Population justification: The global population size has not been quantified, but the species is described as not uncommon (Gibbs et al. 2001).

Trend justification: The species is suspected to be have undergone a moderately rapid decline over three generations (20 years), owing to the impacts of introduced predators, collisions with vehicles and infrastructure, and illegal hunting. However, there has apparently been some recover as the population was considered to be increasing in 2012 (Robertson et al. 2013).
