Flying lawnmowers

There’s aren’t too many workplaces that have their own bird list.  Or offices that you can use as a hide for stalking coy marshbirds.

On the 5 k walk that bookends my train commute from Berowra to Epping, I might see a tree creeper or a figbird, a scrubwren or a fairy wren, a flock of silver-eyes or gerygones or red-browed finches, a eastern rosella or a crew of glossy black-cockatoos.  But the twitching doesn’t end when I arrive, because Macquarie University, where I work, is no mean place for bird watching either.

On occasion I’m asked to explain to prospective “customers” why they should study with us, rather than one of the other fine educational institutions in Sydney.  This kind of sales-pitch is not really my strong point – I’m a teacher, not a real-estate agent.  I find myself fatally drawn to talk, not so much about the passionate lecturers, the interdisciplinary subjects, the fancy technical facilities or even the light-drenched underground train station with tranquil majesty of a church, but mostly about the parrots.  Which, unfortunately, seems to be a niche interest from a teenaged point of view.

So when I found myself surrounded by maybe a hundred birds – magpies, swamp hens and miners mixing it with the galahs and cockies – on my walk home, I wasn’t too surprised.  But the long-billed corellas – their red slashed throats and preposterously dangerous looking beaks – were a new one on me.  For a start they aren’t meant to be in Sydney at all.

According to my bird book and the Michael Morecombe app on my phone, corellas are birds of the inland and the south. But for all that, there are plenty of of them around the cities of the eastern seaboard these days.  So very many in fact that in fact, a corella poisoner has been at work in the Central Coast, killing scores of birds from the flocks that roost in parks on the shores of Lake Macquarie.

So how did the corellas get to Sydney and Brisbane anyway?  One idea, as put about by Martyn Robinson from the Australian Museum, is that corellas moved east from the plains during the drought.  But even he agrees that flock numbers have swelled  – along with the wild birds’ English vocabulary – thanks to escapees from cages.  Long-billed corellas in particular are apparently wonderful talkers.

On the face of it, looking at the huge flocks creaking and wheeling over ovals and golfcourses, this sounds like an unlikely idea.  But tracking back through Trove, the wonderful searchable archive of Australian newspapers digitised by the National Library of Australia , it seems that corellas have been going rogue for a long time.

The first reference I find about these birds as pets in New South Wales is a story in 1878 in the Australia Town and Country Journal in about Mr D.E.Dargin bringing them 500 miles overland to join “collected goods of every sort” at the Bathurst Show.  And by 1879 we have the first Sydney corella reported missing:

It’s a fine thought – these long-lived, clever and social birds breaking out of their cages and joining their wild confederates.  My friend Rose has a beautiful story about a tame galah passed on to her after its previous human died.  She kept it in an aviary outside and most days a flock of wild galahs would land and spend some time on the grass nearby.  One bird in particular would always linger by the caged bird after the rest of the flock departed.

Eventually Rose decided to open the aviary door and let the two love birds fly off together into the sunset.  Galahs can live for up to eighty years, and while they form permanent pair bonds, they will find a new mate if their partner dies.  I like to think of the two of them out there somewhere, enjoying a late-life romance with a side serve of onion weed.

Some people – especially farmers – see corellas as pests. Apparently the long-billed species are a particular blight on ovals and golf courses, thanks to the six inch deep holes they can dig for roots and corms with their spectacular beak.  To be honest this habit endears them to me – there’s a fine radical history to the defacing of golf courses.

There was obviously good eating to be had last week on Macquarie’s sweeping lawns. I wonder, though, if the very oldest parrots that visit the campus still remember the finer pickings from the time, in the sixties, when it was all market gardens, orchards and chicken farms.

This is my argument for an active commute:

My view about halfway through my morning commute from deepest suburbia. Beats the back of the car in front, doesn’t it?  Okay, except if it’s this car:

As soon as we’ve had breakfast, fed the chickens and wasted a small but irreplaceable part of our lives looking for a missing shoe,  there’s the walk via school to the train station.  It’s a twenty five minute rail journey – just long enough to get depressed by the newspaper – and then the last three k on foot from Epping Station to Macquarie Uni.  I’m ashamed to say it took me several years to figure out that the cash I save on therapy by hoofing that last leg well and truly pays for the expended foot-leather.

