Justification of Red List category

This widespread species declined historically in the southern parts of its range, primarily owing to the destruction and degradation of its preferred woodland habitat, predation by introduced foxes and interactions with habitat loss, however most of these declines occurred prior to the past three generations (32 years).  The species remains common in northern Australia, including in urban areas where there is no evidence of declines despite depredation from feral and domestic cats and dogs. As there is no evidence to suggest the species has undergone a moderately rapid population decline over three generations, and the species’s range and population are both large and do not approach any of the thresholds for classification as Vulnerable, it has therefore been downlisted to Least Concern.
