dc.description.abstract Buteo solitarius is a medium-sized, light to dark brown, broad-winged hawk endemic to the island of Hawai'i. The hawk has been recorded by many observers at high and low elevations in all major districts of Hawai'i from 1778 through the present. Distributional records are shown by U.S. Geological Survey quadrangle. References and names of observers are cited. Completeness of data, bias, erroneous and doubtful records are addressed. Findings are summarized. It is suggested that a long-term population decline is occurring. Except for Hawaii Volcanoes National Park, where specific long-term census data have been collected, there is yet no factual basis from which the overall population size or future trend may be estimated. More information on the home range, life requirements, and population ecology of the 'Io is needed.
