This species qualifies as Vulnerable because it has a very small breeding range. It is known from five locations in the main Hawaiian islands, and the future of at least two are in jeopardy (Mauna Loa and West Maui). Its limited distribution and declines primarily result from predation by introduced mammals and urbanisation.
