Hawaiʻi Volcanoes National Park (HAVO) was surveyed for landbirds and landbird habitat from February through April 2015 and February through April 2016. This information provides the second datum in the time-series of Pacific Island Network (PACN) monitoring for long-term trends in landbird distribution, density, and abundance. Initial PACN surveys were conducted in 2010 and are repeated every five years. The entire survey area was comprised of eight tracts in forest, woodland, and shrub habitat, totaling 26,364 ha. Each tract was surveyed using point-transect distance sampling to calculate estimates of bird abundance and density. In addition to the permanent PACN survey transects, randomly generated point-transects...

Hawaii forest birds nesting in Hakalau Forest National Wildlife Refuge were exposed to models of predators near their nests to measure behavioral responses. Responses to potential nest predators included vocalization rate, movement behavior, and nestling feeding. Predators were inert stick, introduced but abundant predator, a rat, and a novel predator, a snake, that does not occur on Hawaii.

Lotek Pinpoint Global Positioning System (GPS) Argos Satellite tracking tags were placed on 4 Hawaiian Stilts on Oahu island in 2017. The birds were tracked from 19 July 2017 to 12 February 2018, with locations taken daily every 1.5 hours from 0400 to 2000 Hawaii Standard Time. For each location, a description of the general habitat as 1) Wetland, 2) undeveloped field, 3) sport field, and 4) developed area was determined through a visual evaluation of the location using WorldView-2 satellite imagery.

Dataset includes publicly available geologic and rainfall data, and environmental and ecological data derived or collected for this project. Specifically, water infiltration measurements, interepreted field-saturated hydraulic conductivity values, ungulate activity, vegetation cover, general soil and weather conditions data are included. Soil samples were collected, lab analyzed, and are included in the dataset. Field-collected data are associated with plots that encompassed approximately a 3 x 3 m area; site data represent approximately 20 x 20 m. First posted: 4 March 2020 (available from author) Revised: April 13, 2020 (version 2.0) The revision is provided due to minor refinement of the dataset and updated...

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 our protocol to estimate the density of two Hawaiian forest bird species (Hawaiˊi ˊamakihi, Chlorodrepanis virens and ˊōmaˊo, Myadestes obscurus) on the island of Hawaiˊi, USA. We validate our approach by comparing our density estimations with others calculated at the same stations using a traditional point-transect distance sampling...
