They suspected that the population is declining in general Since the largest subpopulation, lathami, It is slowly decreasing throughout its range. However it is believed that the subspecies Erebus is increasing and the subspecies halmaturinus It is increasing as a result of conservation efforts in the Island Ganguro (Garnett and Crowley 2000).
