A finch-billed Hawaiian honeycreeper endemic to the island of Laysan; does not occur in the main Hawaiian Islands. An introduced population occurs on Pearl and Hermes Atoll. Unlikely to be confused with any other species; the only other passerine bird on Laysan is the Millerbird, which lacks the Laysan Finch’s heavy bill. Males have a bright yellow head. Females are paler yellow and streaked.