I’ll admit, it’s a pleasant, if hilly walk, down leafy suburban streets and across the bridge at Terry’s Creek, a tributary of the Lane Cove River.  In fact, over time, I’ve come to feel rather attached to this spectacularly weed infested rivulet – I’m tempted to say it’s not Terry’s, it’s mine.

I think it would be fair to describe this waterway as a colourful year-long festival of invasive and noxious species, as you can see above. And I haven’t even included decorative photos of the willows, the trad or the waving walls of bamboo that line the way.  Terry’s Creek is so densely hemmed in and overhung by broad leafed privet that walking down the path towards Brown’s Waterhole feels like stepping into a suburban remake of Apocalypse Now.

What with the perpetual roar of Epping Road and welcoming ambience of the nearby electricity substation, your first thought wouldn’t be “valuable wildlife sanctuary”.  But in the 10 minutes I spend each morning and afternoon walking through through this part of Pembroke Park, a 500 metre strip of weeds and scrub, I’ve seen more small birds than I’ve seen over six years in beautiful Berowra, surrounded by national parks and with the freshest air in town.

The superb blue wrens, willie wagtails, red-browed finches and eastern spine bills are regulars.  My photographic evidence of the yellow thornbills and silver eyes consist of a sequence of butt-shots and blurry silhouettes – my white-browed scrubwren is only marginally better.  I’ve often been tempted to hunker down for an hour or two with a view to improving my collection of snaps but somehow I don’t think it would play well if I failed to rock up to my own lectures because I was busy with a long-lens camera behind a bush.

So there’s no proof I ever saw that startled pair of white-headed pigeons and or an eastern whipbird, the only one I’ve ever actually eyeballed. I suspect I snuck up on it, gallumphing footfalls obscured by traffic.  However, a few weeks back, I was dead chuffed to snap a very distant dollar bird having a rest in the overhead powerlines.

But according to a habitat survey from a few years back, there’s still loads of locals I haven’t seen.  Pardelotes!!  Powerful owls!! Someone bring the smelling salts!

I’m not quite sure why this is such a good spot for LBBs (and LRBBs – little red and brown birds, LBBBs – little blue and brown birds, LYBBs etcetcetc). There’s the creek of course, and the lantana and the privet berries, and the tangle of bamboos and morning glories to hide in – weedy or not, the kind of dense multilayered cover that small birds need to survive, as this beautifully specific guide by the Habitat network points out.

There’s also plenty of native grasses, vines and trees, some quite recently planted, many pleasingly photogenic but also lots of the kind of spiky unglamorous bushes that are favoured by smaller birds as hide-outs –  kunzea ambigua, for instance.  This part of Pembroke Park, scrubby and not at all fun to bushbash through, is part of a line of green spaces stretching north to Lane Cove National ParkSmall birds need such “stepping stones” – contiguous patches of cover – to flourish.

The wrens and finches seem to particularly enjoy the grassy area a wee bit back from the main road, even during recent months when guys in high viz outfits driving tiny diggers would regularly park up around there and talk seriously about sewage pipes.  I suspect the more knowledgeable would call it an ecotone – an area where a number of different habitat types meet (… main road, suburban grass deserts, bush, privet rainforest, bike path…)

Equally interesting is what I don’t see in this little patch of scrub and noxious weeds.  I’ve spotted a wattlebird or two, but the mynahs and the currawongs seem to prefer the closely shaved lawns and unlovely topiary of adjacent suburbia only a few hundred yards away.

It’s lucky, probably, that the water dragons don’t share my landscaping snobbery.  They seem equally happy basking on the buffalo grass by the kerb, nestling under the hateful row of aloe plants, or zipping into the hinterland of privet, ehrharta and abandoned tyres.  I guess a suburban lizard’s gotta do what a suburban lizard’s gotta do.
