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.

Recently fledged juvenile whipbird

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.

Showdown at the 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.

Murder, imprisonment and native grasses

This blog starts and ends calmly and peaceful as we consider lush grass growing.  In the middle there’s some horrifying interspecies violence – I’ll tell you before it happens so you can look away if you need to.

When we first into our place nearly a decade ago, there was plenty of grass in the backyard.  Note, I don’t say lawn.  Which is fine by me, since an array of weeds offer much better nutritional resources for chickens than a monocultural sward.

So a sequence of domestic fowl have enjoyed the delicious mix of trad, ehrharta, buffalo grass, couch, and a plethora of other greens as a supplement to their laying mash and scratch mix.   The trad went first.  Chickens absolutely love this horrid weed and have scratched out every shred, producing the fabulously golden yolk that are a definitive feature of your happy free-range egg. For a while the other grasses held on, but, over a few dry winters, as our flock grew to six chooks and an apparently infinite number of semi-resident brush turkeys, the greenery eventually lost the fight.

Perhaps not surprisingly, I don’t have a lot of pictures of the muddy home farm during this “trench warfare” period.  And I have absolutely no pictures of the traumatic events that followed.  It’s taken me nearly a year to get up the gumption to write about it.

Baby brush turkey astonished

Very cute baby brush turkey hanging out with our chicks a couple of years back

Until November last year, the many brush turkeys hanging around the backyard were an annoyance but nothing more: scratching up seedlings, stealing eggs and making free with the chickens’ dinner.  The baby brush turkeys liked to huddle up to our newly hatched little chicks.  The older turkeys also seemed to like hanging out with the flock but were easily spooked by them.  It only took boss chook Treasure giving a funny look to have the brush turkeys scatter or even flap away. But that all changed last spring.

A large male brush turkey started hanging around, pursuing and doing his best to mount the chickens.  One day we noticed that several of the girls’ combs were bloodied, and concluded it was the work of this nasty animal. The neighbours had spotted the sex predator too. There were rumours of pet birds being attacked all up and down the street.

Concerned, we decided to keep the girls in Colditz, the steel-framed predator-proof cage for a day or two, rather than letting them roam the yard as usual.  The next day I was working from home, and by the afternoon, seeing no signs of the turkey and feeling sorry for the poor chooks pacing up and down in their constrained night quarters, like Steve McQueen in the Great Escape, I decided to let them out for a few hours.  I went back to my computer.

If you are easily upset, now is the time to look away.

Late that afternoon I heard a pitiful squawking and rushing down to the yard.  All of the chooks were bleeding copiously from their scalps and two of our poor girls were mortally wounded, with huge slashes through their backs and terrible gouges to their heads.  Then we heard pitiful sounds from the last of our neighbour’s free-range chooks.  We jumped across the fence to rescue it, but too late – its eye had been pecked out. All three birds died soon after.

Needless to say I was inconsolable.

The only way I could atone my guilt was to make the surviving chickens a safe place to stay.  So that Saturday, in a frenzy, I pulled together an implausible collection of wire, wood from futon bases, half an aviary, parts of a picket fence, innumerable pieces of bamboo and that old standby, trampoline netting, to make a 8 square metre covered run adjacent to Colditz. The run featured Palm Beach as an elevated hangout zone and egg laying area, perches at a range of heights and diameters and its own personal orange tree.

The chooks were safe, and over the next few weeks slowly recovered from their head wounds.  But they weren’t happy.

So over the festive season, I had another crack, making an extension the same size again, which admittedly did involved purchasing a couple of steel droppers and a box of screws.  Otherwise, I was extraordinarily pleased I was able to make the “outdoor room” entirely from rubbish I scrounged from the side of the road.

Now the chooks were secure in their generous run, an unworthy thought came to me.  The scorched earth of the backyard, without a single blade of grass and denuded of  every remaining seed, was now perfectly prepared for something I’d long aspired to have – a backyard full of native grass. The kids had started expressing a longing for a little bit of soft lawn to walk on, and I was keen to take on the challenge.  Buffalo, kikuyu and ehrharta outcompete native grasses, but thanks to the chooks, I doubted there was a single weed seed left on the premises.

It was time.

I decided to mostly use microlaena stipoides, weeping grass, a fine bladed grass that tolerates shade and enriched soils and, once established, copes with minimal watering.  I ordered a couple of hundred grams of a hybrid microlaena called Griffin weeping grass, a low growing variety bred by the Department of Botany at the University of New England.

My first sowing was in early summer – the best time for this variety – warm enough for a speedy germination and not so hot it’s impossible to keep the seed bed moist.  I raked in the seeds – they shouldn’t be buried more than 1 and a half centimetres deep – and covered them with the veggie nets that I usually use to protect seedlings from bowerbirds, chickens and possums that aren’t trying too hard.

