The Kahuku Unit of the Hawai`i Volcanoes National Park (HAVO) was surveyed for native and non-native birds from January to September of 2005. Bird habitat comprised of forest, woodland, and grassland was divided into five separate regions, and these were surveyed with variable circular plot count methodology to generate estimates of abundance and occurrence. Sampling coverage was more intensive (i.e. several times more count transects and stations) than in past surveys, for more accurate estimates of range and population size. In addition to point counts, we recorded incidental observations to supplement the survey. The database contains detection data from the inventory for all bird species except the three endangered species (Hawaii Akepa, Hawaii Creeper, and Akiapolaau). Also included are the GIS shapefiles of the transects that were surveyed for the inventory.
