This charismatic species is believed to be declining because of predation by, and competition with, various introduced mammals. It is widely acknowledged that it is very hard to accurately estimate its population size; however, the estimates available generally indicate that the population could be small. For these reasons it is listed as Vulnerable. Now that a monitoring method has been devised, it is hoped that current trend and population estimates can be improved upon.
