Puaiohi live only on the Hawaiian island of Kauai, where they are mostly found in forest habitat at elevations over 1,000 meters. They nest in cavities or crevices, usually alongside streams. They are non-migratory.
The Puaiohi can be recognized by its fairly non-descript overall drab olive-brown plumage. They have a white eye-ring. In adults, the bill is black adn the legs and feet are pink.
Details & Statistics
The Puaiohi is listed as Critically Endangered on the IUCN Red List and was last assessed in 2015 by BirdLife International. This species qualifies as Critically Endangered because it has an extremely small range, wholly confined to one upland area where habitat quality is continuing to decline. It has apparently always been rare, although the reasons for this are unclear and the range and population trends are difficult to judge, because it is extremely elusive, and occurs in some areas that are difficult to access. Reintroduction of captive-bred individuals has however led to a significant population increase and if declines in habitat quality are halted the species may be eligible for downlisting in the future.
