It is endemic to Tahiti in French Polynesia. There are fewer than 50 individuals remaining.[2] Taxonomy and systematicsThe Tahiti monarch was originally described in the genus Muscicapa. Formerly, the Maupiti monarch was considered as a subspecies of the Tahiti monarch until re-classified as separate species in 2012.[3] DescriptionThis bird is 15 centimeters long and black in color with a pale blue bill. The juvenile is reddish brown. The call sounds like tick-tick-tick and the song is "flute-like".[2] Distribution and habitatThis bird is found in only four valleys in Tahiti. It lives in the canopy and understory in forests among mara trees (Neonauclea forsteri). ThreatsThreats to the species include the degradation of its forest habitat by the invasion of exotic plant species, including Miconia calvescens and Spathodea campanulata. The forest is also degraded by goat activity. Predation by rats and cats is a threat. The Tahiti kingfisher (Todiramphus veneratus) is a competitor.[2] References1. ^{{Cite journal |author=BirdLife International |title=Pomarea nigra |journal=The IUCN Red List of Threatened Species |volume=2016 |page=e.T22707178A94109906 |publisher=IUCN |date=2016 |url=http://www.iucnredlist.org/details/22707178/0 |doi=10.2305/IUCN.UK.2016-3.RLTS.T22707178A94109906.en |access-date=15 January 2018}} {{Taxonbar|from=Q1766815}}2. ^1 2 Pomarea nigra.
