Mysterious Paralysis Syndrome Raises Alarm for Rainbow Lorikeets and Flying Foxes in Australia

A troubling surge in a mysterious paralysis syndrome affecting rainbow lorikeets and flying foxes has emerged in Queensland and New South Wales, leading to thousands of hospitalizations in the past year. The condition hampers the animals' ability to fly, swallow, and even breathe, prompting concern from wildlife experts.

Known as lorikeet paralysis syndrome, the condition has been noted in lorikeets since at least 2012, while a similar syndrome was identified in flying foxes five years ago. In 2024, the RSPCA admitted a staggering 1,079 flying foxes and nearly 8,000 lorikeets to its wildlife hospital in Brisbane, significantly up from historical averages of 2,600 lorikeets and 200 flying foxes annually.

Despite the uptick in cases, researchers have not determined whether the two syndromes share a common cause. Seasonal spikes typically occur each December and January, with wildlife experts noting a potential further increase in affected animals in the coming weeks as warmer months approach.

Dr. Tim Portas, a wildlife veterinary director, emphasizes the severity of the situation, stating that the most common reason for lorikeet admissions has been paralysis syndrome. Severe cases lead to loss of critical functions, resulting in dehydration or suffocation. Experts urge the public to report sightings of unwell animals to local wildlife rehabilitation groups for appropriate care, rather than attempting to intervene directly.

The investigation into the condition continues as scientists explore possible environmental factors or toxins contributing to the syndrome.
