Conservation status

Thrity-six species of Monarchidae are listed in The 2000 Red List of Threatened Species. Many are endemic to single islands in Southeast Asia. Five species are Critically Endangered, the rarest being the Tahiti monarch (Pomarea nigra), with only a handful of individuals remaining by the late 1990s. Loss of wooded habitat is the principal cause of population decline among the family. Two species are already extinct, in cluding the Guam flycatcher (Myiagra freycineti), which was common on the Pacific island of Guam until the 1970s but crashed to extinction in 1983 as a result of predation by the introduced brown tree snake (Boiga irregularis).
