Pacific Island Bird Survey Design and Data Analysis
Abundance data are collected for bird populations throughout the Pacific Islands by numerous federal, state, university, and non-profit organizations. In order to ensure data are standardized and available to researchers throughout the region, interagency bird databases have been created and continue to be used. These databases contain more than a million compiled, proofed, and standardized...
Advancing Wildlife Monitoring to Improve Management of Endangered Hawaiian Birds in a Changing Climate
Mosquito-borne disease is the biggest threat to Hawai‘i’s remaining native forest birds, of which more than half are threatened or endangered. Currently, disease-carrying mosquitoes are unable to move into colder high-elevation forests, but as the islands warm due to climate change, mosquitoes are steadily moving into the last native bird strongholds. Mosquito suppression efforts are...
Global Climate Change Impacts on Plants of Hawai‘i Volcanoes National Park
Climate change is expected to alter the seasonal and annual patterns of rainfall and temperature in the Hawaiian Islands. Warming temperatures and altered precipitation patterns both impact ecological systems, but managing these impacts is difficult without detailed information on the magnitude and timing of these climate-related changes.
Assessing the Potential Effects of Climate Change on Vegetation in Hawaiʻi Volcanoes National Park
Climate change in Hawaiʻi is expected to result in increasing temperatures and varying precipitation through the twenty-first century. Already, high elevation areas have experienced rapidly increasing temperatures and there has been an increase in the frequency of drought across the Islands. These climatic changes could have significant impacts on Hawaiʻi’s plants and animals. Changes in

Hawaiian Islands Hawaiian Forest Bird Surveys (HFBS) bird counts and vegetation maps 1976-1983 Hawaiian Islands Hawaiian Forest Bird Surveys (HFBS) bird counts and vegetation maps 1976-1983
In 1976-1983, the U.S. Fish and Wildlife Service conducted systematic surveys of forest birds and plant communities on all of the main Hawaiian Islands as part of the Hawaiian Forest Bird Surveys (HFBS; Scott et al. 1986). Results of this monumental effort have guided conservation efforts and provided the basis for many plant and bird recovery plans and land acquisition decisions in...

This USGS data release consists of six data sets and accompanying metadata for a year-long study on the seasonal distribution and relative abundance of the southern house mosquito Culex quinquefasciatus in Kīpahulu Valley, Haleakalā National Park, critical habitat for two endangered Maui endemic forest birds. Culex quinquefasciatus is the vector of the avian malaria Plasmodium relictum...

The continued decline of the Palila (Loxioides bailleui) on Mauna Kea, Island of Hawaiʻi The continued decline of the Palila (Loxioides bailleui) on Mauna Kea, Island of Hawaiʻi
Palila (Loxioides bailleui) are critically endangered Hawaiian honeycreepers specializing on māmane (Sophora chrysophylla) seeds and restricted to Mauna Kea volcano on the Island of Hawaiʻi. Recently, the population was estimated to decline by 89% between 1998 and 2021, despite decades of ungulate removal, fence construction, māmane regeneration, fire suppression, and predator control...

Quantifying landscape-level biodiversity change in an island ecosystem: A 50-year assessment of shifts in the Hawaiian avian community Quantifying landscape-level biodiversity change in an island ecosystem: A 50-year assessment of shifts in the Hawaiian avian community
Hawaii has experienced profound declines in native avifauna alongside the introduction of numerous bird species. While site-specific population studies are common, landscape-level analyses of avian population dynamics are rare, particularly in island ecosystems. To address this gap, we used a density surface model to create a spatio-temporal projection of population densities and...

Breaking down Palila decline: Assessing the role of drought and vegetation health in the population loss of an endangered Hawaiian honeycreeper Breaking down Palila decline: Assessing the role of drought and vegetation health in the population loss of an endangered Hawaiian honeycreeper
The Palila (Loxioides bailleui), the last member of the once speciose finch-billed Hawaiian honeycreeper clade (Drepanidinae) in the main Hawaiian Islands, faces critical conservation challenges as an endangered species. Understanding the drivers of its decline is essential for effective management. We used additive decomposition models to examine temporal trends in climatic variables...

Disease-driven collapse of the native Kauaʻi avifauna and the rise of introduced bird species Disease-driven collapse of the native Kauaʻi avifauna and the rise of introduced bird species
Hawaii hosts one of Earth’s most unique and threatened avifaunas. Upslope migration of mosquito-vectored avian malaria on Kauaʻi (maximum elevation 1,598 m) has likely caused its rapid loss of avifaunal diversity; only 8 of 13 historic forest bird species remain. We update the status and trends of Kauaʻi forest bird populations since the original (1981) surveys using the latest (2023)...

Since the introduction of the Golden Pheasant (Chrysolophus pictus) to Haleakalā volcano, Maui, three decades ago, subsequent reports have hinted at an expansion of this nascent population. We draw from a variety of data sources to learn about this pheasant's present status on Maui. First, forest bird surveys conducted every five years revealed that the frequency of Golden Pheasant...
