A day out at the pool with the kids

During most of spring we woke up every morning to the sound of sparrowhawks shagging.  But for the last couple of months the alarm clock has been the crack of a whip.

An eastern whipbird pair have been whiling away time in our garden, offering their distinctive antiphonal duet – the male first with his whipcrack, followed up by his mate with a “chu chu”.  But they’ve had an extra with them this year – a youngster, with a kind of squelchy call that reminds me a bit of the red-crowned toadlets that I’ve been hearing on the fire trails throughout this soggy soggy summer.

The whipbirds have some interesting child-rearing habits, according to researchers Amy Rogers and Raoul Mulder.  They usually lay a couple of eggs.  Once the chicks fledge, the parents divide the task of looking after the kids quite formally between them.  Each parent looks after one of the fledglings exclusively.  You can imagine the therapy bills .  There’s an exception – if only one chick survives, then it’s mum who’s in charge.  So I guess it’s maternal care we’ve seen as we’ve watched the adult and juvenile slipping in and out of sight around the garden.  There’s definitely a whip-cracking male around, but all thee have only been spotted together in the garden once – and I wasn’t there with my camera to catch it, so I question if it ever really happened.

Whipbird chicks spend about six weeks with their parents after fledging, sometimes even hanging around until the next season, and it’s been interesting watching the adult and its offspring interacting, as the young one slowly morphs from its slighty fluffy, brown “I just came out of the nest” look to something more like an adult appearance.

I think one reason the whipbirds make such regular appearances in our yard is the frightful mess it’s in.  We’re not path sweepers or lawn groomers.  More stick-pilers, fungus-harbourers and ignorers-of-organic-detritus.  My efforts to promote biodiversity are not solely confined to a failure to rake, however.  I’ve sunk the value of at least one of the kids’ kidneys into shrubs, vines and groundcovers, some of which have survived.  While I have regularly seen the whipbirds in our kiwifruit arbor and the youngster has been spotted leaping about in a demented way amongst the ferns and vines outside our kitchen window, the native violets, which are threatening to overrun the house during this wettest summer in 30 years, seem to be a favoured spot.

Here we see chick watching mum head down bum up in the viola hederacea (you can just see the tail in the lower half of the first picture).  Next it’s little one that has its butt in the air, retrieving something invisible but presumably tasty.

Despite their furtive habits and preference for the undergrowth, it turns out whipbirds can be pretty assertive under the right circumstances.  I was impressed by the use of eye contact in a  show-down with one of our many resident brush turkeys over a bird bath.

The best time to spot two generations of whipbirds is around lunchtime, at the birdbath.  Mum arrives first, has a wash and then a bit of a groom, perched above on some wonga wonga vines.

Having watched this scene of filial affection unfolding around the birdbath at home, I was quite delighted to catch what I thought were some similarly touching moments at a pool in a more natural setting.

As a devoted parent, I’m always happy to drive my kids to music lessons… especially if the music teacher’s home happens to be right next to a national park.  On a sunny late afternoon during one of these high-speed twitching sessions, I spotted some action high up in a Sydney red gum.

A hollow on top of a horizonal branch seemed to have formed a natural pool which was evidently a magnet for the local birdlife.

I could see that there were some juvenile spinebills about, and some adults too.  Squinting through my lens I wasn’t quite sure what kind of pool side action was going on up there in the canopy.  Perhaps adults giving a tour to youngsters of all the best places to drink and bathe in their forest home? Showing them the ropes in this lofty aquatic environment – explaining the avian equivalent to those “no petting” “no bombing” rules perhaps?

When I got home and had a good look at the photos I found out otherwise.

These poolside antics give “competitive dad” a whole new meaning.

Apparently, spinebills can have up to 5 clutches of eggs each year – almost as soon as one clutch are fledged, the parents start making a new nest ready, driving the older juveniles away.  And no free pass for the pool it seems!

Much as I love the gorgeous spinebills, for human Sydneysiders with our eyewatering real estate market and clutches of offspring near at hand, somehow the parenting style of the whipbirds feels closer to home.

Cracking the whip in a messy garden

Typical whipbird picture crop tighter

This is a fairly typical photo of an eastern whipbird.  Thanks to its cracking call, you know with absolute certainty that the bugger’s there somewhere, darting from bug to evasive bug.  But up until recently all of my pics of them were abstract impressionist in style – an suspicion of a smear in the undergrowth.

Which is a pity, because even aside from their excellent call, these are fine looking birds.  I am a fool for anything with a crest, no matter how run of the mill.

But my days of cursing invisible whipbirds are officially over.  Because we now have a  resident pair in our the garden.

My efforts at growing food in surburbia, or at least food for human consumption, have been largely in vain.  Every now and then we get a few bananas or kiwifruit, tamarillos or jerusalem artichokes before the local possums, bowerbirds, cockies, bats and rats figure out they make good eating.

If I have singularly failed to feed us, I have been fairly successful in turning the garden into a tangled mess riddled with trip hazards.  In other words, top drawer whipbird habitat.

And now they’re here, there’s a decent chance they’ll stay.  Whipbird pairs are territorial, usually nesting each year within a few metres of last year’s spot.  And it seems after their chicks are raised, they stick around.

I’ve certainly seen our pair doing their best to defend their territory by seeing off the impudent rivals they spotted in the mirror in the bottom of the garden. Judging from the time they spend singing into it, that mirror has had far more impact on the whipbirds than the horde of male brush turkeys it was intended to discombobulate.

Something I didn’t realise until recently is that the distinctive call of the whipbird is an “antiphonal duet”, just like the call of the koels (or “those bloody koels!” as they are known locally).  The male of the pair produces the whipcrack, followed seamlessly by a “chew chew!” from its female partner.  This kind of singing is usually done by established pairs.

Tactful ornithologists describe whipbirds as “socially monogamous” (a bit like National Party MPs?).  Whipbird researcher Amy Rogers comments that, in general, duetting birds like these have “very low divorce rates” compared to non-duetting birds (Rogers 2004 433).

Having spent years crouched in the undergrowth surreptitiously observing the sex lives of South Australian whipbirds, Rogers has has concluded that duetting is “acoustic mate guarding” – a way for females to keep close tabs on their other half. In the nests she tracked, twice as many female birds were born as males.  Consequently spots with attractively tangled undergrowth were awash with unattached lady whipbirds seeking a mate and territory.

Whipbirds blokes seem to be a good catch, fetching plenty of food for nestlings, even if they don’t help incubate eggs.  After the youngsters leave the nest, each parent exclusively feeds just one of the fledglings. You can only imagine young whipbirds end up spending a fortune in therapy.

So once a female has hooked up with a male and they’ve nabbed some decent territory, she keep tabs on him by finishing his sentences, as it were.

I reckon our place, with its undisciplined shrubbery, snake-friendly piles of sticks and vines that loop their way through the trees at perfect garotting height would be damn desirable breeding grounds. I’ve certainly seen the whipbirds gleefully leaping around our carport picking off the window spiders (3/5 for toxicity in the “deadly critters of Australia” book I gave my Scottish spouse to help him settle in when he first arrived).

It may be cockroach infested deathtrap but the whipbirds and the lizards seem to like it here.  I’m not complaining either.

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:

Cornish witches' vehicle small crop.jpg

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.

Danger! High voltage!

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.

Firetails flying off horizontal crop

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!

Firetails alert plus wren crop closer

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.
