Hawaii Island Kohala Mountain complex forest bird survey, 2017 Hawaii Island Kohala Mountain complex forest bird survey, 2017
This data release contains the point-transect distance sampling records of forest bird survey collected in the Kohala Mountain complex in 2017, including survey point IDs, distance to detected birds, sampling conditions, ohia phenology, habitat classifications and background noise levels. This data release consists of one tabular dataset.
Hakalau Forest National Wildlife Refuge, Hawaii Akepa point-transect survey, 2002 Hakalau Forest National Wildlife Refuge, Hawaii Akepa point-transect survey, 2002
This dataset contains the point-transect distance sampling records of Hawaii Akepa collected at Hakalau Forest National Wildlife Refuge in 2002, including survey point locations, distance to detected birds, number of detected birds, elevation, and alliance-level habitat classification. This data release consists of two tabular datasets, one that contains distances and the other that...
Alamagan, Commonwealth of the Northern Mariana Islands, Nightingale Reed-warbler point transect survey data, 2010 Alamagan, Commonwealth of the Northern Mariana Islands, Nightingale Reed-warbler point transect survey data, 2010
Point transect distance sampling data were collected during the 2010 surveys of Alamagan, Commonwealth of the Northern Mariana Islands (CNMI). Data were collected at points along transects where trained observers recorded the detection type (heard, seen, or heard then seen) and horizontal distance (exact distance in m) from the station center point to individual birds detected during an...
Kaloko-Honokohau National Historical Park, Hawaiian hoary bat acoustic activity and insect prey data 2013-2015 Kaloko-Honokohau National Historical Park, Hawaiian hoary bat acoustic activity and insect prey data 2013-2015
We examined habitat use and foraging activity of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus), as well as nocturnal aerial insect abundance at Kaloko-Hon kohau National Historical Park located in the coastal region of Kailua-Kona, Hawai'i Island. The study area covers approximately 486 ha of marine waters and terrestrial coastal plains. Hawaiian hoary bat echolocation
Lower Puna, Hawaii Island, bird and habitat surveys of 2003 and 2016 Lower Puna, Hawaii Island, bird and habitat surveys of 2003 and 2016
The newly identified rapid ohii death (ROD; Metrosideros polymorpha) originated in the lower Puna district and its distribution has spread across Hawaii Island. As ROD expands it is expected that the loss of the dominant tree species will adversely affect bird populations. This project is a first attempt to describe the relationship between the impacts of ROD on the Hawaiian avifauna...
Hakalau Bioacoustic Surveys and Models 2015 Hakalau Bioacoustic Surveys and Models 2015
In this study, we create and evaluate a protocol to estimate the density, which can be used to estimate the abundance of terrestrial sound-producing animals from single automatic sound recorders. The protocol uses cue rates from the target species as well as sampling conditions and an estimate of the distance of the individual to the recorder based on the power of the sound. We applied...

Automated methods for processing camera trap video data for distance sampling Automated methods for processing camera trap video data for distance sampling
Context Population monitoring is an essential need for tracking biodiversity and judging efficacy of conservation management actions, both globally and in the Pacific. However, population monitoring efforts are often temporally inconsistent and limited to small scales. Motion-activated cameras (‘camera traps’) offer a way to cost-effectively monitor populations, but they also generate...

Status and trends of forest bird populations at Hakalau Forest National Wildlife Refuge, 1987–2024 Status and trends of forest bird populations at Hakalau Forest National Wildlife Refuge, 1987–2024
Since 1985, the Hakalau Forest Unit of the Big Island National Wildlife Refuge Complex (hereafter, Hakalau) has protected the largest endemic forest bird diversity in the State of Hawaii. This includes three endangered and one threatened species and their habitats. Hakalau’s vast area (155 km2), mostly high elevation (>1500 m) montane forest, provides refuge from avian malaria...

Pacific island landbird monitoring report, Kalaupapa National Historical Park, 2021 Pacific island landbird monitoring report, Kalaupapa National Historical Park, 2021
In 2021, landbird surveys were conducted at Kalaupapa National Historical Park on the island of Molokaʻi to assess changes in species composition, distribution, and population densities since 2005. Point-transect distance sampling surveys were conducted on six transects at 50 landbird monitoring stations within an 1,834-hectare area. A total of nine landbird species were detected, with...

Fine-grained temporal population monitoring of a declining, critically endangered Hawaiian honeycreeper Fine-grained temporal population monitoring of a declining, critically endangered Hawaiian honeycreeper
Annual point counts are commonly used to monitor birds to track population densities across space and time. Palila (Loxioides bailleui) are surveyed annually in the first quarter, but we recently instituted quarterly sampling that offers a unique opportunity to improve estimator precision. We conducted point-transect distance sampling point counts during the first quarter of 2020 through...

Using distance sampling with camera traps to estimate densities of ungulates on tropical oceanic islands Using distance sampling with camera traps to estimate densities of ungulates on tropical oceanic islands
Reliable population estimates are one of the most elementary needs for the management of wildlife, particularly for introduced ungulates on oceanic islands. We aimed to produce accurate and precise density estimates of Philippine deer (Rusa marianna) and wild pigs (Sus scrofa) on Guam using motion-triggered cameras combined with distance sampling to estimate densities from observations...

2022–2024 Status and trends of the Palila (Loxioides bailleui) 2022–2024 Status and trends of the Palila (Loxioides bailleui)
Palila (Loxioides bailleui) are critically endangered Hawaiian honeycreepers specializing on the seedpods of māmane (Sophora chrysophylla) and restricted to Mauna Kea volcano on the Island of Hawaiʻi. A previous analysis of survey data estimated an 89% population decline between 1998 and 2021. Using the most recent annual survey data from 2022, 2023, and 2024, we report updated annual...
