Kauai Bird Surveys (12 species) 1981-2012

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-27T00:00:00Z
Bird surveys were conducted in 1981, 1989, 1994, 2000, 2005, 2007, 2008, and 2012. From these data we calculated species-specific density and abundance estimates. We conducted separate trends assessments for the Interior (long [1981-2012] and short [2000-2012]) and the Exterior (surveyed 2000-2012) portions of the Alakai Plateau, and using abundance estimates for native species from 2000-2012, we fit a linear and exponential growth model to the population numbers of each species to evaluate time to extinction.