The Great Berowra Storm of Christmas 2018 treated us relatively kindly ( two broken skylights is a pretty good outcome from golf ball sized hail) but did significantly undermine my efforts to even distribute those rather expensive grass  seeds.  But I guess the torrent saved me watering for a few days, as well as reminding me why we needed grasses and their root systems to stop our topsoil flowing away on those occasions when our yard becomes a tributary to Berowra Creek.  On hot days when we didn’t experience a climatic apocalypse, I did get out the hose for the first month or two – microlaena needs to be kept moist until its root system is sorted.

In the light of its inpropitious beginnings, the microlaena has done pretty well, coping with the chooks snacking on it a couple of days a week.  That brutish brush turkey has never returned (I suspect foul play given his cruel behaviour to most of the hens in the street) but we like to let them roam when we can keep an eye on them.  And the native grass has remained beautifully green through yet another very dry winter.  In the picture above, alongside the weeping grass, you can see my low-skill terracing with fallen wood and another native grass, poa labillardiere. The aim is to redirect any storm water into our new pond (more on that another day)

So after two days of drenching rain,  I decided this afternoon to sow another packet of griffin weeping grass, filling the gaps scoured by last December’s floods.  Yet more trampoline netting has been hauled out of the shed to protect the newly spread seed from the chooks on their weekend perambulations.

Even if I’m slightly nervous of what they might do to my baby grasses, I’m grateful to our girls.  Without their commitment to scratching and salad, we would never have got this far, and certainly not without reaching for roundup or something equally scary.   I hope I can return the favour by keeping them safe (if not always happy) and feeding them plenty of greens.

What’s inside the bird cage?

Not artichokes.

I spent all of last autumn dreaming of artichokes.

In the three years since my last bumper crop, which grew splendidly with no attention at all while we were half a world away, I have tried and failed to get more magnificent edible thistles towering over my veggie patch.

Our garden is a challenging environment for any seedling.  I suspect the sad fate of the last two generations of artichokes can be attributed to the deep gloom that descends on the yard around the time of the autumn equinox.  But there are other possible suspects in the frame…

Yes, rabbits.  My transition to the Mr McGregor, the homicidal carrot fancier in Peter Rabbit is now complete.  But so far I’ve avoided GBH with a shovel.  Instead I got me a fine flock of bird cages.

A budgie lover in Berowra must have had a mass break-out just before the last heavy rubbish day and I was the lucky beneficiary.

But my visions of bounty weren’t to be.  I’m not sure if some small but dextrous herbivore lifted up the tiny food hatch and sneaked in for a unappetising meal of baby thistles or if the artichokes lost the will to live in dank captivity.  On the upside, budgie cages are evidently great at keeping rabbits off your rocket.

Not strawberries

So, there are no artichokes in my bird cages.  And so far, there’s no strawberries either.

My other score from the last council cleanup was a load of aviary wire and some nice hardwood architraves.  A few bucks on hinges and I was able to put into place the final stage of my termite-assisted plan to reduce my erstwhile (and totally pointless) garden path into rotten timber. My aim: to grow strawberries under the flight path of the gate-that-used-to-be-a-bed.  Or more precisely, to grow strawberries for human rather than chicken consumption.

I was pretty happy the outcome of my chookhouse-tolerances joints, held together with an assortment of mixed screws from the jar at the back of the cupboard.

Thus far the chooks haven’t managed to break in but the strawberries seem somewhat oppressed by their location.  Every day is a bad hair day.  I’m hoping they’ll be ugly but productive but the signs don’t look good so far.

On the bright side, lazily throwing scratch mix over the gate has produce a little protected patch of green in the razed earth of the chook yard.  I’m not sure the strawberries enjoy the competition from wheatgrass, but the hens have a hippie feast every time I do the weeding.

Fewer chickens than there oughta be.

Sadly, on one bleak and rain drenched evening in the middle of winter, most of our hens weren’t in the birdcage either.  Only Cyan, bottom of the pecking order thanks to her gammy eye, and Treasure, broody as usual, were in Colditz, the predator proof cage, when a hungry fox came to visit.

Only one of the chooks that had been perched in the favoured roost, the potted fig tree, survived, a fairly run-of-the-mill Barnevelder whose name we could never quite remember.  After the slaughter, we renamed her Xena as a mark of her prowess in battle.  Bold and beautiful Cleo, curmudgeonly Snowball, at least 8 years old, feisty Morgan, shy but reliable Abby and inexpertly named Tigress all disappeared or were found in bits in the yard the next morning by the shellshocked RB.    Given the sad end of Shyla under similar circumstances at the same season the year before, you can only conclude we are poor chicken keepers and, frankly, very slow learners.

