Sex, nests and dog fighting

The sparrowhawks are back!  And they’re ready to make babies.  How do I know?… well (ahem)… I’ve been watching. But not taking photos. No, that would be weird.

That said, I have captured the occasional intimate post-coital moment. It seems raptors don’t have a cigarette after coupling – they gnaw on raw flesh and collect sticks.  All in all, probably healthier options.

Watching the pair collecting twigs to renovate the nest in the neighbour’s pine tree has been quite entertaining.  Collared sparrowhawks are such poised and elegant birds.  But with their finely built frame and long delicate claws they’re not natural construction workers.  Their technique seems to be to find some dead branches and leap awkwardly around on them hoping for the best, with a bit of light gnawing thrown in for good measure.

And whatever the sparrowhawks are trying to do, the pied currawongs are hanging around trying to stop them doing it.

It didn’t really surprise me to see a gang of six or seven currawongs loitering threateningly while a sparrowhawk tried to pluck and eat their breakfast.  I’ve seen the hawks move from tree to tree two or three times trying to get a few minutes without harassment.  But why would currawongs want to disrupt nest building? Especially when I’m pretty sure at least one or two of them got take-away chick from that very same nest last summer.

Nevertheless, the sparrowhawks have persisted, chasing off the currawongs whenever they can and fleeing them when necessary.  Aerial dogfights are a regular feature around here at the moment –  the hawks chasing away cockies and king parrots;  currawongs divebombing magpies and hawks; and of course me legging it after everything feathered with my camera. Not that the sparrowhawks seem to care about the activities of the humans down below.  All the critical action is happening in the canopy or the sky.

A first glimpse of the sparrowhawks

From battery to backyard

I’ve been following the activities of our local battery-hen rescuers – Let the Ladies Go – for a while.  Every few months they take a couple of thousand chickens from a local chicken farmer.  ISA browns lay like machines for a couple of years and then their fecundity tails off a bit – egg producers want to get new, younger hens at this stage.  The farmers who supply Let the Ladies Go choose to hand the older chickens over rather than slaughter them.

We’d been thinking about taking some rescue hens for some time, and when Let the Ladies Go sent out an urgent call for help on a sunny weekend when we had no commitments, we took a drive to beautiful rural Cooranbong with a big ventilated cardboard box.

The horde of rescued chickens seemed pretty happy wandering around their giant holding pen in the bush, but the logistics of feeding and caring for thousands of chickens must be mindboggling.  The rescuers take the really sick and injured chickens – the paralysed, the totally featherless, the partially blind – indoors to nurse them back to health (with the help of hand-knitted chicken jumpers and chicken nappy pads).   So our girls, like all the others in the yard, were surprisingly healthy, if only patchily feathered and with slightly clipped beaks.  We planned to take a pair of chooks home but in the end got talked into taking three, thinking that if one pegged out, the two remaining girls would still have each other for company.  But all three chooks – Ruff, Crumpet and Dusty – have made it (so far, anyway).

When they first arrived the girls’ experiences of captivity were pretty visible.  I was too disorganised to have their enclosure totally sorted, so when we got back from our drive we plonked their cardboard box, top open, in the yard, while I got creative in my favoured artistic medium – zipties and bamboo.  All three of the girls were quite capable of flapping out of their box, but they sat tight for an hour, scarcely noticing that escape was an option.  Which was lucky in a way.  We wanted to keep our existing chooks physically separated from the new girls for a week or two – although they could suss each other out through the chicken wire fence – until the rescue hens built up their strength.

Over the next fortnight we got to see them learn about the outdoors: the taste of sweetcorn, autumn leaves underfoot, the touch of sun on their feathers.

Eventually, feeling more confident that the rescue chooks weren’t bringing disease to the backyard, we let the two flocks mingle. The new girls weren’t entirely happy to find that their bucolic patch in the sunniest part of the garden was a favoured hang-out of the incumbent chooks as well.  In particular, Winter the leghorn, low on the established pecking order, proved to be tyrant.  “Winter is coming” …. something strike fear into the heart of an ex-battery hen.

Needless to say, there were ructions when we decided it was time to move all the hens into Colditz, our predator proof cage, recently upgraded with a light-sensitive automatic door.  Because chickens are up with the sun, but these humans generally prefer not to be.

