Brown falcon and willy wagtail © Mike Gillam

Like most of Centralia’s birds, willy wagtails call out their name in clearly recognisable Arrernte. Artityerrityerre, pronounced ahditcher-ditcher-da, certainly evokes the rapid fire call of the cheeky willy wagtail.
Artityerrityerre is considered by many Aboriginal people to be a messenger but also a gossip so you need to make sure they’re not around if you’re talking secret business.
The Arrernte bird poster by well known locals Veronica Dobson and MK Turner notes: “If you kill the willy wagtail it will bring on a very cold winter. It can make frost drop like steady rain all over everything and the wind blow; so don’t kill the Willy Wagtail.”
A law protecting Artityerrrityerre is easily enforceable because in truth the willy wagtail has charmed the hearts of humankind since the beginning of time.
Highly visible in the suburbs, the wagtail also enjoys success in arid environments where surface water is scarce and birds must rely on moisture contained in their insect food. During one very hot and dry summer I encountered such a scene – a solitary wagtail waiting patiently for the food to come to him.
Shaped by the elements, baked by summer sun and eroded from within by a heaving mass of maggots, the carcass formed a surreal landscape. Gaunt mountains rose from weathered cow hide stretched over bones and regions still bloated with gas hinted macabrely at pastures and rolling hills in desperate need of rain.
Two weeks earlier the dawdling and spotlight-dazzled heifer had been thrown high into the air by the truck’s bull bar, carried fifty metres and spun sideways onto the shoulder of the road. The short-horn’s death was immediate and the carcass was found just before sunrise by kites patrolling the highway looking for roadkill.
It took a vehicle winch to pull the beast away from the road in an effort to avoid further deaths. The crows and wedge-tailed eagles arrived soon after and their alternate feasting and skirmishing lasted a week.
Now a solitary willy wagtail was in charge, the eagles and crows long gone. This had nothing to do with the tiny bird’s fear of predatory malevolence. Quite the contrary, the oafish eagles and cumbersome crows were no match for Artityerrityerre.
Wagtails don’t eat carrion, however. The third wave of flies had begun to emerge a few hours earlier and the wagtail snapped them up with ease. Launching itself into the air, performing backflips and somersaults for the pleasure of the chase; always returning to its spot on the rib cage summit.
As his belly filled the tiny bird became more selective of his targets and less interested in taxing stunts. The fly pupae in reserve would keep the wagtails feasting for another week at least.
In the lower levels the coleopterans were rapidly multiplying and other desert denizens from centipedes to geckos were arriving nightly to claim the tunnels and caverns of this new insulated citadel.
At midday the wagtail’s wife arrived and the two of them accounted for a fly every thirty seconds for the next hour before deciding to take a rest. First a drink was needed en route to the shade; a salve to cleanse that tickling at the back of the throat caused by the passage of so many fly wings.
The waterhole was located two hundred metres from the wagtails nesting territory in a dense forest of red gums that had miraculously escaped recent destructive fires. Nesting was always coordinated with a pair of magpie larks, often in the same tree but the larks always chose to be much higher up.
The presence of the larks afforded additional protection to the wagtails and vice versa. For all woodland birds the watchfulness and penetrating danger call of the larks rteye-rteye is life saving despite the prevalence of false alarms.
At this moment they were waiting for the larks to begin building their mud nest before commencing with their own. Nevertheless, the wagtail couple, paired for life, were hardwired for protection duties, nest or no nest.
Some years earlier they had produced three clutches of eggs, building a new nest on the third occasion after a pygmy goanna ate all fledglings from the second brood. Despite their bravery and vigilance, the loss of an entire brood was not unusual. The wagtails’ ability to defend against avian predators was unrivalled but they had no answer for the thick skinned snakes and goannas, less easily deterred.
On this day the wagtails drank and splashed on the water’s edge without concern, chasing a dragonfly half heartedly before retiring to the shade of the forest. From here they could watch the waterhole for intruders. The fly soup settled but the restless wagtails would not.
They sang a duet, pranced and fluttered their wings. The male showed his companion how he could frown and expand his white eyebrows and she jumped away in alarm. They perched with shoulders touching, all the while watching a procession of bird visitors to their waterhole.
Somewhere a strident call rteye-rteye rteye-rteye was quickly endorsed by the higher pitched chittering of white plumed honey eaters tyetyapweretye. Both wagtails tensed. The brown falcon landed a short distance from the waterhole and sauntered to the shoreline, wading into the shallows and shaking the dust from its feathers in anticipation of a splash bath.
The falcon was a lizard specialist but its resemblance to the terrifying harrier was provocation enough for the wagtails. They allowed the raptor a brief drink and then they came fast and low, chattering with intensity and working as a well practiced team. The falcon danced from foot to foot, head spinning but always facing the wrong way and feeling the wagtails clip the back of its head.
Nearby the urgent voice of the magpie larks was repeated over and over alerting the guild of woodland birds to the falcon menace. With backup on the way the wagtails increased pressure on the falcon, even digging their claws into the unfortunate intruder’s scalp. It was too much for the falcon.
The victorious duo gave chase, striking the falcon with bouncing kicks to the back and soon a posse arrived led by the magpie larks and including a black faced cuckoo shrike, two white plumed honeyeaters and an indeterminate number of yellow throated miners. Even a curious crow joined in, flying alongside the wagtails and they seemed content with its presence, a case of the enemy of my enemy is my friend, for the moment at least.
