Justification of Red List category
This species has an extremely small wild population (<30 mature individuals) and is now known to breed at only one site, where it appears to have undergone an extremely rapid recent decline. Reasons for this recent decline are unclear, though the species has suffered from previous loss, fragmentation and degradation of winter habitat, and changes to fire regime in the breeding habitat. Likely causes of the recent decline are an outbreak of Psittacine Beak and Feather Disease in 2014 and the effects of a ten-year drought on productivity of saltmarsh plants in the winter habitat that reduced the breeding condition of females. It is also likely that the lack of habitat burns in the preferred breeding habitat has reduced the availability and quality of preferred food plants. The species is therefore classified as Critically Endangered.