Winter was not happy about the girls moving in on her territory.  The new automatic door – the world’s slowest and bluntest guillotine – starts shutting when as lumens drop to single digits.  The new girls make an effort to get into the cage as the darkness began to gather but Winter stands, beady eyed, by the door.  The minute she turns round to head to her roosting quarters, though, they’re in like a shot.

The rescue chooks have settled in now, with only the occasional bit of light argy-bargy.  The new girls are even laying eggs – with the lengthening days, we’ve just started being able to give our neighbours the occasional half-dozen.  But more to the point, the rescue hens are really charming.  They seem quite egalitarian – they get on well as a threesome, and there’s minimal aggro between the three of them and our other chooks.  They’re curious and interested in investigating the world around them.  And they like people.  When I’m down in the garden, they loiter nearby, expecting all of the good stuff.  They’re much more sociable than the chickens we’ve looked after since they were week old balls of fluff – well, except for the loveable Apricot.

It seems strange that animals who have been treated, on the whole, quite badly by human beings nonetheless expect fine things from us.  Maybe there’s hope for us after all.

The Great War and rubbish

Hole pattern abstract

There’s nothing I like better than a scene of elegant industrial decay.  Place that ruin-porn in the tranquillity of the Hawkesbury at midwinter.  What could be finer than a paddle around a rusted out wreck on a still morning, in the company of breakfasting eagles and kites?

What surprised me, back on land, when I dug around to find out more, was the age of this beautiful ruin.  The Parramatta was the very first ship commissioned for the newly formed Australian Navy after Federation.  It was built in 1910, the first of six torpedo boat destroyers to be constructed by Fairfield Shipbuilding and Engineering in Glasgow.  The destroyer was part of the Australian Fleet in the Pacific during the Great War, hunting enemy ships up the Sepik River in New Guinea, patrolling the waters around the Phillipines, Malayan and the East Indies, and  later, battling submarines in the Mediterranean and the Adriatic.

The interior of the wreck of the Parramatta

It’s been a very long time since the Parramatta did what she was designed to do. She was taken off to be dismantled in 1929, when my granddad was a toddler.

But in her post-naval career, she’s certainly been reused a few times.   After being decommissioned, she was sold to the NSW Penal Department, along with her sister ship The Swan, and towed to Cowan Creek where each boat was to accommodate 50 convicts. The prisoners were supposed to work on a new road from Bobbin Head to Brooklyn that was to be “the finest marine drive in the whole world”.  The stretch from Windybanks to Bobbin Head was declared a detention area, but in the end, with a change of government and not a single vote in favour of the plan from the Kuring-gai Chase Trustees, the idea of building a road was shelved and the boats were sold again.  Their purchaser hoped (ultimately fruitlessly) to use them as a floating hotel for fishermen.  It’s rumoured they went on to house unemployed men and store water during the Depression, before being towed to the north end of Milson Island and used as a floating sand and gravel pit.

In the early 1970s, the historical significance of the wreck was began to be appreciated and the bow and stern of the ship were retrieved and preserved for posterity – the stern at Queens Wharf Reserve on the Parramatta River, and the bow at the Garden Island military base in Sydney.  Other bits have been less officially repurposed – all its valuable brass portholes, for instance, have been nicked.

It’s not really clear how the wreck ended up on a mudbank on a bend of the Hawkesbury.  It’s rumoured she and her sister ship The Swan were being towed downriver in a gale in 1934 when they broke away.   The Swan filled up with water and sank twenty metres deep in the river near Little Wobby public wharf, while the Parramatta was stranded in the shallow water amongst the oyster farms below Cascade Creek.

She’s not the only bit of flotsam and jetsam on that bend of the river, though, by a long shot.  I pulled in amongst the mangroves to stretch my legs below the waterfall, to find all manner of rubbish.  A discarded shopping bag was filled with drink bottles, polystyrene, coke cans, bait bags and the odd thong in a matter of minutes.  I even found a functional tupperware container and matching lid, some thing that I almost never see in my own kitchen cupboards.

I have no pictures of any of this trash, needless to say.  Unless it’s on the epic scale of Edward Burtynsky’s sublime depictions of industrial landscapes, utterly transformed by excavation and waste, our tide of plastic detritus is nowhere near as photogenic as the rusty bones of our military past.  But it will will last hundreds, if not thousands, of years longer.
