corner.  But despite the ridiculously small slices of this wide brown land that can fit on any given 1:25000 map, they really are quite useful things.

Although possibly less useful – without a compass – in a white out.

Egg going into the mist

Setting out from Appletree Bay

Fog and mist are picturesque, right?  “In…mist, the picturesque artist can celebrate obscurity, lack of clarity, indistinctness, that which is veiled… the picturesque tourist is prepared to spend days in fog” (Murray, 2004, 874).  Or possibly, not so much prepared to spend days there as trapped there for indefinitely unable to find their way out, as you can see from the baroque twists and turns captured on my phone’s GPS on my last jaunt to Stingray Bay. I’m not sure why it didn’t occur to me to fish it out of its dry bag and consult it for directions!

I often laugh at the giant directional signs you see on the waters edge of the Hawkebury – they really look like they belong by a freeway, not a pristine riverside – but if it hadn’t been for a bloody great sign looming up through the fog, I might still have been floating aimlessly around Cowan Creek days later.

I was quite keen, back in April, leaving the boat ramp at Appletree Bay on a high and rising tide, to check out Stingray Bay. It’s a decent step – about sixteen ks, slightly more if you decide to do baffled pirouettes mid-stream – but not an epic yomp.  A trip up Smith’s Creek is a good one to do when the tide rising steadily rather than on the turn, since you can go with the flow on at least half the journey, and ride the current on last leg home.

I’d had a pit stop there at Stingray Bay before, on my way further up Smith’s Creek.  The Hawkesbury in these parts is a steep-sided sandstone gorge, flooded these last six thousand years with bottle green water, so this is a rare spot where you can get out of a canoe to stretch your legs.  You will most likely standing in knee deep water but that’s not so bad, unless you happen to step on the eponymous sting rays.  We worry more about sharks, but apparently after blue bottles, stingrays – most likely round these parts the common stingaree – cause the most injuries to beachgoers in Sydney.

They’re not aggressive animals.  Richard Wylie, a marine biologist from Monash University, described them as “wonderfully inquisitive and gentle marine animals“.  Stingrays give birth to live young and in Yolgnu communities in the far north, stingrays – specifically the mangrove whipray or Gawangalkmirri – were seen as devoted parents, the sort we humans should aspire to be.  And while I feel might fret about an encounter with a ray, indigenous communities have long seen them not as a threat but as an important and delicious food source.

But if you do happen to frighten stingrays – for instance, stomping on them while they’re hiding in the sand – you can get a sting from the toxin-bearing barb on their tail.  Apparently it hurts like hell. Immersing your feet in hot water denatures the toxin and takes the pain away, apparently, although a lot of people need pieces of barb removed from their wound and sometimes stitches and antibiotics too.

Seagrass and sand

Seagrass and sand in Stingray Bay

I’ve never stepped on a ray, though I have seen them, just once, in the shallows of Calabash Bay in Berowra Creek.  But just because you can’t see them, doesn’t mean they’re not there.  If you walk around in shallow estuarine waters, it’s best to have footwear and shuffle rather than stride.  Fortunately, my bum is usually so numb by the time I stumble out of my kayak that shuffling around stirring up the sand with my protective booties is not so much safety measure as a physical necessity.

I paddled straight over the sting-ray shallows, though, back in April, past yachts barely stirring in the morning mist and moody cormorants staring out at the post-apocalyptic blankness.

Even at half tide, you can skim safely above the seagrass and on up the creek.  There’s a deep swimming hole, and above it, two tiny waterfalls tumbling into a bowl of rocks.  Despite my morbid fear of breaking my precious and ancient wooden boat, I even managed to clamber out onto the rocks for a comfort break and a look around.  It’s a really lovely spot – a great place to come for a picnic and a splash around in warmer weather.

And not a bad place to hang out if you’re a baby fish either.  There may not have been any stingrays, but there were certainly plenty of little fishlings when I visited again, in very different weather, last weekend.  So very many fishies, swirling away from the paddle like living iron filings toyed with by slightly sadistic magnet… yet so surprisingly difficult for a bumbling amateur to photograph.

Stingray Bay certainly looks different (if possibly less picturesque) when you can actually see it.

Buoy with plain blue background

And the journey there and back again’s not too hard on the eyes either.  Except when you’re paddling straight into the morning sun.

