Summary:

Psittirostra bailleui is a small, yellow and gray forest bird with a short, thick brown bill. It is endemic to the island of Hawaii. This report summarized the exhaustive search of literature and field journals etc. on relative abundance and geographical distribution from 1876 to 1978. In the 1890's Palila were observed to be common to abundant in upper elevation forests along the western flank of Mauna Loa and on the north, northeast, and southeast slopes of Mauna Kea. Intensive surveys on Mauna Kea by the U.S. Fish and Wildlife Service and cooperating agencies in 1975 resulted in finding a population of about 1,600 individuals on all except the northwest and north slopes. A few observational clues since 1950 suggest that Palila population and range continue to decline long-term.
