Lorikeet Paralysis Syndrome (LPS) is a seasonal disease that occurs every year between October and June, causing lorikeets to drop out of the sky and become unable to move.
Ornithologists and veterinarians have known about Lorikeet Paralysis Syndrome for many years now, but despite their best efforts, the cause of the disease has remained a mystery. That is particularly alarming because the disease affects thousands of birds every year, and proves fatal to many of them, rendering them unable to feed or escape predators. Cases of LPS have been reported in Australia since 1970, and although scientists have been able to eliminate some probable causes, they still don’t know what causes it.
