Something alarming is happening to magpies in Western Australia, and scientists are racing to uncover the truth. A mysterious neurological condition is affecting these iconic birds, leaving researchers puzzled and the public concerned. But here's where it gets even more intriguing: despite months of intensive investigation, the exact cause remains elusive. Could it be a hidden pathogen, environmental toxins, or something entirely unexpected? Let’s dive into the latest updates from Murdoch University’s groundbreaking research and explore what’s at stake.
In April 2025, Murdoch University joined forces with WA Wildlife to tackle this enigma head-on. Their mission? To unravel the secrets behind the neurological syndrome plaguing magpies across the region. Armed with data from recent cases, the team launched a comprehensive study, examining everything from molecular pathogens to environmental contaminants. While they haven’t yet identified the culprit, their findings so far are both fascinating and frustratingly complex.
Dr. Flaminia Coiacetto, a Senior Lecturer at Murdoch University’s School of Veterinary Medicine, emphasizes the progress made. “We’ve ruled out several potential causes, which is a significant step forward,” she explains. “Though we don’t have all the answers yet, each piece of information brings us closer to understanding this puzzle. This work is intricate, but it’s crucial for protecting these birds and our ecosystem.”
What Did the Research Entail?
The investigation unfolded in three critical phases:
1. Molecular Testing: Researchers screened for known and unknown pathogens, including viruses, bacteria, and parasites, while also checking for notifiable diseases like bird flu and Newcastle disease.
2. Environmental Contaminant Screening: Liver samples were tested for over 250 substances, ranging from heavy metals to pesticides, herbicides, and rodenticides.
3. Post-Mortem and Pathology: Organs and tissues were examined under microscopes to detect signs of disease or infectious agents.
Key Findings So Far
Dr. Bethany Jackson, from Murdoch University’s Centre for Biosecurity and One Health, sheds light on the results. Notifiable diseases like bird flu and Newcastle disease have been ruled out, and botulism, though not entirely excluded, hasn’t been detected. Interestingly, glyphosate was absent from all samples, but low levels of legacy pesticides, rodenticides, and heavy metals were found. However, these were present in both affected and unaffected birds, complicating the picture.
And this is the part most people miss: the presence of second-generation rodenticides in the samples. “These contaminants persist in the environment,” Dr. Jackson notes. “It’s a stark reminder of the need to use pesticides, herbicides, and rodenticides responsibly, considering their long-term impacts on wildlife.”
What’s Next?
The team isn’t giving up. They’re now focusing on potential infectious agents, such as blood parasites and insect-borne viruses, and comparing ‘normal’ cases to those showing neurological symptoms. Further testing and treatment trials are planned for the upcoming season.
Here’s where it gets controversial: Dr. Coiacetto admits that complex wildlife diseases like this often take multiple seasons to investigate, and sometimes no definitive cause is ever found. “We’re committed to continuing this work,” she says. “But we need the public’s support and patience as we navigate this challenging journey.”
Public Guidance
If you spot a live bird showing signs of paralysis, contact the Wildcare Helpline at (08) 9474 9055 or take it to a wildlife carer. For five or more sick or dead birds in one area, report it to the Emergency Animal Disease Hotline at 1800 675 888. But don’t collect deceased birds for research—the team requires specific, time-sensitive samples.
This project wouldn’t be possible without the support of NMI laboratories, DPIRD, wildlife centers like Darling Range Wildlife Shelter and Perth Wildlife Hospital, volunteers, private donors, and Murdoch University’s dedicated staff. Their collective efforts are vital in addressing this unusual condition.
