Altitudinal migration and the future of an iconic Hawaiian honeycreeper in response to climate change and management
Alban Guillaumet, Wendy A. Kuntz, Michael D. Samuel, Eben H. Paxton
2017, Ecological Monographs (87) 410-428
Altitudinal movement by tropical birds to track seasonally variable resources can move them from protected areas to areas of increased vulnerability. In Hawaiʻi, historical reports suggest that many Hawaiian honeycreepers such as the ‘I‘iwi (Drepanis coccinea) once undertook seasonal migrations, but the existence of such movements today is unclear. Because...