So now, come rain or shine, you’ll find our remaining hens locked up every night.  At the moment, it’s a lonely night for Xena, locked up in Palm Beach.  Her mum, Treasure, laid low by has some mysterious ailment, has been in the intensive care ward in the laundry, while one-reviled Cyan has now attained the pre-eminent position of queen of Colditz, adoptive mother to three new day-old chicks.

Fortunately, Xena can always rely on her playdates.  Just like next doors’ kids, the neighbours’ hens nip through gap in the fence and hang around outside waiting for our girls to be let out for the day.  They share a feed and if we’re lucky lay an egg or two on our side of the “magic portal” (to clarify: we get eggs from the chooks but sadly not the kids).

Three cheers for the return of stay-at-home scrumping!  Low-level food thievery without even leaving your own backyard.

And no baby brushturkeys

Until they’re 12 weeks old, the chicks are confined to Colditz along with their adoptive mum, in case they get eaten by a kookaburra or pecked to death by one of their loving aunties.  None of them are taking imprisonment well.

Smuggling the chicks (sexed and vaccinated and genetically disparate) under relentlessly broody Cyan at the crack of dawn was a doddle. Especially compared the sleepless night I spent as a ignorant featherless human trying to keep the wee things safe and warm in a cardboard box under a desk lamp without setting the house on fire.

chicks-in-sunlight-eye-open-crop

They were happy at first.  But these days, the chicks and their mum spend most of their time pacing the length of the cage, apparently hoping to find a hidden exit.  Their only distraction is the thrill of scratching through the bug, straw and leaf litter mixture left in the potato patch after this year’s laughably miniscule harvest of spuds.

They’re particularly plaintive when they have visitors.

I’m not sure if all that frantic peeping is concern that one of their number has apparently gone astray from the flock, or jealousy that the baby brush turkey is free to roam the yard at will.

The little brush turkey spends a surprising amount of time close by, staring intently into the cage.  Perhaps there’s something more to it than the chick crumble dropping through the wire floor.  One night, tiptoeing down to shut in Xena for the night, I saw him roosting there, right on top of the cage.  Strange behaviour from a chick that never meets its siblings or its mother, let alone snuggling together with them at night.

Bandicoot in the Sacred Garden

Is it just me, or does this sound like the title of an atrocious 1970s Australian erotic film? Admittedly I’ve never heard a bloke describe their wedding tackle as any kind of marsupial.  Is this a failure of the national imagination? Possibly.

Anyway, the “sacred garden” is not as lewd as it sounds – it’s the name our eight year old has given the veggie patch that shelters beneath the frame of our ancient trampoline.

I’m not quite sure why she views it as a holy site.  It could be the shape.  In the organic gardening world, it seems, circles, mandalas and spirals have some mystical life-giving power that doesn’t flow through your old fashioned rectangular plot.   I’m skeptical, but at this stage in our death-match with the brush turkeys I’ll take any advantage I can get.  From chook dome to remodelled tramp to recycled children’s bicycle wheels, there are no corners here.

And the Mandala of Aviary Wire does seem to have worked its magic on my brassicas, despite extreme flimsiness.  Having been abandoned by the side of the road after a rich and full life getting between bouncing children and broken ankles, the trampoline net is more a spiritual than a physical barrier to aerial raiders, held in place by optimism and zip ties.  But to date, my newly planted garlic – positioned, of course, in a protective ring around the broccoli – has remained in the ground and my crop of red mustard and baby bok choi, while small, is perfectly formed.

It’s not looking so good on the broad bean front, despite a lavender and rose geranium mulch that makes the chook dome smell like a seniors’ underpants’ drawer.  I’d like to think a benevolent long-nosed bandicoot is squeezing in under the wire to snaffle the curl grubs amongst the asparagus crowns.  But I suspect that in reality I’m hosting rodents with keen insights into the politics of eco-nationalism.  “When you go in and take the beans, Rupert, make sure you leave a cone-shaped hole.  That way the marsupial-loving hippie will never dare leave rat poison out again.”  If only I owned an infra-red video camera with a motion sensor I might find out for sure – or at least collect some footage of hirsute visitors for that retro Ocker erotica.

 

Brush turkey mathematics

Four hens + eleven teenaged brush turkeys + several decoy eggs in the henhouse = one fresh chicken egg a day.  I can’t quite nut out this equation.  There are three intractable maths problems here.
.
One is agricultural-cum-mathematical.  Why are three of our pampered pets failing to lay eggs?
.
The second is at the point where philosophy meets mathematics, along the lines of “how many angels can dance on the head of pin”. Just exactly how many brush turkeys can occupy one suburban backyard?  And why are there so damn many of them?
.
And then there’s the ethological question.  Given the apparently infinite number of turkeys, and clear evidence that they are unrepentant egg eaters, why are we enjoying any omelettes at all?
.

