Honeycreeper samples included in this study. Samples were collected at nine sampling locations on the eastern slopes of the Mauna Loa and Kilauea volcanoes of the island of Hawaii. Low elevation (< 300 m above sea level) sites include Bryson's Cinder Cone (low-BRY), Malama Ki Forest Reserve (low-MAL), and Nanawale Forest Reserve (low-NAN). Mid elevation sites (between 1,000 and 1,300 m above sea level) include Cooper's (mid-COO), Crater Rim (mid-CRA), Pu'u Unit (mid-PUU), and Waiakea Forest Preserve (mid-WAI). High elevation sites (more than 1,650 m above sea level) include C. J. Ralph (high-CJR) and Solomon's (high-SOL). The numbers of samples of each species collected at each site are shown.
