Over the past week, hundreds of lorikeets have fallen from the sky, paralyzed by a disease that researchers are struggling to understand.
More than 200 birds paralyzed by a little-known disease called parakeet paralysis syndrome (LPS) were rescued in the area around Grafton in northern New South Wales in the week leading up to Thursday.
Approximately 40 percent of these beautifully colored birds will not survive if they contract an unusual disease, but the cause remains unknown.
Birds that can’t blink, can’t eat, can’t fly
Since LPS was identified in 2010, thousands of lorikeets have been killed by LPS, mainly in southern Queensland and northern New South Wales, Australia.
Birds appear unsteady as they hop around on the ground, and their legs and wings are paralyzed to varying degrees.
In the most severe cases, the paralysis may affect the entire body and the parakeet may be unable to blink or swallow.
David Farren, a professor of wildlife health and conservation who specializes in LPS, called this a “major animal welfare crisis.”
“These animals suffer tremendously before they die, before they are killed by cats or found by possums,” he says.

“They are amazing birds,” Professor Farren added. scientific american last year.
“They’re smart. They’re fun to watch. They’re beautiful. It’s hard to see them this sick. But at the same time, they’re fighters.”
WIRES Clarence Valley Bird Coordinator Robin Gray said she had cared for more than 80 birds this week, but “many of them never make it.”
“When they arrive, they are underweight, malnourished and very sick birds,” she said. ABC.
“Professors from the University of Sydney in Currumbin and Australia Zoo in Sydney are carrying out experiments, but no one can give us a definitive answer.”
Despite the bleak outlook, veterinarians and volunteers are working tirelessly to rehabilitate sick birds.
In November, RSPCA Queensland adopted four paralyzed parakeets and named them Mash, Chippy, Tater and Spud.
The birds were treated with fluids and nutritional therapy, painkillers and eye drops to prevent their inability to blink.
“Unfortunately, Spud has lost the battle against LPS,” the charity said in an update.
“But Mush, Chippy and Tater continue to go from strength to strength. All three have shown amazing improvement. They are now able to get on perches and are feeding on their own. Ta.”
The mysterious cause behind a nasty disease
Although researchers have struggled to pinpoint the factors behind LPS, a leading theory is that it is caused by pathogens that parakeets ingest when eating certain fruits and flowers.
The disease is seasonal, occurring from October to June each year, with the highest number of cases occurring from December to February, which could be explained if it is associated with summer plants. yeah.
“Not all the fruit they’re eating is necessarily poisonous, so perhaps the toxin is forming within the fruit. [fruit is] It disappears,” Professor Farren explained.
“Or maybe it is. [the fruit is] When pesticides or fungicides are applied inadvertently or intentionally. ”
However, all known insecticides and fungicides are excluded, as is the presence of infectious diseases.
“We believe there may be toxins out there that we haven’t tested for yet, and that will be the focus of this year’s research,” Professor Farren said.
appeal to the public for cooperation
With so much uncertainty, scientists are asking the public for help.
researchers Parakeet Paralysis Syndrome Project Birdwatchers between Bundaberg and Grafton have been asked to report what lorikeets are eating.
The information you provide will help narrow down the list of potential causes of LPS.
“We approach this problem like veterinarians investigating patients,” Dr. Farren said.
“But it’s not just one patient. It’s a whole herd.”