What with the festival of poultry diseases we have been hosting lately, it’s not a big surprise that only sprightly Shyla continues to lay a regular egg.  She’s an Australorp, a new fangled breed, presumably with disease resistance as one of her mod cons, while, say, Treasure with her tedious moulting and brooding, is a Light Sussex, a breed that’s been around since Roman times.  I reckon that kind of pedigree is going to her a proclivity to old fashioned things, like the distinctly medieval-sounding fowl pox.

Being Top Chook doesn’t hurt Shyla’s capacity to pump out eggs. She makes sure she gets the best snacks by belting up to the garden gate as soon as she hears me coming and bounding in the air to grab scraps before I get a chance to dish them out.

But I’m not sure the other girls are getting quite enough to eat.

Now, I’m not saying that they’re wimps.  Even ancient, diminutive Snowball the silky bantam will frighten off nosy megapodes that try to butt in while she’s in the middle of breakfast.  But the trouble is, the chooks never sit down for a three course meal.  They’re snackers.  A few minutes of frenzied eating, and they wander off to nibble grass, have a dust bath, or in Shyla’s case, follow me around hoping I have better treats – say, limp grapes or weevil ridden grain.  If that’s not forthcoming she’ll taste-test the wet washing or have a red hot go at pecking my butt.

Shyla’s certainly not one to let starvation diminish her egg supply.  But by the time the other hens realise seconds wouldn’t go astray, it’s a teeny bit late.

No-one is 100% sure why there are so many damn brush turkeys in Brisbane and the northern suburbs of Sydney.  “I’m supposed to be the expert on brush turkeys and I still can’t explain why that’s going on,” commented Professor Darryl Jones of Griffith University, talking to the ABC.  He reckons numbers in Brisbane have increased by 700 percent in the last 20 years.

In the early 1990s, scientists thought moggies snacking on the unprotected chicks would put a stop to the urban invasion.  Nope.  The cluey babies will listen out for the alarm calls of just about any old bird, and as long as there’s enough cover they’ve got a chance.  Fox and dingo baiting mean grown-up life has been less brutish and short, and the water-wise mulching habits of modern gardeners have made mound building in suburbia extremely convenient.  The odd gormless adult bird might be taken by an ambitious powerful owl, willing to have a go at prey “at least 103%” of its own body weight, according to the remarkably precise estimates of scholarly birdwatchers.  But let’s face it, these owls are just not powerful enough in the brush turkey execution caper for my liking.

If anyone knows about megapodes it’s Dr Anne “Brushturkey robochickGöth, working down the road from here at Macquarie University. She’s explored every aspect of the weird story of how brush turkey babies, all on their own, dig their way out of their giant natal compost heaps – “the most nonavian life history you can get among creatures that are still feathered and lay hard-shelled eggs” – and then figure out without any parental guidance what they should eat and what will eat them, not to mention what the hell other brush turkeys look like without a glimpse of their parents or siblings.  Its no wonder they have a thing about mirrors.

Dr Göth’s erstwhile colleague up in Queensland, Prof. Jones, comments “fortuitously her arrival [in Sydney] coincided with a marked expansion of populations in the vicinity of the northern suburbs of the city” (2007, 3).  Mmmm.  Coincidence, eh, Dr Göth?  The gardeners and chicken keepers of the north shore are deeply, deeply suspicious.  Anyway, whether or not she has been deliberately breeding an evil army of brush turkeys in her secret underground lab, Dr Göth is on the money about the cause of the population explosion in my back garden – the ready supply of chook food.

So onto the final maths problem.  If there is an apparently infinite number of megapodes in our backyard, how come they haven’t spotted Shyla’s daily egg, sitting there, sometimes all day, next to its plastic companions?  Can’t brush turkeys count?

Rumour has it domestic chickens are a dab hand at maths.  Three day old chicks can figure out where to go left or right for a bigger pile of edible stuff even when items are added one by one, and each pile is hidden behind a screen.  This research by Rosa Rigosa from the University of Padua has been reported in the Telegraph under the headline “Chickens are cleverer than toddlers”.  But on my reading, 3 day old chicks should be put in charge of pairing our socks after washing, as they seem to a better grip on arithmatic and object permanence than the adults in our household do.

I have looked and failed to find for research on megapode counting skills. Dr Göth obviously hasn’t started work yet on this critical issue in animal cognition.  So I can’t tell if our continuing egg supply is a consequence of brush turkey innumeracy or if they are just lulling us into a false sense of security before brutally snatching away our remaining hope of home grown-protein. I guess we’ll have to see how this one plays out with our convenience sample in the back yard lab.

And if 1000 words on brush turkeys is barely enough for you, why not go read some more?
