Imagine a bird so striking it could captivate any nature lover with its bold black mohawk and vibrant red cheeks. But this isn’t a bird-watcher’s dream—it’s South Australia’s latest nightmare. The red-whiskered bulbul, a seemingly innocent yet highly invasive species, has escaped captivity and is now on the run, sparking fears for the state’s $2 billion horticulture industry. And this is the part most people miss: its presence highlights a potentially gaping hole in Australia’s biosecurity system. But here’s where it gets controversial: could this be just the tip of the iceberg, with more invasive species slipping through the cracks? Let’s dive in.
This lone fugitive bird was first spotted in northern Adelaide several weeks ago, likely having escaped illegal captivity. While it might seem like a minor incident, the stakes are sky-high. The red-whiskered bulbul has already established itself in parts of New South Wales and Queensland, where it wreaks havoc by damaging crops, spreading invasive weeds, and outcompeting native bird species. James Johnson, a senior advocate at the Invasive Species Council, warns, ‘This could be the start of a new invasion if we don’t act quickly.’ The bird is banned in South Australia, yet someone illegally brought it in, likely as a pet. ‘We haven’t found it yet,’ Johnson adds, ‘so we’re urging the public to keep an eye out and report any sightings.’
What makes this bird so dangerous? For starters, it’s been linked to the spread of invasive species like feral olive trees in Western Sydney, posing a significant threat to both the environment and agriculture. Johnson points out, ‘It’s been spotted in Salisbury, which is alarmingly close to our northern agricultural areas. If it reaches fruit-picking regions, the damage could be catastrophic.’
South Australia’s Department of Primary Industries (PIRSA) has been on high alert since the bird was first reported in late November. A spokesperson explains, ‘This is no ordinary pest. It can decimate vineyards and orchards by feasting on soft fruits, flower buds, and insects, potentially slashing yields or even causing crop failure. With the state’s $1.8 billion wine and $2.08 billion horticulture industries at risk, we’re pulling out all the stops to eliminate this threat.’
But the red-whiskered bulbul isn’t the only bird causing trouble. Last summer, orchards around Adelaide faced massive losses as flocks of lorikeets stripped trees bare in minutes. Mark Filsell, an apple and cherry grower in Forest Range, knows the struggle all too well. ‘It’s a huge expense to net an entire orchard,’ he says, ‘especially when you’re dealing with lorikeets during the day and bats at night.’ Thankfully, lorikeet numbers were low this year, but Filsell is wary of adding the bulbul to the mix. ‘We’ve seen what happens in places like Victoria when orchards aren’t protected—you end up with nothing.’
This incident has also reignited debates about Australia’s biosecurity measures. Johnson argues, ‘The government needs to rigorously protect our borders, but we also need to address the movement of invasive species across state lines. Biosecurity is every Australian’s responsibility.’ South Australia has already faced two small incursions of red-whiskered bulbuls in recent years—10 wild birds in the Adelaide Hills in 2017 and eight illegally kept birds in West Croydon in 2018. PIRSA confirms all were captured or removed, but the question remains: how many more are out there?
Keeping a red-whiskered bulbul is illegal and can result in hefty fines. If you have any information about sightings or breeding, contact PIRSA Biosecurity or call the Pest Alert Hotline at 1800 084 881. But here’s the bigger question: Are our biosecurity measures strong enough to prevent the next invasion? Let us know your thoughts in the comments—this is a conversation we can’t afford to ignore.
