- Summary:
- we examine how carotenoid-based plumage coloration and sexual dichromatism of the Hawaii Amakihi (Chlorodrepanis virens) varies with rainfall and temperature on Hawaii Island. Study sites include North and West of Mauna Kea. We found that the plumage coloration of Hawaii Amakihi varied with both temperature and rainfall but sexual dichromatism was not affected by the climatic conditions. This study provides evidence that rainfall and temperature play an important role in determining the plumage traits of Hawaii Amakihi.
