Key Takeaways
- The red-whiskered bulbul, a bird native to southern Asia, has been spotted in Adelaide, South Australia, prompting concerns for the state’s $2 billion horticulture sector.
- The bird is considered a high-risk pest that can damage vineyards and orchards by eating soft fruit, flower buds, and insects, potentially reducing yields or causing crop failure.
- Authorities are searching for the single bird, which is believed to have escaped captivity, and are urging the public to report any sightings.
- The Invasive Species Council is calling for increased biosecurity measures to prevent the spread of invasive species like the red-whiskered bulbul.
- The bird’s appearance in Adelaide has highlighted a gap in the nation’s biosecurity and the need for rigorous protection of the environment and agricultural industries.
Introduction to the Red-Whiskered Bulbul
The red-whiskered bulbul, with its distinctive black mohawk and red cheeks, may seem like a bird-watcher’s delight, but it has become a major concern for authorities in South Australia. The bird, which is native to southern Asia, has been spotted in Adelaide’s north, prompting fears that it could establish a population and wreak havoc on the state’s horticulture sector. The red-whiskered bulbul is considered a high-risk pest that can damage vineyards and orchards by eating soft fruit, flower buds, and insects, potentially reducing yields or causing crop failure.
The Risks Posed by the Red-Whiskered Bulbul
The red-whiskered bulbul has already established populations in parts of New South Wales and Queensland, where it is damaging crops, spreading weeds, and competing with native birds. Invasive Species Council senior advocate James Johnson is concerned that the bird’s appearance in Adelaide could be the start of a new invasion if it is not caught and removed quickly. The bulbul is implicated in the spread of weeds like feral olive trees in Western Sydney and poses a major risk to the environment and agricultural areas. Mr. Johnson is urging the public to keep an eye out and report any sightings of the bird, which is believed to have escaped captivity.
The Search for the Red-Whiskered Bulbul
Authorities are actively searching for the single red-whiskered bulbul, which was first spotted in late November. The South Australian Department of Primary Industries (PIRSA) has distributed information in the area to try and track the bird down and eliminate the potential threat. PIRSA is warning that established populations of the bird have caused significant problems for soft-fruit and citrus growers interstate and overseas, highlighting the risk and cost if they become established in South Australia. The department is urging anyone with information about breeding or sightings to contact PIRSA Biosecurity or report it to the Pest Alert Hotline.
The Impact on Horticulture
The red-whiskered bulbul’s appearance in Adelaide has highlighted the significant risks posed by invasive species to the state’s horticulture sector. Last summer, birds caused huge losses to orchards around Adelaide, reportedly stripping entire trees of their fruit in just minutes. Forest Range apple and cherry grower Mark Filsell says that birds can quickly decimate unprotected orchards, and the cost of covering entire orchards to protect them from bird and bat damage can be massive. Mr. Filsell is concerned that the red-whiskered bulbul could add to the problem of pest birds in the region, which already includes lorikeets and bats.
Biosecurity Concerns
The red-whiskered bulbul’s appearance in Adelaide has also raised concerns about potential gaps in the nation’s biosecurity. Mr. Johnson is calling for the Australian government to rigorously protect the environment and agricultural industries at the border, as well as to invest in tackling invasive species when they are detected. Biosecurity, he says, is every Australian’s responsibility, and it requires a concerted effort to prevent the spread of invasive species like the red-whiskered bulbul. The incidence of the bulbul in Adelaide is not an isolated one, with South Australia having recorded two small incursions of the bird in recent years. However, all of these birds were either captured or removed, and authorities are hoping to prevent the establishment of a population in the state.
