The millerbird (Acrocephalus familiaris) is a species of Old World warbler in the family Acrocephalidae. It had two subspecies, A. f. kingi and A f. familiaris. The latter, the Laysan millerbird, became extinct sometime between 1916 and 1923. The former, the critically endangered Nihoa millerbird, remains the only race left, inhabiting the small island Nihoa in Hawaiʻi. It is the only Old World warbler to have colonised Hawaiʻi, although there is no fossil evidence that the species ever had a distribution beyond these two islands. Order: Passeriformes, Family: Acrocephalidae, Species: Acrocephalus familiaris (Rothschild, 1892)
