Incident - Lorikeet paralysis syndrome NSW & Qld - ongoing

Lorikeet paralysis syndrome is a seasonal syndrome which has been occurring in eastern Australia for a number of years. In the summers of 2023-24 and 2019-20, there were particularly high numbers of cases in northern NSW and southern Qld.
The syndrome primarily affects rainbow lorikeets (Trichoglossus haematodus) but has also been reported in scaly-breasted lorikeets (T. chlorolepidotus). Affected birds are unable to fly, with varying degrees of paralysis of the hindlimbs. In more severe cases, the paralysis may affect the whole body and the bird may be unable to blink or swallow, and have a significant change to the voice. Less severely affected birds may recover with supportive treatment.
Wildlife disease experts have been investigating this syndrome and a wide range of tests have been done. The current investigation has found no evidence of an infectious disease as the cause of this syndrome. The possibility of an environmental or plant toxin is being investigated.
The University of Sydney requests citizen scientists within the designated study site to report observations on iNaturalist including the plant species/food sources rainbow lorikeets were observed feeding on. Find out more HERE.
