apteribis
''Apteribis'' is an extinct genus of flightless birds in the ibis subfamily that was endemic to the Hawaiian Islands in the Pacific Ocean.
==Distribution==
The remains of the small ibises in the genus have only been found on the islands of Maui and Molokai, which formed part of the prehistoric island of Maui Nui until about 200,000 years ago when rising sea levels fragmented it. Olson and James speculate that the genus was endemic to Maui Nui, that the ibises were birds of the forest floor, that because of their flightlessness they were susceptible to becoming trapped in lava tubes, and that they may have exerted heavy predation pressure on Maui Nui’s land snails.〔
