Name
  • Common name- Nihoa millerbird (old world warbler)
  • Scientific name- Acrocephalus familiaris kingi
  • Nick name- Old world warbler
Description
  • Animalia Phylum Chordata Subphylum Vertebrata
  • a 13 cm reed-warbler, dark olive and olive brown above with grayish margins on feathers; wing and retrices chaetura drab; whitish below with some grayish olive wash on both sided; and buffy brown flanks. Bill thin, blackish; tarsus and toes blackish gray. Sexes similar, but females slightly smaller.
  • These birds eat small insects and usally consist of grasshoppers and grubs. It lives on small islands in hawaii. Nests are made in small trees.
  • This bird lays eggs in a nest then sits on them to keep them warm.
Habbitat
  • This bird is only found on the hawaiian islands. It is found on a wide varity of islands in hawaii.
  • On Nihoa, Millerbirds are known to prefer dense cover near the ground, where they search for insects and larvae and build nests in dense shrubs.
  • These brieds are not migratory at all because if the tropical climate of hawaii
  • These birs do not hibernate eithier.
  • mosquitos are the biggest killer of these bird
Problom
  • As with any limited population, random events could have catastrophic effects. The tiny exposed island of Nihoa is especially susceptible to weather events, and weather events probably account in part for changes in Millerbird population estimates over the past 30 years. The fragile nature of this tiny ecosystem and the chance that human visitors could introduce an alien species are an ongoing cause for concern. At this time only 3 alien plants are thought to be established on Nihoa Island, and disease-bearing mosquitoes that have decimated other Hawaiian endemic birds have not become established on the island. Rats, mosquitoes, or new plants are all possible threats
Solutions
  • The species was federally listed as Endangered in 1967. The island of Nihoa is part of the Hawaiian Islands National Wildlife Refuge and access is strictly controlled through a permitting process. While visiting scientists make an effort to pull invasive weeds, no other substantive efforts on behalf of the Millerbird have been undertaken. The option of translocating Millerbirds to other islands (including Laysan, Necker, and Kaho'olawe) has been seriously considered, with the option of returning Millerbirds to Laysan receiving the most serious attention. Computer models show that the current population has an unacceptably high probability for extinction unless efforts are made to establish supplemental populations either on other islands or in captivity.