The cormorants, the escarpment and the sun-touched tree tops might have been perfectly visible and, thanks to months with virtually no rain, the clear green water might have offered a vertiginous view of sandstone slabs sliding into the depths, but not all the mysteries of Cowan Creek were revealed to me on my paddle back to Apple Tree Bay.

Was it that persistent dive-bombing tern that plunked so heavily into the water behind me, leaving only a ripple by the time I spun around to see?  Did some underwater creature make that line of bubbles I paddled through on the way past Waratah Bay?  Could it have been dolphins?  Or more worryingly, a bullshark?  Maybe it’s better not to know.

But not while you’re navigating!

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”

Sea eagle at dawn long small

White bellied sea eagle at dawn over Spectacle Island

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.

Mother-of-millions takes to the waves

Mother of millions cabin close up crop small

You know a weed is a baddie when it will grow without dirt and entirely surrounded by salt water.  The Mother of Dragons inspires GoT fans and baby names but Mother-of-Millions – the stowaway on this attractively decrepit boat moored off Dangar Island in the Hawkesbury – inspires a deep and abiding hatred in bush regenerators, whose job is to try to get rid of weedy garden escapes like this one.

Mother-of-millions – a native of Madagascar – was imported to Australia in the 1950s as a drought tolerant garden plant.  It’s now a restricted invasive plant in Queensland, and can’t be given away, sold or released into the environment.  Here in coastal NSW and the northwest slopes and plains, it’s a declared noxious weed which means landowners (or in this case boat-owners) have a legal requirement to control it.  Like two-thirds of Australia’s noxious weeds, it’s a garden plant that got away.

To add to its charm, mother-of-millions (aka bryophyllum delagoense) is also toxic to humans, pets and livestock.  If animals eat enough of it (5 kilos for an adult cow) they quickly die with heart failure.  If they just have a snack, they’ll get bloody diahorrea, drool saliva, dribble urine and then die of heart failure.  Fortunately cattle are probably safe from this particular crop of bryophyllum.  Unless they are bovines with boats, or like a good swim.

You can pull mother-of-millions out by hand but it is, apparently, a soul destroying job.  The plant can reproduce from tiny seeds, dispersed both by wind and water – I’ve certainly seen colonies in bushland by Berowra Creek.  I hate to think how far and wide the seeds from this estuarine Typhoid Mary have spread.  The seeds remain dormant in the soil for ages, so getting rid of mother-of-millions is not a one-time-only job.  Like its toxic relative bryophyllum pinnate – the evocatively named resurrection plant – little plantlets growing on the leaves can also detach as you’re weeding.   Any tiny fragment of leaf can generate a new infestation.  You can spray it with herbicide, leave it in a black plastic bag to die, or hope for a visit from the (also introduced) South African Citrus Thrip which burrows through the leaves’ waxy coating to lay eggs on its flesh.  But none of this horticultural horror show works as well as setting it on fire.

We all have a biosecurity duty, of course: “any person… who knows (or ought to know) of any biosecurity risk, has a duty to ensure the risk is prevented, eliminated or minimised, so far as is reasonably practicable”.  And as a responsible gardener and card-carrying greenie, I take those duties seriously.  However I’m not sure the owner of this rickety vessel would embrace the idea of a passing kayaker with a molotov cocktail torching his boat, for all its mother of infestations.

The shortest days and how to use them

The chickens let us know when midwinter’s come.  The fortnight after the winter solstice, no matter how bloody cold it is, the girls start serious egg-laying.  So even as you’re trying desperately to stash four different kinds of hot lemon pickle and a hundredweight of lemon marmalade, as you open the fridge, a dozen eggs roll out.

I went AWOL from the blog for the last six months, as the observant amongst you might have noticed.  The days just got shorter and shorter.  My garden kept growing and the Hawkesbury streamed uninterrupted to the sea, but time to write about these things just seemed impossible to find.  But now the days are lengthening (and I’ve finished my night classes), all that is going to change!

Eagle flyby long crop

The shortest day may have passed but it’s still pretty nippy at 5.30 in the morning when I get out of my lovely warm bed and drive off through the nautical twilight to put my kayak in the water.  When it’s 3 degrees and you have wet feet, the exact moment when the sun touches your frozen toes comes to be of critical importance.

I have a nifty little app on my phone, SunCalc, that shows just where the sun will appear over the horizon on any day of the year.  So I check the tide, and the wind, and then, on a winter morning, figure out where I’ll catch the very first light.  Putting in at Brooklyn and heading for open water is not a bad choice.

