Justification of Red List category
Recent analysis of trend data for the global population over the past three generations (64 years) gives a best case estimate of a 17 % increase and a worst case scenario of a 7.2 % decline (Chown et al. unpubl. report 2008); declines consequently do not approach the threshold for classification as Vulnerable and the species is listed as Least Concern.
