A collection of fully-annotated soundscape recordings from the Island of Hawai'i
<p>This collection contains 635 soundscape recordings with a total duration of almost 51 hours, which have been annotated by expert ornithologists who provided 59,583 bounding box labels for 27 different bird species from the Hawaiian Islands, including 6 threatened or endangered native birds. The data were recorded between 2016 and 2022 at four sites across Hawai‘i Island. This collection has partially been featured as test data in the 2022 BirdCLEF competition and can primarily be used for training and evaluation of machine learning algorithms.</p> <p><strong>Data collection</strong></p> <p>Soundscapes for this collection were recorded for various research projects by the Listening Observatory for Hawaiian Ecosystems (LOHE) at the University of Hawai‘i at Hilo. The recordings were collected using Wildlife Acoustics Inc. Song Meters (models 2, 4, or Mini), as 16-bit wav files at a sampling rate of 44.1 kHz, using the default gain settings of each model. Further specifics for each recording, such as recording location and habitat type, can be found in the metadata provided. Soundscapes in this collection vary in length, ranging from just under a minute to 9 minutes in duration. All audio was unified, converted to FLAC, and resampled to 32 kHz for this collection. Parts of this dataset have previously been used in the 2022 BirdCLEF competition.</p> <p><strong>Sampling and annotation protocol</strong></p> <p>This collection is a subset of the files recorded over the course of the LOHE lab’s respective studies. The data were subsampled for annotation by aurally scanning the recordings and visually scanning spectrograms generated using Raven Pro software for target species of interest to the individual research project for which each recording was collected. Recordings that did not contain vocalizations of the species of interest were excluded from full annotation and thus this collection. </p> <p>Using Raven Pro, annotators were asked to create a selection box around every bird call they could recognize, ignoring those that were too faint or unidentifiable at a spectrogram window size of 700 points. Provided labels contain full bird calls that are boxed in time and frequency. Annotators were allowed to combine multiple consecutive calls of the same species into one bounding box label if pauses between calls were shorter than 0.5 seconds. We converted labels to eBird species codes, following the 2021 eBird taxonomy (Clements list).</p> <p><strong>Files in this collection</strong></p> <p>Audio recordings can be accessed by downloading and extracting the “soundscape_data.zip” file. Soundscape recording filenames contain a sequential file ID, site ID, recording date, and timestamp in HST. As an example, the file “UHH_001_S01_20161121_150000.flac” has sequential ID 001 and was recorded at site S01 on Nov 21st, 2016 at 15:00:00 HST. Ground truth annotations are listed in “annotations.csv” where each line specifies the corresponding filename, start and end time in seconds, low and high frequency in Hertz, and an eBird species code. These species codes can be assigned to the scientific and common name of a species with the “species.csv” file. The approximate recording location with Universal Transverse Mercator (UTM) coordinates and other metadata can be found in the “recording_location.csv” file.</p> <p><strong>Acknowledgements </strong></p> <p>Compiling this extensive dataset was a major undertaking, and we are very thankful to the domain experts who helped to collect and manually annotate the data for this collection.

Avian botulism is a primary, year-round threat to adult survival in the endangered Hawaiian Duck (Anas wyvilliana) on Kaua'i, Hawai'i, USA
<p>Adult survival is the most important demographic parameter influencing population dynamics for many bird taxa. Thus, understanding how survival probabilities and causes of mortality vary throughout the annual cycle is critical for developing informed and effective management strategies. In this study, we used radio-telemetry data to evaluate the effects of biotic (e.g., sex, peak [September–April] vs. off-peak [May–August] nesting seasons) and abiotic factors (e.g., rainfall, year, bi-monthly interval) on adult survival, estimate annual survival probabilities, and identify primary sources of mortality for Hawaiian Ducks (<em>Anas wyvilliana</em>), an endangered, non-migratory dabbling duck, on the island of Kaua'i, Hawai'i, USA over 2013 and 2014. Additionally, we used contemporaneous Hawaiian Duck carcass recovery and surveillance data to examine temporal and climatic associations with avian botulism outbreaks. Our results suggested bi-monthly survival decreased with total rainfall during the preceding two-month interval. Survival did not vary with sex, between peak and off-peak nesting seasons, or between the two years of this study. Annual survival probabilities (62–80%) were relatively low compared to the closely related Laysan Duck (<em>Anas laysanensis</em>) on Laysan Island. Primary causes of mortality included avian botulism and presumed predation by cats (<em>Felis catus</em>). The botulism surveillance dataset revealed support for the effect of rainfall on the number of sick and dead birds recovered (<em>n</em> = 216), with generally a greater number of recoveries during months with middle-range total rainfall during the concurrent and preceding months. Our study provides critical baseline demographic data for population monitoring and highlights the importance of managing botulism risk and non-native mammalian predators for the recovery of the endangered Hawaiian Duck.</p>

<p>Vertical displacement (velocity) maps of Kilauea (Hawai`i, USA) derived from InSAR, for the time periods 2014-2017 and 2018. Vertical velocity data were obtained by processing Sentinel-1 ascending and descending SAR data (tracks 124 and 87, respectively). Data were processed using the JPL-developed InSAR Scientific Computing Environment (ISCE) open-source software package, and further time-series analysis was performed using the MintPy software toolbox (Miami INsar Time-series software in PYthon), developed at the University of Miami. An SRTM-derived Digital Elevation Model is also provided. </p> <p>These data were generated for figures in: Farquharson, J. I. and Amelung, F.

Figure 2. Male Megalagrion xanthomelas perched on pickleweed (A), a tandem pair of M. xanthomelas perched on a small branch (B), and four of the core pools where M. xanthomelas were surveyed (C–F). Note that the female M. xanthomelas (B) is probing the tip of her abdomen on the side of a branch that is above the surface of the water. The wetness of the branch suggests that it will be submerged during high tide.

Hourly detections of echolocation clicks in Hawaiian Island HARP data from Hawai`i, Kaua`i, and Manawai with species labels
<p>This dataset consists of counts of detections of echolocation clicks at three sites in the Hawaiian Islands Archipelago. These sites are Hawaii, Kauai, and Manawai (also known as Pearl and Hermes Reef). Echolocation clicks have been labeled using a neural network classifier that was trained and tested on data from the Hawaiian Islands and can successfully identify many species of regionally present odontocetes. During the labeling process, clicks were grouped into one-minute bins and each bin was given a species' label. The data provided here is further binned at an hourly level, where counts of a given species represent the number of one-minute bins within a given hour that were labeled as that species (up to a maximum of 60). One file is provided per site, and files are in .csv format that can be read using any desired coding language.<span> </span></p>
