Title: Proposal for the study of rare and endangered birds in Hawaii’s National Parks

Abstract: Half of all the rare and endangered bird species listed in the Department of the Interior’s Red Book of Rare and Endangered Species are Hawaiian birds. Some of these are still found within the boundaries of the parks and others were found there during the past 35 years. A base-line study for three of the nost common species (Amakihi, Apapane, Iiwi) of honey-creepers exists as the result of the work of Paul H. Baldwin (1953. Univ. Calif. Publ. Zool., 52(4): 285-398) in Hawaii Volcanoes National Park during the 1940’s, although his work was based almost exclusively on an examination of gonads in collected birds. A second, preliminary survey is found in IBP technical Report No. 8 (Birds of Hawaii Volcanoes National Park, August 1972) by Berger and shows striking changes in Baldwin’s work. However, there has never been conducted an intensive field study of the annual cycle of the endemic bird species within the Parks, and only one (on Kauai) has thus far been attempted on any of the Hawaiian Islands. Although there has been much speculation as to the causes of the extinction and/or reduction in numbers of many of the species, we are still waiting for a thorough and reliable study of the external and internal parasites and diseases of birds in Hawaii, both endemic and introduced. We do not know the limiting factors in the annual cycle for any endemic bird species; we do not have detailed information on the frequency of destruction of eggs, young or adults by mongoose and rats; nor do we have precise information on the relationships between the introduced birds and the native species.
