Change in mass of birds pre- and post-koa moth outbreak, Hawaii Island, 2013-2014

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2021-02-17T00:00:00Z
Bird banding at 2 locations adjacent to one another (one in koa restoration forest, and other in native intact forest) at Hakalau Forest National Wildlife Refuge before and after the start of an outbreak by koa moths (Scotorythra paludicola) during 2013. Each bird was measured with an electronic scale accurate to 1/10th g. Results indicate that insectivorous birds increased in mass, on average, while generalist diet species showed marginally significant increases, and two out of three nectarivorous and frugivorous birds did not have significant change.