I’ve had some lovely paddles from Parsley Bay in the last year.  Quiet jaunts into Porto Bay, a shallow backwater frequented mostly by raptors and oyster fishermen…

Juv sea eagle long

And, on a day with hardly any wind, I braved it across to West Head, stopping off at four beaches – Gunyah on the way and Eleanor on the way back; and on the other side of Cowan Creek, Little Pittwater with its tumbling stream and littoral rainforest and Hungry Beach and its a pair of sunbaking sea eagles.

I was almost bold enough that time to cross the invisible line – “limit of flatwater sailing” – that passes between Juno Point and Flint and Steel Beach, but bottled it in the end, just peeking round the corner towards Pittwater and the open Pacific beyond.

And last weekend, coldest it’s been on a Sydney morning in a couple of decades, I set out for Refuge Bay, where the pleasure craft rocked quietly, their skippers sleeping.  But not the kids, slipping away in their dinghies to fish and play under the waterfall on the beach.

And on journey there, what magic scenes!  The open waters of Broken Bay skimmed, concealed, curtained, framed, illuminated, by the fog.

Another sunrise, another paddle through a flooded river valley.  At Port Stephens the wide Karuah River meets the Myall as it meanders south, just behind the coastal dunes.

And where the water flowing from the network of wetlands and lagoons that is Myall Lakes joins the estuary, in a river delta protected from the destructive power of the Pacific waves, there’s Corrie Island.

A spot so fabulous for cautious amateur photographers in small and ancient boats, I circumnavigated it at the crack of dawn not once but twice over the silly season.  I may have been so exhausted I wept all over my Christmas crackers but it was worth it.

Just down the river from the RAMSAR protected wetlands at Myall Lakes, migratory birds that breed in the far north spend the arctic winters hanging out here.  I saw red knots (heads up: not very red in the non-breeding season) and grey tailed tattlers, far eastern curlews and bar tailed godwits.  In fact, I was treated to a bold dispay of the very barred tail of the bar tailed godwit, that tail that make the longest uninterrupted migration flight of any bird’s behind.

The eastern ospreys, in my previous experience elusive canopy lurkers, proved so indifferent to human proximity that I actually got bored with taking photos of them posing in the beautiful dawn light, and starting trying to snap the LBBs in the beachside brush, while the ospreys observed my inadequate efforts with golden eyes.

And just when you thought it couldn’t get any better, here come the dolphins.

The famous pod of Port Stephens dolphins – well, the easterly, sociable estuarine pod, one of two quite distinct groups that lives in the harbour – swung by to check me out.  I stopped still in the swell, watching them case the beach. At one point the still water by the boat upwelled and the tip of a bottle nose appeared above the surface for just a second or two a couple of metres off the bow.

A couple of mornings later, I was back, having rashly promised my birdwatching brother dolphins, ospreys and eagles.  No need for a refund: they arrived one after another, right on cue.

And in between boat trips, it wasn’t just overeating and board games either.  There was also watching the local bird life overeating.

7 degrees at daybreak and good company the evening before: no chance of making it out for dawn this weekend.  So it was the afternoon service for me in the Church of the Double-Bladed Paddle.  Down the end of our street, the Hawkesbury in the golden hour.

Beautiful cirrus sky and skyline

A seaplane was parked out front of the ritzy Berowra Waters Restaurant, a few devotees of fine dining lingering over white linen, but otherwise the river was quiet.  Weekenders emptied of their winter visitors, off home to find socks and check homework.  Some stirrings in the sandy creek bed – stingrays? – but no fishermen and hardly a fish.

Some sun worshippers were receiving the blessing of the last rays on the southern shores of Calabash Bay.

And then, a true glimpse of the sacred.  The sacred kingfisher, that is.  I’d suspected they might be found around here, even in the winter.  There was that green flash out of the corner of my eye as I scrambled over the rocks onto Bar Island, and the briefest of glimpses, framed by mangrove leaves, my camera hopelessly buried, one morning in Bujwa Bay.

But this glorious creature showed no inclination to move from his place in the sun, calmly accepting the adoration of passing paddlers.

But even a sacred kingfisher can be profane.  I’m reverently gazing, barely taking a breath, and the big guy takes the opportunity to have a lightning fast chunder.  There’s a  familiar doggo look on his face as he sits there on his sunlit stick recovering.

But you expect veneration anyway, right, mate?  And you’ll get it too.
